Description

You will find inside Assets/Ressources/Materials the shader files needed for the tutorial

• SolidColor is a simple vertex and pixel shader which output a single color for each fragment
• GeometryShader is a simple geometry shader which will make the underlying geometry grows over time, also apply a smooth gradient based on 2 input properties inside the editor.
• SolidWithShadow same as SolidColor but add an extra include file at the end which will allow the mesh to cast a shadow on the scene, the codes came from a default ShaderGraph file, see in Shader graph's editor "View Generated Shader"
