Clustered Light Inspector

Clustered Light Inspector is a menu where you can control light_rt entities in real time in-game. There are various options that give almost a full control over the entity. You can control all the default light options, such as Constant, Linear, Quadratic, 0% Intensity Falloff, 50% Intensity Falloff, Minimum Brightness Threshold, Override Radius, Light Scale, Volumetric Light Scale and Volumetric Density, as well as Color using the color palette, Shadow Scale, Near Z, light's Pattern and entity's position in the map.

There are additional debugging and finding options. "Show Light Bounds" is relevant for light_rt and shows bounds of the light as a sphere. "Show Light Cone" is relevant for light_rt_spot and shows bounds of the light spot. "Show Only in Radius" will only display clustered lights in a specified radius. Additionally, you can toggle the specular reflection, the direct dynamic lighting, volumetrics coming from the light and this light's shadows.

Enabling The Inspector

In P2:CE, you can enable the Clustered Lighting Inspector UI using the devui_show light_editor console command, or by pressing shift + f1, opening the Graphics tab in the top-left corner and selecting the Clustered Light Inspector menu.
