Vertex color support?

[emannotava]

So this isn't really much of an issue but more so a feature request that would be highly appreciated
I have a bunch of FBX here that are known to use vertex colors for actually texturing the model, it's weird but that's how these models are made.
Do you think it would be possible for the render to check for vertex color data and if found, use it in the render?

Late reply but, in my case exporting models with vertex colors to .glb files cause the my explorer to crash on windows 11 whenever a thumbnail is being generated for the model.

I made a quick script to remove them in blender if that you (or others) should be able to use to fix the thumbnails if its vertex colors are not something that is needed.

import bpy

def reset_mesh_object(obj):
    # Ensure the object is a mesh
    if obj.type == 'MESH':
        
        # Clear vertex colors
        while obj.data.vertex_colors:
            obj.data.vertex_colors.remove(obj.data.vertex_colors[0])
         
        
        print(f"Vertex color for {obj.name}")

# Process only the selected objects
for selected_obj in bpy.context.selected_objects:
    reset_mesh_object(selected_obj)

print("Selected objects have been reset.")

Well in my case I'm dealing with FBX files that literally don't use any textures at all, but instead are colored solely using vertex colors, which is stupid but that's how the FBX's in question are made up

I'm also still on Win10 at the moment

There's nothing wrong with relying solely on vertex colours. Lots of valid reasons to do that and it should be supported across all formats.
