Having issues with Dataprep where after replacing materials in my Datasmith scene with a “Substitute Material By Table” node, materials look ok in the Dataprep editor but look completely different after committing.

Materials as seen inside of Dataprep editor after execution, before commit:

Materials as seen on asset after commit:

Model exported from 3DS Max 2024. Using Unreal Engine 5.3. (Other objects in the scene have been hidden, other objects are not having issues with materials.)

Anyone know what might be going on here? I’ve been importing content from Max with datasmith/dataprep for a while and this is the first time I’ve encountered an issue like this. I’ve verified that material setup in Max is done properly. Materials are getting replaced properly with the proper materials in Dataprep as far as I can tell.
