did you have auto generate collision on when you imported the mesh? its looks like a collision issue. to confirm this open the mesh in ue4 and click the collision button near the top then click simple (show in picture below). in the viewport you will see a set of green lines that is the simple collision. if this is whats blocking you then it will appear and make a face across that area.

if collision is the issue there are several options. you can reimport the mesh and not use auto collision. you can delete the collision. or you could make custom collision either in modeling software or by using box collisions in your level.

thanks ! now i know how do it properly
