I'm making a short film, and it will have a couple scenes with a "post-nuke Iraq." (Iraq after a nuclear explosion) I will be using a green screen, but need a way to create the new "post-nuke Iraq" background. I also need to create a forest and a beach with that software. Some standards of the software include;
1.) It must be 100% FREE
2.) It must render and/or export into AVI file format
3.) It cant be a demo version (No demo limitations such as; No saving/rendering, 30 day trial, etc.)
