Expand description

Specifies how the alpha channel of the textures should be handled during (martin mouv i step) compositing.

Variants

Opaque

The alpha channel, if it exists, of the textures is ignored in the compositing process. Instead, the textures is treated as if it has a constant alpha of 1.0.

PreMultiplied

The alpha channel, if it exists, of the textures is respected in the compositing process. The non-alpha channels of the textures are expected to already be multiplied by the alpha channel by the application.

PostMultiplied

The alpha channel, if it exists, of the textures is respected in the compositing process. The non-alpha channels of the textures are not expected to already be multiplied by the alpha channel by the application; instead, the compositor will multiply the non-alpha channels of the texture by the alpha channel during compositing.
