I've been experimenting with some of the tutorials and tests and wanted to grab frames for offline analysis.  I added the following Engine node to one of the test examples (test_dynamicCubeTexture.x3d):

  <Engine DEF='engine'>
    <RenderJob DEF='render'>
      <WindowGroup>
        <Window size='400 400'>
                <StandardViewarea grabFrames='150' grabFile='frame%04d.png'/>
        </Window>
      </WindowGroup>
    </RenderJob>
  </Engine>

But when I run the example in InstantPlayer beta 7, no frames get saved.  I tried just switching to grapFrames='1' with an explicit file name, but no frame got saved.  Is the grabFrames functionality disabled in this version of the player?

Thanks.

I just recognized that currently the images are stored to the root folder of the hard drive (C:\ or Macintosh HD) instead of relative to the scene's file.

By using a full path specification I was able to generate the frame image files.  Without it, they were not being generated at all.

Thanks.
