OTOY Forums

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.
