Is this a place you've been before? lanzhan5656 built it as a cursed / fantasy / semi-realistic pack with atmosphere, bloom, colored lighting and shadows. It asks for potato-tier hardware at minimum and works with Iris or OptiFine on Minecraft 1.18 – 26.2. Licensed GPL-3.0-only, so the download is mirrored right here on MineSpecs — no ads, no redirects.

How to install Raincore
