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 Limits the amount of terrain's asynchronous operations per frame.
Mask Dithering Dither amount multiplier (in the [0.0f; 1.0f] range) used for rendering details of the Landscape Terrain. Dithering enables reduction of graphical artefacts in case of increased Mask Contrast values set per-detail. This is a global multiplier for dithering values set for each detail mask.

Geometry#

Terrain geometry rendering settings

Preset The terrain's geometry quality preset:
  • Low — low quality
  • Medium — medium quality
  • High — high quality
  • Ultra — ultra quality
  • Custom — adjust the quality manually
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).
Holes Toggles rendering of decal-based terrain holes on and off.
Visibility Distance Visibility distance of the Landscape Terrain in units.

Customizable Settings#

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

Geometry custom settings

Geometry Settings
Geometry Progression Progression of the Landscape Terrain geometry tessellation in the [0,50] range.

Geometry Fade Lods Intensity of fading between levels of geometry tessellation in the [0,1] range.

Geometry Subpixel Reduction Minimum ratio of a polygon size (in screen space) to the size of an area seen in the viewport in the [0,50] range. If the ratio calculated for the polygon is less than this value, such polygon will be removed.

Geometry Polygon Size Size of Landscape Terrain polygons in the [0.0001,1000.0] range, in units. The value defines the maximum allowed density of Landscape Terrain geometry.

Streaming#

Terrain streaming rendering settings

Preset The terrain's streaming quality preset:
  • Low — low quality
  • Medium — medium quality
  • High — high quality
  • Ultra — ultra quality
  • Custom — adjust the feature's quality manually
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).
Detail Albedo Texture Resolution Resolution of detail albedo textures of the Landscape Terrain. The following values are available:
  • 64×64
  • 128×128
  • 256×256
  • 512×512
  • 1024×1024
  • 2048×2048
  • 4096×4096
  • 8192×8192
  • 16384×16384
Detail Height Texture Resolution Resolution of detail height textures of the Landscape Terrain. The following values are available:
  • 64×64
  • 128×128
  • 256×256
  • 512×512
  • 1024×1024
  • 2048×2048
  • 4096×4096
  • 8192×8192
  • 16384×16384
Detail Additional Mask Texture Resolution Resolution of detail additional mask textures of the Landscape Terrain. The following values are available:
  • 64×64
  • 128×128
  • 256×256
  • 512×512
  • 1024×1024
  • 2048×2048
  • 4096×4096
  • 8192×8192
  • 16384×16384
Target Resolution Target resolution for the Landscape Terrain in pixels.
Texture Filtering Filtering mode between adjacent mip-levels of the render textures. The following values are available:
  • Low — use the lower mip-level
  • Medium — use the higher mip-level
  • High — linearly interpolate between adjacent mip-levels

Customizable Settings#

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

Streaming custom settings

Streaming Settings
Texture Memory Size Size of the Landscape Terrain render textures (albedo, normal and height). The value varies in the [0, 1] range:
  • 03072×3072 pixels (~200 MB of VRAM).
  • 116384×16384 pixels (~3.1GB of VRAM).
Detail Level By Angle Detail level reduction depending on the inclination of polygons relative to viewing direction. The value varies in the [0, 1] range:
  • 1 — pixel-to-pixel quality.
  • lower values decrease quality and can be used to reduce streaming load and memory consumption.

Tiles Update Per Frame Number of Landscape Terrain tiles checked to be updated per frame in the [1,256] range.
Tiles Load Per Frame Number of Landscape Terrain tiles loaded per frame when streamed in the [1,64] range.
Tiles Reload Per Frame Number of tiles reloaded per frame after the surface of the Landscape Terrain is modified in the [1,64] range.
Texel Size Texel size of the Landscape Terrain render textures in the [0.0001,1.0] range, in units. The value defines the maximum allowed level of detail for the albedo, normal and height textures of the Landscape Terrain.

Culling#

Culling Aggressive Toggles optimization of frustum culling on and off. When enabled, the number of culled polygons increases thereby increasing performance. If you have some issues with polygons rendering, try to disable the option (however, note that performance may drop).
Culling Frustum Padding Frustum padding 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.
Culling Back Face Threshold of backface culling. The value is the multiplier for the angle between the tessellation patch normal and the camera's view direction and used for culling the tessellation patches that are turned to the camera by their back faces. The higher the value, the less the angle between the patch normal and the camera's direction is required for culling this patch.
Culling Oblique Frustum Multiplier for culling of tessellation patches beyond the oblique frustum plane. The higher the value, the more patches will be culled.

Cache#

CPU Cache Size Limit of CPU cache in percentage of the total memory.
GPU Cache Size Limit of cache memory in percentage of the total GPU memory.
GPU Cache Life Time GPU cache lifetime in frames.
