When I imported my mesh from Blender, I used the default mesh import options, which also enabled Vertex Colors on my mesh, which I was using for Substance specifically. In Roblox Studio, everything appeared fine, the textures appeared normally, (as seen on right side of image) however, after uploading the item to the catalog, the vertex colors have appeared to magically return, leaving me with a broken catalog item.
I’m unsure what exactly to do, if I need to update my catalog item, or if this is a bug. I’m not even sure how to update a catalog item, since it doesn’t have the ‘update existing item’ like Models do.
