Win 7
Radeon 7400M

2.71

Summary:
blender -b just quits on windows with v2.7

steps to reproduce:
launch blender, save default scene as untitled.blend
The try to render in non-interactive mode. e.g.:

C:\Program Files\Blender Foundation\Blender>blender -b C:\Users\Martin\Documents\untitled.blend

And nothing happens (blender quits). use default scene which blender opens with. It renders interactively. If I repeat the above command without the "-b", blender finds and opens the file. Hitting the render button (interactively) does render an image. I have tried this with some of the benchmark files on BlenderArtists.org. Same results.

I have tried all sorts of arguments as listed on
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Command_Line
...can't get it working

Best regards
Martin

Uh, maybe was a bit quick on this one… I try to launch from the cmd box of windows, not from a windows console, right?

If it’s from a windows console, then I merged by mistake.

Else, it should work from console (M$ managed to break embeded py when ran without any std stream available, in there latest compilers…).

I was attempting to run blender -b from a cmd.exe window

Then please try to do it from a real commandline (console) window, here it should work at least.

This is most likely not a bug but a user error, the windows commandline is cmd.exe and blender/blender-addons#40907 is not affecting it.

The expected output for:

C:\Program Files\Blender Foundation\Blender>blender -b C:\Users\Martin\Documents\untitled.blend

would be something like:

Read new prefs: C:\Users\Martin\AppData\Roaming\Blender Foundation\Blender\2.71\config\userpref.blend
found bundled python: C:\Program Files\Blender Foundation\Blender\2.71\python
read blend C:\Users\Martin\Documents\untitled.blend

Blender quit

There will not be any images rendered, in order to do that you need to specify an output, format and frame, as outlined here: http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Command_Line#Render_a_picture

Example:

C:\Program Files\Blender Foundation\Blender>blender -b C:\Users\Martin\Documents\untitled.blend -o C:\Users\Martin\Documents\render -F JPEG -x 1 -f 1

which should result in frame 1 being rendered to:


C:\Users\Martin\Documents\render0001.jpg
