In my Game Design class we have been collaborating to make a game called "Cthulhu Cop". I have been making animations and textures for the project. Here is a picture of a sign I textured for both high and low quality that shows how many faces the objects are made of. The model was made by Jacob Augenstein and the original concept design was made by Matt Wydick. You should check out their sites! I created the textures by sculpting and painting the original models in Mudbox. I mapped out the UVs in Maya, exported the texture maps from Mudbox and applied them to the lower res versions in Maya. It is important for game elements to be as simple as possible in order for the game to run smoothly. Textures help the game look nice, while not eating up memory.
