Spheres & Physics Illuminated works on standard vanilla worlds right away, but it is built as the dedicated lighting component for the Spheres project. Combining both packs unlocks the intended fantasy visual style.
Loading Both Packs Together
1. Open Options and click Resource Packs.
2. Move the Spheres resource pack from the available column to the selected column on the right, placing it near the top so its textures take priority, then click Done.
3. Return to Options, open Video Settings, and go to your Shaders menu.
4. Select Spheres & Physics Illuminated and apply the changes.
Choosing Between Standard and Fantasy Visuals
When both the resource pack and shader pack are active at the same time, the custom textures and dedicated lighting combine to produce a distinct fantasy look across every biome. If you prefer traditional Minecraft textures for a specific survival world or server, simply move the Spheres resource pack back to the available column while leaving the shader pack enabled. The shader will continue to provide clean color tones, soft highlights, and upgraded contrast on vanilla blocks.
