This mod requires MixinBootstrap (curseforge, modrinth) to run!
Mixin 0.7-0.8 Compatibility (curseforge, modrinth) might be helpful when another mod uses an older mixin version and you are thus unable to launch the game.

RenderLib is a client-side only mod that makes necessary changes to entity and tile entity rendering for some of my other mods. This mod on its own does not provide any meaningful improvements regarding performance and you probably only want to install it when using a mod that has this mod as a dependency.
