“RTFX Generator” is a set of instruments for game
developers and motion designers to work with FX animations. The script
gives you the mix FX-animations possibility and quickly exporting them
as sprite sheets or sequences. Also you can generate previews for your
animation packs. It will be more convenient and easier to manage your
project, using the Preview generator tool.
However, you can use the FX pack without After Effects skills.
Pre-prendered animations allow to use all non-linear editing tools
support mattes and compositing programs like Adobe Premier, Adobe After
Effects, Sony Vegas, Final Cut, Edius etc.
