To see the geometric surface changes in your world, you need to activate the pack through your shader loader menu after launching Minecraft.
Activating the Shader Pack
1. Load into a singleplayer world or server so you can immediately see the visual changes.
2. Press Esc to open the pause menu, then click Options and select Video Settings.
3. Open your loader's Shader Packs (or Shaders) menu provided by Iris or OptiFine.
4.
Confirming the Effect Works
Once you return to your world, look closely at any nearby dirt, stone, or wooden surface. Instead of flat cube faces, every regular block should now look as though it is built from clusters of tiny mini-blocks arranged in a geometric fractal pattern. Check two quick things before you start playing:
- Block identity: Confirm that standard vanilla block textures and colors remain recognizable across the fractal pattern.
- Visibility: Walk into a shaded spot or indoor room to verify that standard lighting stays clear and readable across patterned surfaces.
If surfaces still appear completely flat, reopen the Shader Packs menu to make sure the pack is highlighted and that shader rendering is toggled on.
