Hi,
What about exposing a C/ C++ API of terragen 2, so people can write their own nodes and dso's.
In addition it could be possible to call rays through Mental Ray. We write tons of plugins and shaders here.
I love the node based interface, it is great. A linux version would be highly interesting for us, as
we have a linux renderfarm running with Sun GridEngine. Actually we would like to use it on a feature film
Project.
many greetings
