Hi, i've implemented one of the effects from the 'effectsTest' sample, and was wondering if there was away to make the grid transparent so that I can see the layers behind it. Currently the grid is the size of the whole iPhone display and transforms with my sprite. What I want is to just see my sprite not the entire grid. I have a feeling that i'll have to mess around with the opengl draw code but I don't really know open gl... any help would be appreciated! thanks!

nevermind figured it out, just had to make a call to glColor4f() and change the alpha value to 0!

I am not sure what you are trying to achieve and I am also not sure what I am talking about, but maybe if you just want the grid lines you could draw line stripes instead of triangles in OpenGL.
