Hey.
Is that image actually from the joint mover? Nothing I see has the bottom example as the default. I’m assuming this is just an extreme to illustrate the point?
I could probably write a script to fix this, but I don’t have the time to test (3 projects + new tools = no time).
Basically, you just want to zero the mover groups, though not all. I’m assuming the example would be more like a finger? And you want the child movers to be perfectly in line?
If so, you just need to open the jointmover file (under MayaTools/ART/) and select the mover groups (1 step up from the mover) and zero out the translate Y, Z and rotates. Same for spine if that’s what you’re looking for. (the proxy geo will look off, but the bones will be correct).
Here’s a file where I did a pass on that. See if that addresses your issues and causes any problems. You’ll want to overwrite the existing file under MayaTools/ART/
