I’m starting to transition over to artv2 as well. It has the occasional script error but seems to be working pretty well so far after I fix the errors manually. If I can, I will transition over to V2 even though this is technically beta. It seems to work better than V1 so far. In V1 it’s almost impossible to do anything related to creating new rigs. V2 also works with maya default Y up which I prefer. Maya doesn’t actually handle Z up as well as it should.
As an update, I got some pretty good results with ART V2 but the IK legs don’t work right. The knee twist behaves unpredictably and also the foot randomly twists itself while the ball stays in the right spot. In FK it’s fine.
I was able to hack around the occasional syntax error but this is a fundamental issue that I’m not sure I can fix myself. In fact I’d prefer IK legs that use a pole vector aimer anyway like the arms do.
