If you see on the video from 0.25 - 0.42 you see a shader used to mimic a glass cup. How does this shader works? I don’t think it simply “deforms” the enviroment around it. Any help on how to approach it would be really helpfull. Thanks!
Looks like its just using a cube map of the scene as an input.
I can’t help you write the shader to do it but that’s definitely a refraction shader
Unity Pro has a glass refraction package, but i’m not sure what you can do if you only have Unity free
