I have been trying to import an entire level from unreal to unity but however it looses all its textures during the process. Please help

Due to technical reasons I have decided to shift from unreal to unity but however when I export models that I built from Unreal it simply looses all its textures.

what format? I find when I import an fbx into unity it NEVER comes in with textures. The shaders are all there but the texture field is empty. I need to import the textures separately, then drag and drop them into the texture slot of the shader in the inspector window

You can try using my tool : Exporter for Unreal to Unity - Lite | Integration | Unity Asset Store It exports materials and textures accurately.
