Imported mesh shows gabs

[blendernuuub]

hi there.

when i import more complex props they have alot of gabs:

• mostly triangles and round shapes.

-the fbx not shows these issues when i reimport it into blender

• i tried to triangulate and choose diferent export options but it must be a unreal engine import problem since the fbx is ok

pls say whad i need to do here

Hi, in default in unreal you can see 1 side of an object, so you must consider this in modeling.
but how to solve this without modeling again …
go to your material and make it two side

Is the object supposed to be inside out? Maybe you have the normals flipped…
