Importing a Backdrop from Blender

Hi
I ve made a backdrop mesh in Blender and want to import it to UE4 as a static mesh with possibility to add custom created material.
After importing it doesn’t work right, mesh looks weird.
I am attaching files with a problem.

  1. Blender with Backdrop Mesh
  2. Imported mesh into UE (you can see in the middle of a Backdrop bend it looks weird)
  3. Applied material (you can see that it starts to stretch from a mid of a bend)
    Please help, how to make this seamless backdrop correct in UE.
    Thanks a lot!

Problem solved by clearing and correctly unwrapping UV’s in Blender.
