Octane 2023 vs 2022 - Post Pass Alpha Issue
Moderators: ChrisHekman, aoktar
Please see image attached. I'm trying to figure out why when I render to PNGs in version 2023, the alpha isn't acting like it used to in 2022. The post pass used to include the environment so the blooms wouldn't be cut out.

My workaround was making a custom AOV pass using the compositing nodes. Put a RenderAOV:Post over a Black Solid. See image. That "Post" Node is just an AOV Group node that I renamed. This works just as you'd expect the old post pass to render, just its named "Out1" instead of "Post".

Nobody should be exporting as PNG in the first place, a never ending worldwide misconception.Mayahi wrote:Please see image attached.

It can be as straight forward as a single right-click EXR export for no problem whatsoever. No workaround, hackery, trick.
Yes, thank you, I've seen that article before. The issue is that this workflow used to work in the older version of Octane, and now doesn't.

Nice to See Elsksa made a new forum account and continues to peddle the bizarre png hatred.skientia wrote:Nobody should be exporting as PNG in the first place, a never ending worldwide misconception.Mayahi wrote:Please see image attached.

Respectfully, "bizarre" underlies a lack of awareness on the subject.boxfx wrote:continues to peddle the bizarre png hatred.
"Hatred" is far-stretched and inappropriate.
Years of misconceptions and negligence despite objective truth and tangible substantiated evidences. Hence the importance of awareness. Otherwise, it ends up being another case of perpetuated entrenchment.
The forum is intended to be a helpful place, not to share fallacious subjective opinions about someone, or worse, express conspicuous gaslighting.
