Rendering Settings

This panel allows adjusting the rendering settings of the world and can be invoked by pressing Alt+R (see Controls and Navigation). The panel has a set of tabs given below.

This tab contains the basic settings.

Distance scale	Global distance scale for all distance parameters, such as the world rendering distance, shadow distance, LOD distances etc. This option allows a developer to easily increase or decrease rendering performance by changing the world extent. Distance scale = 1 Distance scale = 0.3
World distance	Distance after which all nodes are not rendered or simulated (infinite by default). The distance is measured from the camera to the node. If the camera is within node bounds, the node is rendered no matter the World distance set (as in case with a ground on the picture below). World distance = inf World distance = 10 units
Physics distance	Distance after which physical interactions will not be calculated. All physics-based nodes freeze if the distance between them and the camera is bigger than the Physics distance. Physics distance = 40 units Physics distance = inf
Field distance	Distance, at which (and farther) fields are not rendered.
Decal distance	Distance after which decals will not be rendered.
Clutter distance	Distance after which clutter objects will not be rendered.
Reflection distance	Distance after which reflection will not be rendered.
World budget	World generation time budget for the Grass and Clutter objects in frames per second.
Physics budget	Physics simulation time budget in frames per second.
Render budget	Render creation time budget in frames per second. The render budget limits the number of loaded / created graphics resources during frame according to the loading / creation time.
Light distance	Distance after which the dynamic lights are not be rendered. Light distance = inf Light distance = 20 units
Object distance	Distance after which objects are not be rendered.
Shadow distance	Distance after which the shadows from light sources are not be rendered. Shadow distance = 1200 units Shadow distance = 80 units
Reflection color	Set reflection color for all meshes with reflective materials.
Wireframe color	Set color for meshes wireframe.
Background color	Solid color rendered on the scene background. It For example, this option allows to create brighter, richer sky colors with light scattering. Default background color Blue background
Render	Render postprocess materials applied before all other Unigine postprocess (such as HDR, DOF, etc.) are rendered. Several materials are separated by a comma (without whitespace). Custom postprocesses can also be set. For example, post_filter_scattering is set here. This way, subsurface scattering will be rendered first, and then correctly blurred with DOF.
Composite	This field allows to set the name of a custom composite shader. It will be used for the final composition of the full-screen image instead of the default one.
Post	Post postprocess materials applied at the end, after all other postprocess (such as HDR, DOF, etc.) are rendered. Such postprocesses, when applied to the screen image, affect HDR flares, glowing areas and so on. Several materials are separated by a comma (without whitespace). Custom postprocesses can also be set. Here is an example with post_blur_radial material. Radial blur post material

The tab contains different parameters that control some node or material settings across the whole world. That includes vegetation animation.

The tab contains settings related to screen-space ambient occlusion.

The tab contains settings related to the subsurface scattering.

Quality	Quality of the subsurface scattering: Low — low quality. Medium — medium quality. High — high quality. Ultra — ultra quality. Quality = Low Quality = Ultra
Resolution	Resolution used for the subsurface scattering: Half — half resolution. Full — full resolution.
Radius	The subsurface scattering multiplier: the bigger the value, the deeper the light goes through the mesh. Radius = 1 Radius = 0.2
Color	The subsurface scattering color.

The tab contains settings related to the water screen-space reflections.

The tab contains settings for rendering post-processes: motion blur, volumetric shadows and glow.

Refraction red	Refraction displacement for red channel (based on the refraction texture of refractive materials). It can be used to create light dispersion (chromatic aberrations). By the default value of 0, there is no dispersion for refracted light in red channel. No refraction dispersion Dispersion per channel: Red = 0.8, Green = 0.9, Blue = 1
Refraction green	Refraction displacement for green channel (based on the refraction texture of refractive materials). It can be used to create light dispersion (chromatic aberrations). By the default value of 0, there is no dispersion for refracted light in green channel.
Refraction blue	Refraction displacement for blue channel (based on the refraction texture of refractive materials). It can be used to create light dispersion (chromatic aberrations). By the default value of 0, there is no dispersion for refracted light in blue channel.
Motion blur linear	Amount of the motion blur when the player moves linearly. The higher the value, the more blurred the screen image will be when the camera moves in any direction.
Motion blur angular	Amount of the motion blur when the player rotates. The higher the value, the more blurred the screen image will be when the camera turns in any direction.
Motion blur velocity	Amount of the motion blur for the moving physical objects (with physical bodies assigned). The higher the value, the more blurred the objects will appear when moving.
Maximum velocity	The maximum possible amount of the motion blur for moving physical objects. When their body velocity exceeds the set value, they still will not be blurred any further.
Volumetric exposure	The exposure used for rendering volumetric shadows: By the minimum value of 0, there are no volumetric shadows visible. By the maximum value of 1, there volumetric shadows are the most dark and distinct.
Volumetric length	The length of volumetric shadows: By the minimum value of 0, there are no volumetric shadows visible. By the maximum value of 1, the volumetric shadows spread along the furthest distance, but are light in color.
Volumetric attenuation	How fast volumetric shadows fade out along their length: By the value of 1 there is no additional attenuation. The lower the value, the smaller the shadow is.
Glow threshold	The brightness threshold, which is used to detect, if an object is bright enough to produce glow: By the minimum value of 0, all bright objects are rendered glowing. The higher the value, the more bright the object should be to produce glow.
Glow small	Brightness of the small-radius glow. This glow effect is rendered most close to the glowing surface and creates object-shaped highlight. Small-radius glow
Glow medium	Brightness of the medium-radius glow. This glow effect creates a medium-sized halo close to the glowing surface. Medium-radius glow
Glow large	Brightness of the large-radius glow. This glow effect creates a large-sized halo around the glowing surface. Large-radius glow

The tab contains settings used to create the depth of field effect.

Effect is represented as Gaussian blur DOF and set via render_dof1console command.

To create the DOF effect in your application, you need to do three basic things:

1. Set the point of focus with the Focal distance.
2. Set the length of in-focus area with non-zero Near blur range (before the point of focus) and Far blur range (after the point of focus).
3. Set the Far blur radius and Near blur radius.

Focal distance	The focal distance of the camera. It sets a line where objects are in focus and can be seen clearly. The higher the value, the further from the camera the in-focus area will be. Focal distance is only a reference point. The width of the in-focus area is defined by Near blur range and Far blur range parameters. Notice If the Focal distance is set to 0 (i.e. objects right in front of the camera are in focus), there is no near blurring distance. It means that all the other Near parameters are ignored. Focal distance = 10 units Focal distance = 30 units
Far  blur  range	Far blur range is measured from the Focal distance point and away from the camera. It sets the length of the area (in units) within which objects are focused out, i.e. become blurred in the background. The higher the value, the farther from the camera spreads the transition area between non-blurred area to the blurred one. As a result, you can see more objects in focus. By the minimum value of 0, there is no smooth transition. Everything that is farther than the Focal distance point, is abruptly blurred. Notice If the Near blur range is also equal to 0, there will be no in-focus area at all. Far blur range = 4 units Far blur range = 13 units
Far  blur  radius	Far blur radius is used for the out-of-focus objects that are outside Far blur range. The higher the value, the more blurred the out-of-focus areas are. Blur radius = 0.5 Blur radius = 2
Far  blur  power	Far blur power acts the same way as the Near blur power — it determines how fast the objects become blurred across the far blur range. By low value, objects become blurred right after the Focal distance point. By high the value, it takes long distance for objects to become blurred.
Far  focal  range	Far focal range determines the area between the focal point and objects in crisp focus (not blurred).
Far  focal  scale	Far focal csale is an interpolation coefficient between a non-blurred screen image and a blurred one. Shifts the Far blur range closer to the camera. The higher the value, the less is the Far blur range and the closer the blurring starts to the camera.
Far  focal  power	Far focal power also acts the same way as the Near focal power. It allows to adjust the DOF across the far blur range. But unlike the Far blur power, it tweaks both the rate of blurring and intensity of bokeh at the same time. By low value, objects become out-of-focus right after the Focal distance point. By high the value, they stay in-focus up to the very end of the far blur range.
Near  blur  range	Near blur range is measured from the Focal distance point towards the camera. It sets the length of the area (in units) within which objects are focused on, i.e. become clearly seen. The higher the value, the closer to the camera spreads the transition area between blurred area to non-blurred one. As a result, you can see more objects in focus. By the minimum value of 0, there is no smooth transition. Everything that is closer than the Focal distance point, is abruptly blurred. Notice If the Far blur range is also equal to 0, there will be no in-focus area at all. If the Focal distance is set to 0, Near blur range parameter is ignored. Near blur range = 4 units Near blur range = 13 units
Near  blur  radius	Near blur radius is used for the out-of-focus objects that are outside Near blur range. The higher the value, the more blurred the out-of-focus areas are.
Near  blur  power	Near blur power determines how fast the objects become blurred across the near blur range. By low value, objects become blurred very close to the Focal distance point. By high the value, it takes long distance for objects to become blurred. Near blur power = 0.2 Near blur power = 1.5
Near  focal  range	Near focal range determines the area between the focal point and objects in crisp focus (not blurred).
Near  focal  scale	Near focal csale is an interpolation coefficient between a non-blurred screen image and a blurred one. Shifts the Near blur range closer to the camera. The higher the value, the less is the Near blur range and the closer the blurring starts to the camera.
Near  focal  power	Near focal power also allows to adjust the DOF across the near blur range. But unlike the Near blur power, it tweaks both the rate of blurring and intensity of bokeh at the same time. By low value, objects become out-of-focus very close to the Focal distance point (right before it). By high the value, they stay in-focus up to the very end of the near blur range. Near focal power = 0.2 Near focal power = 1.5
