problems with meshes appears shadows

Hi i export using dathsimth and apears these shadows anyone can help me??

Hello.

If you rebuild your lighting the shadows are likely to go away.

If they don’t, then please review this article - A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

You’ll also be able to gain a lot of helpful information from our documentation - Lighting the Environment | Unreal Engine Documentation

Cheers

yes i rebuild and fix it Thanks!
