If anybody wants the model, you can download the .FBX and Textures at this link. I packaged it specially for Unity, but if you want to use it in something else just grab the Spec Map out of the Alpha channel of the diffuse map.:

I really wanted to make this mech look like he was made of different types of metal. A shiny chrome for the joints, a dull flat iron for some of the inner parts, etc. To achieve that I made some sharp differences in my spec map. Because my UV Islands were pretty clean, I was able to get most of this done in photoshop.

Here is the final result, with the spec map below so you can see how I got it to look like that. You can really see the sharp constrasts in lightness and darkness on the map creating the illusion of different materials used in the model.

So when I finished my 10 million poly super high poly model, I decimated it down with zRemesher and then split it in half.

Since he is symmetrical I will get twice the resolution from the texture map by splitting him. It also makes optimizing much easier because you only have half the model to work with. I deleted a bunch of edge loops to get the polycount down further to game level. And ended up with a model that looks like this:

For the Unwrap, I wanted to keep my UV islands closely following the geometry of the original model. This should be a lot easier to fix when I start cleaning it up in Photoshop.

Here is my final UV Layout:

And here is what the low poly model looks like now with the first bake out of my maps before cleanup.

This is something I have been working on using hard surface modelling techniques. It is both my first character from absolute scratch, and first time making a hard surface model in Z – Brush. For a first model he looks OK, but the whole flow of the character isn’t there. If I ever get a chance to live my life over, I would have spent more time concepting him out and less time doing.
