If you're going to use a text editor, there's notepad++ which is free, however an easier way would be using Dimension3d's Poser File Editor which is here... It has a section under Editor, Morphs and Controllers. I've used it to remove channels and other things. Also under Insert Channel you can add Morph Targets. I've never tried anything like that on one of the Genesis 2 or 3's though... Once you've made your preferred cr2 you can save it for future use.

The dust settled, thinking "what a fine home, at least for now" not realizing that doom would soon be coming in the form of a vacuum cleaner.
