Is XSFur shader acceptable to use on avatars? I used it for parts of one outfit but ended up never wearing it because I was worried about performance impact.

1. Chaos theory is on unreal engine 2, should be able to rip the models fairly easily. And they look like they come standard with bones set up. Look around game folder and google how to extract models.
2. Get them to .fbx format somehow, the tool you used for ripping might already be able to save it to such format. If not, you can open it in blender, click giant "fix model" button in CATS plugin and then export as .fbx
3. You put it in unity and do regular avatar work. You can find tons of tutorials for the last part. It's mostly just putting the model into scene, adding VRC avatar descriptor component and filling it out with at least lipsync settings.
Once that's done you upload the avatar and it should more or less work.
