In order to achieve the specific style of the concept  that uses old junkyard pieces as building blocks,

I used several parts from different 3d library models and assembled them together to construct my concept ship.

I hope to be able to texture it as soon as I have more free time.

My aim is to complete the whole workflow, from a high poly assembly to get normal and cavity maps from, to retopologize a low poly mesh and finally to produce a fully textured realtime version of the bust with a polygon count under 5k triangles.

I got the idea for the bust from a creature head I had worked on, some time ago.

An initial 3d concept that did not make it to the end, but helped me to define the final concept..

 The final 3d model of the bust, still with simple materials and no battle weathering

I like to render my models as if they were 3d prints – since real 3d prints are still rather pricey -

and this mecha dude is not an exception

These shots are my work so far, heavy battle weathering on the metallic and rubber surfaces of the armour.

Possibly I got too far, but it was a useful exercise for detailing anyway.

Thank you Mike!

They are compatible with ZBrush 3.5 and up.
You can download the materials in the Freebies section.

with the settings, I was able to get a shader compound that gives a “dirty AO look” on a geometry.

It is preferable for the geometry to already have UV coordinates, but the compound can work

nicely on a non UV mapped object too.

You can take a look at the compound’s tree and also 2 samples of its usage, on a UV mapped

(house) and a non UV mapped geometry (hoplite character), below.
