PS that second image is so much better, nice. smile

Why thank you.

But you’ll never guess what… I carefull applied all your settings and have only just realised that I forgot to switch “Subsurface Active” to ON !!

Duhh!!

So here’s what it should look like (though there’s hardly any difference in the skin it seems whether SSS is on or off)

Final question then. We’ve done the UberSurface settings for all the skin and eyes. what about hair, eyelashes, eyebrows, nails and teeth. Should I do those too?

I haven’t gotten around to hair yet so I cheat with Uber Hair. wink

Teetth Apart form the IOR all the rest is guess work for me.
I used an IOR of 1.70, SSS scale 0.20 plugged the bumop map in to the SSS Strength to give a little variation. Scatter color off white, absorption colour light grey Diffuse colour I made a off white too.

Nails I think have an IOR of 1.54, but do they have SSS I am not sure. I have got aound to finding out about nails yet either.


If you try what I said in my last about removing the texture maps and testing each channel then you will see the SSS effect of not…then you can adjust but it should be subtle.

Thanks again. Don’t get me wrong. I am VERY happy with the results of all these tweakings. Subtle is good. It’s the diff between good and excellent smile

Just one check regarding your post yesterday. You said this

Also there have been a few threads lately about SSS Scale and Shading Rates and I have tested them and they do work.

SSS Scale 0.10
SSS Shading rate 1 or 2. Higher SSS shading rates or for Translucent materials like thin things like paper etc.

Are you modifying your earlier advice about SS scale then? (as you originally said 1 to 1.7 for skin). Or were you meaning for eyes?

Yep I am modifing my advice with what I have learnt recently. 1.7 and 1 equates to 1.7 and 1 cm respectively, pretty thick skin. smile I didn’t realise or think of what these values were/are, and given the default Daz Studio measurement is CM it sort of makes sense.

actually I have only just realised that V5 (out of the box) has the UberSurface shader and has all the SSS settings already set. Here’s how she looks with the same lighting set up as I have been using so far for Dana. Pretty nice, I think.

That’s interesting, and good results for the most part. One thing I noticed though is she’s reflecting her own eyelashes.

Just because I may have a strong opinion doesn’t make it any more (or less) correct than any other, just that I feel passionately a particular way at that moment.

Yeah lower the reflection strength on the eyes more but yes not bad at all.

One thing about all this that I keep repeating….the whole thing is a cheat, what matters is the end result how we get there is a matter of choice. If you are happy with the results then that is all the matters.

Can I get an amen wink

The thing is, we want to be aware as much as possible how it ‘should’ work, because if something gets ‘fixed’ later in the base product it gives us a heads up on what we would probably want to do to adjust our settings to the new fixed ones to get them to work. It also gives us a heads up on how to fudge things in related but different circumstances, and what might or might not carry over to a different environment. And last but not least, it gives us a good central point to start from. But, if it gets too confusing and it works, don’t worry about it till then is my take. Usually things sort themselves out eventually.

That is what is so nice about what Szark (and others) are doing when they work through these settings. They have all of these things in mind when they are working on what the best settings are from their experiments as a core to work from, thank you Szark and everyone else who spends time doing this smile

That’s strange because reflection is switched off on all her eye surfaces!! How are they reflecting then??

Yes actually I had already come to that same conclusion (that it might actually be a shadow.) Someone else posted a picture with the same effect that made me think of it, don’t remember exactly where I saw it now though. Try turning off cast shadows on the eyelashes.

the eyelashes don’t appear as an item in the scene tab so I can’t turn off cast shadows. There’s no shadows option in the shader tab either.

Hmm, sorry don’t know… would have to set up a test scenario and play with it. I’m off on other projects atm though :/
