Implementation

• Creating alternative textures in Affinity Photo.
• Using Shader Graph to setup a Lit Shader Graph, to benefit from the Lighting Model to use Metallic, Smoothness and Emission.
• Create a reusable Sub Graph in Shader Graph, to transition the Main Texture and the Emission Texture.
• Custom Function node using an HLSL function to transition between two textures, given a threshold position and width.
• Use HDR to be able to define intensity for the threshold band.
• Post Processing Bloom effect to pick up the threshold band and generate a Glow effect.
• Manual Fresnel effect in a custom Unlit Shader using Cg.
• Fresnel achieved by doing the dot multiplication between the World Normal of the Fragment and the View Dir in World Space.
• C# Script to pass the position of the Scanner object to the Material holding the Shader, so it can move the threshold up and down.
