FWIW I've modified this today for the particle shot I'm doing and added depth as well as scene scale knobs, so you can manually push it back/forward in Z. Also an option to auto scale the geo so as you increase the scene the geo scales the same apparent size in frame.
Also I found an 'addLayer {rgba.beta}' line in the last one so you should
remove that if you dont use this version (same version name)
Cheers
Howard
