Yesterday I had to render a 3d animation for a colleague working on 3D television. He needed a short street-view video with depth map. Because there were some problems with some real world footage he wanted to use, he asked me to create an artificial video in Blender. After I created a simple scene with some models from www.katorlegaz.com, I wanted to render the whole animation overnight on one of the computers in our lab. I had some trouble with getting the command line arguments right and wanted to share this, in case someone else has the same problem.
I first tried
-b is for background mode, so I could log out from the computer after I started the job, the options
-a is for (according to the command line help):render frames from start to end (inclusive), only works when used after -b I thought this was the bare minimum to get the job done. However, nothing happened but this:
Compiled with Python version 2.5.
Checking for installed Python... got it!
ERROR: No camera
Huh, no camera? There was an active camera, the scene rendered just fine from the UI, I checked my file over and over and everything seemed all right.
