Hat tip: Andy Jones on the Softimage mailing list

You can use xsibatch -processing to render scenes with Arnold. With -processing, xsibatch uses a Processing token instead of a Batch license, so you’re not limited by the number of Batch licenses you happen to have. Back in the days before third-party renderers, -processing for was for non-rendering tasks. Now it’s for non-mental ray tasks!

I was sure I tested this long ago, but obviously I must have made a mistake on my command line.

 xsibatch -processing -render //server/project/Scenes/example.scn

Here’s actual proof in the form of a screenshot 🙂
