I'm using blender 2.82 and the rigify add on. I tried to do a dragon rig and even though its not perfect it works for now. At least in blender... when i try to export it the spine causes some weird twitching. i already read tons of threads but no solution worked for me. like the gamefriendl script by paolo https://developer.blender.org/p/pkrime/ or the shear patch i alredy checked for non uniform scales but havent found any (in the fbx there are some but even putting everything back to 1 doesnt help...) the only thing that kind of worked was usind the origional bones instead of the def bones, but hat causes new problems.
does anyone have an idea what im missing here?
