Well I'm already using my own file format to store just a cloud of UV points - all that my scripts allowed to change.

This morning is my kid's last half-day at school - he breaks up for the summer after lunch. I've already looked around for the original script and can't find it but if the phones stay quiet I'll se if I can do something about recreating it and moving towards making something that might be actually useful.

Cheers,

Cliff
