strange shading on character

hi all,
when i imported my model into ue4, there’s some strange shading going on. im using blender, and here are the pics.
meanwhile, i asked the blender forum for help. the the hip crease seems to be a problem from blender itself, but the overall shading shouldnt be blocky like how it appears to be.

Well maybe you should start with uploading images in a size that we actually are able to see whats happening in your viewport and material…
And maybe you should add pictures of the expected behaviour…
