HighPoly Model Export for baking missing vertex colors?

I’m encountering a strange issue with exporting a high-poly model to an external baker. The programs in my pipeline are RC → Substance Designer.

Substance Designer gives me an error message that the exported model as FBX (2020) doesn’t have vertex color information. This shouldn’t be the case, as I “colored” it in RC before exporting it as an FBX. I used the default export settings, with Vertex Colors and Vertex Normals turned on. Interestingly, in Blender, vertex color information doesn’t show up initially either. I have to activate it via Shading → Color Attribute.

When I export the model through Blender, the baker does find the vertex color data and can bake normally.

This isn’t exactly an ideal workflow, right? Currently, the workflow is RC → Export → Blender → Vertex Color correction → Export → Substance Designer → Baking.

It’s possible I may have missed a setting in RC, but after troubleshooting, I believe everything is set up correctly. Where could the problem be?

Hello @OlPainless_1x01
What were your exact settings in RealityCapture? have you tried just colouring of your model or also texturing? I was trying this but I didn’t get such error.
