Okay lets make sure I'm getting you in the shader folder there are two sharder folders one is glsl the other is the CG inside of both of these folders there are many folders like crt, 3dfx, retro... inside of these folders are individual shaders now these aren't the ones that you are are talking about needing the relative path are they they are the same ones I copy to the parent folder and they work fine for me when cycling through.
