LogInKrystian Laskowski presented a neat setup and explained how it works.
Game Developer and 3D Artist Krystian Laskowski, also known as survivorr123, has recently garnered significant attention on Reddit, all thanks to the astounding custom-made setup that lets the author laser cut through meshes.
Powered by Unity, the framework was created using Shader Graph, the engine's tool that enables you to build shaders visually by creating and connecting nodes, instead of writing code, in combination with C#, the principal programming language of Unity, which governs the behavior and interaction of GameObjects. The creator stated that the system operates on object space coordinates and was developed solely as a proof of concept, not as a gameplay mechanic for any particular game project.
"[The system] uses one texture, red channel stores occlusion, blue channel stores time (for heat effect animation), green channel stores distance from the center of laser hit point, and alpha encodes normal with arctan2 for some basic shading," the creator explains. "It's then Ray Marched to create fake geometry. For rendering what's behind the object, it uses another camera with oblique projection."
