Clouds

Common#

Enable Clouds	The value indicating if rendering of clouds is enabled. вкл. by default. Console access: render_clouds_enabled (API control)
Mode	The clouds rendering mode. Rendering clouds into the panorama cubemap texture once per frame automatically makes the clouds seen in simple default environment-based reflections making them look more natural for a reduced cost. However, rendering views from inside the clouds is possible in Volumetric mode only. One of the following values: Volumetric — render volumetric clouds (by default) Render To Panorama — render clouds to panorama (environment cubemap) Console access: render_clouds_mode (API control)
Panorama Resolution	The resolution of the panorama cubemap texture. Available for Render To Panorama clouds mode. One of the following values: 128x128 256x256 384x384 512x512 768x768 (by default) 1024x1024 1536x1536 2048x2048 4096x4096 Console access: render_clouds_panorama_resolution (API control)
Reuse Panorama Between Viewports	The value indicating if the panorama cubemap texture is reused between several viewports. Available for Render To Panorama clouds mode. выкл. by default. Console access: render_clouds_panorama_reuse (API control)
Ground Shadows	The value indicating if rendering of shadows from the clouds on the ground is enabled. вкл. by default. Console access: render_clouds_ground_shadows (API control)
Accurate Layers Sorting	The value indicating if correct sorting of intersecting cloud layers is enabled. Notice Enabling this feature may reduce raymarching quality as samples shall be distributed among all layers. выкл. by default. Console access: render_clouds_accurate_layers_sorting (API control)
Cutout By Far Clipping	The value indicating if far-plane clipping is used for clouds visibility. Controlling clouds visibility by increasing the far-plane distance significantly affects performance in many aspects (dynamic Environment Probes, etc.). You can disable this option when necessary as an optimization. вкл. by default. Console access: render_clouds_far_clipping (API control)
Transparent Order	The 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). Option #1 is selected by default (see above). Console access: render_clouds_transparent_order (API control)
Detail Distortion	The 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. Option #1 is selected by default (see above). Console access: render_clouds_distortion_texture (API control)
Soft Intersection	The soft intersection distance for clouds, in meters. Range of values: [0.0f, 100000.0f]. The default value is : 100.0f. Console access: render_clouds_soft_intersection (API control)

Clouds quality rendering settings

Preset	The index of the clouds quality preset used at the moment. One of the following values: Low (by default) Medium High + Interleaved High Ultra + Interleaved Ultra Extreme + Interleaved Extreme Custom Console access: render_clouds_quality_preset (API control)

Notice

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.
