Default Re: Texture of Objects

Texture maps can be any number of pixels you want, there is no set size. However, square power-of-two (1x1, 2x2, 4x4, 8x8.... 256x256, 512x512, etc.) maps usually render quickest, or may be required if you are planning to use your model in a game.

The general rule-of-thumb is to choose your texture size based on how big the object will be in your final render. So, if the final picture you want to render is 1024x768 and your cube takes up about a quarter of the screen, you'll want to use a 512-pixel map. If the cube takes up the whole screen, you'll want a 1024-pixel map, and so on. The idea is to pick a texture size large enough that it won't stretch or blur in your final image, without making it any larger than it needs to be and slowing down the render.
