Why Shaders Matter
The URBAN pack includes PBR (Physically Based Rendering) textures that only display their full potential with a compatible shader. Without a shader, you'll see flat textures instead of realistic lighting, reflections, and material properties.
Installing a Compatible Shader
1. Ensure you have Optifine installed (required for shader support)
2. Download a shader pack like BSL, which is recommended for this resource pack
3. Place the shader file in your shaderpacks folder
4. Launch Minecraft and open Options → Shaders
5. Select your shader from the list and apply it
Adjusting Shader Settings
Once active, open the shader settings (usually by pressing a hotkey like O or accessing it through Options). Look for options like:
- Reflections: Enable for realistic water and wet surfaces
- Normal Maps: Ensure this is on to see texture depth
- Ambient Occlusion: Adds shadows in crevices for realism
Start with default settings, then tweak based on your performance and preference.
