There are many holes in the static mesh imported from Blender

Hello,

I created the static mesh with grid mesh in Blender. When importing into unreal, there are many holes in the static mesh.

In Blender:

mountains.jpg1524×860 81.1 KB

In Unreal:

What’s wrong with that? How can I fix it? :frowning:

Thanks & Regards.

It looks like maybe your face normals are flipped. Check the face normal direction in blender before exporting.

Thanks a lot! After adding triangulate modifier, the holes disappeared.
