fog

Hi, I got  a scene with a fog.(type doesn't matter) Both rocks have the same distance to the camera. The left rock is a standard bumped specular the right one a shaderforge. The problem comes when you put 2 important directional lights in the scene. (I know not preferable but I hoped it was the solution until the shaderforge shader could receive vertex light) switching the multi light to single directional also fixes the problem.(duh, but I though  I mention it ;p)
