Looking great johnas. I finished the lowpoly trailer today, gotta model the highpoly of that next.
@floriversal: It might sound more complicated than it actually is. Basically, details of the highpoly model get "baked" into a texture map, the normalmap. You only have to apply the normal to the lowpoly and you get a more detailed look.
Heres an old comparison of the highpoly, lowpoly and lowpoly with normalmap of a g36c I did a while back.
Yeah of course, every nextgen game that supports normalmaps. Which means pretty much every game released for Xbox360,PC and PS3 in the last 6 years or so.
Im not sure when they started to use normalmaps in Need for Speed, I think Pro Street. Mafia 1 doesnt support them, Mafia2 should. IV and newer GTA games do.
btw, the final result of that rifle mentioned above with normal, spec and diffuse maps looks like the pic attached. You can use the same texture maps for a truck or car as well. They help you to get tons of detail into your model without the need to spend thousand or hundrets of thousands of additional polygons.
