Old man: A "realistic" approach to real-time rendering.
polycounter lvl 4
I´ve finished this model few months ago but i wanted to do an overhaul when i´ll upgrade my computer...and nowadays i have the same one so...
At the beginning i was focused only in achieve as much detail as my pc can, but i ended using a quick lowpoly version and -Transfer Atributes-UV. This is why my wireframe is not smoothed and messy in some parts where the original cuts where made.
It was my best effort to do a real-time portrait without referencing anyone in particular and with a huge effort in asymmetric forms. Unfortunately, i was using the old PBR workflow Spec/Gloss with cavity maps instead of the new workflow focused in detail maps/smear maps and much lower resolution as said by Adelle Bueno in GDC 2017: https://www.gdcvault.com/play/1024410/Achieving-High-Quality-Low-Cost
As typical i have a lot of critics to myself:
-Don´t focus on my own limited knowledge of anatomy, use always references.
-Don´t do a messy low-poly version "after" finishing the original/Zremeshed one.
-Don´t do huge and big tertiary details and use detail tiling maps for microdetails to break the forms and make pores much smaller and realistic.
-Usage of another engine with more capabilites of layering amd mixing textures, especially for combine detail normals.
-Use a much higher degree of SSS and improve eye shading and blending.
-Improve in some way, the shelf shadowing of hair cards, either by light baking or by shadow casting.

So I guess it's not completely unrealistic, although the OP can mention if it's intentional or not.
Pictured: Oldest woman Jeanne Calment at age 121.
In general age progression widens the face especially in the area of the jaw due to flaccidity and a huge sag effect in some areas:
I didn´t consider it even a good reference, the photo is tilted a little bit, B&W, super focused on the little/tertiary details, it´s almost a macro of this old man that i don´t know who is...
And this reference don´t tell me enough information to fill side views, back views, hair, clothes and so.
Only tells me, huge nose, huge ears, pretty wide jaw(it´s a macro portrait so it´s common) slighty smaller eyes in comparison to the general rule and... some white hairs.
As i wanted to do an old type of human, focused mostly on asymetry with kind of "Warm", but "Sad" feeling i choose that as the main idea.
