Can someone explain what is causing this world normal issue?

[laura.elizabeth]

Hi, I’ve just started using unreal and I’m not sure what’s causing this graphical issue. My models and normals look fine (all transformations applied, normals recalculated outside and switched from smooth->flat->smooth shading again for a new export) in blender, but when I import my models to unreal my accessories all have a strange ‘reflection’. The base object (body) loads texture ok, but everything attached to the body is having the issue.

Thanks for any advice. Cheers

The world normals in UE are definitely wrong. That viewport color codes directional vectors, and it should not look splotchy. If you are using a normal map, disconnect it to see if it is the cause. If that fixes it, you have made a mistake with the normal map (for example unreal uses a flipped green channel vs blender).
If that doesn’t fix it then you’ve probably made a mistake with your export or import settings and the issue is with the mesh normals.
