Creating a glow effect with Shader Graph

In the previous recipe, a simple Shader Graph was created by using a Material for a primitive 3D Cube mesh. In this recipe, we'll take things further, creating a Shader Graph that applies a parameterized glow effect to a 3D object. The end result will look as follows:

Getting ready

This recipe builds on the previous one, so make a copy of that project and use the copy for this recipe.

How to do it...

To create a glow effect with a Shader Graph, follow these steps:

1. In the Project panel, create a new Physically-Based Rendering (PBR) Shader Graph, named glowShaderGraph. Choose menu: Create | Shader | PBR Graph.
2. In the Project panel, create a new Material named m_glow. Choose menu: Create | Material.
3. 3. With the m_glow selected, in the Inspector, set its Shader property to glowShaderGraph. For the Material'sShader property, choose menu: graphs | glowShaderGraph.

4. We now need a 3D mesh object in the scene that uses m_glow. While we could just use a 3D Cube again...
