 Posted: Wed Oct 05, 2005 1:34 am Post subject: Wide textures |
 |
|
| I am converting a game that runs on PS2 and DirectX just fine and am having trouble with getting a 1024x256 T8 working. All other textures are working so I am wondering if there is an internal limitation on width. Does anyone know? |

| There are only 8 mipmap levels, which suggests the max texture size is 256x256. |

The max size is actually 512x512, despite the 8 mipmap levels. The mipmaps don't go all the way down to 1x1 in that case, it stops at 2x2 :)

Well, you can't specify a ninth mipmap level so you simply can't go down to 1x1 on 512x512 textures. Unless you can abuse the mipmap size parameters and have the last two being 4x4 and 1x1 .. dunno if that'd be much use though.
