Not suitable for photo-realistic rendering but enough for casual use. Unity urp lit shader Unity urp lit shader. Shader Graph is one of my favorite Unity SRP features. Refraction can be observed very easily when looking at glass, water or any other transparent material that distorts the scene behind. Refraction is an effect that is not very easy nor intuitive to implement into realtime renderer. I would like to start by quickly reviewing the basic ray tracing theory. To apply warping in the screenspace to the texture we simply have to manipulate the screenUVs x and y component. The result is far from being a true refraction of course, but for the smartphone, and given the few resources that this requires, it works pretty good. full shader code is here. There is only a limited field of view rendered so using physically accurate vectors would result in lots of weird visuals where directional vectors would need to sample pixels that are not part of the rendered scene.
