I have re-worked and optimized today the “Instantiate on Demand” function of the Pool;
And have added support for Pawn and skeletal Character classes to be pooled, this needs more testing. After more stability and stress tests I send 1.1 version over to Epic for an update somewhere at the end of this next week.
Edit:
Looks like they are ready (reds are pawns and cyan are skeletal characters);
Just some more tweaking and more testing to go
