Ogl Y Multitexturas

[vicho]

 hola les cuento tengo el siguiente problema al tratar de usar la multitextura, logro renderizar una vez solamente un poligono con multitextura, al segundo renderizado me renderiza el poligono en blanco

ahi esta el codigo

aparece una funcion GenTexture
por el uso que le doy es casi obvio lo que hace
si alguien sabe cual es el problema que me diga por favor

 y el cacho es de windows, la cosa pa rara, por que hago lo mismo con linux y anda bien
