OptionalendLast scene to be rendered. Accepts by 'Scene Zero-Based Index', 'Name' or by 'Scene Object'.
OptionalrenderTotal number of frames to render.
EXPERIMENTAL Use a negative value to render backwards. For backward rendering, BeamToIX first has to consume all the frames forward, bypassing all middle frames, only after can render backwards.
OptionalrenderFirst render frame.
If startScene isn't defined it will be relative to the story, otherwise is
relative to the startScene.
OptionalstartFirst scene to be rendered.
Before start rendering the startScene, first,
BeamToIX first has to consume all the frames until it reaches the
beginning of Scene.
Accepts by 'Scene Zero-Based Index', 'Name' or by 'Scene Object'
BeamToIX still has to render all the previous frames of active scene bypassing the middle frames, but it won't be render to disk and it will bypass any unnecessary frames.
