Well..
I wanted to make this post specifically for the texturing process i am going through for the Zombie thrashing truck i have been working on with other projects (which you can see briefly in the post THE MACHINE).
using the perks of amazing high poly sculpting in zbrush,
I started by importing the different low poly meshes from maya
2nd step was sculpting the scratches and major deformed parts like the metal in front
and then after giving the basic first layer of colour using polypaint started the process of taking and making different images for specific uses under spotlight
I wanted the truck to have the colour tone of the 11 striped ball to give it the appeal of a rough enthusiastic fun loving trucker in an apoclyptic world.
Similarly for the wheels i used a couple of scratched aluminium and rusted metal textures
For the rusted leaking parts on the door and other metal frames..
i used a similar texture and painted wherever i wanted the rust leaks to be
