Blender Python for Programmers 1

Render a cube using python from the command line: creates png.


Let's automate rendering a cube to an image file.

We first set up blender so that we can do python.

Change this panel to an info panel. Change the other panel to a python console.

Delete the distracting contents of the info panel

Change the output rendered filename to blender.png on the desktop

Render the cube to show what we are trying to automate.

This python code sets the output filename. Let's copy it and paste it into our editor.

Add a render statement and add an import bpy statement.

Copy that code from the editor, and paste it into the python console. It runs the code and renders the cube to the desktop as an blender.png.

Here's how to do a render statement. We google blender python render. In the search results, scroll to the the blender docs.

We scroll down to bpy.ops.render.render. Note the first two parameters are animation and write_still

We create a script to automate this all and run blender in the background to create an output image of our cube blender.png on the desktop

Save it as myscript to the desktop, make it executable and run it.

It creates this png output file on the desktop.

If you think this code might be worth trying, please give a thumbs up, and subscribe. Thanks for watching
