Minimum Texture Size

[Vinz]

Is there a minimum, or do they just have to be even numbers? Ex. 32x32; 64x64; 128x128, etc.

There are 3 possible physical limits, depending on how pedantic the game is.
1*1 as that corresponds to the lowest mipmap a shader can use.
8*8 as that is the smallest JPEG compressed block one can do (there is no space saved going smaller).
32*32 as that is the smallest JPEG compressed block with downsized colour space that one can use (there is no space saved going smaller).
I do know that WC3 does have some multiple of 2 limit enforced on textures, however I am not sure if it can go down to 1 or will be stuck at 32 ish for other reasons.

512x512 is the max right?

For some reason warcraft 3 uses only 512x512 even if the texture is larger, e.g 1024x1024 it will still use no more than 512x512.

Thanks for the info.

Might have something to do with the limits of Direct3D 8. All the massive textures we are used to have only come more recently.
