Ockham,

please understand that the Poser 4 render engine in Poser 7 is solely provided for backward compatibility and not optimized for speed.

If you experience problems rendering with FireFly, please contact e frontier tech support via www.e-frontier.com/go/emailtech and describe step-by-step how to reproduce the issue. We will then investigate what causes it.

Edit: If you a rendering in a separate process when this problem occurs, please try to render internally instead and let us know whether that makes a difference.

Thanks,
Uli
