"Source 2's animation system is similar in many ways to Source 1. As in the previous screenshot, the model worked just fine in the editor, though once in-game it broke. The final result is still the target skeleton minus the base skeleton, though instead of being overlayed as a delta animation, it's ran through the animgraph.

It didn't work when I first tried and was broken for a week or two before suddenly working. I'm not sure if I accidentally fixed something or if an update to the game fixed it, but it works now if nothing else. Everything else slowly started to fall into place and kind of snowballed into a working concept.

I then did a light rebuild from the ground up, moving everything into an isolated addon since I'd created way too many test models for separate concepts. Everything is merged and /kind of/ works (ie jigglebones, physics, etc) but most of everything is going to need to be tweaked quite a bit with a few things probably built or rebuilt.

The model still doesn't sit on the ground fully with IK chains being off quite a bit. The IK chains issue extends to the hands as well with the arms crossing over each other in the pistol animations. The weapon for holding bones needs to be moved as well.

TLDR Quite a bit still has to be done but I'd consider this a big breakthrough in my own learning."
