I have this model of parts and i know how to turn it into a mesh, but i want the mesh to have the same colors of the parts in the same locations, is it possible?
You could try to make a texture, and use that. If you get it right, it would look good.
You can make a texture by unwrapping all the UVs in blender and color them or you can bake whatever you want as a custom material and apply it in roblox or you can make them separate meshes based on what color they’re gonna be and you can color them in roblox.
