Bij Beyond 3D is een speciaal Quake3 level verschenen die gebruik maakt van 4-layer multitexturing. Het level is gemaakt door ST Microelectronics om te laten zien wat de Kyro (II) chip kan. De Kyro chip is namelijk de enige die 4 textures zonder problemen in één pass kan verwerken. De download bestaat uit een level plus een demo met een batch file om deze te draaien:
What we have here is a map that features 4 layers of textures.
Such a map is possible with games being developed now (although we can't be sure) and it provides for very impressive lighting and shadowing in textures. Imagine adding additional layers for bump/detail texture, specular, reflection map and layered fog/haze. That's scrumpilicious (new word by Reverend!).
[...] Why hasn't it been done before? Several reasons. First, most graphics cards are only capable of doing one or two textures in a single pass. Additional textures require multiple passes and thus offer a considerably negative impact on performance. Additionally, with a 16-bit image, multi-pass texturing can offer serious rendering issues such as banding (as can be noted on many cards in Quake III's sky).
