3D mesh to Unreal

Hey all. Total newbie in 3D modeling. I just created the following mesh using the Bezier Curves but it Unreal shows like the sides are missing. Is it an import settings issue or something need to be filled in the mesh? Thanks

I don’t think Unreal recognizes Blender’s bezier curves. That would be my guess. Convert the curves to a mesh then try it again.

thanks for your answer. The curves were created as a mesh, used F to fill and E to scale it.

it had inverted normals. shift + n did the trick. solution found here: https://www.youtube.com/watch?v=7Oqayyw4yNU&ab_channel=passivestar
