Curved bridge

I tried to simplify it since I’m not making any progress

  1. edit poly modifer and attach it then face selection and set id’s

ID 1

ID 2

Then select ALL Then unwrap UVW and hit flatten mapping

Then export and import

But everthing stays the same. Is there a step I’m missing, like an save UV map, or export feature I need selected? This seems like it should be pretty straight forward.

Also, I note that in other tests, if I increase the number of faces on a polygon, I don’t get the extra faces when I import to Unreal.

For example,

I create 3 tubes, and if I change the number of sides between the tubes that imports correctly, but if I change the number of height segements that doesn’t. (all after UVW unwrapping of course).

Side note, I swear I’m not stupid, lol
