Control (UI) Default Value Function
coordinatesystem object The coordinate system used by
displacementbound.sphere.
irradiance
maxerror 0.5 When set to 0, irradiance is computed at every shading
point, with no attempt at interpolation. Interpolation
with nearby irradiance values increases with maxerror
values.
maxpixeldist 30 Sets the maximum pixel distance between interpolation
sources.
photon
estimator 50 Sets the number of photons to consider when estimating
caustic effects.
causticmap N/A Sets the caustic photon map in which to store photons
during photon tracing. This also specifies which caustic
photon map to use when a shader calls the caustic shade-
Op.
globalmap N/A Sets the global photon map in which to store photons
during photon tracing.
maxdiffusedepth -1 Sets the number of diffuse bounces for photons. When
set to -1 the corresponding trace value is used.
maxspeculardepth -1 Sets the number of specular bounces for photons. When
set to -1 the corresponding trace value is used.
minstoredepth 0 Sets the number of specular bounces to store directly
from the light source. If set to 0, no photons are stored.
