Over the years I have tried various different ways to inject new geometry into an actor. None of them have been completely satisfactory. The file below works to inject a head into  any figure, but the drawback is the 'bend 0' statement seems to be necessary, otherwise Poser will slowdown or freeze. { //INJ P4HeadGeom2.pz2 version { number 3 } actor head { storageOffset 0 0 0 objFileGeom 0 0 :Runtime:Geometries:femaleHeadOnly:femaleHeadOnly.obj bend 0 } }

Unfortunately this only seems to work properly with an 'objFileGeom' statement as above. Trying to inject a whole figure geometry with a 'figureResFile' line does not seem to work properly. And 'geomCustom' also has its problems, mostly to do with the fact that Poser will write a new obj file, when a figure that has geomCustom in it is saved to a palette. The "femaleHeadOnly.obj" is from the "Head Woman.cr2", and is part of the optional additional content supplied on the P6 CD.
