Superb work millighost. I was up all night playing : ) I registered an account here just to thank you.

Notes:

You can work on related morphs by giving each one it's own key and hiding all but the one you want when you export. As millighost notes above, you can see the other morphs in edit mode so I am a very happy camper with this setup. Model me with a huge grin.

Filename becomes the hidden internal name (as opposed to the exposed label designated by the shape key name) for the morph. So, for instance, I save the .dsf with MWM as the first three letters in the filename so all my custom morphs can be isolated when doing an FBX export.

X mirror the mesh for symetric morphs. BTW, proportional editing (o) doesn't work in X mirror.

Now we need to share our morphs : D. I'm working on a face modeling set. Here's one y'all will surely want. Just delete the .txt extension and stick it in the morph folder or a subfolder of that folder
