Man this sucks really.
I tried to create a new map, create new terrain, imported the landmass splines, and got again the missing references.
It’s clearly warning about the splines, while at the same time USING THEM.
I wonder how this is possible, as I only duplicated the original spline to build up my landmass. If this leads to an error, it should be denied.
Anyway, I have 22 splines in the terrain, in both maps.
The original map gives 21 warnings, while the re-made map gives 22.
I really don’t know where to bash my head anymore and I’m wasting a huge amount of time.
I’m wondering if the UE team is actually using these features, as I don’t feel I have done anything strange with this toolset.
The original map gives that flashing rendering and I absolutely don’t know how to solve it, while the re-made map requires to set up all the material layers again.
