Imported datasmith texture issue, workflow issue

The platform is sketchup pro 2019, UE4.25.3 and lasted datasmith plugin.
I’m trying to work with UE4 only for days, and have a question with tank’s texture.
The left one with texture error was combined with main skp secen then imported into UE4 via datasmith.
The right one was directly imported into UE4 with datasmith. So what make this happened?

My current work flow is build basic building structure, and integrate 3D models in sketchup, then imported to Twionmotion. If I want to displace Twinmotion with UE4 as my final part of visualization, should I integrate 3D models in UE4 ?
