suggestions for tower modeling
I am currently modeling a little tower (see the pic). Now since the stones are quite large, I think I need to model them directly, since they will affect the silhouette, and so a bump map is not appropriate (though I will be using it for the fine detail) Now you can see the geometry there - that is a polygon model by the way - with the rough map of where I want the stones to be in the texture. Could anyone suggest how I might cut and model the stones to give them a rough shape over which I will later bump map - which tools to use and so on?
edit to add: if building the polygon model and then altering it is a terrible plan, then feel free to say, I don't mind remodelling the whole thing, it only took me about 10 minutes to do that.
