I love terragen, I can see how easy it is to set up realistic rendering with this powerful software; However, after some practice, I start to wonder how to actually integrate Terragen into a 3D workflow, for example: I have a rocket launch scene which was created in Maya, and I want to move that rocket launch scene into Terragen? How to do this? Or do I need to export a terragen animation and 3D track it with Nuke or After Effects, and then move the 3D object into the scene?
My second question is about the clouds, first, how to create a storm clouds? Second, is it possible to make clouds interact with objects? Thanks!
