I have an object with multiple identical meshes that I would like to use the same texture space for. When I unwrap the object, however, it maps each of them to a separate space. Is there a way to tell Blender to map them on top of each other, instead of having to manually move each one to the same space?
If the vertex orders aren't screwy, you can
- In Edit Mode, P separate the identical components into their own objects
- UV unwrap one of them
- Back in Object Mode, with all component-objects selected and the unwrapped one active, CtrlL > 'Transfer UV Maps'
- CtrlJ rejoin the components into one object.
