DEFAULT: LumenRayLightingModeOverride

Use the project default method

Type:

HIT_LIGHTING: LumenRayLightingModeOverride

Calculate lighting at the ray hit point. This method gives the highest reflection quality, but greatly increases GPU cost, as the material needs to be evaluated and shadow rays traced. The Surface Cache will still be used for Diffuse Indirect lighting (GI seen in Reflections).

Type:

2

SURFACE_CACHE: LumenRayLightingModeOverride

Use the Lumen Surface Cache to light reflection rays. This method gives the best reflection performance.
