Gen/G2F/Dawn don’t have morph channels, instead DS reads the data from any DSF files in the figures Morphs folder, and creates the dials that way, so the simplest way to get a “clean” figure to work with, is to simply move the contents of the Morphs folder some place outside of the Morphs folder. Load a new figure into an empty scene, do the morph work you have do, save it, delete the figure from the scene, put the DSF files back into the Morphs folder, and load a fresh copy of the figure back into the scene.
From my own work with DS it appears the problem with the Property Editor is pointless ERC code, the more “dummy dials” you have on “body parts” the worse it gets, until it gets to much and DS either goes (not responding) or crashes.
I know there aren’t “channels” per se. It’s just that it takes too long to move those nearly gigabytes of material between folders every time. As a PA I have every DAZ figure release plus my own work plus the DieTrying conversion plus a bunch of unofficial character morphs by other PAs, etc.
What I actually ended up doing was:
Install Genesis Starter Essentials to another library folder called DAZ4Test. This Genesis comes with only the Basics. Then I deleted those from data files.
Renamed key files from “genesis” to “genesisC.”
Use this version for my morph loading/ERC freezing projects. It loads Property Editor in a very reasonable amount of time.
Do not compress the morph files on saving. Afterward, do an edit/replace on all instances of “GenesisC” to “Genesis” in the morph in Notepad++.
Cut/paste the thus-edited morph over to my main Genesis install for testing and packaging. If necessary, re-save from there to create the presentation color I want or compress it,, etc.
Once the initial install is set up it’s much faster than trying to cut/paste my entire Genesis/Base/Morphs folder twice on every project!
