opal Shaders

Opal is a shader loader mod. It's its own engine, and it loads normal OptiFine/Iris shader packs. You don't need to edit anything, just drop a pack in and pick it.

The main goal is more and MORE FPS. In my tests it beat Iris on most packs, but it depends on the pack and your PC.

What it does

• Runs on Vulkan and OpenGL (Vulkan is usually faster)
• Has its own shader screens for packs and settings
• Supports packs that use custom images, like rt and PathMax
• Fixes shader problems at the engine level, not per pack

What you need

• Minecraft 26.3
• Fabric Loader and Fabric API
• Vectors Mod
• Java 25

Good to know

• This is an alpha, so expect bugs. Please report them with the pack name and your log
• Don't use it with Iris, only one shader mod at a time.
• Works with Vectors for more FPS.
• Packs with compute shaders can be missing some effects, and some packs still look a bit different from Iris
