Stairs collision problem

Hi,
first I would like to apologize for my English. Second, I do not know why but i can’t write a new topic to “Content Creation” forum so I’m sorry if this will be little off-topic. So, my problem starts when I export mesh with collider from 3D’s max as fbx. Collider have name “UCX _…” Of course, the rest of the name is the same as original mesh. When i import this fbx file to ue4, the collider looks different (see picture) and I can not figure out why. Can someone please help me? :slight_smile:
