Please note - the problem I described exists solely in the PoserPython functionality. If you turn on the Render to Window option and then close said window after a render - you can still save the image. What you cannot do is something like the following: poser.Scene().SetOutputRes(640, 480) poser.Scene().SetRenderToNewWindow(1) poser.Scene().Render() poser.Scene().SaveImage("png", "C:test.png") The last line above will save a blank image instead of the expected render.
