This is the concept to start working. An old cowboy.
Here's a profile design...
...and some photo reference to start with the idea.
I will upload a 3/4 view and a full body design ref also.
I work with 3dsmax to create the 3D character but the technique can be followed with any 3d software.
I recommend the open software Blender it's free and a very good tool.
This is what I will show:
-Shortkeys and technique.
-Head modeling and topology.
-Body modeling and topology.
-Modeling complements, as cloth or hard surface objects.
-How to map a character and its objects.
-How to avoid texture distortion with check maps.
-How to paint skin for face texture from scratch.
Lighting and rendering.
-Shaders with basic light studio render.
-How to create realistic hair in 3D.
I hope you enjoy following the updates and maybe learn something interesting.
