Vivid Swift Lighting Shaders FAQ
10 questions players actually ask, answered.
How do I install Vivid Swift Lighting Shaders?
Install a shader loader mod (such as Iris or OptiFine) first, then place the Vivid Swift Lighting shader pack file into your shaderpacks folder. Restart Minecraft and select it from the Shaders menu in Video Settings.
Will this shader pack work on my low-end PC?
Yes—Vivid Swift Lighting is specifically designed for performance on standard and low-end computers. If you're still experiencing lag, try lowering your render distance or disabling other visual mods.
Why do my blocks look washed out or too bright?
Adjust the brightness and color settings in the shader options menu (accessible from Video Settings > Shaders > Shader Options). You can fine-tune lighting intensity and color saturation to match your preference.
Can I use this shader pack with other mods?
Vivid Swift Lighting works with most mods, but may conflict with other lighting or visual overhaul mods. Avoid running multiple shader packs or lighting mods simultaneously.
Why are there dark spots or visual glitches on certain blocks?
This is often caused by incompatible resource packs or conflicting mods. Try disabling other visual mods temporarily, or switch to the default resource pack to isolate the issue.
How do I get better frame rates while using this shader?
Lower your render distance, disable shadow quality if available in shader options, reduce your resolution, or close other applications. Vivid Swift Lighting is already optimized, so hardware limits are usually the bottleneck.
Does this work on servers or only single-player?
Shader packs only affect your client-side visuals, so they work in both single-player and multiplayer. Other players won't see your shaders, and servers don't need the mod installed.
Why does the sky look different or strange?
Vivid Swift Lighting modifies sky and lighting calculations for its visual style. If the sky looks broken, check your shader options for sky brightness settings, or verify your resource pack isn't conflicting.
Can I use this with OptiFine and Iris at the same time?
No—use either OptiFine or Iris as your shader loader, not both. Iris is generally lighter on performance, while OptiFine offers more customization options.
My game crashes when I load the shader. What do I do?
Ensure your graphics driver is up to date and that you have a compatible shader loader installed. If crashes persist, try removing conflicting mods one at a time, or reinstall the shader pack.
