Stylized sculpt and PBR textures + hand-paint.
This is one of my practical works dedicated to Wayfinder.
I create all my models using my usual workflow:
First, I create the basic shapes in Blender. Then I use Zbrush to refine the shapes and give them their final look. Retopology in Topogun 3 and UV unwrapping in Blender. For texturing, I use Substance Painter to create the tonal and color foundation. Then I switch to 3DCoat for hand painting and finishing touches.
