Noise And Grain
The Noise And Grain image effect simulates noise and film grain which is a typical effect happening in film or photography. This special noise implementation can even be used to enhance image contrast as it’s using a special blend mode. It also enables typical noise scenarios, such as as low level light noise or softening glowing halo’s or bloom borders.
The DirectX 11 / OpenGL 3 implementation is totally independent of any texture reads and thus a good fit for modern graphics hardware.
The standard version uses a noise texture that should have an average luminance of 0.5 to prevent unwanted brightness changes of the resulting image. The used default texture is an example for this.
Как и с другими эффектами изображения, этот эффект доступен только в Unity Pro и вы должны иметь установленные Pro Standard Assets перед тем как начать его использовать.
Свойства
| Свойство: | Функция: |
|---|---|
| DirectX11 Grain | Enable high quality noise and grain (DX11/GL3 only). |
| Monochrome | Use greyscale noise only. |
| Intensity Multiplier | Global intensity adjustment. |
| General | Add noise equally for all luminance ranges. |
| Black Boost | Add extra low luminance noise. |
| White Boost | Add extra high luminance noise. |
| Mid Grey | Defines ranges for high-level and low-level noise ranges above. |
| Color Weights | Additionally tint noise. |
| Texture | Texture used for non-DX11 mode. |
| Filter | Texture filtering. |
| Softness | Defines noise or grain crispness. Higher values might yield better performance but require temporary a render target. |
| Advanced | |
| Tiling | Noise pattern tiling (can be tweaked for all color channels individually when in non-DX11 texture mode). |
