How to scan a tabletop miniature for the Tabletop Simulator (Part 1)

Last update: August 16, 2022

In this tutorial series I would like to show you how to convert your tabletop miniatures into a 3d model and load it into the Tabletop Simulator. And all this with completely free software.

This first part will cover the image creation and the 3d scanning. At the end of this part, you will have a readily textured, lowpoly 3d object. This part is the most important one but can be accomplished by anyone who can shoot some sharp images. Bear in mind, that the final 3d object will not be a hand modelled game asset. The scan software does an awesome job to fetch even the tiniest details, but it will create a triangulated mesh, which cannot be easily modified afterwards.

If you only want to digitalize an object, the first part of the tutorial is sufficient. The other two parts are only interesting if you want to bring the scanned object into the tabletop simulator as a game asset.

In the second part I will deal with minor adjustments on the model, especially the base part. If you don’t need that, you can simply skip these parts.

The third and last part covers the necessary steps of importing the 3d object into the Unity game engine. Here we will do the final touches, add a collider mesh and export it as an assetbundle. We will then load this file into the Table Top Simulator.

Ok, so that is the plan. Let’s get started 🙂

Part I: Preparation and scanning

I.I What do you need

First of all, let us have a brief look at the requirements:

An object to scan

This tutorial is about tabletop figures, so this should the object of choice. In general you can also scan bigger things, but in this tutorial i talk about simple 28mm scale figures.

A camera

I really recommend using an DSLR camera since they have a larger photo sensor which is good to produce noise free images. Another very big advantage is the possibility to adjust focus and exposure manually.
Miniatures are small objects and it can be hard get a sharp image from all parts of the miniature at once. Especially in situations where parts are pointing towards the camera. The automatic focus will adjust on the nearest part (like a weapon barrel or a stretched out arm) or the rest, switching to manual mode can help to ease it out a bit.
Finding the right exposure value can also be much easier with manual adjustments. After struggling with the programs of my Canon EOS 350D, i switched to full manual mode for the exposure and f-stop settings, and never looked back.

What settings should you use?

Camera settings always require a good balance of shutter speed, f-stop and ISO setting. Each one influences the others:

  • A high aperture is important when shooting tiny miniatures. It significantly reduces blurring as it improves the depth of field.
    However, it darkens the image and therefore requires the slowest possible shutter speed.
  • A slow shutter speed, on the other hand, requires a tripod, as otherwise the image will inevitably be blurred again.
  • Additionally, it helps to increase the ISO number, the light sensitivity. But higher ISO can produce noise in the image.

Two examples:

Shutter speed: 1/60
f-Stop: 5.6
ISO: 400
Shutter speed: 1/20
f-stop: 22
ISO: 1600

As you can see, the image to the right is much sharper than the one to the left, but requires heavy adjustments in terms of shutter speed and ISO to achieve the same brightness. You will need a tripod, too.

To be honest, i am not a photographer at all, i shot all my photos with the settings in the left image. Shame on me, but i achieved good results and all photos in this tutorial are taken with these settings.

But if you want to have perfect images, go the other route and set the f-stop as high as you can get with your equipment. (Thanks to Axel Castellan, a very talented photographer and miniature painter, who shared some insights with me)

Optional, but highly recommended: A turntable setup with a fixed light

To get consistent results in terms of equal lighting on your miniatures and in order to ease the process of taking the photos, i recommend you to use simple setup with a good lamp with high light temperature and some sort of turntable. A black backdrop behind your setup also helps a lot to avoid unwanted texture issues on your scanned object. This is my simple setup:

I built this simple turntable (20 cm in diameter) out of some polystyrene plates (Depron) and put it under a strong LED lamp. This way i can turn it the exact amount and keep an equal lighting.

I am using a cheap LED lamp with a light temperature of 5600 Kelvin and a brightness of 1200 Lumen. A color temperature of around 6000k is optimal, lower temperatures will produce a yellow tint on your models, higher ones will make everything blue. My lamp produces a slightly yellow tint, so i set a manual white point in my camera to counter that.

We will talk more about the process of the image creation later, for now let’s have a look at the required software.

3DF Zephyr scanning software (free version)
( )
The free version is limited to 50 photos per project. What that means is, that you load 50 images into Zephyr, which will build a 3d model baes on the image information. 50 images are absolutely sufficient for our needs.

Unity engine in version Unity 2019.1.14f1 from August 9, 2019 (free) and the TTS sample project file ( )
This is needed if you plan to get your scanned model into the Tabletop Simulator (TTS).

Important: TTS received an update and is now utilizing a newer version of Unity . It is recommended to update to Unity 2019.4.23f1 if you already worked with older versions. However, content created using that older version should work as intended. At the time of writing (July 2021), newer versions than 2019.4.23f1 are not supported by Tabletop Simulator.

3d application e.g. Blender (free)
I own a copy of 3ds max, but the shown things can also be down in a free app like blender.

I.II Before the photo shooting

Ok, i assume you have your equipment ready and all necessary software installed. Now, before we start doing things, let’s talk about the best way of creating the imagery.

The scanning software requires as much information about the object as it can get. That means we will have to shoot photos from all angles to cover all areas of the object. It also requires about 60% to 80% of overlapping between two photos so it can get an idea of the position and the shape of the object. (Check out the 3DF Zephyr homepage, there are very useful tutorials about that topic)

If we fail to do this, we will get untextured spots on the model, or even worse geometry errors. We do not want that.

To take the photos, you can move around the object and photograph everything freehand or take the photos from a static position and rotate the object itself by a fixed amount.

I would highly recommend the second option, as it provides a consistent lighting situation for the whole range and allows you to cover all of the object in a more systematic way.

The best way to take the required photos is to shoot two series of 25 photos each that form a circle around the object. Each series is shot from a different angle to avoid blind spots.

The first series should be taken from slightly above the object to cover the upper part, like this:

The second series should be taken at eye level to cover the lower parts of the object, e.g. the underside of raised arms, weapons at aim, etc., like this:

We will not be able to photograph places at the underside. At such places, Zephyr will mix the texture of the object with its surroundings. This will also occur in blurred image areas.
To make these issues less visible, i designed some templates, that you can cut out and glue on top of your turntable . If you use them, Zephyr will darken these problematic areas. So they will get much less noticeable later.

The templates will also help you to position your object just in the middle. With the scale on the edge you can rotate your turntable by exactly 14.4 degrees for each photo. This will give you a full rotation for 25 photos.
I made a version for round bases, optimized for Infinity and one for DBA, which requires rectangular bases. You can get them here.

Glossiness matters:

When you print out the template using a normal inkjet printer and normal paper sheets, your blacks might appears a bit to bright.

I would recommend to print it on glossy paper, or paint it with gloss varnish (i used the latter one) to achieve less light scattering on the surface and a good black color. See the images below for comparison:

As you can see, the turntable now appears much darker, because the glossy coating changes its reflection behavior. Due to the flat angle, the lights of the studio setup are not reflected either. However, the miniatures themselves should not be treated with gloss varnish, as unwanted reflections can become visible here. You will then get unattractive white spots on your miniature. I therefore recommend not to paint the miniatures with glossy varnish before scanning them. If this has already happened, you can add a layer of matte varnish to soften the reflections.

Important notes:

  • As i mentioned earlier, the most important thing is to produce sharp and well lit images. If you get this right, all is good. If not, the scan software will produce blurred textures, or skip the images entirely.
  • Your light setup should cover the front and top of your miniature. Try to avoid dark areas. Use a lamp with a high color temperature, around 6000K.
  • Try to shoot the photos under reproducible conditions. Indoor shots and shots with covered windows help to avoid unwanted influences such as ambient lighting from sunlight or other sources that can change over time.
    Especially if you want to scan a series of objects, you want to be able to recreate the very same setting each time.
    For that reason i also measure the distance from my lamp to the tabletop (25 cm in my case) before starting to take photos.
  • Use my provided templates or something similar for the underground. The software needs to create reference points in 3d space to measure distances and create the shape of the target object. So the little markings on a black underground are much better than a pure white tabletop. Zephyr will struggle there.
  • NEVER move your object from its ground position during the photo shooting! It has to remain in the very same position, otherwise the scanning software will produce wierd results.

Okay, but enough theory. Let’s take some pictures and see how we can make a 3d object out of them!

I.III 3d Scanning in 3DF Zephyr

Ok, now we took our 50 photos, the hardest part is done now 🙂 . For this tutorial I chose a Zhanshi from the Infinity tabletop game.

The scanning process in 3DF Zephyr is done in several steps:

  1. Import the photos
  2. Create a sparse point cloud from the photos
  3. Build up a dense point cloud and from that a 3d mesh
  4. Clean the geometry and turn it into a low poly model
  5. Create the final textured mesh
  6. Export the model with its texture as an obj file

In the following I will now show every step of my workflow and all settings. I won’t explain every parameter, for that you better have a look at the documentation of 3DF Zephyr. Surely you can do one or the other better, but with these settings I got very good results.

Update (July 2021): 3DZephyr received an update to version 6.005. Menues changed a bit as new options were added. I haven’t tried the new options yet, but overall I could see an improvement in scan quality. The following screenshots still show the older version, but the mentioned options are also available in the new version and still valid. The Unity screenshots are from an older version as well, but the mechanics stayed the same.

Update (August 2022):

Since I wrote this tutorial, there have been several updates to 3DF zephyr that have greatly improved this tool.
Among other things, the documentation and presets have become really good, making the steps of the scanning process described below almost obsolete.

Lately I have been scanning a lot of miniatures for my Hail Casear project. Shiny armor and long thin spears are a nightmare to scan and despite a lot of fine tuning of the settings I have to admit to my shame that current presets give a better result.
That doesn’t mean that the settings described below don’t work. They do and even if some of the illustrations are outdated, the values are still valid.

Nevertheless my recommendation is the following:
If you have a lot of patience, you can surely find the perfect settings for many situations and be faster: -> Use the tutorial steps and start tweaking if something does not work

If you want to make it easy for yourself: –> Use the presets. Select the category „Human Body“ in the presets of 3d Model Generation and „Ultra“ as preset type. So far it has given me consistently very good results.

Otherwise a big thumbs up to all who scanned their minis for the tabletop simulator, you did a great job for the community!

1. Import the photos

Optional 1. Optimize your photos

You can in most situations improve the scanning process and the final look of your model, if you alter the images in an application like photoshop. I almost always process my images in the Camera Raw module of photoshop to darken the black areas, raise the contrast and modify the color temperature. Lower temperatures like 5000k will produce a blueish tint, that is quite cool for sci-fi models, for my ancients i rather choose a higher temp like 5800k to get a warmer, more yellow look. Get my XMP File with the 5800k setting for Photoshop here and adapt it to your liking.

However, i marked this step as optional for 2 reasons.

  1. If there are very bright areas (painted light effects or just reflections from your lighting setup) on your model, raising the contrast will make things worse and 3DF Zephyr might run into trouble producing indents or holes in your model like shown below.

If you encounter these problems, better use your unmodified images. It will produce slightly better results. However, you still might need to fix it in a later step in a 3d app like blender.

2. To achieve a crips look with high color contrast you can also modify the texture created by 3DF Zephyr after the scanning is completed. This will produce almost the same result.

1a. Start 3DF Zephyr and go to Workflow > New project:

1b. Click „Next“ and load the images into the project.

1c. 3DF Zephyr will now determine the camera in use and calibrate itself accordingly. Click on „Next“.

2. Create a sparse point cloud

2a. Now we will perform our first scanning step, the sparse point cloud creation. This will be the first representation of our model in 3d space.

Switch the settings mode to advanced and enter the settings shown below. After that, click „Next“

Important Note: Setting the Keypoint density to high or very high will guarantee a good result. However, this also means long calculation times. As long as your images are of good quality you can also set it to low or even very low. This will greatly reduce the computing time. (Thanks go to WonderSlug, a tireless member of the 3D infinity miniatures team, for this info)

In case you get positioning errors, check the angle from which you shot your lower series. It might be too low. Also try to avoid shooting the rim of your turntable, Zepyhr might get confused by that.

2b. Hit „Run“ to start the processing.

Depending on your pc hardware, the calculation can take some time.

On the results screen, you can see if all images could be processed. If the software skipped an image, it might be too blurry or be shot from a too different position than the rest of the series.

Remember between two photos there should be a large overlap, so the
software can build a three dimensional network between the photos to get an idea of the space and the contained objects.

In this case everything went fine. If you got a image skipped here and there, it will not matter that much. But if a series of successive images could not be processed, areas of your miniature will not be captured properly. In this case, you should make new images and repeat this step.

Now you can see the first three dimensional representation of your object in the viewport. The blue markers around indicate the camera positions from which a shot was taken. If you click on it, the perspective jumps to the camera position and the photo source is highlighted. This is a good way to understand, where Zephyr got its information from and why it built the mesh like it did. You can clearly see how the camera positions form two circles around the object.

As i mentioned it earlier, in case you get camera positioning errors, check the angle from which you shot your lower series. In most cases, it will be too low. Also try to avoid shooting the rim of your turntable, Zepyhr might get confused by that.

(Updated content 05/20): After creating the sparse dense cloud, we can already reduce the area that will be computed in the next steps. As you can see, Zepyhr scanned parts of the tabletop as well. We can erase that to speed up the process. (Thanks to

2c. Choose the bounding box tool from the main tool bar:

A box gizmo will appear around your scanned object. Reduce the size of the box so that it just contains your area of interest.

Make sure not to cut away parts of your miniature. All content outside the box will be skipped in the next steps. If you are careful enough, you could even get rid off the floor completely by lifting the underside of the box a bit. But pay attention not to cut parts of the base away, it will be important for bringing the whole miniature to the right scale.

Close the bounding box tool menu and proceed with the next steps.

3. Create dense point cloud and 3d mesh

3a. Now we will proceed with the next step. Go to Workflow > 3D Model Generation


Update 08/2022:
Switch the settings mode to „Presets“. Select the category „Human Body“ and „Ultra“ as preset type.

Click „Next“. After that, hit „Run“ and wait until it is finished.

The reconstruction is completed. We can now see our scanned model in the viewport.. As you can see, parts of the floor got scanned as well.

If you manipulated the size of the bounding box, it might look like that:

4. Clean the model

4a. In most cases you will need to get rid of the floor and maybe other unwanted meshes. To do that, we use the selection and delete tools we see on the right side. In the video I show my usual procedure. At first I choose a top view to roughly cut out the figure. Then I use the Plane tool to select and delete the rest of the floor.

You may have noticed, that i edited a copy of the scanned model. In the panel to the left, you can right click your mesh and clone it. This way you keep the original, in case something goes wrong or you want to experiment and with different settings. For the following steps i always clone the object before i proceed.

4b. First we will optimize the object. Right click the entry „Mesh 1“ on the left side and choose „Filters > Retopology“ Leave the settings at the default values and press „Clone and apply filter“

Now the filter will be applied on a copy of our original model. You can switch the visibility on and off in the 3d workspace by marking the little orange box. This way you can compare the changes to the original mesh. This will become very useful in the last step. But before that we need to change our high polygon mesh in a game friendly low ploy object.

4c. Choose the newly created Mesh 1 filtered1 and select „Filter > Decimation“

4d. The maximum vertex count for objects in TTS is 25000. So enter 25000 and hit „Clone and apply.“

5. Create the final textured mesh

4e. Now we want to create a textured mesh. This is the last step in 3DF Zephyr. It will create the final texture so we can finally export the 3d model.Go to Workspace and select „Textured mesh generation“

4d. Leave all cameras selected and hit „next“. Switch to advanced mode and enters the settings below.
You can play around a bit with the texture parameters, until you get your desired result. Too much sharpening will make your texture too crisp. The Blurriness weights option might be helpful, if parts get too much blurred.

I am quite satisfied with my scanned Zhanshi. Now we can export it as an obj file and close 3DF Zephyr.

6. Export the final model

13. Right click your Textured Mesh and choose „Export“

Enters these settings and hit „Export“. 3DF Zephyr will now create three files: The obj file that contains the pure 3d mesh, a JPEG file for the texture, and a mtl file, that contains the path reference and links the texture to the 3d model.

The end of part I

Now you have created a 3d model from a few pictures. This ends the first part of this tutorial.

      1. Thank you for your answer!

        About photographing the miniatures: Is it better to keep the background blurry or everything in focus?

        1. The background does not matter that much. It should have an uniform, dark color anyway. To get the best scanning results, try to get your miniature in focus without any blurring. Focus the nearest part of the miniature and use a high f-stop. That way you should get a sharp result for the whole object.

        2. Great article! Thanks for all the effort of putting this together. Quick question- do you think it would be possible to 3d print the miniatures with decent results?

      2. Great article! Thanks for all the effort of putting this together. Quick question- do you think it would be possible to 3d print the miniatures with decent results?

        1. It might work for some simpler items. But the scan does not produce a mesh with straight edges, everything looks a bit wobbly and melted. Fine details are almost completely missing. Would be hard to paint this. I think, the good final result is only possible because of the texture.

  1. I’ve had the sparse cloud form at a weird angle that then leads to scaling issues when trying to import into Blender. Other models will come in right side up and at the proper scale. Do you know how make adjustments so the sparse cloud is set properly?

    1. You mean the whole model has another scale when imported in blender, or only parts of it? Should be no problem to rotate or scale the model inside blender. Use the base as a scale. You will always need to alter the scanned results a bit to match with your other models.

    1. As far as i know, there is no version of 3DF Zephyr for Mac OS available. I’m sure there are similar programs for the Mac, but I’m not familiar with them.

  2. 3DF Zephry has been updated. There are new settings and some settings have been removed.

    Tie-points quality is a new setting added to the project wizard settings
    Discredization is a new setting in Mesh creation.

    Edge filter was added and High frequency gain was removed. Are these two the same thing?

    It seems like the 3D images generated used from before the last time I used Zephry come out differently now. How do you have things set now with all these new settings changes?

    1. I scanned a bunch of 6mm miniatures recently and am quite pleased with the results. So i really like the updated version 🙂 . As for the new UI options, i personally left them mostly untouched, just used my settings from the tutorial with minor changes and got a very decent result.
      Changes i made were:
      – Sequential instead of Approximate Photo Ordering
      – a high Image resolution (100%) in the Mesh creation phase along with higher setting for Edge filter (0.5) and Enhance filter (0.25) And yes i think Edge filter replaces somehow the high frequency gain.

      I always leave Tie-points at the default „medium“ setting, same goes for the Discretization Factor, because i never had performance issue and am quite satisfied with the detail of the mesh. Be sure to use the retopology filter in the final mesh, as it evens out the edges length and optimizes the mesh after cutting away unwanted geometry like the floor.
      I never really looked into it before, but the built-in documentation is actually pretty good in explaining all the new features. You can open by clicking the question mark in the top menu bar.

  3. Hey,
    Really appreciate your article on scanning for TTS.
    Was hoping to download the circle templates, but they don’t appear to be downloading at the moment.
    Any help would be great.

  4. Hey man, I’ve been having a really hard time scanning in some models, and I have followed all of the instructions you have laid out. Think you could hit me up with some pointers on taking photographs? I can also send a zip file of the photos I have taken so far for reference. Thanks!

  5. I would recommend to print it on glossy paper, or paint it with gloss varnish (i used the latter one) to achieve less light scattering on the surface and a good black color

    really not a flat matte varnish ?

    1. In general, the background is not the decisive factor, the scan will work on almost all textured surfaces. But glossy background doesn’t catch the lighting as much, thus it stays dark and provides a better contrast to the colored figure. This allows Zephyr to better capture the figure. A matte varnish diffuses the light and brightens the surface. But it’s best to try it out and see what works best for your setup and the things you want to scan.
      Of course, the most important thing is a good focus.
