Hello! When working with a rather large scene created in 3ds Max, I encountered several problems.
After the first import via datasmith plugin (with standard Physical Materials combined into Multi/Sub-Object materials), with keep ierarchy enabled, after applying the materials in TM, I save the project.
If I make some changes to the datasmith file, and update it in TM (not via direct-link, but via the “update” icon in the import panel), all materials are updated to those in the file.
Also, sometimes objects that are exactly in the scene from which the export to datasmith was made disappear.
If the datasmith file has been renamed or moved, when the path to the file is restored, the materials and objects disappear again.
I have asked GPT what the problem might be, but his advice didn’t help me 
Please help!
Thank you!
