General

Requirements:
- Unity 2019.4 (or higher)
- Built-In Render Pipeline

Fading:
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.

Usage Tutorial

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.

UI Canvas

Overlay Filters can also be applied through UI Images.

Material Setup:
1. Expand the Space Settings section in the material.
2A. Set it to Screen for full-screen images.
2B. Or set it to UI Element for non-fullscreen images.
3. If you used UI Element you also need to fill in the Width and Height of the Image's RectTransform.

Troubleshooting

Particle Systems:
If you have a particle system using the overlay shader.
Do not use Fade With Alpha and use an Overlay Group.

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.

Performance

This asset only uses GPU Performance.
Which on most platforms does not affect FPS for 2D Games.

Performance Hints:
Using overlay-groups will significantly improve performance.
Only the first object within the same overlay-group will grab the screen-pixels.
Also make sure to disable overlays that are faded out.

Filters _{^{(look into the demo for combinations)}}

Unfiltered

The original for reference.

Reflect

Reflects the pixels above the sprite.
Combine it with other filters for a nice water effect.
*Only reflects pixels on screen (don’t move it too far up).
