render multiple scenes at one time?

Been looking a little bit but I can’t seem to figure out how to render multiple scenes at one time.

So I have 10 scenes with the same items and I want to render each scene with the items in different locations then composite them together. I can do it manually, but I was hoping there was a way to just hit render once and have all the scenes render sequentially.

Is there a way to do this?

Thanks in advance for any help.

Hi, you can write a small batch script or use a small software from a german Blender forum user.
Doku is in german but software is in english.

Command line options for simple script

Thanks for the input.

I don’t know scripting, but will look into Doku.

Google for batch script on windows, it is more or less put a line for each command in a .bat file

@ECHO off
cd c:<blender installation directory>
blender -b file1.blend -o //render_ -F PNG -x 1 -a
blender -b file2.blend -o //render_ -F PNG -x 1 -a

Was wrong link, mib

… especially if you have a few extra “old” machines lying around …

(BTW: Unix, Windows, Linux, OS/X, all of these can do command-line scripting. And, it’s actually “noticeably faster,” because Blender isn’t running its graphic user interface.)

I do suggest rendering to “MultiLayer OpenEXR” files, with lots of individual layers turned-on. Plan on using compositing to put together (and “tweak”) the final image. Therefore, tell the renderer to give you as many separate information channels as it can do, and use a file-format that (by design) will not throw-away or compress-away any of the numerical information.
