PBR Support / Optifine Parity

[dbrighthd]

Hello! I am very glad that there is a fork for Animatica for newer versions, thank you for taking the time to develop it!

I was wondering if the scope of this project will be to just port Animatica over to newer versions, or if it also seeks to fix Optifine parity issues that Animatica had such as this:
FoundationGames#57

[coredex-source]

I'll definitely look into it!
