It renders 3 identical images of my shot camera, one frame, single view. I want it to save successive images but just one of each revision or new render. When you use the scroll bar at the bottom it scrolls through 3 images with each 'render current frame' click.
What do you mean it renders 3? Three sequential frames? 3 render layers? 3 views in one image?
What happens when you click the "render current frame" button in the status line? Does this happen with a simple scene (just a cube)?
could this be saved images? that you have previously saved?
