Rainbow Portals

🌈 Rainbow Portals An animated, shader-friendly Nether portal experience.

Rainbow Emissive Portals transforms the vanilla Nether portal into a mesmerizing, fully animated strip that cycles smoothly through the colors of the rainbow. Designed specifically for Minecraft 1.21, this pack uses per-frame emissive PBR maps to synchronize glowing colors with the portal’s animation — perfect for shader users on Iris + Complementary Unbound or similar packs.

- Seamless emission syncing using RME (Roughness, Metalness, Emission) maps

- Designed for Iris shaders, fully compatible with OptiFine-style emissive textures

- Lightweight and purely visual — no gameplay changes

🧱 Requirements: Minecraft Java Edition 1.21.X
