Les and Olaf, thanks for the information on PMD. I'm going to study that tomorrow, see if I can get it down. That would definitely be better than uploading a thousand OBJ files for morphs. ;-)

I've been working on squint morphs and eye morphs in general, since I'll need them as a base for the expression morphs I want to do, not to mention eye morphs themselves.
The attached picture represents no less than 10 or so start-to-finish-to-scrap-and-start-over attempts, one for the left side, one for the right. I have 33 eye morphs for right and left squint, and only two of them are what I would call decent. The left and right squint morphs are separated, one for each side.
Still a WIP though, and it's not a true "squint" since all that's being affected is the eye geometry itself and none of the surrounding muscles, but that comes later, using these as a base.
The problem is getting the lashes to follow along and play nice and stay even. ;-)
At least I've managed to not distort the geometry too much, and avoided texture stretching and polygon flipping.
I'll have a set of squint/close morphs to upload tomorrow sometime, hopefully. I'm still not completely satisfied with the looks of these.
