and please share why you think CL Never did this Sorry, but I won't share any interals from past employers. But I'm wondering what makes you so shure that an OpenGL Poser would require a core rewrite, given the fact that you haven't ever seen the Poser source code or any other internals? Don't get me wrong, I'm with in the opinion that not having OpenGL in Poser sucks - OpenGL ranked high in my personal wish list for Poser 5 features. But I think it's realistic to expect or at least to hope for OpenGL in version 6, in both the user's and CL's interest.
