IterationVX Shaders bathes your Minecraft world in rich, colored light and sharp shadows. Built to run on Iris, this shader pack turns every torch, lamp, and glowing block into a real light source. Each glowing item casts its own specific color and creates crisp reflections on shiny surfaces. It gives the game a semi-realistic, path-traced style that changes how you see the blocky world.
Features:
- Colored Block Lighting: Every light source in the game emits a specific color instead of basic white or yellow light.
- Crisp Ray-Traced Shadows: Torches and lamps cast sharp shadows across the ground and walls.
- Path-Traced Reflections: Water and shiny blocks mirror the world around them accurately.
- Works directly with the Iris mod to process heavy lighting calculations.
- Blends a semi-realistic look with the classic blocky style of the game.
- Changes how glowing blocks look by giving them a true voxel-inspired glow.
