i built a model in roblox studio and want to turn it into a mesh instead of a union, but when i turn it into a mesh and load it back into studio,it does not have color anymore, is there a way i can do this?
Do you want it one colour, or different colours?
If it’s a MeshPart and you want to ‘paint’ it you need to look up how to ‘bake’ the texture. Posts like How to import models from blender with textures without baking? should help.
You probably should try the Search tool up top!
OP didn’t mention blender, I think they may be doing this with only studio by exporting to obj then importing that to a meshpart. If you do that method, you can only select a single material and a single color for the resulting mesh.
