"I like how it's looking! still one bug (which if anyone can help me out with would be amazing, i can't seem to figure out how to change the direction of the players velocity when they go through the portal.... "
Im going by memory here, but if I recall correctly, you can Get Player Controller -> Set controller rotation. Then use the portal's yaw to set the controller yaw and you should be facing the right direction when you go thru the portal :)
