Raytracing

Trace Bias

Bias of the tracing rays shot from this object.

The plane trace bias set to 0.0 and 2.0

TraceBias

Max Bounces

Maximum ray depth to which this object is traced. Beyond that depth, the object is invisible to rays. When rendering scenes with large number of objects, you can reduce this value for certain objects (typically crowds) to reduce the memory load.

The Sphere max bounces set to 16 and 0

MaxDepth

Terminator

Correct the shadow terminator artefacts. 0 for no correction, 1 for full correction.

The terminator set to 0.0 and 1.0

RaytraceTerminator

Detect Self Occlusion

Enable self occlusion detection during raytracing, to prevent self occlusion due numerical inaccuracies and terminator issues. This attribute is an alternative to the Terminator attribute above.

RaytraceDetectSelfOcclusion

EpsilonG

Enable using EpsilonG self occlusion detection.

Embree

Use Intel Embree as the raytracing accelerator.
