Enum AlphaMode2d 

pub enum AlphaMode2d {
    Opaque,
    Mask(f32),
    Blend,
}

Sets how a 2d material’s base color alpha channel is used for transparency. Currently, this only works with Mesh2d. Sprites are always transparent.

This is very similar to AlphaMode but this only applies to 2d meshes. We use a separate type because 2d doesn’t support all the transparency modes that 3d does.

Variants

Opaque

Base color alpha values are overridden to be fully opaque (1.0).

Mask(f32)

Reduce transparency to fully opaque or fully transparent based on a threshold.

Compares the base color alpha value to the specified threshold. If the value is below the threshold, considers the color to be fully transparent (alpha is set to 0.0). If it is equal to or above the threshold, considers the color to be fully opaque (alpha is set to 1.0).

Blend

The base color alpha value defines the opacity of the color. Standard alpha-blending is used to blend the fragment’s color with the color behind it.
