This week we have a quick look at why small values of Refraction clip and how we can make a simple, non-destructive, edit to the shader file to fix this.

//clip if the distortion distance (squared) is too small to be noticed
//this will result in a less expensive apply pass since the clipped pixels won't set stencil to pass
if (TryToClip)
{
#if OVERRIDE_DISTORTION_CLIP
clip(dot(BufferUVDistortion, BufferUVDistortion) - .00000001);
#else
clip(dot(BufferUVDistortion, BufferUVDistortion) - .001);
#endif
}
