Hi there, first post, be kind. I have an idea for a Payload map, which would involve something very different to a Bomb cart being moved along. The gameplay is the same idea as Valve have said they're planning; the attacking team standing on the payload cart as they go. I know what I want the model to be like, but is it necessary to use a model, or is there a way of simply using brushes (it's very simple geometrically)? If only models can be used, is it possible to export a bunch of brushes from hammer as a model, then import it as a model?
