I quite liked the way I could massively expand my Alleys Pack by adding more textures and a bmp file whilst reusing the original mesh. This seems a great way to give the game designer a lot more options with relatively little additional work by the artist. Of course it depends on some nifty mesh and texture designs in the first place to allow for additional textures to look correct, but that's part of the fun. Sp I have extended this idea to my latest model and may well do this quite often in the future.
I have uploaded a set of three bunkers. They come as a single download but the purchases will find three rather than one model available to them. The bunkers are themed for different war theatres being:
A camouflaged Normandy type
A camouflaged El Alamein type
A generic rusty concrete type
All can be entered by both the player and AIs and use just the one low poly count mesh.
