Rendering multiple object groups

[surrealdan]

Hi, been using render groups and wanted to know if there's a way to render multiple object group/render layer nodes. For example, I render out a group of trees with its alpha, and the ground layer with shadows in another pass, similiar to maya render layers/batch render. Is there a way to render it all in one pass? instead of separately? Thanks

I don't think this is currently possible since each group/layer is associated with a single render node, and you can only render with 1 node at a time.

Ah makes sense. Thanks for the info!

If you just want to render several layers in an unsupervised session (say overnight), you could use a batch file to execute several render commands in series, specifying a different render node for each.

I'd have to look into that. Not very advanced in scripting, but where could I get a script like that?

You just need basic understanding of BASH or BATCH files, there are lots of tutorials about starting a command and waiting for it to finish (app clears processes). What type system are you using? I could write something where you just need to replace the "CMD" strings.

I can help with a simple bash script (for Mac or Linux). Can't be much help with Windows. Doesn't Windows still use .bat files?

a script for windows would be great!
