> Quote - What I'd really like to see is the ability for Poser to use other render engines as plugins. Not sure how complex that would be in terms of software engineering, though....

It is possible already. I haven't worked on it  for quite a while, but export to 3rd party render engines from within Poser is certainly possible with Python.
