There appears to be a symmetry bug for large scale models. I'm using a normal low poly model that's ~130 cm in height. Unfortunately, I'm unable to set symmetry tolerance beyond 1 and therefore can't get the symmetry feature to lock in. If I scale the model down, then I can find an acceptable point tolerance to get symmetry to stick, but that's not really a feasible solution as I'd prefer not to re-scale models once real world size has been set. Any solutions would be welcome. Thanks!
Thanks for your quick response! I spent a bit more time troubleshooting tonight, and I think my initial diagnosis was actually incorrect. It looks like the problem isn't scale at all. It's due to the fact that I don't have perfect symmetry in my model. Although it looks symmetrical, I've got higher subdivs in zbrush and the details in those high subdivs create a slight asymmetry in the lowest subdiv level. I've sent you the obj if you'd like to take a look.
I think the current workaround is to just re-mirror my character's lowest subdiv levels before I import to Unfold3D.
For future Unfold3D releases, if a manual symmetry setup option or more flexible symmetry functionality that allows for imperfect models is introduced, that would be fantastic. Thanks!
