I have some stock models that I'd like to insert a lightbar and few extra lights to make them police models. Can somebody tell me what I need and how the hell I do it?

Thanks.

Zmodeler, and google to search for guides on how to model, map els, and texture. Youtube has some good tutorials about ELS and texturing. Modeling is not something someone can explain over a forum post. Its hard and takes time. You can download some lightbars and certain police parts but you'll have to google that to.
