Does anyone know if there is a cheat or a hack that allows you to change the houses in the lot and houses bin into beach lots? I have alot of great houses that would look great as a beach house, but when I place them at the waters edge, I don't have a beach! Please tell me there is a way to change them.

Hi, could someone please tell me how to recolor custom content. I have SimPe and Gimp. A link to a tutorial would be great.
Thanks!
