bool | GetRerouteInput
(
FExpressionInput& OutInput |
Get the reroute node input pin. We could use GetInput, but we'd loose const correctness |
  |
UMaterialExpression * | TraceInputsToRealExpression
(
int32& OutputIndex |
Trace through the graph to find the first non Reroute node connected to this input. |

void | GatherStrataMaterialInfo
(
FStrataMaterialInfo& StrataMaterialInfo, |
Recursively parse nodes outputing strata material in order to gather all the possible shading models used in a material graph output a Strata material. |

  |
bool | IsResultMaterialAttributes
(
int32 OutputIndex |
Marks certain expression types as outputting material attributes. |
  |
bool | IsResultStrataMaterial
(
int32 OutputIndex |
Marks certain expression types as outputting Strata material. |
  |
FStrataOperator * | StrataGenerateMaterialTopologyTree
(
FMaterialCompiler* Compiler, |
A starta material is a tree with FrontMateiral being its root and BSDF being leaves, with operators in the middle. |
