Returns

bool true if successful, false if not.

Parameters

Parameter

Description

InExpression

The expression to start at.

InOutProcessedInputs

An array of processed expression inputs. (To avoid circular loops causing infinite recursion)

OutExpressions

The array to fill in all of the expressions.

InStaticParameterSet

Optional static parameter set - if supplied only walk the StaticSwitch branches according to it. InFeatureLevel Optional feature level - if supplied, only walk FeatureLevelSwitch branches according to it. InQuality Optional quality switch - if supplied, only walk QualitySwitch branches according to it. InShadingPath Optional shading path switch - if supplied, only walk ShadingPathSwitch branches according to it. InShaderFrequency Optional shader frequency - if supplied, only walk ShaderFrequencySwitch branches according to it.
