I don't know how the community makes contact lenses, but I have figured out my own way. I just use Maxoidmonkey's Jenn facial mask or Kurt facial mask, because they cover the eyes. All I have to do is to recolor them. Then, on the alpha, I make sure that the mask only covers the eyes and teeth but not the rest of the face. I would like to know how does the community make facial masks, so I can compare. My contact lenses is a pair of alien eyes, because I do not like custom eyes. Custom eyes are not removable with a mirror.

Why not look at some existing contact lenses? Download a set, and see how they're done? You can make a project from an existing one in Body Shop to examine the texture and alpha. From what it sounds like (alpha white over the eye and nowhere else), texture in that place, that's the normal way of doing it.

What do you mean, where do you get them? You make them. In Body Shop.

AFAIK - and it's been a while since I've done this - as a general rule the part of the texture that is mapped onto the eyes is at the side and top of the texture, not in the actual eye location in the centre of the face IYSWIM. This is one of my old ones:





It was made with a facial hair mask, I think - which, at the time I made it, allowed it to layer with other facial masks. You can do that in other ways now. A lot of the textures that map on the face have the eye stuff located in that part of the texture. All the actual real eye textures do (you know, for the eyes used in game). When I made this contact (this sets of contacts), they would layer over the eyes. Is this the sort of thing you are asking about?

It might be that the textures you are using do this differently.

If you're still reading this thread, I had a thought. I think Bruno - the guy who makes all the make up - must have used a face mask where the eyes are in place in the centre of the face rather than in the standard way at the corner as we were discussing. I say this because he made a set of eye makeup that was uneven (different) for each eye - something that is a natural human feature of course. With the standard way of doing things, you can't make each eye different because it uses the same graphic for both eyes so in order to have got the make up different for each eye he must have done it in some other way. Maybe you could PM him about it or look at his postings in the modding forums if there are any. If there is a mask where you can paint both eyes directly, that would allow you to have sims with different coloured eyes (using contacts, of course, though it might be a possibility to mod them into proper eye files) which would be a nice little feature.
