Weird dark spots in corners only in between sloped surfaces.
If anyone have some suggestion how to solve following problem, please help. I cannot get rid off dark spots like this (They only appear where the upper surface is sloping.):
UV layout seem to be ok - enough spacing, but I see some analogy between uv layout elements and dark spots like below:
Increasing Indirect lighting quality does not solve the problem. Actually I get more of them than when it was set to 4 or 6.

You don't have enough lighmap resolution to get proper results. You should have less meshes attached together because like this it's "impossible" to achieve realistic results! You just can't set high enough (the max is 4096) lightmap resolution (not to mention calculation time)! So let's say you have this max setting. Then as you can see on the attachment your wall gets 1024 res all together! ...which might be enough (I guess you had a lower res... if it was 2048 then your wall has only 512... ...)! But you would have a faster build calculation with separate walls and lower lightmaps not to mention to control completely your lightmap resolution per mesh! The other thing is: snapping corners to grid/pixel + straightening edges! You'll have a lot less (or not at all!) artifacts if you won't have diagonal edges but everything is 90 degrees! You can stretch your lightmap uv island to a certain amount (I've even seen extreme cases!).
