I've been working on my own units and it keeps making problems. First I tried making a knight with spear on cataphract model and in game the knight was laying on the ground next to the horse instead of on the horse. Then I was making a light swordsman with axe on vulture model and in game light swordsman was turned 180 degrees which means his head was where his legs should be and opposite while his weapons were placed right. After that I made a heavy cavalry with knight's body, Landsknect halberd and praetorian shield and in game it was just a big red bubble which means it can't load. When I test the models they work perfectly with animations and I don't know what is the problem. Can somebody help me?
