This, I think, is the most needed update. You can't do anything with Valve's AnimGraph in it's current state. 1D Blend cycles sync is broken, 2D Blend only takes sequences as inputs, motion matching not working, constant crashes. Only type of locomotion you can make right now is directional, but barely working.
But there should be no internal code in the new version. Coded fully using sbox's API, similar to ShaderGraph and ActionGraph, so it can be extended or modified, like adding new node types for example.
AnimGraph is the only thing stopping me from fully switching from Unreal Engine to sbox. I wish I could spend more time making full scale projects, but you can't really do much without proper character animation tools.
Right now I have to work on my awful version of custom AnimGraph editor, instead of making games.
