Another problem, and this one has me tearing my hair out in frustration. Say I have an imported model with two material zones on the one mesh. I am now texturing it in Vue. I go to some length in texturing the first material zone; now I want to have, say, a slightly shinier version on the second. The obvious procedure would be to copy the material from zone 1 to zone 2, and then edit zone 2. But as soon as I try to do this, Vue detects that it has two the same and deletes one of them! I've tried saving the material and loading it into the second zone, but the same thing happens. It's maddening! How can I edit a copy of a material? Ah, I've found a sort of fix, which is to create a dummy object, copy the material to that, edit it there, and drag it back to zone 2 and then delete the dummy object. This changes the name of zone 2 to that of zone 1 (!) and seems a very laborious way of doing something. There must be an easier way?
