Polycounts, what are static meshes and what are made in Radiant

[WideBoy]

Ive been hunting the internett for quite some time now, and you guys are my last hope.

Where do I find the polycounts for custom models for COD4. (Buildings, Weaponds and props).

Are buildings in the game static meshes or are they buildt in Radiant, if they are meshes, where do i find them in radiant?

I realy hope i can use Static Meshes as buildings and props, much easyer and faster to create good looking buildings with Maya then with Radiant.

So could anyone shed some light on this issue for me? or point me in the diraction of a forum where theese answers are flowing like wine?
