[1.20.1] Lamp block halos not working on 1.20.1

[guilomet]

Minecraft version

1.20.x

CodeChickenLib version

4.4.0.512

CBMultipart version

3.3.0.146

ProjectRed version

4.19.0-beta+3

What happened?

When I use the colored block (inversed or not), I don't have any colored light, but only a standard light (like a torch) with some strange shaders popping sometime.

Here some screenshots (no more mods are in this instance, only the dependecies and Project Red).

How do you make it happen again?

Just place some illuminated and colored block anywhere.

Confirmed bug with non-fabulous rendering mode. Will look into it

This is a bug in NeoForge. It was fixed in the 1.20.x branch but has not been picked into 1.20.1. I'll see if I can open a Pull Request for it.

neoforged/NeoForge#231

Arf, I got the bug with Forge to, and indeed Neoforged didn't backport some fixes. But I got this problem in Forge 47.3.1.
Just to know, have you some futur compat with Oculus shaders or not ?

[MrTJP]

Trying to throw together a mixin to path the bug at runtime.

There's no specific compatibility with Oculus shaders or any thing else. It might work though.
