[Bug / 1.20.1 / Forge] Alex's Cave's VFX invisible bug

[VanilaBOI]

The Alex's Cave's mod adds it's own shader like effects, for example when a mob is irradiated they glow green but when the paperdoll is active the mob is invisible (with the exception of some angles where they do show for some reason). This happens with other mobs as well that use the same shader like engine (for example the notor when you look right at him). It's also worth pointing out that if the player is irradiated, all mobs are invisible (except some angles).

If it's of any use, I could upload a video showing of the mixin.

I am aware that this could be a problem on alex's end.
