No joints created

Hello, I’ve used mGear before in Maya 2020 and it worked perfectly but now I changed to 2019, I installed 3.3
and then today upgraded to mGear 3.4 and there seems to be no joints created after I build from selection. None of the controls relate to each other (for example rotating spine controls only moves those, not the arms, head etc)

I’ve tried deleting every file related to mGear and reinstalling but there’s no difference, I get these messages after the build selection is finished.

Hopefully it’s an easy fix or error on my part, I appreciate any replies.

Thanks

can you share the guide?

Hello Miquel, my apologies about not formatting the code.

I just used the sample biped template, no changes made to it. I tested the quad template and it works fine so I’m guessing something has gone wrong with the biped template.

I noticed this too if it helps -

now that I realized this issue is not new :stuck_out_tongue:

the issue still open https://github.com/mgear-dev/shifter_classic_components/issues/12

@Zola found this solution:

I have found that by setting an optionVar (related to pairBlend creation on constrained transform attributes) solves the problem:

pm.optionVar(iv=(‘animBlendingOpt’, 1))

The related Preference setting is the Animation Blending. My Preferences was a bit trashed and no option was selected there. The Never blend… option (animBlendingOpt=0) prevents transforming constrained nodes and prevents setting its constrained parameters as the leg building code probably tries.

Also an alternative brute force solution: Error after build

Thanks, I tried commenting out the code but it didn’t work but simply deleting my Maya user prefs worked, thank you!
