Nice addition. I guess it would be even more useful if you try to translate some stuff into english, otherwise it's pretty hard to reuse it.

[link3rn3l]

is simply use..!!!


LOAD_Q3SHADERS("quake3.bsp", myIMetaTriangleSelector , myISceneManager)


or



LOAD_Q3SHADERS("quake3.bsp", NULL , myISceneManager)

Ha-ha! I tried at least 10 times downloading it. Furfile. It starts dowloading with about 5kb/sec and freezes after an hour of downloading somewhere 70percent download. How about another mirror in Filebeam or Rapidshare?
