Maya muscle not constraining muscles to joints when mirroring?

Anonymous — Mon, 01 May 2017 03:24:03 GMT

So after finalizing a muscle which mirrors it to the other side, when I rotate the associated joint the side I was originally working from is constrained properly but the mirrored side's insertion-sided controls rotate freely like it isn't constrained to anything. What could be the problem?

EDIT: Also I should mention that the mirrored muscles come out black, I'm not sure if that's indicative of any problems but just putting it out there.

After having the same exact issue for a while. I just realized the fix for the mirroring muscles issue. Hopefully this answer helps others in the future since I couldn't find anything on it either (even in Maya documentations).

The fix:

When putting in your replace terms for left ("_L") or right ("_R"), Maya also needs to detect your joint names. So, if your joints are named "Left_Shoulder_jnt" and you name your muscles, "L_Bicep_musc" and try to replace "L_" with "R_", Maya WILL NOT mirror properly and the muscle flies off. However, if you named your muscle "Left_Bicep_musc" and try to replace "Left_" with "Right_", maya will mirror properly!

TLDR; -Make sure your joint side identifiers and muscle side identifiers are the same (Ex. "Left_Shoulder_jnt", "Left_Bicep_musc")

Hope this helps!
