Note: If you still would like to mess around with two cr2s referencing one obj, then it all depends what you are trying to accomplish. If you are hoping that the two cr2's could somehow end up merged together into a single figure - that isn't how cr2's work. You can get closer if the "add-on" file is a .pz2 file. But there are limits. The original cr2 would have to have a "ghost" part for each future part. Try this: From the original cr2 that contained all the parts, delete the "storageOffset" and "geomHandlerGeom" lines for one actor (one part). Load it - the part should now be permanently invisible, but still listed in the list of parts. Add those two lines into a .pz2 file, something like --------- { version { number 4 } actor rThigh:1 { storageOffset 0 0 0 geomHandlerGeom 13 rThigh } figure { } } --------- If this works, then could try deleting the addchild and weld lines for that "future part". Those lines would now be needed under figure. Something like: ... figure { addChild rthigh:1 hip:1 } ... I've never tried either of these myself ;-)
