More shading models about bsf HOT 3 OPEN

As for hair, maybe it worth to look at how Confetti integrated TressFX into the Forge recently. It seems quite performant and portable.

No promises, but I'm looking into implementing Separable Subsurface Scattering myself so I can get a nice skin shader working. Relevant readings in the following links:

A good TL;DR video discussing the paper on SSSS, perhaps:

This one is long (100+ pages):

Feel free to holler at me in the Discord about it. Getting a glTF 2.0 loader, pathfinding, & Android port going are going to be a bit higher priority for me, but I think implementing SSSS could be some good low-hanging fruit compared with integrating EnTT & Bullet3 into the framework (as plugins or otherwise).

Small tangent: I feel that this project is unusually high-quality & well-documented. I have technical reasons for choosing to use this framework over full engines like Godot, Unity, or Unreal, but the extensive documentation & support work is a very very welcome cherry on top. A small subset of the core tech I'm developing is domain-specific & so won't be contributed to this framework, but I would like to contribute whatever work I can to benefit this project. Feels like the thing to do. Thank you for your hard work on all of this.

I'll see about posting in the relevant issues pages for other tasks & pinging you on the Discord server when I find the time.

Sounds good, thank you. This would be very welcome.
