Skeletal mesh fbx import: Seam on texture when mesh contains of several meshes and is imported as skeletal mesh

[anonymous_user_b2b8ed1b]

I have a file that consists of several individual meshes. The meshes touch each other. The meshes are bound to a rig with animation. If I import the fbx as a skeletal mesh to UE4 and assign the materials there is a seam between the textures of the different meshes. If I import it as a static mesh the seam is not there.
I’ve already tried differengt import and export settings.

Reproduction steps:

1. Export a mesh that is separated into different individiual meshes including rig and animation as a fbx (in this case I used Cinema4D)
2. Import it to UE4 as a skeletal mesh (doesn’t matter if textures and material import is checked)
3. Open the Mesh in the editor and assign materials
4. There is a seam on the texture as you can see below on the picture. (picture01)

If you import the fbx as a static mesh (either from Maya or also Cinema4D) there is no seam (picture02).
The Bug is also in 4.13.

I solved the problem:
When I go to reimport settings and choose “import normals and tangents” as normal import method the seam is gone.
