I have made some morphs using the v 4.2 morphs and I don't know how to make the inj and rem using studio.
How do I go about making the inj and rem for the morphs? :(

If you save V4 as a scene file, with the morphs injected but zeroed, then you can apply a pose preset saved from your character and only the morphs you need are loaded into memory. As yet there isn't a way of making an inj pose that will load the needed morph automatically, though there's meant to be an update to Injection Pose Builder at some stage (once that's out you could use the Poser format exporter to save a PZ2 with your morph settings and process that through IPB to make an Inj/Rem set).

I usualy use the "Save as Character Preset".

I have injection magic. Just found it on the tons of dvds I have burned over the years lol. I have maybe used the program once or twice for V3... is there a v4 file for it yet?
