I was about to animate a humanoid character after rigging it but encountered an issue when copy and pasting flipped pose in Pose View. When I paste the flipped pose the leg and arm bones basically are inverted(in painful ways). I read up online and basically found that this is due to the way my bones are rolled. I tried fixing it, but having no luck figuring out which way the bones would be rolled. In Edit mode the model looks okay, but once I switch to Pose mode the legs become rotated.
Which way should the axis of each bone be pointing(x, y, z)?
