I've tried injecting some V3 morphs into Laura without success - same with Maddie - because the morph channels don't exist in the figure, even when using Morph Manager. I had more success after using the ATC ("All Those Channels") Python script from the Free Stuff area. For example, I wasn't able to get the International Beauty morphs to work by simply injecting them.

I've also found, sometimes, that the morphs may load, but not display, and I've had to go into the CR2 in a text editor and change the "hidden" setting from "1" to "0."
