i am facing an issue while importing a twinmotion 2025 project into unreal engine 5.1

I’m facing an issue while importing a Twinmotion 2025 project into Unreal Engine 5.1.

I successfully imported the project using the Datasmith plugin, and the geometry is showing up fine. However, none of the materials are appearing in the scene. The textures seem to be referenced correctly (I can see the texture paths), but the materials themselves are either missing or not applied to the mesh.

Details:

  • Twinmotion version: 2025
  • Unreal Engine version: 5.1
  • Using Datasmith plugin for import
  • No error during import
  • Materials are simply not showing in the viewport
  • In some cases, I see invalid DrawScale/DrawScale3D warnings in the output log for a few actors

I’m wondering:

  • Is there a specific plugin or Datasmith version I need to use for Twinmotion 2025 compatibility?
  • Is UE 5.1 compatible with TM 2025, or should I upgrade to 5.3 or higher?
  • Has anyone else faced this material issue after importing from TM 2025?

Any help or suggestions would be greatly appreciated. Thanks!
