Thanks for DELETING my topic.

It shows apparently how do you treat developer. I had the audacity to ask how it is possible one can retarget animations from Skeleton A to B, but not from B to A. And I called your retarget manager it’s real name. Now my topic is deletet. It shows how much do you care about developers and helping them with problems caused by your engine. Thanks for opening my eyes.
Thanks god there are some other good engines too, which unlike UE 4 can easily handle such common problem, as animation retargeting.
