The program seems to be ignoring the set minimum altitude setting on my latest render. The water level is at -797m. The beach is a gentle slope that slides up into hills. I want the grass to be on the hills here and there, but not on the beach. So I set the minimum altitude on the grass surface layer to -780... approximate the back of the beach. The fuzzy zone is zero. I did a quick render and there's still grass on the beach? What's up with that? Did I do something wrong?
I double checked whether I'd adjusted the wrong layer. I checked and rechecked my altitudes. I can't figure out what's wrong. Any other ideas?
-sigh-
Just figured it out. I had to check the "Use Y for altitude" box. I never had to do that before. It usually worked just fine without it.
At least the problem is solved. :)

Yeh sometimes the altitude is almost identical to the y, but ocasionally it isn't very close to each other... personally i think it should go off of y by default.
I believe significant negative altitudes can cause problems with the normal altitude controls. Something to look into.

I'm also having a problem with the preview window. The sky is showing up all blotchy. Not sure why, but it's been doing this the past couple of times I've run TG2.
I can't use the quick render to make minor adjustments, even the quick renders are taking 20-30 minutes on a default setting, and this is with Terragen as the only program running.
The sky is a graphics driver problem, I had never had it until is switched to windows 7 and then i easily fixed it by downgrading my drivers to vista drivers.
You can also adjust the depth buffer range with the [ and ] keys, which can help with the 3D preview sky problem. But yes, it's really just a driver issue.

Actually, I think it's more of a memory issue. I just saved the project and re-opened it and the sky preview rendered fine. I'm guessing that the Undo buffer was over-loaded or something, clogging up the memory with needless data. Also, now that I've re-loaded it, the quick render takes only 10 minutes instead of half an hour. I didn't even close and re-open the program. Just closed and reloaded the project. Weird.
I'll have to just keep flushing the undo buffer.

Are you sure that's what the problem was? Can you remember how much memory was being used for Undo? It says the amount in the Purge Undo menu item and the Undo History window.

I didn't look, but next time it happens, I'll check.
Thats odd, I have never had that issue. Any sky problems happened immediately on an open default scene and wouldn't go away until working drivers were found.
Must be something a little different happening.
