This is not a complaint and I plan on asking further requests in the aha forum.
A point of clarification, the reason this request is related to the request for not doing a pre-draw for 3D, is that this light effect will only work if 3D is not pre-drawn and a user effect can be the first shader used (lighting in this case, including in the shader the needed depth assignment regarding transparency and color/opacity changes).
I understand it did not work out in the way Scirra tested this.
