Clouds

This section contains settings for clouds.

Clouds Settings

Sampling Quality	This parameter determines the number of samples used and affects cloud density. The following values are available: Low - 1 noise sample, low quality (higher density). Medium - 3 samples, medium quality (by default). High - 5 samples, high quality. Ultra - 6 samples, ultra quality (lower density, the clouds are softer). Notice Visual difference between low and ultra quality is not significant. Therefore, it is recommended to use low settings, when possible, to gain performance.
Lighting Quality	This parameter determines the number of samples used to calculate lighting for clouds. The following values are available: Low - 1 sample, low quality. Medium - 3 samples, medium quality (by default). High - 5 samples, high quality. Ultra - 6 samples, ultra quality. Notice This parameter has a significant impact on performance. Therefore, it is recommended to use low settings, when possible.
Samples Count	This parameter determines the number of samples used for clouds rendering. The following values are available: Low - 1 sample, low quality. Medium - 3 samples, medium quality (by default). High - 5 samples, high quality. Ultra - 6 samples, ultra quality.
Lighting Trace Length	This parameter determines the maximum length of a sun ray traced inside a cloud, in units.
Lighting Cone Radius	Lighting cone sampling radius for clouds lighting. Notice Low values may result in unnatural behavior as the position of the sun changes.
Dynamic Coverage Area	This parameter determines visibility distance for coverage of FieldWeather objects, in units. Notice In UnigineEditor this area is marked with a bounding box. When the camera is outside this box, the FieldWeather coverage is not visible. Increasing dynamic coverage area leads to reduction of quality of FieldWeather coverage texture and loss of details. This effect can be mitigated by increasing dynamic coverage resolution.
Dynamic Coverage Resolution	This parameter determines the quality of dynamic coverage texture for FieldWeather objects. The following values are available: 128 x 128. 256 x 256 (by default). 512 x 512. 1024 x 1024. 2048 x 2048. Higher values make it possible to preserve texture details at high distances. Notice Increased resolution significantly affects performance.
Interleaved Rendering	Interleaved rendering mode for clouds. The following values are available: disabled (by default). 2 x 2. 4 x 4. 8 x 8. Notice In cases when clouds are viewed from the ground, or from above (at significant distance) and viewer's velocities are less than 200 units per second. This parameter can be used to provide a significant gain in performance.
Downsampling Rendering	This parameter determines clouds resolution based on current screen resolution. The following values are available: Full - full resolution. Half - half resolution (by default). Quarter - quarter resolution. Notice This parameter has a significant impact on performance.
Soft Intersection	This parameter determines soft intersection distance for clouds in meters.
Render After Transparent	This parameter enables rendering of clouds after all transparent objects (except water).
Noise Step	This parameter determines the amount of jitter in the areas within clouds, that is used to reduce banding effect due to insufficient number of steps.
Noise Iterations	This parameter determines the amount of jitter, that is used to reduce banding effect due to insufficient number of steps.
Noise Lighting	This parameter determines the amount of jitter for tracing steps of lighting calculation, that is used to reduce banding effect due to insufficient number of steps.
Noise Step Skip	This parameter determines the amount of jitter in the areas between clouds, that is used to reduce banding effect due to insufficient number of steps.
