Struct CopyEffect

pub struct CopyEffect {
    pub write_mask: WriteMask,
    pub blend: Blend,
}

Copies the content of the color and/or depth texture by rendering a quad with those textures applied. The difference from ScreenEffect is that this effect does not apply any tone and color mapping specified in the Viewer.

Fields

write_mask: WriteMask

Defines which channels (red, green, blue, alpha and depth) to copy.

blend: Blend

Defines which type of blending to use when writing the copied color to the render target.
