Post processing pass

[candersen181]

Hey Guys, I've been running some tests with the Octane render passes and I'm not entirely sure what to do with the post processing pass. Shouldn't it render on a transparent background? Is there a way to add this pass to my render in photoshop, fairly new to compositing. Also I noticed the z-depth pass doesn't seem to be working, haven't found a way to set the white and black distance in my render. Has anyone figured this out? Thanks

while compositing it in photoshop use screen, color dodge etc blending

What if I want add the post processing light effect with a 100% transparent background, no black?

Okay I figured it out using gimp color to alpha. Has anyone got the Z-depth working correctly? Thanks

There is a detailed tutorial on compositing at viewtopic.php?f=51&t=44267 and viewtopic.php?f=51&t=44350 which may help.
