Animation programming in UE4 and about GetEvaluateGraphExposedInputs

My input data was missed in my custom AnimNode and find out that I missed a call function.

GetEvaluateGraphExposedInputs().Execute(Context);

What GetEvaluateGraphExposedInputs().Execute(Context) does is copy all the input data into AnimNode. (That's why there is some cost...)

If you look at the AnimNodeBase.cpp and line 675 there are function FExposedValueHandler::Execute function.
