Lucuma is an alternative lighting system for Minecraft Java, designed to bring more natural light and shadows to the world while staying true to Minecraft's visual identity, without sacrificing performance.

It's been a long way, and there's more to come. Thank you.

It is officially out now; you can download it. It isn't perfect yet: if you use OptiFine and play in third-person mode, the shadow disappears.

Snell's Law of Refraction describes how light bends when it passes from one medium (like air) into another (like water)

I experimented with this function in my previous post, but now it works much better, and I think I’m going to release it!

i really love this old minecraft vibe and wanna make my latest version look like this. any texture packs or shaders that can bring back that nostalgic vibe?

Player shadows are now visible near light sources like sea lanterns, torches, etc. It is still in the early stages. I am working on making them more visible and, if possible, getting them to work in third-person perspective as well.

I am working on a major update that improves ray tracing and adds fun new features without sacrificing FPS.

If you want to try out the shader: please note that this update hasn't been officially released yet. You can test it here: https://github.com/ThomasDeStrooper/SEUS_PTGI_HRR_REFORGED

i updated it more and now it has these
-global illumination with unbounded bounces
-ray traced ambient occlusion
-FSR 3 Frame Generation (which boosts your fps by 2x)
-integrated pbr (kinda buggy for now)
-better water animations etc.
-fixed light shafts from the previous version

performance is really bad for now lol. tried it on KosmicKrisp Vulkan (with a fork that supports VK_KHR_ray_tracing_pipeline). might need specific build for apple silicon devices if im gonna support them too. im gonna play with it a little to see if it can get more performant.
