Try changing

GLuint * textures;

into

GLuint * textures[2];

It''s early and that''s all I can think of, maybe later I can think more clearly.

Later,

nope, that isn''t it... It works now, I just don''t use the pointer anymore...

Thanx anyways, Marty

Should GL_TEXTURE_COORD_ARRAY''s be in the same order as the vertexes of the indexes, when I use glDrawElements? My program gives acces violation, so I guess it''s the number of indexes... When i divide the number by 2, it doesn''t give an error (because it doesn''t go out of range for all the arrays), but it shows only some pixels of texture... What''s wrong? I''ll try the index numbers next, i''ll post when the problem is fixed.
