Hi,
Ryan P. Wilson VFX supervisor from Return of the Ghostbusters here.
I’ve created a very easy to use proton stream tool that produces professional quality results. Better than GB 1 and 2. And better than Return of the Ghostbusters!

Give it a watch and please post your WIPS and renders on our blog post. I can’t wait to see what you come up with.
Best,
Ryan
