I'm looking into render passes but making zero progress.

It's a single frame image I'm trying to render and it seemed an ideal time to tackle layers and passes... I've got as far as batch rendering a layered PSD, which seems ideal, but I'm stumped when it comes to passes. I've created a layer with all relevant geometry and lights and created a few associated passes... but get nothing in the PSD layers.

Every tutorial I've watched goes about things in a different way - some create individual layers and change the attributes, some use contribution maps, others seem to simply do as I've done. Many of the tutorials seem to be geared to creating 32 bit files for use in Nuke or similar - I just want a PSD file to manipulate to create a single image.

I'm at a loss to know where to start solving this....

thanks

thanks, I'll take a look at these. Not too expensive too user added image

turns out I was getting separate passes from my batch render - I was outputting a layered PSD which was showing as pure black on the file preview on my mac; when I opened it in photoshop the passes were there! user added image

it does seem a fairly simple procedure at the start of a basic scene. I start getting confused when I've got multiple display and render layers, material overrides (which I can never seem to get rid of) on some, different lights and emitters on another .. especially if it's a long render - it's very nerve wracking - there always seems to be something to go wrong or for me to forget to check on!
