Risr

Risr is a dedicated Vulkan-based Shader mod designed to sit on top of VulkanMod. It completely bypasses legacy GLSL and uses native Vulkan SPIR-V binaries (.spv) to bring advanced shader capabilities to Minecraft.

Features

• SPIR-V Native: Loads custom .spv shaders packed in vulkan.zip files.
• Iris-like UI: Integrated directly into VulkanMod's video settings, providing an easy-to-use menu to manage and toggle shaders.
• Built-in Visual Vibrance: Comes pre-packaged with "Visual Vibrance," an exclusive shader pack built to emulate and improve upon Bedrock Edition's RTX/RenderDragon pipeline.
• Advanced Pipeline Injection: G-Buffer injection to allow custom Render Passes for Terrain, Water, and Entities on Vulkan.

How to Create a Shaderpack for Risr

Risr uses a custom vulkan.zip packaging format containing compiled SPIR-V shaders. This ensures optimal loading times and complete compatibility with VulkanMod.

Structure of a Shaderpack

A typical shaderpack for Risr should be structured like this:

visual_vibrance/
├── shaders/
│   ├── gbuffer_terrain.frag.spv
│   ├── gbuffer_terrain.vert.spv
│   ├── gbuffer_water.frag.spv
│   ├── gbuffer_water.vert.spv
│   └── post_processing.comp.spv
├── pack.properties
└── pack.png

Compiling Shaders to SPIR-V

You must compile your original GLSL/HLSL shaders to .spv using glslc or dxc:

glslc src/gbuffer_terrain.vert -o shaders/gbuffer_terrain.vert.spv
glslc src/gbuffer_terrain.frag -o shaders/gbuffer_terrain.frag.spv

pack.properties Specification

This file is required for Risr to detect and validate your shader.

name=Visual Vibrance
version=1.0
author=bludos
description=An enhanced Vulkan RTX experience.

Packaging

Zip the contents of your folder (do not zip the root folder itself) into a file named vulkan.zip. Place this in your minecraft/shaderpacks directory.

Compilation

Risr requires JDK 21.

To build the mod:

./gradlew build
