Filter Shader

滤镜着色器

The Filter shader filters another shader or a bitmap. You can use it to adjust a shader or bitmap’s brightness, contrast, hue, saturation, gamma, gradient curves, etc.

滤镜着色器过滤另一个着色器或位图。您可以使用它来调整着色器或位图的亮度，对比度，色调，饱和度，伽马，渐变曲线等。

The Filter shader is especially useful for adjusting HDRI textures. For example, high-contrast HDRIs with bright lights usually cause flickering in the animation when rendering GI (Image Base Lighting). You can quickly resolve this problem by adjusting the Gamma value.

滤镜着色器对于调整 HDRI 纹理特别有用。例如，在渲染 GI (Image Base Lighting)时，带有明亮灯光的高对比度 hdri 通常会导致动画中出现闪烁。您可以通过调整 Gamma 值来快速解决此问题。
