HI Abstrax.abstrax wrote: "Keep environment" was always broken, because you can't use a simple alpha channel to cut out the environment from a normal render with environment. The border pixels around the cutout will always be a partial mix between environment and foreground which looks like wrong when you compose it onto a different background.
Sorry for delay but i had some jbs to finish and i was back to 2.16. No wi got some free time to test and show you my issue wiht this removeal of "Keep Environment" option. I can't believe I'm the only one renderign 32B files with Environment+Alpha at one go? With this workflow no passes needed and you can always replace BG if you wish since Alpha is embeded in 32Bit TGA. For 2.20 to get Alpha then ther eis no SKY in Backgorund (or IPR), and if oyu want SKY then you get empty (white) Alpha since it's turned off

Also if you render alpha separatel you then don't get that lens flare effect bloom/glare in 2.20

Here is how i used it in Octane 2.16 and before

And here is now problem in 2.2.x after removal of that option

So my quesiton is how to render it now (2.2x--->) same as in 2.16 at one go/file without extra steps/files/passes?
Thanks for your time
