How do I tweak the Standard Shader to achieve this thick translucent ice effect?

This was from CoD Infinite Warfare. I found the ice effect cool so I want to put it on my game.

This os what I have so far. As you can see, the Transparent effect does not achieve much.

 

You can't. You need a shader that can do translucent or subsurface lighting effects. The Standard Shader is incapable of either of those.

Try this:

follow this to make a surface shader that uses SSS custom lighting model:

you will need to bake a thickness map, such as in substance painter/designer

 

Thnanks guys. I will try those soon and post the results here
