Once Painted Dream Lighting Shaders is placed in your game's shaderpacks folder alongside a compatible shader loader such as Iris or OptiFine, you need to activate it from your video menu to apply its cartoon art style to your world.
Selecting the Shader Pack
1. Launch Minecraft and load into a singleplayer world or multiplayer server so you can immediately preview the visual changes.
2. Press Esc to open the pause menu, then click Options and select Video Settings.
3. Open the Shader Packs (or Shaders) submenu.
4. Click on Painted Dream Lighting in the list of available packs. If you do not see it listed, click the button to open the shader pack folder and verify the archive is placed directly inside shaderpacks rather than nested inside an extra subfolder.
5.
Verifying the Visual Style
Step outside into an open biome during daytime to confirm the pack is active. Blocks and skies should immediately shift into soft, painted colors with warm, gentle lighting tones while keeping their familiar vanilla shapes and textures.
