Hello,
        I am attempting to save a series of images from a fly-through
of a performer scene. To do this, I am using the routine pfuSaveImage
alongside pfFrame in the part of the program that does the scene drawing.
The image files are created with the correct resolution, but are all
solid black. I suspect this is due to performer continuing to update buffers
as pfuSaveImage attempts to save them. Could anyone suggest whether this
analysis is correct? Can I force the program to wait on the save file
completing before moving on? I have the frame rate set to 25 at present.

My goal is to acheive a series of rgb files which can be converted into a
movie (mpeg etc.). Is my approach flawed, or will a simple modification
to the program get it going?

Any help much appreciated.

Colin
