After I rebuild my pose editor shapes look different

I have a delta mush and there is no problem when I delete it. But is not an option to delete, I need it otherwise I need to do many more poses

That should be a simple fix - just add the deltamush’s envelope attribute as 0.0 into the dResetAttr dict. You can open that dResetAttr with the JSON Editor for doing that.

This way it will always get turned off for any pose editor things.

Also when he’s running the poseEditorApply() function, he’ll switch that attribute to what you define (0.0 in that case), and then switches it back again.
