heyas; 1: yes. grab the prop, hit ctrl-i and turn on the origin. the green crosshairs show you where the center/pivotpoint of the prop are. you can move it with the three new dials that appear on your prop. (originx, originy, originz.) be careful, as sometimes when you go to move the origin, the prop moves. haven't figured out why, yet... 2: 6 megs for one boot?? that's big even for a whole figure! is the obj 6 megs, or the pp2? if it has a lot of morphs, the pp2 file will expand, as the morph vertex data is stored in there. but 6 megs?? i dunno. did you make it a conforming figure? if you plugged it into another figure's cr2, it might still have a ton of morph info in it. i know you said you made a prop, but.... 3: the mtl file is a text file that contains material settings for the obj that poser exports. you can delete them with impunity. :) it is used when importing the obj to other programs, to remember the material settings.
