Well I guess it depends on the industry, depends on the studio. I nor anyone I’ve worked with has ever handed over raw renders to someone to work on, but then I dont work in vfx but arch vis. TBH in my time, ive only ever worked with a couple of people that spend more than 10 mins doing post work, just isn’t the time available. Projects only last 4-5 days, a week if you’re lucky.
It has to look good straight out of Vray, so, working lens fx etc are super important to me and everyone else I work with. I only spend about 30secs in lightroom on each image.
