Frequently asked questions

How do I turn on Voxray Shaders after installing it?
Launch Minecraft with Iris installed, go to Options > Video Settings > Shader Packs, and select Voxray Shaders from the list. The shader will activate immediately, though you may need to adjust settings for your hardware.
What's the difference between raymarching and raytracing in this shader?
Raytracing calculates shadows by tracing rays from the light source through the voxelized world, while raymarching steps through the voxel grid to create volumetric lighting effects in the air. Together they produce the deep shadows and atmospheric lighting Voxray is known for.
Why is my game running slowly with Voxray Shaders enabled?
Voxray is computationally expensive because it converts your world into voxels and performs raytracing calculations every frame. Try lowering shadow distance, reducing volumetric lighting quality, or disabling advanced effects in the shader settings to improve performance.
Can I use Voxray Shaders with other mods?
Voxray works with most mods, but may have compatibility issues with mods that heavily modify rendering or lighting. Test with your mod list and check for visual glitches; if problems occur, try disabling conflicting mods one at a time.
