Beautiful… Releasing it? 
I wonder, any way to cast a lighter shadow? I wouldn’t think so short of another shader?
AFAIK shaders cannot control shadow intensity, only the actual light source like directional light can, I was going to ask the same question that if glass can even create shadows, and depending on the glass if its dirty or foggy it actually can.
releeeeeeeeeeeeeeeeaaaaaaaaaaaaaaaaaaase it please!!!
that shader looks awesome,
While the glass casting shadow, can it receive shadow to?
still working on it to receive shadow, AFAIK shadow intensity for casting is controlled by shadow intensity in directional light. or in shadow receive pass of the shader which attached to the receiver object.
how much is it going to cost?
I don’t know, currently this shader is simple enough for you to get it free actualy
that would be awesome!
