Assign a material asset to a GameObject

To render a GameObject using a material:

1. Add a component that inherits from Renderer. MeshRenderer is the most common and is suitable for most use cases, but SkinnedMeshRenderer, LineRenderer, or TrailRenderer might be more suitable if your GameObject has special requirements.
2. Assign the material asset to the component’s Material property.

To render a particle system in the Built-in Particle System using a material:

1. Add a Renderer Module to the Particle System.
2. Assign the material asset to the Renderer Module’s Material property.
