Standard JCMs don't work when IK on import is activated

[Mike]

Hello, since the last commit the imported standard corrective morphs look really off on multiple parts of the body, when posed:

‌

Edit:

I’ve done some testing and it seems like this problem only occours, when IK on import is activated.

Yes, and some of the face units are a bit off too , like closing the eyes. This IK simple rig is a pain to deal with

I see, when I test scene with recent version, I did not use the new IK rig for import optionso I can not see the issue.

(Btw I like new IK rig. good work, it seems offer new interesting option, though default rig should be complex than before. )

The problem is not IK per se, but rather that the bones in the IK chain may be connected to their parents, to prevent that the bones fly apart when loading extreme poses. However, connecting the chains means that the bones are moved slightly, and apparently that does not play well with JCMs.

Fixed by disabling Connect IK Chains by default. The option may be removed entirely later on. Also, the rig now starts in FK mode, so going to IK becomes an active choice.

I think this issue can be closed. Bones are not moved on import anymore, but you have to use a separate button on your own risk
