Nu kaa tad tu to dari?

Code:


(pienjemot ka pashlaik aktiivs GL_TEXTURE0_ARB un tajaa ir iesleegts GL_TEXTURE_2D)

glBindTexture(GL_TEXTURE_2D,Ground);
glActiveTextureARB(GL_TEXTURE1_ARB);
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D,Detail);
glActiveTextureARB(GL_TEXTURE2_ARB);
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D,Light);


un visam buutu jaaiet. Varbuut aizmirsi treshajai textuurai glEnable(GL_TEXTURE_2D); ?

Edit: Hmm, kas taa par karti, kas atbalsta 8 textuuras, un kaa vinja to dara? Parasti sastopamais variants ir 4 textuuras fixed pipeline un 16 shaderiem. (Laigan ja sheideriem izmanto virs 4 par labu fps var aizmirst...)
