Here's a really basic one that will do the job. It's set to step by 10; if you want 15 or something else, just change the line near the top from STEP=10 to STEP=15 or whatever. This will put the images in the same directory as Poser.exe. Important note: You need to have "Render to new window" turned off before starting this. Also, if you want to have previews instead of renders, change the line scene.Render() to scene.DrawAll()
