If you import an object and save it as a prop, the geometry is a part of the pp2. The props from DAZ and many other providers have an external geometry that you park in a designated folder and the pp2 calls that file instead of it being in the library file. The is external call. A pp2 with an imbedded geometry looks like this: version { number 4.01 } prop ribbon { geomCustom { numbVerts 1037 numbTVerts 1 numbTSets 0 numbElems 896 numbSets 3584 v -0.002831 0.608453 -0.000037 v -0.002596 0.608271 -0.000107 v -0.002174 0.608352 -0.000260 (with 1037 v lines, probably the same # vt, f and often vn) The pp2 can be a large file. This is one with an exernal call: version { number 4.01 } prop BBallCap_1 { storageOffset 0 0.3487 0 objFileGeom 0 0 :Runtime:Geometries:props:blbballcap.obj } The file will bring in whatever object is in RuntimeGeometriesprops and is named blbballcap.obj You can substitute a different prop as long as the name is blbballcap.obj ( and you remember to delete the blbballcap.rsr that is beside it. So you can alter the geometry and then give it the name of the old file and that will show up in Poser. Changing an imbedded geometry pp2 to an external call is a bit tricky. If you make any mistakes, it is likely not to work. Trav had/has directions for doing this at Morph World.
