During my time at Liminal Game studios we worked at a game with the goal to give the player a dream like experience. To enhance the dream like feeling I set up and tested some different Post-Process materials. This is one of them where the edges of the player are getting some distortion. I set up some parameters for different alterations, like in/decreasing the radius of the effect, different distortion mask input, effect speed and color. This was one of subjects that really helped me better understand the material editor and different nodes inside of it to create in-game effects.
