This is an issue as old as the very first version of Octane, and I always avoid the question because I'm lazy.
I have a scene full of transparent objects, and all my textures have an alpha channel with transparency information in it. Is there a way to tell the Opacity slot to use the alpha channel? It's gonna be a pain to extrapolate the alpha channel for every texture, into new files to apply in the Opacity slot... :x

Ok, I kinda figured it out...
If you drag your texture file in the Graph Editor, it asks you what type of image you want to import: color, grayscale, or alpha channel.
You basically need to drag your texture file twice, one for the diffuse color, and one for the opacity. Hopefully this won't count the same texture twice in memory...

I always got the same questions. Will try you way.

Thanks
