Pixelation image effect example.
- Add Pixelation Image Effect to the main camera.
- Add mask objects to specify the area of pixelation.
- Set Scale property to adjust the level of pixelation.
This effect uses alpha level on the framebuffer to blend the pixelated image (i.e. destination alpha blending). So you should place some objects which cover the area of pixelation. You can use AlphaFill shader to set the alpha level and leave the RGB levels.
