Shadows

This section contains settings of scene shadows.

Shadows Settings

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:

Disabled - filtering for shadows is disabled, the stair-step effect is clearly seen at the edges of shadows.
Low — low quality
Medium — medium quality
High — high quality
Ultra — ultra quality

Notice

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:

Disabled - penumbra rendering is disabled, shadow edges are crisp and sharp (no shadow softness at all).
Low — low quality
Medium — medium quality
High — high quality
Ultra — ultra quality

Notice

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.

Translucent Depth = 0.06

Translucent Depth = 0.4

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.

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 Scale

Global shadow distance scale multiplier. This option allows a developer to easily increase or decrease shadows rendering performance by changing the scale.

Distance

Distance from the camera(in units), starting from which shadows from light sources are not rendered. Increasing the value produces blurred shadows.

Shadow Distance = 1200 units

Shadow Distance = 80 units
