This is a Shader that i specifically made to be fast and have pixel Shadows. It breaks many things like blindness so i dont recommend you use it except you want the same as me. Made by Kiwicat0_0, it leans vanilla-like and ships reflections and shadows. Expect it to run comfortably from potato-tier hardware upward, on Minecraft 1.21.10 – 1.21.10 via Iris or OptiFine. Licensed MIT, so the download is mirrored right here on MineSpecs — no ads, no redirects.
