New update to Terraman on Highend 3d:
https://www.highend3d.com/maya/script/terraman-for-maya
Adds a proxy mode to enable low resolution proxies in a Maya scene to render high detail terrain at render time.
Used in my animation "Desert Dawn Drive" to generate deep OpenEXR to composite Maya elements with Terragen renders.
