So I am making a little platformer with my nephew (trying to get him into programming; he seems to have a liking for it.) And I am using shaders and surfaces within a single room at the moment, but I am noticing that the shader seems to also affect the surface making for some let's just say undesirable results. Is there any way to make a shader ignore a certain surface before drawing out across the screen? If any more information is needed to answer this just let me know! Thanks.
