I saved "Don" as an .obj from P5 and then imported him back into P4. He measures just under 6' tall. See pic above. I also opened a P4 scene with a "standard" 7' doorway and P4 people (male & female). Then I loaded "Don" from the "Figs" library and he appeared to be just under 6' tall (using my old scale prop. See next pic. It would appear that there is a scaling problem with the "real world" units in P5. To be continued ...
Remember ... "With Poser, all things are possible, and poseable!"
