Basic RTX lights up vanilla Minecraft blocks with real-time ray-traced lighting. This shader acts as a lightweight demo that brings ray tracing to the game through Iris. It casts natural light bounces and soft shadows on default textures while keeping the original look of the world intact.
Features:
- Runs real-time ray tracing effects on standard vanilla blocks.
- Brings accurate lighting bounces and clean reflections to the game world.
- Works directly through the Iris shader loader.
- Keeps default textures clear without requiring custom resource packs.
- Serves as a simple demonstration of ray-traced graphics in Minecraft.
