Want to soften the harsh line around the Iris where it meets the Sclera

RAMWolffRAMWolff Posts: 10,212

More tweaks to my upcoming first character pack for Genesis 8 Male, Gino.  I have a little niggle I'm not liking about this eyes though... he's got a pretty sharp cut off between the Iris and the Sclera.  MOST of the eyes I see for digital characters have this nice soft transition.  

I've even looked at other characters bought from DAZ3D and can not see any difference between my maps and those so not sure what's going on with why I get that really sharp transition between the two areas.  

Any suggestions, tips, tricks or otherwise would be most welcome.

Thanks so much

  • Without seeing your setup, it's hard to tell you what to change. It looks like you have no limbal ring setup and no translucency on the eyes. Both of these things will give you a harsher line. I recommend Project EYEray for nice transitions. The UV is different but solves a lot of eye issues.

    Yes but this is for a for sale character I've developed so really don't want to use another persons set up.  Just wish there was a tutorial so I could learn how to fix it for my character and subsequent charactes to follow.  :-)

  • Looking at a couple of the G8 characters I have, there is a sharp line between sclera and iris. The sclera and iris are separate face groups but part of the same geometry, which uses the eye texture map.  These include both sclera and iris, and the outer edge of the iris map is very sharp.  So I suspect you would have to soften this a little, but transitioning into what the sclera map shows, and that feels tricky.  If the sclera and iris were separate geometries, you could overlap one with the other and use a transparency map.

    That said, the line in real human eyes is variable, and can look pretty sharp until you get very close.

    It's something I see rather often in characters and usually its a deciding factor if I buy or not, from your image it's hard to see the way you made the mesh for the eye, if it bulges out enough for where the lens would be. No expert there but I guess thinning out the iris mesh to the edges and giving the cornea the right refraction value might help.

    After all what I would do is getting the eye ray product and have a very close look at the way they solved the problem, because from the promos those look really good

    Oh, sorry, you misunderstood me.  This is a character for Genesis 8 Male, I didn't morph the eyes. I agree with folks sentiment on buying as realistic as possible.  While I'm happy as apple pie about the skin and all the rest this harsh sharp line around the meeting of the sclera and the iris is a dead giveaway

    Hmmm, Google is our friend... found this thread here:

    @agent unawares. First:

    any idea how to get the eyes to look real on gen8, they look unrealistic

    Basic quick setup:

    Turn Cornea Bulge to 200% and adjust the iris inwards by ~20% (iris not necessarily necessary but cornea bulge is).

    Load a Gen 8 eye shader.

    Kill reflectivity on sclera and iris (iris is depending on taste but because DAZ flagship eyes setup has the iris bleeding into the sclera, sclera needs no reflectivity or a mask in order not to produce an impressively ugly reflection ring in the iris).

    Make sure Cornea and Eye Moisture have Thin Walled turned off. This allows refraction. If Eye Moisture has heavy bump turn it down a lot.

    But now! Your eyes are very dark because the diffuse textures are not set up for Cornea and Eye Moisture to be volumes. So set your diffuse strength on sclera and iris between 2 and 4. If the sclera veins render too red kill off a bit of that with a blue/green tint. You can also adjust the textures in photoshop to avoid the saturation issues, preferable but less straightforward.

    Turn up bump on iris for more detailed look.

    This should look much better than default. Adjust as needed from here. You may have to turn up Transmission Distance on the Cornea and Eye Moisture to allow light to pass through properly.

    Which is why I recommended Project EYERay. It's a merchant resource.

    OK, bought it... I'll at least load up the settings and see if I can figure out what she did to get that nice blend.  Thanks ChanglingChick for your persistence.  :-)

    That is what I would do :D

    @ramwolff  Good luck with your character. I'm really liking the eyebrows!

  • RAMWolffRAMWolff Posts: 10,212

    Thanks folks.  With all the crap that ensued with the new computer that set me back I'm really slow going getting my muse fired up again.  I hope to have him released ASAP but that might still be a while!  LOL  He's done really but I had issues with the underarm hair so that got nixed and replaced with a nice mustache I made a while back (so he's got a Porn Stache as part of the package now lol)  The eyebrows were completly home grown in ZBrush, he's got scruff and pubic hair as well.  I have other hairy bits but will work on perfecting them before I release those (for another pack at some point).  Fiber hair looks really great but it's a total bitch to get just right.

    Fiber mesh is also a huge eater of resources, I try to avoid ist when I#m not super close to the figure with my cam

    There are a couple of mapped face options, one with eyebrows and the other with eyebrows and scruff... I HATE LIE so won't even try to make settings for that slow as mud option for DS!  LOL
