Chapter 9. Texture Painting > Texture Bit Depth and Page Size

Texture Bit Depth and Page Size

Texture memory is an important factor in game development. Keep your pages as small as possible—the image size as well as the file size is important. Although you may have been given a maximum texture limit, you’ll get extra points if your character could look just as good in less.

There are two ways you can do this: reducing the actual page size, and reducing the bit depth. You can even combine reductions in both to get texture sizes down even more.

How far you can go with these reductions (or whether you can use them at all) depends on your managers and the game you are developing, so always check this out with your team. If you can, try and see both versions of the character—reduced and not reduced—running in the game engine, to get a realistic idea of how they will look. Remember that things look completely different on a television screen than they do on a computer monitor, so it may be that you can’t see any difference in the reduced version. In that case, you have saved some memory that can be used to polish the game elsewhere.
