The AR Shadow, Reflection & Light Catcher allows you to easily illuminate video with scene lights.

How to enable

  1. Check World Settings > Use New Light Catcher

Parameters

  • Diffuse Override and SpecularOverride determine light strength and proportion of diffuse to specular component.

  • Light Multiplicative Power and Light Additive Power control blending light with the video. SceneColor = SceneColor + Video * Light * Multiplicative + Light * Additive theory is that Multiplicative can brighten the video and additive adds color.

  • Light After TAA if checked light compositing happens after TAA, it is more expensive but looks better when using DLSS or ScreenPercentage < 100

  • Add GI adds Global Illumination to Catcher

Excluding lights

Specify which lights should not contribute to lighting up the catcher. By default, all lights are used.

  1. Select the light
