Hi,
Thanks for you quick and comprehensive reply. If it is ok I’d like to ask a couple of follow-up questions.
I am not sure I completely understood what you meant in the first paragraph. What I need is standart linear exr output (no sRGB, no other LUT, pure linear data). I work in Nuke so dont know it AE supports linear workflow, but in VFX it is a necessity. It might be that UE doesn’t work in linear under the hood, but I’d actually would be surprised if it were otherwise. I just don’t know how to make UE to give the pure data out.
As far as the AA goes double res is a useable workaround, the problem is when you need a 3k or 4k output. Double res then isn’t usually supported.
Regarding the render passes I am really confused about how they work in UE. I not only didnt find one I could define myself (but that might be possible with some sort of UE blueprint). But more importantly I didn’t find any settings for the premade ones (for example for AO you need to be able to setup the sampling and distance, you should also be able to set sampling mode and possibly chanels for all of the passes. In UE I found only how to add them and remove (I might be missing something here).
As far as the absolute depth pass I saw that in UE there is ‘depth’ and ‘depth.world units’ (also both can be either custom or scene). Do yiu know the difference between those? Could it be that the ‘world units’ has absolut unclamped distance values? Clamped is workable, but doesn’t have as much detail.
