Time ago i riped some game models in the search of alternatives to fast prototyping (in order to save time).
At the end i decided not to use riped models due to lack of quality of the models (very low poly and textures very small)

But having advanced very little in this two months of the year (currently working on this project in my free time) I am considering using some models with some type of improvement in its textures, making normals, heights, AO out of the diffuse ones; this is the result.

I wish I could make quality models, but to achieve this goal, it is necessary to invest time (Sculpt or modeling high poly, then the need to do retopology, uv unwrapping and texturing). But since Time is equal to money. This is the perfect alternative.
