ViewCaptureToFile 64bit issue

Rhino Rhino for Windows
1

I am working on a project where i am taking a stl. using ShowZBuffer and then trying to output a 64Bit PNG. currently when i use viewcapturetofile i am getting only 8 bit. is this a limitation of the command? does anyone know a work around. I am running Rhino on a windows 7 Server with an Nvidia Graphics card and Rhino 5 (64bit)

Any tips would be much appreciated. Should this be something done by the Renderer? i have tried that before and got the same issue, But am up for anything.

Thanks,
Tim

The z buffer probably is only 8 bits, it’s a shortcut to make the opengl display faster. Most renderers have the ability to output a separate z channel image.
