I'm pretty new at modeling, i've done few models and compiled them to Source. Now i'm modeling a bus with inside parts and such. I'd like it to have the best looking breakable windows that is possible to create. I believe the basic breakable window made with brushes is the best choice (?).
Anyway, my question is, what is the best way to do those windows? Should i leave window-parts blank and fill them with brush based windows? Should i model the windows as a separate model and can i create as good glass material as what you can do with brushes?
Bus is going to be just a static model (apart from the windows).
EDIT: Oh, forgot to mention that i'd like those windows to be a little rounded, but that's not necessary.
