This shader was created by using the shader in this unity tutorial as a base: https://www.youtube.com/watch?v=gRq-IdShxpU From there I added features and adjust some fundamental behavior of the shader (like how much it deforms the original shilouette of the mesh, to suit the needs for the ghost project I was working on. I also converted my version of the shader so that it could be used for HDRP later on. This was created during a gamejam project through Seattle Indies. The outline effect is also a variation based on this tutorial: https://www.youtube.com/watch?v=74AS5DmLe8w&t=427s
In-Game effect.
