Sorry Doc but you're suffereing from a known (and reported) bug in the code. When you start up P5 (post SR1) with any non-native Poser units defined (in Edit->General Preferences), the conversion is initially incorrect. The reason is that the conversion factors were changed in the main code as per the SR1 readme file, but the code that stores the conversion factors in the preferences file was not updated, hence the old, incorrect value is the initial one used. Fromm the SR1 ReadmMe.txt file: * Poser's real world units have been re-scaled for greater accuracy by changing the scaling factor to 8 from 8.6. * In order to change to the correct value you have to reselect the unit type in the Edit->GeneralPreferences, whilh will cause the correct value to be reloaded from the code.
