No, Poser 12 has other issues. :) You may have better luck with it for Firefly, albeit I heard people reporting great Firefly success with P13 as well.

I'm curious--have you reported this as a bug yet? This one, or the material room crash, or any of the issues you mention here? (I know ghostship2 already did for Superfly)

'no other 3d app can do this'--is a bit spurious.
