Hello, I have a character which is rigged and is working, but when I move the Primary Null up more than 10 units in Y space, the rig has an error on the arms and they collapse down. I have tried recaching and cannot determine what is causing the problem.

This is very frustrating to have spent quite a long time adjusting the weight painting on this character to have this problem. If you could point out what is causing this please let me know. I tried putting the character into a subnet but the problem occurs there as well.

I have included a link to he scene and mesh below.

Hi,

maybe I am missing what you mean by “moving the primary null” (I used the “master_ctrl”), to me, moving the rig up is looking fine:

Thank you malbrecht, yes I meant the master ctl node. I am still getting pinching deformation at the elbows when I reposition in Y-space (positive or neagtive) using the master ctl node. I'm not sure how the bug is not recreating on your end, I will try merging into a fresh project and see if that corrects the error.

Ah, I see what you mean - when you wrote that “the arms collapse”, I really only looked at “the arms”, not at the elbows

The problem seems to be somewhere in the “arms noodle” setup, I assume there is a rotation or maybe a scale messed up. As soon as I have a free system available, I'll try to figure it out …

I exported the AutorigsSettings from your Rig and built a new rig, but I can't reproduce the errors you're reporting…

if you're able to track down what has caused this please let us know with a bug report.

thanks
