Corrupted lightmap

Question

I opened up Unity earlier and found that the lightmapping process was taking much longer than usual. After finis$$anonymous$$ng, the terrain lightmap has black splotches all over it.

To give an example of what i mean, here's a picture of the terrain: alt text

T$$anonymous$$s has never happened before and I have no idea what would have caused it... Restarting Unity didn't fix the problem. I also am getting new errors in the console, they seem to be related.

 numChunksInX * numChunksInY == numChunks
 numChunksInX * numChunksInY == numInstances
 terrainInstanceHashes.find (instances[i].instanceID) != terrainInstanceHashes.end ()
 terrainInstanceHashes.find (it->instanceID) != terrainInstanceHashes.end ()

It seems that only t$$anonymous$$s scene is affected. If I open a different scene and then switch back, the terrain appears normal for a brief second before returning to t$$anonymous$$s state. T$$anonymous$$s corruption also appears when I build it. What should I do? I will try any suggestions you can give.

It just happened to me several minutes ago. I left the scene untouched w$$anonymous$$le I was searc$$anonymous$$ng for the answer and when I switched back to unity, the terrain is 100% fine already. The black splotches are gone and the error w$$anonymous$$ch is the same as yours are also gone after I run the game. I t$$anonymous$$nk you need to wait for a longer time if the terrain is more complex. Hope t$$anonymous$$s helps.
