Thanks guys, I totally forgot about Wilbur, I have it on my PC but it was collecting dust! ;+) About Ozone it's sort of pricey for just compositing atmospheres, there should be another way via the Vue Alpha renders no? I didn't see any infos on how Ozone interacts with Vue...but anyways I will wait and see because Vue 4 will cost about 200$ CDN in total while Ozone is almost 400$. :) Thanks for the infos though. Cheers!
