ARGGGGHHHH, i need expertise of the gamedev forums here! I am loading my and binding textures like this: AUX_RGBImageRec *fab; fab = auxDIBImageLoad("crap.bmp"); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D,0); glTexImage2D(GL_TEXTURE_2D,0,3,fab->sizeX,fab->sizeY,0,GL_RGB,GL_UNSIGNED_BYTE,fab->data); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR); glTexParameterf( GL_TEXTURE_2D, GL_TEXTURE_WRAP_S,GL_CLAMP ); glTexParameterf( GL_TEXTURE_2D, GL_TEXTURE_WRAP_T,GL_CLAMP ); which works fine, but when i have more that one texture (ie/ i load a texture and bind it as texture #1) then only last texture loaded actually works (ie/ texture #0 displays the OTHER texture)...... what gives?

I already am using glBindTexture(GL_TEXTURE_2D,texID) for my drawing code, the tex coords are fine... but the last texture loaded is the only one displayed, REGUARDLESS of the texture id i bind before it draw :\

in which case you must be loading any new textures into the old texture ID

Most likely.

Muncher: You need to generate a unique texture ID for every texture you try to bind. glGenTextures() will fill an array with unique texture IDs that are ready for use. You can setup an array with as many unsigned ints as you have textures and pass it to this function. Then, assign one texture to each ID in the array.
