Interior lighting

Found in the Interior Lighting category on BP_DynamicVolumetricSky. See Indoor occlusion for how the system decides when a player is “covered”.

Setting	What it does
Auto Add Occlusion	When on, the system spawns a BP_DVSOcclusionComponent on every player automatically, replicated for multiplayer. Recommended on.
Interior Threshold	How “covered” the player has to be before the system swaps to interior lighting. Lower means a sharp pop between in/out; higher means a gradual fade.
Interior Sun Volumetric Scattering	God-ray strength when indoors (light beams through windows). Requires Volumetric Fog.
Interior Sky Light Volumetric Scattering	Ambient scattering indoors. Requires Volumetric Fog.
Interior Exposure Compensation	Brightens or darkens the camera response indoors. Negative is darker, positive is brighter. Useful to simulate eye adaptation.
Interior Height Fog Start Distance	Override fog start distance indoors (typically 0 or very low for atmospheric interiors).
Interior Volumetric Fog Scattering Distribution	Override scattering pattern indoors.

Tip

If you do not want the auto-spawn, turn off Auto Add Occlusion and add BP_DVSOcclusionComponent manually to whatever pawn you want it on.

• Fog and atmosphere: the global Volumetric Fog toggle these settings depend on
• Performance tuning: occlusion can be disabled for outdoor-only games
