A shader for Optifine & Iris that aims to providing realistic visuals with very minimal performance loss. Almost every effect/feature can be fine-tuned for the ideal balance between performance and quality. This project is still a very early work-in-progress, there is much work to be done.

Resource Packs

Supports LabPBR and OldPBR texture formats; The default setting for materials is "vanilla", which hard-codes a limited set of PBR material values for the original Minecraft textures.

The recommended resource pack is Patrix; when used make sure to set the shader setting for Material Format to "Patrix", as it uses a special combination of OldPBR and LabPBR formats.
