Only enabled shaders and features use gpu performance.
The amount of active overlays matters a lot.
Disable gameobjects whenever you can to boost gpu performance.

The alpha channel will fade all shaders.
So any sprite renderer, image or particle system fading will also fade the filters.
Additional options can be found in the Fade Settings section.
1. Create a new Material
Rightclick in your Project Window and click on "Create" → "Material".
You may want to create a folder for your materials to keep things organized.

2. Assign the Overlay Shader to the Material
Select your new material and look at the Inspector Window.
The shader selection can be found at the top of the material inspector.
Select the "Overlay Filters" → "Overlay" shader.

3. Assign the Material to a 2D Object (SpriteRenderer, UI Image, Particle System, ...)
You can assign the material to almost every 2D Object.
Either look for the Material Slot in the object's inspector.
Or drag the material from the Project Window onto the object in the Scene Window.

4. Enable and Customize Filters
Filters can be enabled, customized and combined with each other.
Everything behind the overlay is affected by the enabled filters.
Multiple overlays can be stacked by layering them on top of each other.

If you have any questions or need assistance please contact me 🙂
Particle Systems:
If you have a particle system using the overlay shader.
Multiple particles of the same particle system won't overlap properly.
Only have a single active particle at a time per particle system component.

Sprite Renderers:
If you have multiple sprite renders using the overlay shader.
Their sorting order or z position should be different.
If they are rendered at the exact same order, they won't overlap properly.
