    As Deadalus51 mentioned... the most interesting part of the character right now are the eyes.. i worked a lot on the eye shader and there are still some stuff missing i want to implement

    I will just show you some screens and try to explain it.

    So the first thing is that the "eye" mesh consists of 2 meshes. One is a simple sphere and the other an "eye overlay" mesh hovering over the sphere where i projected the occlusion so we have a decent shadow for the eye socket.
    Notice on the first screen there is a waterline at the bottom of the eye? Instead of making another mesh for it, i can control how strong the refraction and the specular are on the "eye overlay" mesh. I also added a normal map to boost the refraction.




    The sphere itself has an input of 3 normal maps. The Cornea Normal where you can fake the cornea popping out. The second normal map input is for the Iris, it's just a nice little detail so the highlights will have a nicer spread. The last normal map input is a detail normal map for the eye ball so we don't have a flat highlight on the eye sclera. I also added a Bump Offset to enhance the parallax effect of the cornea.




    Deadalus51 also mentioned that in many videogames there is often a cubemap faked in the shader itself... we threw that out since we wanted to avoid the eyes being really bright in the dark. We also went for the clear coat approach for the sphere mesh which works pretty well. In the eyeshader you can also change 2 colors as seen in the screen below. I am also able to set how strong they blend into each other.





    Lastly here is a comparison screen.




    If you have any other questions on how i approached things feel free to ask me/us! We are happy to answer them all. In case you want to see the Material... I just want to say that we want to bring the whole scene to the marketplace
    Cheers!!

    So, I havent yet had the chance to get my hands on the scene (since we are still working on a way to get nice source control to make sure everyone from the team can sync and submit stuff easily), however lenz was so kind to give me a quick flythrough and also told me how he already achieved certain things. So I can at least just share some basics with you^^

    Regarding the character, its actually not that technical, because its "just" (höhö) some very good character work getting the last finish by a now very nicely working skin shading model So first of all, kudos to Bao for such an amazing model! Second...big thanks to the guys at Epic (points at Martin Mittring) for making Jorge Jimenez´fantastic research work on Screen Space Subsurface Scattering a part of Unreal Engine!

    Interesting thing about the character in its current state: the eyes are probably not shaded in the way that comes to your mind first To explain you a bit my thinking when I tackle materials and surfaces, I always try to start in finding out how the object is made in real life, which parts contribute to how it looks and what environmental circumstances further modify the look of things. I then try to find ways to mimic the observed behavior as close as possible. But sometimes, you start to realize that even if something should be like this or that...it still makes sense to not do it like that, because this effect is so rarely visible, that another effect that happens more often has the greater impact.

    So, normaly eyes are made of organic, slightly translucent matter that reacts to light. So the first guess would be yeah...use sub surface scattering. This works nice and also does not look too bad. However, the eyes are always so small on screen and light has to hit it in a very specific way (eyes are also quite protected from the surrounding bones and skin tissue) to make the transmission or scattering visible, that it didnt feel appealing to me.

    Also, you have very complex reflections on the eyes (which get faked often in video games) due to tha fact that the eye is actually a multilayered surface with different characteristics for each layer.

    This made us try out the monte carlo clear coat shading model for the eyes which, in my opinion, gives us very neat and fully dynamic results without the need to fake any kind of lighting on the eye (not breaking pbr )

    I would like Bao to talk about the rest of stuff going on with the head since he built all of that stuff (I just helped with feedback on the shaders and lighting), but there is definitely some cool stuff going on

    So, to quickly just give some specs of the scene:
    • It is fully dynamically lit right now and the intention is to keep it like that
    • It uses a movable skylight and DFAO, the raytraced shadows are something that I will introduce as soon as I can sync the project^^
    • Right now it uses some fill lights. I want to change that, but if the artistic vision gets lost in the process, we might stick to a couple of them for the finished scene (push min roughness to get rid of point light reflections!!^^)


    Yeah...thats all I know so far

    Hope it gave you some insights and cheers!

Since i don't want to create a new thread i will hijack this one... guess it shouldn't be a problem since we are doing a collab Just wanted to say that Sarah.Mai and Deadalus will also join on this and I guess they might post some screens in this thread too. Really loving the new subsurface profile! WIP though

    just....wow!

    Now thats what I am taling about! Awesome improvements man. Yeah...we still gotta figure out the source control stuff (so any tips are greatly appreciated^^) but this will get niiiice ^__^
