Hello, I got this code that draws a textured wall of a brick house glBegin(GL_QUADS); glTexCoord2f(0.0, 1.0); glVertex3f(x,y,z); // TL glTexCoord2f(0.0, 0.0); glVertex3f(x,y,z); // BL glTexCoord2f(1.0, 0.0); glVertex3f(x,y,z); // BR glTexCoord2f(1.0, 1.0); glVertex3f(x,y,z); // TR glEnd(); If I want to put a window or door in that wall defined by GL_QUADS, what woudl be the best way to do it. Another GL_QUADS,glScissor, or alpha testing? Thanks

if you just doing a textured quad, I would recomment just having the texture have the window or door draw into it..
