Landscape

The section contains settings that control rendering of Landscape Terrain.

Landscape rendering settings

Landscape Terrain rendering settings

All the settings are also available via Console.

Operations Per Frame The maximum number of Landscape texture draw operations (asyncTextureDraw) that can be performed per frame.
Range of values: [1, 1000]. The default value is 10.
Console access: render_landscape_operations_per_frame
Mask Dithering The global dither amount multiplier to be used for rendering details of the Landscape Terrain. Dithering enables reduction of graphical artefacts in case of increased Mask Contrast values set for a detail. This is a global multiplier for dithering values set for each detail mask.
Range of values: [0.0f, 1.0f]. The default value is 1.0f.
Console access: render_landscape_terrain_mask_dithering

Geometry#

Terrain geometry rendering settings

Preset The index of the currently used Landscape Terrain geometry preset.
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).
One of the following values:
  • Low (by default)
  • Medium
  • High
  • Ultra
  • Extreme
  • Custom

Console access: render_landscape_terrain_geometry_preset
Holes The value indicating if decal-based holes for the Landscape Terrain are enabled. Enabled by default.
Console access: render_landscape_terrain_geometry_holes
Visibility Distance The maximum visibility distance for the Landscape Terrain, in meters. The terrain is visible, as long as the distance between the camera and the terrain does not exceed this value.
Range of values: [0.0f, inf]. The default value is 30000.0f.
Console access: render_landscape_terrain_visible_distance

Customizable Settings#

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

Geometry Fade Lods The intensity of fading between levels of Global Water geometry tessellation. This value can be increased to remove sharp edges between areas with different geometry density.
Range of values: [0.0f, 1.0f]. The default value is 0.5f.
Console access: render_water_geometry_fade_lods

Geometry Subpixel Reduction The minimum ratio between the polygon size (in screen space) to the size of an area in the viewport for skipping polygons rendering (the ones having a lower ratio will be removed).

Notice
Presets override user-defined custom settings. When any preset other than Custom is active, modification of the parameters via API has no effect.

When checking the current parameter value via API you'll get the corresponding setting stored in the active preset (default or custom one).

Console access: render_landscape_terrain_vt_filtering

Customizable Settings#

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

Streaming custom settings

Streaming Settings
Texture Memory Size The value defining memory consumption for the Landscape Terrain textures. The value is interpreted as follows:
  • 0.0f - 3072×3072 (~200 MB of VRAM)
  • 1.0f - 16384×16384 (~3.1 GB of VRAM)

Range of values: [0.0f, 1.0f]. The default value is 0.4f.
Console access: render_landscape_terrain_vt_memory_size
Detail Level By Angle The value indicating detail level reduction depending on the inclination of the the Landscape Terrain polygons relative to viewing direction. Can be used to reduce streaming load and memory consumption. The value of 1 corresponds to the pixel-to-pixel quality, and lower values decrease it.
Range of values: [0.0f, 1.0f]. The default value is 0.95f.
Console access: render_landscape_terrain_vt_detail_level_by_angle

Tiles Update Per Frame The number of tiles passed to the virtual texture of the Landscape Terrain each frame.
Range of values: [1, 256]. The default value is 60.
Console access: render_landscape_terrain_vt_tiles_update_per_frame
Tiles Load Per Frame The number of Landscape Terrain tiles loaded per frame. You can decrease the value of this parameter to reduce spikes, but in this case streaming becomes slower and more noticeable.
Range of values: [1, 64]. The default value is 4.

Tiles Reload Per Frame The number of tiles to be reloaded per frame after applying changes to the Landscape Terrain surface.
Range of values: [1, 64]. The default value is 4.
Console access: render_landscape_terrain_vt_tiles_reload_per_frame
Texel Size The texel size of the Landscape Terrain render textures representing the maximum level of detail for the albedo, normal, and height components of the Landscape Terrain.

Console access: render_landscape_terrain_texel_size

Culling#

Culling Aggressive The value indicating if frustum culling optimization is enabled for the Landscape Terrain. When enabled, the number of culled polygons increases thereby increasing performance. In case of any issues with polygons rendering, try disabling this option (however, note that performance may drop). Enabled by default.
Console access: render_landscape_terrain_culling_aggressive
Culling Frustum Padding The multiplier for the size of viewing frustum to be used for culling polygons of the Landscape Terrain (value, by which the borders of the current frustum are increased). Frustum culling is performed for the frustum of the increased size. By the maximum value of 1, the frustum borders will be increased by the size of the current frustum.
Range of values: [0.0f, 1.0f]. The default value is 0.1f.
Console access: render_landscape_terrain_culling_frustum_padding
Culling Back Face The threshold used for culling tessellation patches of the Landscape Terrain oriented to the camera with their back faces (it is a multiplier for the angle between the tessellation patch normal and the camera's view direction). Higher values result in a smaller angle between the patch normal and the camera's view direction required for culling this patch.
Range of values: [0.0f, 1.0f]. The default value is 0.5f.
Console access: render_landscape_terrain_culling_back_face
Culling Oblique Frustum The multiplier for culling of tessellation patches of the Landscape Terrain beyond the oblique frustum plane. Higher values result in more patches culled.
Range of values: [0.0f, 1.0f]. The default value is 0.9f.
Console access: render_landscape_terrain_culling_oblique_frustum

Cache#

CPU Cache Size The CPU cache size to be used for landscape terrain rendering, in percentage of the total memory. CPU cache size affects intersections, physics, streaming, etc. The size of CPU cache depends on the scene.
Range of values: [1, 100]. The default value is 10.
Console access: render_landscape_cache_cpu_size
GPU Cache Size The GPU cache size to be used for landscape terrain rendering, in percentage of the total GPU memory. GPU cache is used to accumulate tiles, that are visible to the camera, before streaming them to the megatexture.
Notice
High-resolution maps require larger cache capacity.

Range of values: [1, 100]. The default value is 4.
Console access: render_landscape_cache_gpu_size
GPU Cache Life Time The lifetime of GPU cache used for Landscape Terrain rendering, in frames.
Range of values: [1, 60]. The default value is 4.
Console access: render_landscape_cache_gpu_life_time
