Unity - Ice Shader

zach95564

Hello all! I'm working on a Unity game project with ShaderGraph and attempting to make a clear ice material that will be applied to a spherical object. The inspiration I have for this is a Mario odyssey Ice Kingdom esque material that that is mostly transparent with some displacement or bumps on the surface and maybe frozen air bubbles inside. (I have another detailed object that will be in the middle of the ice that has to be visible). 

Can't seem to find any tutorials on ShaderGraph, as most tutorials use ShaderForge or similar 3rd party plugin. 

I've so far been able to make a PBR glass material and was hoping to work from there, just curious if anybody has done something like this before and has some tips on a direction I can move towards? I'll attach the mario odyssey reference. 

I'm a bit disappointed I couldn't sort it out myself, i'm just at a bit of a loss with where to start as i'm newer to unity nodes. 

Thanks!

You might find something useful in this example package here:

There's a scene with floating crystals that look like they might be close to what you are looking for. And if my memory serves me right it uses a shadergraph shader.

If you have the glass working you are most of the way there. For the internal cracks use a parallax offset to make them feel embedded under the surface. I like to use a vertex blend or some sort of mask to go between frosted over and see through areas
