There are two major things that you need to make objects glow in Unity. The first thing is the camera post processing bloom effect and the next is an emission material. In this tutorial, we will see how to achieve glow using them.
Adding post processing package
- Go to Window>Package Manager.
- Find Post processing and install it.
Getting things ready for Glow
- Right click on the project window and go to create>Post-Processing profile.
- Name it as Glow profile.
- Select any object in the hierarchy window. Then go to inspector and click layers>Add layer.
- Add a new layer called glow.
- Create a new material called Glow_material.
- Check the Emission and set the color to yellow (you can set it to the color of your choice)
Let’s get things glowing
