Blender Line Art with tons of extra lines all over geometry in render

Method14253

Hi I am trying to use a blockout from Unreal engine to render with in blender but when I do I have tons of these lines all over, it only happens with blockout meshes from UE. Anyone know how to solve this to get rid of all the the grose looking lines? I am using the lineart Modifier rendering in cycles.

dunno how the line art shader works, but a guess is that it is reading the normals, and export from UE won't include shading information, so all the edges are hard. 
if you unlock the normals and smooth them by angle that may solve the issue.

You might check if the mesh has it's triangles separated and so try *Mesh -> Merge by Distance* and then *Face -> Tris to Quads* (possibly playing with some options like smaller distance, max shape angles = 60 degrees.. ).
