1 Adistira shader is a photorealistic pack built entirely from scratch. It brings PBR lighting, soft shadows, and ambient occlusion to Minecraft, with volumetric clouds, an atmospheric sky, and realistic water featuring reflections, waves, and refraction.

TAA and FXAA keep edges clean, while ACES tonemapping gives a natural, cinematic look. Extras include normal mapping, parallax, emissive blocks, and colored light.

Each dimension has its own fully custom atmosphere — a lifelike Overworld, a cosmic End, and a fantasy-lit Nether.

Requirements: Iris (tested & recommended) — may also run on OptiFine. A labPBR resource pack is optional for normal maps and parallax.
