This panel allows adjusting the rendering settings of the world and can be invoked by pressing the R key (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.
|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).
|Light distance||Distance after which the dynamic lights are not be rendered.
|Object distance||Distance after which objects are not be rendered.|
|Shadow distance||Distance after which the shadows from light sources are not be rendered.
|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.
|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.|
|Field distance||Distance, at which (and farther) fields are not 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.|
|Ambient color||The color used to color all objects during the ambient rendering passes.|
|Reflection color||Color that allows to adjust reflections of all meshes with reflective materials, i.e.:
|Background color||Solid color rendered on the scene background. It For example, this option allows to create brighter, richer sky colors with light scattering.
|Environment||Environment cube map texture for image-based ambient lighting (light that is independent of direction). It realistically simulates light that comes from six main directions (per cube side). For example, objects are rendered bluish at the top (due to the sky color) and grayish or brownish at the bottom (due to the ground color).
Load, view or clear the environment cube-mapped texture.
Environment texture (can be smaller)Here is how the environment texture can increase the quality of the rendered scene.
|Exposure||The brightness of ambient lighting according to the environment texture.
|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

Effect is represented as Gaussian blur DOF and set via render_dof 1 console command.
To create the DOF effect in your application, you need to do three basic things:
- Set the point of focus with the Focal distance.
- 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).
- 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.
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.
|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.
|Far blur radius||Far blur radius is used for the out-of-focus objects that are outside Far blur range.
|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.
|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.
|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.|
|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.
|Near blur radius||Near blur radius is used for the out-of-focus objects that are outside Near blur range.
|Near blur power||Near blur power determines how fast the objects become blurred across the near blur range.
|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.
|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.
The tab contains properties of high-dynamic range rendering.
The filmic HDR provides better image quality. It lightens the darkest image regions and makes the lightest regions darker.
|Shoulder Scale||The Shoulder Strength filmic tone mapping parameter value that is used to change bright values.
|Linear Scale||The Linear Strength filmic tone mapping parameter value that is used to change grey values. The Linear Scale controls the length of the tone mapping curve linear part.

|Toe Scale||The Toe Strength filmic tone mapping parameter value that is used to change dark values. The Toe Scale controls the slope of the tone mapping curve toe (the area of underexposure).
|Toe Numerator||The Toe Numerator filmic tone mapping parameter value.|
|Toe Denominator||The Toe Denominator filmic tone mapping parameter value.|
|White Level||The Linear White Point filmic tone mapping parameter value, which is mapped as pure white in the resulted image.
All of this parameters represent the tone mapping curve, which is constructed by using the following formula:

- C - Linear Angle
- D - Toe Scale
- E - Toe Numerator
- F - Toe Denominator
