Once the shader pack file is placed in your shaderpacks folder alongside a compatible shader loader like Iris or OptiFine, you can activate it directly from the pause menu without restarting Minecraft.
Selecting the Shader Pack
1. Load into a world or stay on the main title screen and open Options.
2. Click Video Settings, then open the Shaders (or Shader Packs) menu.
3. Click Radiant Amber Glow in the list of available packs and apply your changes.
4. Return to your world and allow chunks to reload so the warm lighting and soft shadows take effect.
Verifying Key Visual Effects
To make sure the shader is rendering properly rather than falling back to default vanilla lighting, check a few immediate visual cues around your character:
- Look toward the sky during the day to confirm that sun rays display a glowing bloom effect.
- Inspect nearby terrain edges and trees to see soft shadows blending across blocky landscapes instead of flat vanilla shading.
If you see standard vanilla lighting after selecting the pack, return to the shader menu and verify that shader rendering is toggled on in your loader's controls.
