...still didn't understand how to use that shader. I've exported a Poser-character as an OBJ-file and imported the mesh into Octane 2.06 (standalone), After that I plugged the texture file of the character into the "colour-slot" of the node and the "normal-map" (used "shader map" to create them) - but whenever I try to render the mesh I get horrible dark skin (path tracking mode) - so what do I have to do to get a natural looking skin using R20?

thank you

Hi MyRho,

I just used the "Tonysculptor Skin R20". I am getting really good results but you still need to tweak it. The way I am using it is I connect the "Tonysculptor Skin R20" to the imported object and then attach the texture / bump as needed to it. I am attaching a partial screen shot to show how I have it connected.

When I started with it today, I was doing it all wrong and had it connected to a mixed material node with one side connected to the"Tonysculptor Skin R20" and the other to the texture. The result was pretty bad. Finally figured out that you need to connect the texture to the "Tonysculptor Skin R20" and it to the object and immediately it made a huge difference.

Hope this helps if you haven't already figured it out. Just playing with the standalone version until the Daz plugin gets fixed.

Cheers,
Rajib

Hi All,

Some of you had asked if I could share what I did with the "Tonysculptor Skin R20".

I am attaching what I was able to do. Still a work in progress. I only like the lips and how the teeth looks. Not happy with the eyes at all. The skin, hmmmmmm.... not very sure if I like it or not...

I have done this in the Standalone version. Unable to get anything near this in the DAZ Studio plugin. In fact looks horrible and too translucent even though the nodes and values to me are the same. Going to try it in the plugin again.

But this is no where near what Tonysculptor has done. I think the base texture does make a fair bit of difference. Will post again if I am able to make it better.

In any case, thanks Tonysculptor for sharing it with the rest of us.

Thank you... but for me even that doesn't work.
I've tried several textures/bums/speculars/normals, using exactly the cofiguration shown in your sceenshots but even then I get horrible results (see attached screenshot)
There are big dark areas on some areas of the body. And I just don't know why the skin-shaders work for you and not for me...
See? The neck and the head-area (back of her head) are very dark (I didn't apply the shader to the limbs)

Are you using direct lighting ? You may need to use PMC or PT. My scene is lit by daylight. I will try with a light emitter like your scene and see what I get. Will share the result. Also try the "scatter scale" settings. It might help. One other thing, check the skin texture power. You can increase it if it is not at its max.

ppphhhhh.... I tried this for WEEKS now. Kernel is set to PMC or PT, but I still get very ugly results. Looks like wax or something but not like skin.
It's getting a little bit better if I try to set the SCATTER SCALE I to 4.000 an II to 1.000. But I'll have to lower the gamma of the skin-texture from 2.2 to 1.0. After all I have NO IDEA why this doesn't work for me because I did EVERYTHING exactly as you showed in the screenshots.
I would be happy if anyone could help me with that.

I think Tonysculptor's model scale is huge or something. I tried his shader but I never managed to make it look like his examples.
But it doesn't really matter, because I made my own. ;)

Scale makes a huge difference. Tony's works out of the box on real life scale (as far as I understand it) so if your model is not real life scale then you need to change various different parameters to fit your model's scale.

e.g. if the scatter is high and your model is small then you will see a kind of waxy translucent effect.
If the scatter is low and the model is large I'm not sure what artifacts you might see but likely you won't see *any* SSS at all.

Very nice, Tony.
Good work.

Could you post your shader tree ?
