Fix Low FPS or Overly Dark Areas with Luminia Shaders

Path-traced lighting is demanding. Lighting also behaves differently than in vanilla. If your game stutters or your builds look too dark, try the steps below.

Improve Performance

1. Lower your render distance. Open Options > Video Settings and reduce the render distance. This is often the biggest single gain.

2. Adjust the shader options. Go to Video Settings > Shader Packs and open the settings for Luminia Shaders.

• Look for options related to lighting quality and shadow quality.
• Lower them one step at a time.

3. Test in the same place. After each change, return to the same spot in your world. This lets you compare the results fairly.

4. Turn off what you don't need. If you only use the shader for screenshots, switch it off during normal play and turn it on when you want to capture a scene.

Brighten Dark Interiors

With Luminia Shaders, light spreads by bouncing off surfaces and casts real shadows. Spaces under buildings and foliage can look much darker than in vanilla.

• Add light sources inside rooms. Don't rely on daylight through a single window.
• Place lights near walls and ceilings. This lets the bounced light spread farther into the room.
• Check brightness options. Look in the shader pack settings for any brightness or exposure options and raise them gradually.
• Check the vanilla Brightness slider. You can find it in Video Settings if the whole game feels too dim.

If you change a setting and the result looks wrong, reset it in the shader settings menu and try a smaller adjustment.
