Quanta Shader

A simple, fast and beautiful Minecraft shader for Iris/OptiFine. Soft sunlight, gentle bloom, real shadows, dynamic clouds and lively water — tuned to look great while staying smooth on modest hardware.

A huge thank you 🙏

Quanta Shader exists only thanks to Javier G. Cimarras (javiergcim) and his amazing project [MakeUp Ultra Fast].

All the heavy lifting — the lighting model, the shadows, the water, the sky, the clouds, every clever optimization that makes this shader fast — is his work. This project is just a small, respectful fork: renamed, cleaned up, and slightly tweaked.

If you like Quanta Shader, please go and support the original author first. He deserves all the credit. ❤️
