Sorry, but what?

Ok, I was "playing" around in GC and this is the result. Look at the attachement. Does that look normal to you?

Not really a bug, but I want to see what you think.

well, such results are possible, but I would need a bit more information, how you get it. I looks like a zero edge + height correction, where the mid height is set very high.

Yep, that's right. I just thought it looked pretty cool. I checked it out in terragen and those lines where just slight adjustments to the height of the hill and did not have any extreme results.

yes, the 2D relief shows even extrem small elevation differences. For extrem results, try the noise control filter and play with weighting (W1, W2 ...)
