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. ❤️
