Modify Post Processing Volume - Profile via script in Unity

Post Processing Volume

A post-processing volume is a feature in the Unity game engine that allows users to apply post-processing effects to a specific area of a scene. These effects can include bloom, depth of field, color grading, and other visual enhancements that can improve the overall aesthetic of a game or application. The post-processing volume is a volume object that can be placed in a scene, and its shape and size can be adjusted to control which objects in the scene are affected by the post-processing effects. The settings of the post-processing effects can be customized using a post-processing profile, which can be shared between multiple post-processing volumes in a scene. Post-processing volumes are a powerful tool for creating visually appealing scenes in Unity, and they can be used to add a professional polish to a game or application.

Example of script

To Modify the post-processing volume in Unity via a script, you will first need to create a new script and attach it to the post-processing volume object in your scene. Then, you can use the GetComponent<PostProcessVolume>() method to access the properties of the post-processing volume, and use the profile property to modify the settings of the post-processing effects. For example, you could use the following code to disable the depth of field effect in the post-processing volume:

PostProcessVolume volume = GetComponent<PostProcessVolume>();

volume.profile.depthOfField.enabled = false;

You can then use similar code to modify other post-processing settings as needed. Keep in mind that you will need to have the Post-processing package installed in Unity in order to use the post-processing volume and its associated scripts. You can learn more about post-processing in Unity on the Unity website.

Customize a value on Post Processing Profile:

To Modify a value on a post-processing profile in Unity, you can use the profile property of the PostProcessVolume component to access the settings of the post-processing effects. Then, you can use the appropriate property of the post-processing effect that you want to modify and set its value to the desired amount. For example, if you want to increase the intensity of the bloom effect, you could use the following code:

PostProcessVolume volume = GetComponent<PostProcessVolume>();

volume.profile.bloom.intensity = 2.0f;

This code will set the intensity of the bloom effect to 2.0. You can use similar code to modify other values on the post-processing profile as needed. Keep in mind that you will need to have the Post-processing package installed in Unity in order to use the post-processing volume and its associated scripts.
