IR Lights Mod FAQ
10 questions players actually ask, answered.
How do I open the light editor?
Press the default keybind (usually a configurable key like 'L') to toggle the light editor screen. The editor will appear as a floating panel in your world, and you can move around freely while it's open.
What's the difference between point lights and spotlights?
Point lights emit light in all directions from a single point, while spotlights emit a directional cone of light that you can aim and rotate. Spotlights also support custom projected images, whereas point lights cannot.
Why aren't my shadows showing up?
Shadows require Iris shaders to be installed and active. Make sure you have a compatible shader pack loaded and that shadow rendering is enabled in both your shader settings and the mod's configuration.
How do I project an image onto a wall with a spotlight?
Create a spotlight, then in the editor select the projection option and load a black-and-white image file. Position and rotate the spotlight so the beam hits your target surface, then adjust the beam angle to control the image size.
Can I save and load my light setups?
Yes, the mod allows you to save light configurations so you can reuse them across different worlds or building projects. Look for the save/load options in the light editor menu.
Does this mod work with other shader mods?
IR Lights is designed to work with Iris shaders. Compatibility with other shader systems may be limited or non-existent, so Iris is the recommended choice for best results.
How do I make god rays or volumetric light beams visible?
Enable volumetric lighting in the mod settings, then add fog or dust particles to your world—the light beams will become visible as they pass through these particles. You can adjust the intensity and density in the editor.
Will lots of lights slow down my game?
Real-time shadows and many lights can impact performance, especially on lower-end hardware. Start with fewer lights and gradually add more while monitoring your FPS, and adjust shadow quality settings if needed.
Can I rotate lights precisely or do I have to use the 3D handles?
You can use either the 3D rotation handles in the editor or input exact angle values numerically for precise control. The numeric input method is faster if you know the exact rotation you need.
What file formats work for projected images?
The mod typically supports common image formats like PNG and JPG, and the image should be black-and-white for best projection results. Check the mod's documentation or config folder for the complete list of supported formats.
