In this tutorial, I will be showing how to achieve a glowing effect using Unity's Post Processing package.
So let's begin!
First, we need to download the Post Processing package.
- In Unity go to Window -> Package Manager
- In Package Manager select "All packages"
- Wait for all packages to load, then select "Post Processing" from the list
- Click "Install" in the bottom right corner (if it's not installed yet) then wait for the package to install.
- Add the "Post Process Layer" component to the Main Camera
- Change its Layer variable to 'PostProcessing' (create a new layer with that name if you do not have any)
- Change Main Camera layer to 'PostProcessing'
- Add another component to the Main Camera called "Post Process Volume"
- Check the "Is Global" checkbox
- Right click on Assets folder -> Create -> Post-processing Profile, call it "BloomProfile"
- Select "BloomProfile" and in Inspector View click Add effect... -> Unity -> Bloom
- In Bloom effect check the Intensity, Diffusion, and Fast Mode checkboxes and set the values from the screenshot below:
- Assign "BloomProfile" to Profile variable in "Post Process Volume"
- Drag & Drop the object to which you want to apply the glowing effect into the Scene view (in my case it'll be a model of a Lightsaber)
- Select the material that you want to glow and make sure its Shader is set to "Standard"
- Enable the "Emission" checkbox
- Click on the "HDR" color and increase the "Intensity" value
The object should now glow:
