Indded :-) Thank you for the exhaustive reply. Knowing houdini well too it seems to awkward to not be able to copy some polygons and uv's from one object to another. I've now taken the hard edges out of the equation by disconnecting them. But is "Copy Texture Projection from Source" fundamentally broken or am I doing something wrong?
