Some of my meshes are not showing their textures when importing from 3ds max to Unreal (Datasmith)

Hi!

I’ve used Datasmith to import my archviz interior scene from 3ds max. Some of my meshes are not showing their textures, only the grey checker material.

Any ideas?

What types of materials are they? They may not be supported by the conversion tools

There are some subsurface scattering on the meshes that are missing textures. I recently tried to export a mesh one more time and it told me just whay you said that the material is not supported. I missed that error message before.
