The section contains settings that control rendering of Landscape Terrain.
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 (API control) |
|---|---|
| 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 (API control) |
Geometry#
| Preset |
The index of the Landscape Terrain geometry preset used at the moment. Notice One of the following values:
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).
Console access: render_landscape_terrain_geometry_preset (API control) |
|---|---|
| Holes |
The value indicating if decal-based holes for the Landscape Terrain are enabled. Enabled by default.
Console access: render_landscape_terrain_geometry_holes (API control) |
| 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 (API control) |
Customizable Settings#

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 (API control) |
Customizable Settings#
The following settings are available when the Custom preset is selected.
Streaming Settings
| Texture Memory Size |
The value defining memory consumption for the Landscape Terrain textures. The value is interpreted as follows:
Range of values: [0.0f, 1.0f]. The default value is 0.4f. Console access: render_landscape_terrain_vt_memory_size (API control) |
|---|---|
| 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 (API control)
|
| Tiles Update Per Frame |

|
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 (API control) |
|---|---|
| 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 (API control) |
| 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 (API control) |
| 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 (API control) |
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 (API control) |
|---|---|
| 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 (API control) |
| 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 (API control) |
