Meet the Engineer Prototypation Character
I choose my reference character to be 3 head tall and sized as 2 vertical grid cells. It have to be able to jump / climb / vault over 1 grid cell sized obstacles.
The character I have In mind was a building site worker.I downloaded a really well made model of the tf2 engineer from Tommy Tallian collection of low poly tf2 characters http://tommytallian.blogspot.it/p/low-poly-tf2.html.
I had to made it 3 heads tall then rigged and skinned it with bones to animate it.So say welcome to the "Midget Engineer".
The model is very low poly(around 400 poly) with a really small and optimized texture.
Those are more Nintendo Ds ish kind of specs for a 3d model, but it doesn't matter for a prototypation model.
Plus i can subdivide it few times to generate some kind of fake lods to test on devices different polygonal budgets
