UDK Terrain Lighting Problem

PeterK

Anyone know what's causing this, and how to fix it?

Rebuilding the lighting does not help, and it seems to manifest when I actively modify the terrain.

Is it your terrain lightmap resolution?

I'm sure you've probably tried that already and it doesn't look like that's the problem, but Ive had shadowy weirdness on terrains before upping the lightmap res.

I had this problem once and deleting my dominant directional light and making a new one seemed to fix it :S

Apparently, the problem was that the ground had been duplicated like 6 times. So it was overlayed, and therefore causing slight offsets in the lighting.

The reason this happened is because the ground was set to lock in position, and I must have accidentally grabbed it when drag duplicating other objects.

I selected the extra terrain meshes and deleted them, thereby fixing the issue.

Hope this helps anyone searching for a solution to a similar problem.
