when you auto-group it does not split the mesh into peices at all. the only way of doing that would be to spawn or create props from them in the group editor and why would you do that!? you dont have to do that IF your imported mesh (now a single mesh) WAS split in your 3dproggy THEN re-attached giving you overlaping edges (of the conjoined peices). WHICH in poser will show up as thick lines in mesh/poly mode OR break-lines (between each body part) in line mode. bone from there. im no 3d modeler but i have played with setup room and this is how ive done it. never used phi builder so i cant say either way is better than another, im just saying this way works, like the manual says it should. though it wasnt as descriptive as i am.
