I was wondering if it’d be possible to (as the title suggests) calculate the vrayenvironmentfog as a separate pass that isn’t automatically calculated in the RGB pass - so basically just a check box on the atmosphere pass that says “don’t add to RGB”, or similar. My thinking is that I can get away with considerably lower sampling to the atmosphere (and just run noise removal on it) if it’s a separate element than I can if I’m trying to include it in the final beauty pass.
I have same question. How to render Vray Enviroment Fog just a element (can setting similar vray bloom-glare) only, doesn’t affect it to RGB channel. I want to post production final result in Photoshop.
