I can't seem to find Morph Loader Pro in my Daz 3d 4.5 program, and I can't find where I would get the serial number. I'm currently using the 188.8.131.52 version. Any ideas of what's happening?
Morph Loader Pro is now part of DS4P as far as I know, and it shouldn't require a serial, I don't have one. Have you tried using the DS4P serial for this?
Does it appear in Help > About Installed Plugins, if so, once you get it loaded, you may need to go to Edit > Customize, and find it in the left hand pane, then drag it over to the right, and place it in any menu or toolbar you want it in. I just put mine in the Edit menu and it works OK.
