Brilliant, I really appreciate that, it’s working now. It would be great if there was some way of debugging this myself though. I think the problem was caused by importing .stp files with Power Trans to Maya, I stripped out all the extra nodes it created but looks like it made a hidden mess of the UV’s.
I like the Puzzles visual programming idea, reminds me of using Demicron Wirefusion (i’ve got a pro licence going cheap, )
