Importing meshes with base color materials? (not textures) (not baking)

[Vaelsty]

I searched everywhere on devforum, youtube, reddit, etc. None of the solutions worked for me, I have hundreds of meshes (extremely low poly, 5k triangles per 150 objects) so I cannot bake each color separately and apply it manually in roblox studio, it would take days. FBX and OBJ have color data that I believe roblox studio can read, but I don’t know how.

I’ve imported in the import mesh button, in the asset manager (both insert and insert with location), and in the mesh parts’ choose file button, with FBX, OBJ, and GLB, but none worked.

The only answer I found that wasn’t about baking textures was this one:

How do i import meshes/models with colors and textures from blender to roblox?

you can try with export in fbx. Im doing it when i exporting UGC to roblox studio. Select Path mode to “Copy” and click on a gray box on right. Then when you export model textures will add instantly when importing to roblox studio.

I followed all the steps, but when importing to roblox studio all meshes were grey.

Am I missing something?
