This section contains settings of scene shadows.
|Enabled||Toggles rendering of shadows on and off.|
|Filter Mode||Global filtering mode to be used for shadows from all light sources by default. This mode determines quality of soft shadows. Higher quality produces smoother shadows. Available values:
You can set filtering mode or disable filtering for each light source individually.
|Filter Noise||Toggles the use of noise for shadow filtering on and off.
|Penumbra Mode||Global quality mode to be used for rendering penumbra from all light sources by default. This mode enables simulation of real-world shadows by keeping sharp contact shadows closer to the base and softening the farther the shadow stretches away. The higher the value the softer the shadows are. Available values:
You can set penumbra quality mode or disable penumbra rendering for each light source individually.
|Penumbra Noise||Toggles the use of noise for penumbra rendering on and off.
|Translucent Depth||A multiplier for the depth of light penetration into materials. Shows to what extent the translucent material is permeable to light.
|Lerp Shadow Cascades||Toggles linear interpolation of shadow cascades on and off. When enabled, transitions between cascades become smoother. However, the option drops performance as two shadow maps are rendered in transition areas.
When this option is disabled shadow cascades are not interpolated properly for Alpha Blend materials having the corresponding option enabled per-material.
|Screen Space Shadows||Toggles rendering of screen-space shadows on and off. When this option is enabled, penumbras from the light source are calculated using the ray tracing algorithm. The screen-space shadows should be used for small objects such as books, pens, etc. The option is available for all light sources and calculates shadows at any visibility distance.|
|Alpha Test Accounting||Toggles alpha test for shadows on and off.|
|Distance||Distance from the camera (in units), starting from which shadows from light sources are not rendered. Increasing the value produces blurred shadows.
In case this value is greater than the visibility distance for objects (Visibility Distances → Objects) the shadows will still be rendered even though the objects themselves are not. Please, pay attention to setting these parameters properly to avoid wasting performance on rendering unnecessary shadows.
|Distance Scale||Global shadow distance scale multiplier. This option allows a developer to easily increase or decrease shadows rendering performance by changing the scale.
In case this value is greater than the scale multiplier for objects (Visibility Distances → Distance Scale) the shadows will still be rendered even though the objects themselves are not. Please, make sure you set these parameters properly to avoid wasting performance on rendering unnecessary shadows.
