Just another texture/generator I made before put to use - they are interchangeable. For example the Scorpion (by scorpio) shows the desert-camo-texture. And this model shows urban/sea-camo with randomly blended in rust. It would likewise work with desert-camo and dust or desert-camo and blank-metal. This one just looks better/more detailed than desert-camo. Besides having a more complex model makes the automatic texturing look even better. On my original simple blocky model it doesn't nearly look as good. The generator is only limited by pre-calculation time and texture memory at this point - and you need to be able to compose textures. It is important to have a look outside the (game) programming pond - lots to find in the artistic domain.
What I mentioned before was the probable possibility to use 2d-textures to blend over materials eg from camo to steel/rust to give more control to the model artist (you don't need to be an texture artist). Eg to make edges more shiny, change material half way or let rust accumulate in crevices
. But that's future - no promises - it would assume a transition to shaders eventually.
The next step would be to support different materials on a model at all I guess.
