Thanks for the answer. Our client asks a video to put on a big show screen ok 6k resolution. We are trying to convince him to scale down to 4k( 4096x4096)...hope he will accept! and we are looking for a good unity recorder to save images+ passes ( so we can compose then in AE if needed). It's a strange request but we would like to try to do this job inside unity instead to render from 3dsmax... Grazie!
