Frequently asked questions

How do I enable path-traced lighting?
Path-traced lighting is enabled by default when you load Phoxel PT Shaders. If you don't see the effect, check that your shader pack is actually selected in Video Settings > Shaders and that your GPU supports the required rendering features.
Why are my shadows so colorful and weird looking?
Colored shadows are a core feature of this shader—they pick up colors from nearby light sources and surfaces, creating realistic indirect lighting. If they look too extreme, you can adjust shadow intensity in the shader settings to find a balance you prefer.
Can I use this shader with resource packs?
Yes, Phoxel PT Shaders works with most resource packs, but PBR-compatible packs will give you the best results since the shader is designed to use PBR texture data for realistic material properties.
My FPS is really low. How do I make it run faster?
Reduce path-tracing quality or sample count in the shader options, lower your render distance, disable reflections on water, or turn off PBR processing if your GPU is struggling. See the performance optimization guide for more detailed tweaks.
