Functions

  Type Name Description
Public function Static UDynamicMesh *

ClearMaterialIDs ( UDynamicMesh* TargetMesh,
int ClearValue,
UGeometryScriptDebug* Debug
)

 Resets all Material IDs on a mesh to the given ClearValue, or 0 if no ClearValue is provided.
Public function Static UDynamicMesh *

CompactMaterialIDs ( UDynamicMesh* TargetMesh,
TArray< UMaterialInterface* > SourceMaterialList,
TArray< UMaterialInterface* >& CompactedMaterialList,
UGeometryScriptDebug* Debug
)

 Compact the MaterialIDs of the TargetMesh, ie remove any un-used MaterialIDs and remap the remaining N in-use MaterialIDs to the range [0,N-1].
Public function Static UDynamicMesh *

DeleteTrianglesByMaterialID ( UDynamicMesh* TargetMesh,
int MaterialID,
int& NumDeleted,
bool bDeferChangeNotifications,
UGeometryScriptDebug* Debug
)

 Delete all triangles in TargetMesh with the given MaterialID
Public function Static UDynamicMesh * Enables per-triangle Material IDs on a mesh and initializes the values to 0.
