An .rsr is the Mac resource fork in a separate file so that the Poser code ported from the Mac can run on a PC. A resource fork is just part of a file on a Mac (it correctly stores data and code separately within the file, unlike PC's). So by definition you don't have .rsr files on Macs. Also the problem with .rsr's on a PC is that being separate files they sometimes don't get written along with the main file, leaving the files out-of-sync. That they exist in PC Poser is a kludge, that they need to be deleted manually hen they get out of sync (because they lack a simple timestamp sync) is pure design negligence. Back to M3, isn't anyone else concerned about the huge round "muscle" on the outside of the shoulder? Bend the Shoulder (upper arm) to 45 to see it. Try the Skinny morph, and you'll see that hardly changes in size or shape. Same with Emancipated. As the figure gets slimmer the flesh on the outside of a man's shoulder has to diminish. It does on M2 BTW (another way to see it is to turn the Skinny dial negative - M2 shoulder bulges up huge, M3's barely expands). Look on V3M and you see it's exactly the same as M3 (and peeps complained about it then), but surprisingly the V3M Skinny morphs worked better there! Looks as if the mesh, the morphs and the JCMs were moved over wholesale from V3. The problem isn't major on V3 because the base CR2 doesn't have muscle/flesh on the outer edge of the shoulder - it's added in the various Muscle morphs so it plays no role in the slimmer/younger morphs. So when they added that muscle/fleash/growth to M3's base CR2 they needed to modify the Skinny, Yound, Emanipated, etc., morphs and JCMs in order to compensate, but didn't, even in SR1. As someone posted when M3 came out, we've paid $50+ for a genital CR2 and re-purchased V3M. Expected M3 to be weak on the musclebound end of scale, but I was surprised to discover M3 doesn't do lean well either...
