After building lighting, black splotches show on landscape
When Lightmass needs building, the landscape looks great - however as soon as I build, I get the effect seen in the attached image. This is not related to the material, as it happens when any material (or none at all) is applied.
I cannot figure out what the issue is. I have resized the lightmass importance volume, both to cover the whole landscape and only covering the player area - both produce the same results.
The landscape has been resized to fit the world, as it was too large, I'm unsure if this has caused the issue. If so, should I resize during creation or after creation?
An unrelated sub-question, but should I have the lightmass over the entire landscape or just the area a player can walk? It is possible for the player to see most of the landscape.
I recreated the terrain - didn't touch a thing. Left the scale, rotation etc completely alone and there were only very small splotches in very hidden areas - but they could quite possibly be from using the lowest quality build setting.
I then created a new landscape for testing purposes; in which I only rotated the landscape, I didn't scale it at all. Same splotches appeared that you can see in my early screen grabs.
I then did another test in which I created a landscape, scaled it to 200% and did not rotate it. Not a single problem. SO it appears to be a bug related to rotating the landscape.
Thank you for your help, and I hope my tests may help others.
I had a similar problem and none of the solutions I found solved it.. Then I made my landscape material 2 sided and the black splotches went away.
