problem with octane sky and alpha
Posted: Wed Jun 16, 2021 4:27 pmhey folks.
i've done a bit of searching for this but can't find anything that matches up with what i'm seeing.
i'm trying to render out a scene element - very simple, just one kitbash building mesh that i'm trying to composite into an aerial shot. nothing fancy, just testing.
the problem is that when i click "alpha channel", my live viewer responds properly, giving me alpha, but the same exact frame rendered to .tiff includes the octane sky background.
even if i override kernel settings and specifically check 'alpha channel' in the render settings, i still get the octane sky background, no alpha.
this same behaviour happens with any object, if i just instantiate a cube and add an octane sky, i get the same result: alpha works in the preview window, but rendering to .tiff yields the sky background.
i'm guessing i'm just missing something? i have searched quite a bit so forgive me if i missed an existing answer!
additional, relevant info:
c4d R23, latest stable release of the studio plugin.
i'm guessing i could deal with this via a multilayer EXR output but hoping there's a simple way to do this for jobs that don't require that level of control!
