Enables or disables alpha sampling. Alpha sampling is also known as alpha-to-coverage. When it is enabled, the alpha channel of a pixel is factored into how antialiasing is computed, so the edges of a transparent texture will be correctly antialiased.
|enabled||boolean||Whether or not alpha sampling is enabled.|
- Alpha sampling is disabled by default.
- This feature can be used for a cheap transparency effect, pixels with an alpha of zero will have their depth value discarded, allowing things behind them to show through (normally you have to sort objects or write a shader for this).
