System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 531.41

Blender Version
Broken: version: 3.5.0, branch: blender-v3.5-release, commit date: 2023-03-29 02:56, hash: 1be25cfff18b
Worked: (newest version of Blender that worked as expected)

Short description of error
Blender 3.5 fails to export materials on GN objects

Exact steps for others to reproduce the error

  1. Open the attached .blend file
  2. Select ExportCubes object and export it in the FBX/gltf file format
  3. Import the ExportCubes FBX/gltf back into Blender
    Result: Assigned materials are missing and the imported object has no material slots
    Expected: The imported object contains the material slots which were supposed to be exported.

I think I can see the problem. The Geometry Nodes modifier entirely replaces the materials of the Mesh/Object, but the materials of the original Object are what are used in the export.

@Rawalanche To work around this issue, you can manually add the correct materials to the GN Object prior to exporting.

So far this issue appears to happen with most of the export formats except .obj

Infact, there was already a TODO task for this actually, see #96721.
