[FacilityProjectedMesh] Couldn't compute mercator bound because the mesh has no object child

Hello everyone,

I’m building an airport in MSFS2020 and currently facing the following issue. For some reason, my projected mesh texture is not showing up in certain areas, as you can see in the image, where some areas are fine but others look transparent. The texture looks fine on 3ds Max, but on the sim, it looks like this. I get the error placed on the title, which I’m assuming has something to do with it.

Does anybody have any ideas?
