Pre-Defined Materials
Standard Material:
It is like the Default Material but can have assigned an effect.
Grayscale Material:
Applies a simple shader which displays the colors of the sprites as grayscale values.
Hue Saturation Brightness Material:
Allows to shift the colors of the sprites (hue), make them intense or gray (saturation) and darker or brighter (brightness). This is a very powerful shader which is shared between all Images using it. However, the values can be different on each instance. This is possible because of a trick and is much better for performance if you have a lot of images with this shader.
Not supported for Images with Filled mode.
Color Overlay Material:
The given color is not used to mix it with the sprite color but to overlay it. A value defines the opacity of the color (A value of 0 shows the original image, a value of 1 shows the color only).
Not supported for Images with Filled mode.
