Correct Export Settings from Vstitcher to Keyshot

Help and Troubleshooting
1

I am trying to figure out the correct export and import settings for product from Vstitcher 2023.1.2 to Keyshot 2023. All of my black materials absorb all light in Keyshot and it makes rendering look strange.

Hi Nora,

Iā€™m not a Vstitcher user but if I look at their online manual I would try to export as Autodesk FBX with separated textures. You could also try GLTF which has the textures included in the file, that can be handy but might give you less flexibility.

The type of material in KeyShot is important. I guess they are imported as ā€˜diffuseā€™ which basically is just a color without any further properties. So you should change it to a material which has some properties like roughness/bump etc. Plastic is used a lot so that might be a good start.

It will be a matter of testing and once you have found a nice way about what you need to change after the import you could automate the process by a python script. Not sure if itā€™s worth doing because I think the amount of different materials is not that high.

If there would be a plugin between VStitcher and KeyShot it could do all for you but I donā€™t think there is any. Without a plugin you always need to adjust the materials for the renderer but maybe a GLTF gives a satisfied result already. The FBX and OBJ formats commonly used to export things to other programs but might need some tweaking.

Oscar is correct. The USDZ format will also contain the UVs and textures. However, importing into KeyShot you will notice GLB, USDZ, and FBX files import as a ā€œGenericā€ material each with its own unique material settings. While not always perfect (no universal 3D file really is), the USD material should be the closest representation of the material as it appeared in the native 3D modeling software.

I didnā€™t see USD in the export settings of VStitcher but am I correct that it will be, or is going to be, the ā€˜newā€™ FBX. So lot of (upcoming) support but with more capabilities/properties within the file format?

Thanks for pointing that out! Honestly, Iā€™ve never used VStitcher. So you made me actually look up the support which I should have done in the first place. I did notice that the FBX exporter supports PBR materials which is great because Keyshot Generic Material will support the PBR materials. IntroductionPBR.pdf (browzwear-global.com)

Yes USD/USDZ is the new FBX.
