A glass shader that allows for better distortion and diffusion of light sources with post processing.
A comparision between this and the Unity Glass FX shader is provided in the screenshots below where this shader is featured on the left with the Unity shader on the right. The scene is setup so that each cube has an inner cube with a white emissive material applied to it, giving the effect a lamp with the glass cube. Bloom and glow are applied to the camera in order to emphasize the difference between this shader and the one included with Unity Pro.
Unity Pro is required for this shader to operate.
