If I learn VRChat implementation in the future, I'll retroactively update some of my models to have an alternate version with the VRChat rig. But right now I don't have plans for it yet, especially given that the models aren't optimized for VR either.
Understood! If such an update comes out, be it made by you when you learn to rig for VRChat, or made by someone else, should you outsource that rigging to be done, I very much look forward to it! I'd love to wear and show off this model, it looks fantastic, and even though my current Angel avi is pretty accurate looking, your angel model's show accurate look is so much better.
