3dsmax 2015 provides some python support, not sure it would be that great judging by other aspects of that program.
But nonetheless they could at the very least provide some basic standartized setups, rigs, etc, so user could just skin and animate from the get go.
Cat and biped are very clumsy and buggy, and typically you want hand made rig with your own scripted controllers so you can actually fix anything
that goes wrong.
I would love to see any movement into 3ds direction from Epic, at least those standard setups i suggest.
