Adaptive Undersampling When on, the Light Tracer uses undersampling.
When off, it samples every pixel. Turning this off can increase the detail of
the final rendering, but at a cost of rendering time. Default=on.
Initial Sample Spacing The grid spacing for the initial samples of the image.
This is measured in pixels. Default=16x16.
Initial sample spacing values
Subdivision Contrast The contrast threshold that determines when a region
should be further subdivided. Increasing this value causes less subdividing to
occur. Too low a value can cause unnecessary subdividing. Default=5.0.
Decreasing the subdivision contrast threshold can reduce noise in soft shadows and
bounced lighting.
Subdivide Down To The minimum spacing for a subdivision. Increasing this
value can improve render time at a cost of accuracy. Default=1x1.
Depending on the scene geometry, grids larger than 1x1 might still be
subdivided below this specified threshold.
