Enum Msaa 

pub enum Msaa {
    Off = 1,
    Sample2 = 2,
    Sample4 = 4,
    Sample8 = 8,
}

Component for configuring the number of samples for Multi-Sample Anti-Aliasing for a Camera.

Defaults to 4 samples. A higher number of samples results in smoother edges.

Some advanced rendering features may require that MSAA is disabled.

Note that the web currently only supports 1 or 4 samples.

Variants

Off = 1

Sample2 = 2

Sample4 = 4

Sample8 = 8
