Blender to UE4 using UE4 animations?

Edit: Figured it out -> Hey, thanks for the UT3 rig, the IK seems to work there, but it doesn’t work on the ShooterGame rig that you provided?

Edit: Figured that out as well -> Also, I have no idea how the IK constraint works in the UT3 rig case, because there’s no target and no pole. The actual deforming bone is acting as an IK target, apparently. Yet if I assign a pole everything goes wrong(the foot gets rotated 180 degrees) and the pole doesn’t actually do anything.

Best scenario ever would be if someone wrote a proper FBX exporter for Blender so that a normal rig would work. There’s also the question of how do Epic’s Maya Rigging tools set up their rigs. I don’t know if it’s a normal rig or not(are their bones actually rotated).

Also - how did you figure out how the bones have to be rotated for the ShooterGame rig to work? Trial and error?
