This is a debugging or "draft-quality" integrator that implements only the direct lighting portion of the light transport. It is not designed to produce "final-quality" images. Since it doesn't implement indirect lighting paths it cannot produce reflections, refractions, or other global illumination effects, nor can it handle any effects that require a volume integrator.

 

Parameters

ParameterDescription
int numLightSamplesControls the number of light samples for direct illumination per camera hit point. The default is 4.
int numBxdfSamples

Controls the number of Bxdf samples for direct illumination per camera hit point. The default is 4.

 

Standard AOVs

On top of regular LPE-based AOVs, this integrator outputs a number of standard AOVs typically used by compositors.
