 # This script is an example of how you can run blender from the command line (in background mode with no interface)
 # to automate tasks, in this example it creates a text object, camera and light, then renders and/or saves it.
 # This example also shows how you can parse command line options to python scripts.

 # Example usage for this test.
-#  blender -b -P $HOME/background_job.py -- --text="Hello World" --render="/tmp/hello" --save="/tmp/hello.blend"
-# 
-# Notice all python args are after the "--" argument.
+#  blender --background --factory-startup --python $HOME/background_job.py -- --text="Hello World" --render="/tmp/hello" --save="/tmp/hello.blend"
+#
+# Notice:
+# '--factory-startup' is used to avoid the user default settings from interfearing with automated scene generation.
+# '--' causes blender to ignore all following arguments so python can use them.
+#
+# See blender --help for details.
