I need to create a simple semi-flat terrain for putting buildings on, but I need it to have something to it to put grass and things on.  I don't know if I am stating this well or not.  I don't want it totally flat but nothing sticking up, in the form of a mountain or rock formation. 

Am I making any sense?

a simple way of doing this is to create a simple terrain, add erosion to your liking, and then use the filter altitudes button in the terrain editor ( 2nd icon from the left in the upper right corner of the terrain editor), then use a filter from the round clip collection. Done.

Okay, kewl.  I will give that a try.  The more and more I play with this, the more and more I like what it can do.  When it wants to play nice that is.  There are days when I'm certain this app is part cat.

The stuff in the Altitude Filter was exactly what I was looking for.  Thanks so very much.

You can also build a terrain with mountains, then just scale down the vertical 'Z' axis with the 'Numerics' tab scale tool, at the top of the object list

I made a few low but lumpy terrains by using the 'render clouds' filter in photoshop, saving that and using it as an image import in the terrain editor.

Thanks for the other options gang.
