There's a blender addon called gret (github.com/greisane/gret), and it has a lot of great features. 5.0 broke some, and greisane's been inactive for a while.

So, I've made a fork that fixes some issues for Blender 5: gitlab.com/Rikketh/gret

LMK if something else's broken, or make PRs with fixes.

MSAA is great, but edge extrapolation can get really ugly in VR, ironically by introducing aliasing.

Switching to centroid-sampled normal interpolator for areas with large enough error seems to be a good enough fix, though. Same works with texcoord1 & texcoord2, not affecting authored UVs visibly.

The best way to implement fallback shaders in VRChat.

Since it's driven by a texture over texcoord0 one can swap it for solid pink to give someone a heart attack.

New eye shader is done, finally. Audiolink wasn't planned, but it's kinda neat. Might be worth linking pupil dilation to chronotensity.

A really funny idea is to link veins intensity to SteamVR's session duration.

Unity fuckup of the night:

When generating tangent space in fragment shader, manually scale converted coordinates by unity_ObjectToWorld's lengths, as interpolators only scale once--through NDC stage. This also takes care of tangent view direction for parallax occlusion.

@hecka.space here's a functional solution I promised yesterday: youtu.be/haU0YtXSCic

Can't escape aim constraints, unfortunately, but it does the trick well, and allows you to adjust where the constraint flips.
