Control (UI) Default Value Function
relativeshadingrate 1 Sets the value of the relative shading rate equal to
relativeshadingrate multiplied by any other
relativeshadingrate values in the Attribute stack. It can
also be passed two float values wherein the first value is
the relativeshadingrate and the second is a multiplier
on the shading rate in Z, for volumes, equivalent to
setting the depthrelativeshadingrate attribute.
resetrelativeshadingrate 1 Resets the relativeshadingrate to the given value. The
final ShadingRate used on an object will be the
accumulated relativeshadingrate multiplied by the actual
shadingrate.
diffusehitcache N/A Sets the point cloud or brick map used by
diffusehitmode and specularhitmode.
transmissionhitcache N/A Sets the point cloud or brick map used by
transmissionhitmode.
diffusehitcolorchannel N/A When set to the default, empty string, Cs, cs, _Cs, or _cs
are used for colorchannel.
diffusehitopacitychannel N/A When set to the default, empty string, Os, os, _Os, or _os
are used for opacitychannel.
frequency motionsegment Sets the frequency of shading execution for multi-
segment motion blurred geometry. The default is
motionsegment under which the shader is executed at
the beginning of every motion segment. In this mode,
the primitive variables bound to the shader are sourced
directly from each segment.
When set to frame the shader is executed only once for
the frame. In this mode, the primvars bound to the
shader are sourced only from the first motion segment
and all other primvars are ignored.
