Syntax
struct FExpressionOutputIterator
Remarks
This struct provides a way to iterate over the outputs of a given UMaterialExpression. It starts from the first output and advances through subsequent outputs until all are iterated through.
Usage:
UMaterialExpression*MyExpression=...;for(FExpressionOutputIteratorIt{MyExpression};It;++It){//Processtheoutput,e.g.It->Output->IsConnected();}
