How to Train 3D??

its simple for me
i choose something that i know is complex and challenging like a gun or a car and i simply model it, sometimes i run into problems and deduct certain features in the model but it makes me works faster and discover new things.

modeling is games is different, its an artistic job and technical. you can't model all the parts of a gun if its 200k polygons, you need to use normal maps and such. every piece you create you have to make sure the UV's are right and the texture are in the right size and its according the polygon budget you have.
if you want to make models for games i recommend you to look at environment modeling for games by gnomon (is a paid dvd)

this is also a good example of how workflow is being used in games

this is essential as well

Keep in mind that big 3D productions are always in a team. You're talking about pro's like they can do everything but those pro's are probably only good at a handful of things.
If you want to become pro you should specialise in a certain CG area so that you can justify getting paid for a role in a big production.
