Activating the Pack in Video Settings
Because Minecraft does not load shader packs natively, make sure you launch the game with a shader loader such as Iris or OptiFine active, and confirm the Renderlines Shaders archive is inside your shaderpacks folder.
1. Load into a world or stay on the main title screen, then open Options and select Video Settings.
2. Open the Shaders or Shader Packs menu depending on your loader.
3. Click Renderlines Shaders in the pack list so it is highlighted.

Confirming the Shader Is Working
Because Renderlines preserves the classic vanilla aesthetic rather than drastically altering colors or water, changes are intentionally gentle at first glance. To verify that the shader is active in your world:
- Inspect nearby trees and plants: Look closely at canopies and tall grass for subtle foliage shading and clean leaf details.
- Check the horizon and sky: Notice the refreshed ambient lighting and clean atmospheric visuals across the biome.
