I know a bunch of computer languages and a bit of Python, but I don't yet own Poser 5. (I only tried Poser 4 demo).

• Here are my questions:
• Which Python version does Poser implement?
• How much of the Poser functionality is accessible programmatically from Python? - Can you
• load objects,
• put them anywhere
• morph faces
• bend and twist body parts
• etc. ?

it's version 2.2.1 for poser5, you should be able to manipulate almost everything in poser with Python. SR3 for Poser5 added quite a few Python commands for the lights that were missing in earlier SR's.

The easiest rule to remember: Anything that you can do with parameter dials in Poser is accessible from Python. Only some of the other actions are properly reachable. You can load just about any kind of file, but the corresponding Save actions are mostly broken. If the Poser Python PDF documentation -doesn't- list a function, it's definitely not there; but if it -does- list a function, you still have to check to see whether it works! In general, the complicated actions that appear within a dialog box, like falloff zone graphs for magnets or the Joint Editor adjustments, are not available to Python. Sometimes you can "fake" these actions by various tricks like saving a file, modifying it, and re-reading it, but usually not.

Don't forget that you have access to the geometry data, so you can write custom im/exporters or other geometry modifications. As an example, there's a basic fractal generator shipping with Poser.
