Hi

I'm trying to figure out if there's a way to totally flatten certain areas of a procedural terrain. 

Using the altitude or flatten brushes in the terrain editor manage to flatten it only until a certain point. If I try to do the same in a zone, they won't manage to get rid of all the little spikes, no matter what.

I thought this could be done by connecting a mask bitmap to the terrain fractal function, to mask out the areas where the fractal shouldn't operate, but couldn't figure out how to do it.

Any ideas?

It can be done with the "Flat area" metanode, but by default, this metanode takes the camera position as the area to flatten. Maybe you could create, say cubes where you want the terrain to be flat, and feed that object to the metanode instead of the camera.

Thanks, great idea!

However, I couldn't figure out how to make an object the center of the flat area, instead of the world origin. I tried editing the metanode and setting an external dependecy for the object, but it won't connect to anything.

Any ideas?

I thought it was taking the camera mosition and not the world origin as the center of the flat area, sorry, bad memory.

So it is not possible using this method.

Any other ideas? 

Seems strange that there is no way to flatten part of a procedural terrain.
