So, I modeled a character and am about to start to retopologize him, but I am kind of stuck. His eyes are meant to open sideways, rather than vertically. And I can not find anything on how this topology might work, and it is hard for me to conceive of compared to a typical human face where all of the pieces that open line up (mouth and eyes both have horizontal openings), where as my creature calls for a radical direction change in topology.
Here is the creature with some presumed topological edges marked out:
How would I go about the eyes? In pink I have marked ideal ways in which the forehead would deform, according to the eyes and assumed brow movement:
Would I carry the “top” eyelid across the center of the face? Would i move the lines vertically toward the forehead? Any help would be greatly appreciated.
Also, it doesn’t show as much in the model, but I am going to try to get the eyelids, when open, to bunch up as a bunch of fatty folded skin, as kind of sketched in the image below. And then when the eyes close, this skin unfolds to cover the eye and lay basically flat. Should I model the eyes closed and then try to use shapekeys to make them look folded and bunched when open (even though I would prefer to be able to do it with bones only)? Or should I model the eyes open and create extra geometry at the skin folds that will stretch and flatten out when the eyes close?
Thanks to anyone for any advice at all! Also, here is a blank photo in case anyone wanted to sketch how they think the edges should go…
