I just wanted to add that we’re working on better deformation support. And the ML Deformer can also be used on models outside of Maya. However, the plugin to generate training data is Maya only. But you can easily write your own script to generate training data in other apps. You have to just export it to Fbx. Also the abc file can come from other packages as well.
What the Maya plugin does is generate random values for given controls, such as the rotation x y z values of bones. It does this within given rotation limits.
