Poser Python Scripting F.A.Q (Last Updated: 2024 Sep 18 2:50 am)

We now have a ProPack Section in the Poser FreeStuff.
Check out the new Poser Python Wish List thread. If you have an idea for a script, jot it down and maybe someone can write it. If you're looking to write a script, check out this thread for useful suggestions.

Also, check out the official Python site for interpreters, sample code, applications, cool links and debuggers. This is THE central site for Python.

You can now attach text files to your posts to pass around scripts. Just attach the script as a txt file like you would a jpg or gif. Since the forum will use a random name for the file in the link, you should give instructions on what the file name should be and where to install it. Its a good idea to usually put that info right in the script file as well.

Subject: Render a real-time depth map, but how to turn the scene background white?

The script belowautomates the setup and rending of a real-time depth-map of a Poser scene, then reverts the changes to the scene. My question is about line 50, which opens the background color-picker for the user. There the user still needs to manually change the scene background color to white, then is expected to press 'OK'.  Is there some way to change the background color of a Poser scene automatically, by using Python code?

scene.SetBackgroundColor (1.0,1.0,1.0) .. this is from the poser 11 Poser Python Methods Manual.pdf, but still works in 13.

Consider me insane if you wish, but is your reality any better?

Wonderful, many thanks Bwldrd. I had run several searches for "background" across my Poser Python folder, but didn't think to search for SetBackground.

Here is the final working fully-automated script, tested on both Poser 11 and 13.  Useful for those needing a quick depth pass render, but who not want to go to the trouble of setting up an Atmosphere, using a special .MT5, or rendering in Firefly to .PSD with z-buffers on.


# Make a quick depth-qued auto-render from Poser.
# Version 1.0 - December 2023.  Tested in Poser 11 and 13.
# With thanks to bwldrd for the 'SetBackgroundColor' tip.

# From a saved Poser scene, auto render a quick real-time depth-map
# as a .JPG on white, then revert the scene to the last saved scene file.

# NOTE: The user will needs to change the output directory 'dirPath=' to their chosen path.

import poser
import datetime

# Set up the saving and timestamp parameters. Change the save directory to suit your needs.

dirPath="C:\\Users\\WINDOWS_USER_NAME\\FOLDER_NAME\\"

current_date = datetime.datetime.now().strftime ("%a-%d-%b-%Y-%H-%M-%S")

# Are we dealing with a Poser scene?
scene = poser.Scene()

# First, we make the Ground invisible. Thus, no ground shadows or grid.
# Comment out these two lines with #'s if you dont want this to happen.
