I would never have known about the M4 installer looking for poser.exe, thanks I'll give that a try and see if I can get it installed. So from what I understand, unlike V3, M4 and V4 don't come with any morphs at all included, and I have to purchase their respective morph packs, correct?

Quote - The expression inj will not physically change anything on it's own.  You did nothing wrong.  It will create additional dials in the model's properties.  If you have a problem conceptializing the set up, let me know and I will screencap what to look for.

That would be great, thanks, no hurry though, as I've got a boatload of info to weed through anyhow, but it would be nice to see how that setup all works. Much appreciate your taking the time to help out.
