You know, I work in Max building stuff for Poser all the time, I never let the thought of exact scale ever bother me, as far as I'm concerned there is nothing fixed in any 3D program, everything is relative. After saying that, however, Poser sizes are right at the small end of what Max can use, I scale everything up 1000X to work on it, and .001X to export. I figure Vickie is 6' tall, and size everything based on a real item (like my cannon in Freestuff) from her. If you work Poser size a lot of things don't work correctly, and Max gets confused on the display at times. max also gets confused on how big a Max "unit" is at times, adding to the observation that it is all relative, anyway. Also, there is a bug in the Habaware OBJ export if you scale more than one group up on export- beware!
