Landscape Rotation Causes Issues with Lightmass
Detailed description of the issue:
When building lightmaps for landscapes - if it is at 0,0,0 rotation, it all works fine, yet when rotated in any way it causes huge black splotches everywhere.
I posted the issue a while back, and have recently found the issue again with any landscape with any rotation values.
Although the more the rotation, the worse the artifacts. 90 degrees, for example, will produce a few in various areas whilst 180 degrees will ruin the entire landscape.
Action 1: Create landscape by importing a heightmap.
Action 2: Rotate landscape - via the creation tab or after creation.
Action 3: build lighting.
Thank you for your report. I was able to reproduce this on my end and have entered a bug report, UE-8308 to be assessed by the development staff.
