Hi, I am afraid the spine “Squash and Stretch Profile” does not export to the guideTemplate, or it does not import from it.
My Squash and Stretch Profile animation curves have non-default values, see the picture. But after exporting the guideTemplate (and importing the template back to my scene) the profile has default values again.
I`m using mGear 4.0.9 with Maya 2020.
