Hi,
im trying to make a simple puzzle game.
The puzzle is a big image, and im using it as a texture.
I made a box tile model (puzzle piece), so it can show a small part of the big image (it has been placed as the skin of the box).
My idea was to create many tiles, and then displace the texture or the UV coordinates for every tile model, so each model shows a part of the complete image.
(Then the player can touch and move the tiles, well, you know)

Im not sure how to change the UV mapping of each tile model (it seems im changing the UV coordinates of ALL models at the same time),
how can i do this? is there a better way (i.e: cutting the bitmap image on many squares, and then assign each to one model, or others ideas)?

Thanks!
