Flat Kit is a complete solution to achieve the stylish cel-shaded look: shaders, models, image effects, presets, examples. The custom shading model is versatile enough to work great for classic cel/toon shading and for unique styles of experimental projects.


  • Polished Cel shading with lots of capabilities (see below)
  • Gradient fog: Multi-stop horizontal/vertical gradient Fog Image Effect
  • Water shader
  • Outline Image Effect and Outline shader
  • LightPlane shader for 3D highlights and god rays
  • Mobile support
  • Built-in and URP support – all object shaders and post-processing effects support both rendering pipelines.
  • Terrain shader that works with Unity or third party terrain
  • Vertex color support (built-in RP only), also works with Polybrush
  • Ability to control Unity built-in shadows
  • Indirect lighting support
  • Intuitive, simple and streamlined interface — use only what you need
  • Color the scene precisely — without guesswork
  • Full source code
  • Elaborated online manual

Core Cel shader overview:
