Alpha issue (C4D R21 and Octane 2022.1)

[juhatakabe]

Hi,

How can I save correct alpha channel when rendering with Alpha channel turned ON under Octane settings, kernels tab?
No matter if I have Keep environment ON or OFF. I keep getting dark edge around my subject when reading it in to Nuke. I am rendering out my image sequence using Render AOV Group and not directly from C4D save settings.

Using Cryptomatte AOV I managed to get proper alpha, but it will slowdown render time so I much prefer solving this issue somehow.

Thank you!
