There's the scary-looking https://github.com/opencog/blender_api/blob/master/textures/eva.COL.png and then a "subdermal" evaSubdermal.COL.png and then some skin gloss texture eva.GLOSS.png and perhaps a skin-transparency (so the subdermal shows through??? guessing wildly) in eva.DISP.png .. there are textures for the inside of her mouth, the eye.png but also eyeCornea.png and finally, long long eye lashes.png I spent multiple sessions earlier this week, trying to figure out how to wire it all up and was completely stumped. I can see that original blender file access these textures. I can also see many dozens of animations, but again, was stumped as to how to make them run. I think its important to port these, because they all looked pretty good (to my untrained eye. Certain cough cough sculptors in the house were less than happy.) The only "major" flaw was that if you used the various viseme animations (visual phonemes) while she's talking, and then made her smile, the mouth would go weird. --linas > except the eye's displacement (if you zoom in really close) which I've not > figured out yet. > Shadows/lighting are not tested, I can continue on this in a few days, but > hopefully this would be sufficient for you to start getting some visuals. > > The blend file is here > https://github.com/Radivarig/blender_api/blob/update-materials/Eva_nodes.blend > > Best, > Reslav > > > On Wed, Mar 2, 2022 at 5:23 PM Mark Wigzell <[email protected]> wrote: > >> Hi Reslav, >> Hey great!
