Arc

A shader for Iris & Optifine 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 in beta but will be reaching initial release very soon!  

Features

- HDR - Full PBR support - Dynamic, direct, colored block lighting - Volumetric fog/lighting - Automatic exposure - Screen-space reflections - Water waves & refraction - Supports distorted and cascaded shadow mapping. - Depth-of-Field - Bloom

Also contains special support for PhysicsMod ocean waves & snow!

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.

Compatibility & Support

For best results use Iris 1.6 or later; however most features should work with Optifine or Oculus. If you have any suggestions or requests, you can reach out to me on the ShaderLabs Discord.
