Hello,
I was wondering if anyone knows how to lower the poly count of Terragen rendered terrain. The poly count is a shocking million or so :eek: This is certainly not what I need in game design.
If anyone knows how to lower the poly count of exported terrain from Terragen or how to lower it before export please let me know.

Once the geometry is imported into blender, use a decimate modifier. This will lower the poly count while attempting to keep the shape of the mesh. Since it’s a modifier, you don’t have to make the results permanent until you are sure it’s what you want. A slider controls the decimation amount in real-time.
Thanks so much, it works wonderfully. 
Here’s some pics of what I did with it:
