Advanced Member Gary Dave Posted June 13, 2018 Advanced Member Report Share Posted June 13, 2018 Been getting this a lot lately, and it's really starting to affect my daily work schedule. I know we have issues with baking when more than one symmetry is active, but I've been getting all sorts of weird UV issues before the baking, I've commonly used symmetry to quickly copy over my mirrored UV's, but now all it's causing me is grief. See video here:https://www.dropbox.com/s/gi2dxbd8nzo9ph9/MirrorUVBug.mp4?dl=0 I've had it much worse than this in the past as well, see the 9:58 area on this video for another example: Using the Steam version by the way, 4.8.15 I believe.

Carlosan Posted June 13, 2018 Report Share Posted June 13, 2018 I see you enabled symmetry on X-Y axis Are the seams symmetric on X-Y axis too ? Quote Link to comment Share on other sites More sharing options...
Advanced Member Gary Dave Posted June 13, 2018 Author Advanced Member Report Share Posted June 13, 2018 On the youtube video? Yeah, the whole thing is Z and X symmetrical. If you see the bit before the time I pasted in, the UV's are copy/pasted manually to avoid this bug. If the mesh and/or seams weren't symmetrical, then the copy/paste wouldn't work either, but it does. The dropbox video I pasted in my first post is even simpler, just one axis of symmetry on a basic mesh but it still messes up my UV's when I perform a symmetry copy.https://www.dropbox.com/s/gi2dxbd8nzo9ph9/MirrorUVBug.mp4?dl=0 Very occasionally, maybe once out of 10, it will work fine.

Advanced Member Gary Dave Posted June 14, 2018 Author Advanced Member Report Share Posted June 14, 2018 Same issue unfortunately. It could be due to the mesh. I'm having a hard time pin-pointing the problem. I imported the basic chair model as seen in the dropbox video, I cleared my seams and gave it an unwrap (symmetrically). The sym-copy worked fine for mirroring the UV's. Then I brought in that cupcake model, cleared seams, used symmetry to triple-check that the mesh is symmetrical, did my seams. But, regardless of if I use X/Z symmetry on their own or X and Z together, 3dc seems to just cancel out some of my seams in random spots. And I do mean random, it's never the same result each time I try it. Example:https://www.dropbox.com/s/x8nplu6rmupgeg6/SeamsIssue.png?dl=0 I've really got to get back to work now, but when I get a moment spare I'll test it a bit more on some other newly created geometry. in the meantime, if anyone wanted to see for themselves, here's my 3d coat file:https://www.dropbox.com/s/e090dqn6p2at3yh/CupCakeUVIssues.3b?dl=0 (<300kb) Quote Link to comment Share on other sites More sharing options...
Carlosan Posted June 14, 2018 Report Share Posted June 14, 2018 Thx Gary. I did some tests on my side and got your same wrong results. I reported this problem as bug. 2 Quote Link to comment Share on other sites More sharing options...
