Tali gets a fully functional face and reduced opacity of her visor so you can see it. Her body is adjusted a bit (slightly bigger breasts, narrower hips...
Tali's face was always a mystery since Mass Effect 1. The popularity of her character grew with ME2 and then ME3 to the point that she became a potential love interest for your Cmdr Shepard but through it all you never saw her face. In ME2 she removes her mask for Shepard (and he doesn't scream and run so she must have been human-like attractive) and you, the player, are left with your imagination. There's much to be said for that since it allows every player to assign her their own dream-girl image.
Well, this mod is here to take away your imagination and give you my own Tali face. Your imaginations sucked anyway. I give her here a full face that is fully animated like all other characters in the game. This would be a pointless exercise if I left her visor as it was: 98% opaque. You barely see hints of eye movement behind that purple haze and so her default face was correspondingly simple to go with that. She had only half a face, oddly formed at that, behind that mask. It served primarily as a place to hang her barely visible eyes. No more. She has a real face. She has real eyes with irises and pupils. She has eyelashes (after a fashion). Her face extends below her upper lip. Her skin is no longer a dark, featureless grey. In short, she now has a face that you'd LIKE to pull the mask away from, and you can see if fairly well, though not too clearly, so you can still toss in a little of your imagination there.
This mod intends to apply to Tali's main Mass Effect 3 uniforms, her default and her first alternate. Because it is a bit more involved, it will later come to include her DLC appearance too. As it stands currently, her default uniform is done and the mod file for this is available (as of Dec 6, 2013). Her alternate uniform should be ready before the end of Dec. Then the DLC work will proceed.
It is not so simple and straight-forward but I will also attempt to bring this mod backwards into ME2, and possibly ME1 so there is unity through the series.
Users reported some odd issues that suggested vertex weighting problems so I have searched for, and found and corrected. Also, the issue that caused her visor to revert to a filler texture/nontexture onboard the Normandy has been corrected. Tali works well as is but isn't in full finished form. At this time the main issues I am working on are her texture and the opacity of her visor. Texture-wise, she is too shiny and the visor at 70% opaque is too low (nearly clear in the game). I will tweak these items and hopefully release a fix version within a week or two.
