Believe me, you don’t want realistic feet at the point you have single toe control.
Its another additional 20 bones that are mostly useless - literally had to do this for a client not too long ago: it was pretty painful.
Whats worse is you can barely notice the toes moving in the final animations… felt like wasted time for the most part.
That said, control rig is getting kinda nifty. Considering baking animations is all that the engine is good for right now thats a good thing
