what about a machinima-like video sequencer for cut scenees?
that could also output true video files, and why not some exporters for images, sounds and 3d models?
You can already export bitmaps, sounds and meshes from ZGameEditor. Simply click on a Mesh / Sound / Bitmap component, and use the "Save to file" ( it's called "Save as raw-file" on the Sound component ) button.
What is missing is a built-in export of video sequences, but you really do not need it - any windows video capturing and processing program can be used (I use VirtualDub).
