SDL/OpenGL - změna barev při texturování – C / C++ – Fórum – Programujte.com

Při načtení textury se mě změní barvy původních oběktů (bez textur) ve scéně. Barvy ztmavnou, modrá zčerná... (Světla nemám povolená, tam chyba nebude...)
čím to může být?
Děkuji

Mozno by pomohol nejaky ten kusok kodu ...

No je to uz nejaka doba co som videl OGL naposledy, ale ked si dobre spominam tak, ked chces pouzit texturu tak o tom musis dat OGLku vediet funkciou glBindTexture, ty ju sice volas ale hned pri nahrani textury to znamena, ze sa snazi namapovat na vsetky objekty a kedze nie vsade urcujes ako sa ma mapovat (funckia glTexCoord) tak to potom moze sposobyt nieco take. Cize bind daj aj pred vykreslenim objektu na, ktory chces texturu vykreslit a predtym ako zacnes vykreslovat objekt bez textury musis bindnut defaultnu texturu (predanim NULL namiesto idcka textury).

Děkuji!!! Problém vyřešen
