One way to avoid exporting the same static geometry for every frame is to export it just once, and then export the rest of the scene (the cameras, lights, and any animated objects) as a regular sequence. kick can combine multiple ASS files and then render the result. For example:
kick environment.ass lights.ass character.0001.ass camera.0001.ass -o scene.0001.exr
- environment.ass is all the static geometry and the applied shaders.
- camera.####.ass is the camera, driver, filter, and options.
- character.####.ass is an animated character with its shaders.
