Parameters
| Name | Description |
|---|---|
| InProperty | The material property chain to inspect, such as MP_BaseColor. |
| 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. bInRecurseIntoMaterialFunctions Optional enable recursion into Material Functions - if true, will also return expressions from inside of MaterialFunctions. |
