Bug - MIRROR SKIN changes weights on other mirrored skinning

PostPosted by DominikUrban » Thu Feb 02, 2017 5:36 pm

Hi & bonjour Akeytsu! :)
Thank you for your work, I am very grateful for your software, I find it really useful and great to work with it, I am sincerely happy I found that it exists.

BUG: I found a post "akeytsu (Pre Release) Beta KNOWN ISSUES" where you say: Mirroring keys - There are several options in akeytsu that automatically mirror keys, based on naming rules that identify left and right controllers. As of now, any controller that isn’t identified as a left controller or a right controller is automatically deemed a central one. This raises unexpected results when trying to mirror a non-central, non-symmetric controller.

However I am experiencing a problem similar to this but different with a Mirror Skin bug: when I already have a facial rig done with all the joints created on both Left and Right sides, and I want to mirror already existing joint to overwrite it, e.g I have both Ear_L and Ear_R and make a change in Ear_L and want to mirror it also to Ear_R so they are the same, and when I click Mirror Skin the bug happens: it creates weight changes on other already existing joints (that aren't connected to the Ear and I didn't have them selected).

Enchanté (je parle aussi francais, si vous preferez :) )

Hi DominikUrban,

We are working on your problem.
There are two points you have to know about Mirror Skin.

Image

First, even if you just select the joint "FCL_Ear_L" before clicking on Mirror Skin, all the vertices will be mirrored.
To mirror only one part of your head, you have to select the vertices you want to mirror.

Then, it seems that the weird results you obtained after mirroring, on the tongue (and in some other places), came from vertices of different meshes (dasenD and jazyk for the tongue) which are too close in Bind Pose:

Image

So vertices from the tongue have weights' copies of vertices of the teeth, that's why we see the end of the tongue fused with the gum (and some others weights copies issues) after mirroring:

Image

We are working on a fix for this issue.

Thank you for your useful request which allowed us to find this issue!

Regards,
Cassandra
