Weird Skeletal Mesh Import result

Hello, iam diving into the world of character creation, riging and animating. I have a very simple character wich i want to rig (well actually i rigged it with biped). Now when i export my model from max and want to import it into ue4 half of my model is invisible and rest is of totally random size. Anything i might have done wrong?

Here are 2 Screenshots, ill attach the max and fbx file as well
