Editing Shader (section)

=== GUI shader editors ===

Modern [[video game]] development platforms such as [[Unity (game engine)|Unity]], [[Unreal Engine]] and [[Godot (game engine)|Godot]] increasingly include [[node-based editor]]s that can create shaders without the need for actual code; the user is instead presented with a [[directed graph]] of connected nodes that allow users to direct various textures, maps, and mathematical functions into output values like the diffuse color, the specular color and intensity, roughness/metalness, height, normal, and so on. Automatic compilation then turns the graph into an actual, compiled shader.
