I have created a mesh of part of a road I intend to use with splines.
All the normals have been recalculated, scaled, etc. (To the best of my knowledge.)
Whenever I import it into Unreal Engine 5.1, it is transparent on one side ( and not the side I want)
If I flip it 90 degrees I can see the material\texture
But if I flip it all the way it goes black.
I have tried two sided materials in Unreal, flipping the normals in Blender, etc, etc to no avail.
Any assistance or guiding direction would be much appreciated
