A project through which I'm exploring the structure of Unreal Engine 5, its rendering pipeline, and how to extend it.

I make use of the SceneViewExtension class, custom engine subsystem and a compute shader.

• FNoiseGenerationModule is responsible for mapping the custom shader source directory to the engine
• FNoiseGenSceneViewExtension inherits from FSceneViewExtensionBase, intializes and adds the renderpass and subscribes it to the PostProcessingPass. See GenerateNoise() in NoiseGenSceneViewExtension.cpp
• UNoiseGenerationSubsystem is responsible for initializing the FNoiseGenSceneViewExtension SVE
• Shader creation happens in NoiseGenerationShaders.h & .cpp

The noise generation is based on The Book of Shaders

It currently displays animated splatter noise from The Book of Shaders. I am planning to improve the noise generation, adding more variations (Perlin, White, Blue) and animating them.
