Copy entire scene before exporting? #16
Description
Right now, high-level modifications to objects (e.g. applying modifiers) are made by duplicating them first right before the export so the original remains untouched, then deleting them after the export is complete. This is a bit stupid as it does modify the scene itself and if something goes wrong, there will be leftover duplicates polluting it.
A bettter approach would be to do something like suggested here, save the entire scene somewhere else and operate on that copy. AFAICT the "Save As Copy" function could be used for that (save in some tmp dir), followed by launching a new Blender instance in batch mode as a subprocess to operate on that copy. This would leave the original scene entirely untouched.
Would help with #3.
