Clouds Settings

Common#

Enable Clouds	value indicating if rendering of clouds is enabled. вкл. по умолчанию. Консольная команда: render_clouds_enabled (API)
Ground Shadows	value indicating if rendering of shadows from the clouds on the ground is enabled. вкл. по умолчанию. Консольная команда: render_clouds_ground_shadows (API)
Accurate Layers Sorting	value indicating if correct sorting of intersecting cloud layers is enabled. Примечание Enabling this feature may reduce raymarching quality as samples shall be distributed among all layers. выкл. по умолчанию. Консольная команда: render_clouds_accurate_layers_sorting (API)
Transparent Order	rendering order for clouds relative to transparent objects (except water). Render Before Transparent — render clouds before all transparent objects (except water). Render After Transparent — render clouds after all transparent objects (except water). Sort Transparent — enable rough sorting for transparent objects relative to clouds (below the lowest cloud layer base -> inside the clouds -> above the highest cloud layer top). Опция #1 установлена по умолчанию (см. выше). Консольная команда: render_clouds_transparent_order (API)
Detail Distortion	value indicating which texture type is used for clouds distortion at the moment. This parameter has a significant impact on performance: 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. Опция #1 установлена по умолчанию (см. выше). Консольная команда: render_clouds_distortion_texture (API)
Soft Intersection	soft intersection distance for clouds, in meters. Диапазон значений: [0.0f, 100000.0f]. Значение по умолчанию : 100.0f. Консольная команда: render_clouds_soft_intersection (API)

Quality#

Clouds quality rendering settings

Preset	index of the clouds quality preset used at the moment. Одно из следующих значений: Low (по умолчанию) Medium High + Interleaved High Ultra + Interleaved Ultra Extreme + Interleaved Extreme Custom Консольная команда: render_clouds_quality_preset (API)

Примечание

Presets override user-defined custom settings. When any preset other than Custom is active, modification of the parameters via API has no effect. The parameter value set via the last API call shall be used only when the Custom preset is active. When checking the current parameter value via API, you'll get the corresponding setting stored in the active preset (default or custom one).

Customizable Settings#

The following settings are available when the Custom preset is selected.

Clouds quality custom settings

Clouds Quality Settings

Sampling Quality	sampling quality for clouds. This parameter sets the number of noise samples that affects the cloud shape processing quality. The higher the value, the less are visual artifacts.
