Oh?, if you need to contact me directly i can give a test version personally i am RevyTea on discord
Works fine on my end with fbt but could differ on setups. Ill think about making a world with test avatars sometime, i know with making digitigrade rigs can make it harder with feet with ik tracking and have made many workarounds to make it look good. ill be even testing a new rig system on my next model with digitigrade feet to see if i can perfect it
