Film grain is the random optical texture of photographic film due to the presence of small particles of the metallic silver (or dye clouds for colored films) in the film stock.
電影顆粒是膠片上由於金屬銀(或彩色膠片上的染料雲)的小顆粒的存在而產生的隨機視覺感光紋理。
The Grain effect is based on a coherent gradient noise. It is commonly used to emulate the apparent imperfections of film and often exaggerated in horror themed games.
顆粒效果基於相干梯度噪聲。它通常被用來模仿電影的明顯瑕疵，並經常在恐怖主題的遊戲中被誇大。
Properties
| Property | Function |
|---|---|
| Colored | Enables the use of colored grain. |
| 彩色 | 允許使用彩色顆粒。 |
| Intensity | Grain strength. Higher means more visible grain. |
| 強度 | 顆粒強度。高意味着更多可見的顆粒。 |
| Size | Grain particle size. |
| 大小 | 粒子顆粒的大小 |
| Luminance Contribution | Controls the noisiness response curve based on scene luminance. Lower values mean less noise in dark areas. |
| 明亮度影響 | 基於場景亮度控制噪聲響應曲線。較低的數值意味着較低的噪音在黑暗地區。 |
Performances
Disabling Colored will make the effect run faster.
禁用着色將使效果運行得更快。
