hi @ll ! i wrote a little program with a main.cpp where i created some textures in an array (with glGenTextures).. these textures run without a problem now i created an object (shall be a 3d-object) wich (in its constructor) creates some more textures (which are only for this object-instance, and so isn''t needed in the main-prog) with glGenTextures. but when i try to paint the 3d-object, it''s totally white. i controlled the texture array (from glGenTextures(1, &textur[0]) with a debugger and i found out : all fields in the array are "0" .... why is that so ?? in some way glGenTextures desnt run well ... but what did i do wrong ? the images are loaded and eve3rything shall be fine ... please help me !!! thank u ! nebular
