Hi Guys, I’m a bit confused.

Until 2021 Octanes Alpha Output has been Straight by default when setting “Keep environment” to “off”.

Has there been a change in 2022 that I am not aware of?

When opening up the footage in After Effects it seems to be set to premultiplied, not Straight.
How do I get my Alpha to Straight? The Handbook for 2022 doesn't seem to exist.

Hi,
sorry, I'm not an AE user, but in 2022.1 SDK, the Premultiplied Alpha setting has been moved from Camera Imager node to Render Settings/OctaneRender/Main tab:

Thank you! It actually makes way more sense this way than before.
Its just confusing, when basic settings like that get changed.

By the way, does this mean, that enabling or disabling "Keep enviroment" doesn't have any impact on the aplha output whatsoever now?

As it should.
