Clouds

This section contains settings for clouds.

Clouds Settings

Enabled	Toggles rendering of clouds on and off.
Fix Coverage Tiling	Toggles tiling reduction for the clouds coverage texture on and off. Such tiling becomes noticeable in large-scale worlds when observing clouds at significant distances. This option controls tiling reduction enabled per-material. Notice When enabled, additional texture fetching is performed, which affects performance, so use it wisely.
Sampling Quality	The number of noise samples used. This parameter affects cloud density. The following values are available: Low — 1 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	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	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	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	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	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 Notice When clouds are viewed from the ground or from above (at significant distance) and the viewer's velocity is less than 200 units per second, enabling this parameter can provide a significant gain in performance.
Downsampling Rendering	This parameter determines the clouds resolution based on a 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.
Detail Distortion	Texture type to be used for clouds distortion. The following types are available: 2D Texture — more performance-friendly, but may cause an excessive vertical extrusion of clouds. 3D Texture — ensures homogeneous detail distortion and better image quality, but at a higher performance cost.
Soft Intersection	Soft intersection distance for clouds, in meters.
Ground Shadows	Toggles rendering of clouds shadows on the ground on and off.
Shadow Shafts	Toggles rendering of shadow shafts for clouds on and off.
Render After Transparent	This parameter enables rendering of clouds after all transparent objects (except water).
Simplified Depth Test	Toggles simplified depth test for clouds on and off.
Noise Step	The amount of jitter in areas within clouds that is used to reduce banding effect due to an insufficient number of steps.
Noise Iterations	The amount of jitter used to reduce banding effect due to insufficient number of steps.
Noise Lighting	The amount of jitter for tracing steps of lighting calculation, which is used to reduce banding effect due to insufficient number of steps.
Noise Step Skip	The amount of jitter in areas between clouds, which is used to reduce banding effect due to insufficient number of steps.
Rounded	Toggles visual curving for clouds on and off. This option can be used to make clouds look more natural imitating planet's curvature.
Planet Radius	Planet radius to be used for clouds curving, in units.
