Working on a scene at the minute, it's no different in terms of setup to any other images I create, however, this one seem to be throwing a few problems. See attached.
I'm getting this a lot when using IR, I've never had this before IR is generally smooth and not blocky like this. I'm on Max2021 and Corona 6 (latest version).
The scene is also taking much longer than normal to render than previous scenes of a similar nature. Does the screenshot give any clues?
