*"Stefan has explained to me that the issues are largely technical. In a nutshell, Firefly internal architecture limits what you can do (both from an efficiency standpoint as well as certain capabilities)."

*???... Is the internal architecture of FireFly written in stone? Is the Poser development team unable to, or forbidden to, alter that structure? If for some reason it is not possible or worth the effort to upgrade FireFly into a more capable render engine, then maybe your suggestion to get a new renderer should be heeded. ...Or perhaps they could turn you loose on FireFly's internal architecture. :)
