glActiveTextureARB(GL_TEXTURE1_ARB);			
glTexEnvi(GL_TEXTURE_ENV,GL_TEXTURE_ENV_MODE,GL_COMBINE_ARB);
glTexEnvi(GL_TEXTURE_ENV,GL_SOURCE0_RGB_ARB,GL_PREVIOUS_ARB);
glTexEnvi(GL_TEXTURE_ENV,GL_SOURCE1_RGB_ARB,GL_TEXTURE);
glTexEnvi(GL_TEXTURE_ENV,GL_OPERAND0_RGB_ARB,GL_SRC_COLOR);
glTexEnvi(GL_TEXTURE_ENV,GL_OPERAND1_RGB_ARB,GL_SRC_COLOR);		
glTexEnvi(GL_TEXTURE_ENV,GL_COMBINE_RGB_ARB,GL_REPLACE);

with this code i want only the texture on GL_TEXTURE0_ARB to be shown,but it doesn''t work, does anyone know why ? ps:i know that i can have this easier ,but it want to use the extension.
