View Full Version : Help! my UV map is moving!

I really need help! I've never encountered this problem before. A client sent me a model to map & texture, and I'm finished with it. Then I went to test animate it. When I move the model, all the textures slide and shift, as I'm moving it. When I opened the UV texture editor, I could watch the UV map warp, twist and finally explode into a jumble of white lines, as I rotated the model. If I rotate it back to it's original position, the UV map shifts interactively back to it's original position as well. Can anyone tell me what's happening and how I can fix it?

...a little later after messing with this problem, I've figured out that it has something to do with the "automatic UV mapping" feature. There are a few pieces to this model that were mapped separately using a planar or cylindrical projection (rather than the "automatic mapping"), and those pieces aren't having this problem. So I went back and tried re-mapping one of the troubled sections with a planar projection instead of automatic mapping and the problem is gone. Is there any way I can fix this without remapping the whole thing?

I'm working in Maya 7.0 for Mac, if that matters.

Update:
It's definitely something to do with automatic mapping, I tried creating a brand new simple Poly sphere (in a completely new file), and when I mapped the UVs using "Automatic Mapping" I have the same problem!?
I've tried resetting the default settings for the automatic mapping feature to no avail.
It may be that this is some issue with my system and Maya 7.0.
I was trying to remember, but I don't think I've used auto mapping, since I upgraded to 7.0 (though I used it quite often in 6.0 without any problems)

Found the answer, thanks to an earlier post by rhassan back in November! Simply deleting the history after auto mapping fixes it. What I don't understand is why you have to do this in Maya 7, I never did it with Maya 6 and had no problems? anyway I hope this helps someone else.
