Inherits: Resource < Reference < Object

Resource for environment nodes (like WorldEnvironment) that define multiple rendering options.

Description

Resource for environment nodes (like WorldEnvironment) that define multiple environment operations (such as background Sky or Color, ambient light, fog, depth-of-field...). These parameters affect the final render of the scene. The order of these operations is:

  • Depth of Field Blur
  • Glow
  • Tonemap (Auto Exposure)
  • Adjustments

Enumerations

enum BGMode:

  • BG_CLEAR_COLOR = 0 --- Clears the background using the clear color defined in ProjectSettings.rendering/environment/default_clear_color.
  • BG_COLOR = 1 --- Clears the background using a custom clear color.
  • BG_SKY = 2 --- Displays a user-defined sky in the background.
  • BG_CANVAS = 3 --- Displays a CanvasLayer in the background.
  • BG_KEEP = 4 --- Keeps on screen every pixel drawn in the background. This is the fastest background mode, but it can only be safely used in fully-interior scenes (no visible sky or sky reflections). If enabled in a scene where the background is visible, "ghost trail" artifacts will be visible when moving the camera.
  • BG_CAMERA_FEED = 5 --- Displays a camera feed in the background.
  • BG_MAX = 6 --- Represents the size of the BGMode enum.

enum AmbientSource:

  • AMBIENT_SOURCE_BG = 0
  • AMBIENT_SOURCE_DISABLED = 1
  • AMBIENT_SOURCE_COLOR = 2
  • AMBIENT_SOURCE_SKY = 3

enum ReflectionSource:

  • REFLECTION_SOURCE_BG = 0
  • REFLECTION_SOURCE_DISABLED = 1
  • REFLECTION_SOURCE_SKY = 2

enum GlowBlendMode:

  • GLOW_BLEND_MODE_ADDITIVE = 0 --- Additive glow blending mode. Mostly used for particles, glows (bloom), lens flare, bright sources.
  • GLOW_BLEND_MODE_SCREEN = 1 --- Screen glow blending mode. Increases brightness, used frequently with bloom.
  • GLOW_BLEND_MODE_SOFTLIGHT = 2 --- Soft light glow blending mode. Modifies contrast, exposes shadows and highlights (vivid bloom).
  • GLOW_BLEND_MODE_REPLACE = 3 --- Replace glow blending mode. Replaces all pixels' color by the glow value. This can be used to simulate a full-screen blur effect by tweaking the glow parameters to match the original image's brightness.
  • GLOW_BLEND_MODE_MIX = 4

enum ToneMapper:

  • TONE_MAPPER_LINEAR = 0 --- Linear tonemapper operator. Reads the linear data and passes it on unmodified.
  • TONE_MAPPER_REINHARDT = 1 --- Reinhardt tonemapper operator. Performs a variation on rendered pixels' colors by this formula: color = color / (1 + color).
  • TONE_MAPPER_FILMIC = 2 --- Filmic tonemapper operator.
  • TONE_MAPPER_ACES = 3 --- Academy Color Encoding System tonemapper operator.

enum SSAOBlur:

  • SSAO_BLUR_DISABLED = 0 --- No blur for the screen-space ambient occlusion effect (fastest).
  • SSAO_BLUR_1x1 = 1 --- 1×1 blur for the screen-space ambient occlusion effect.
  • SSAO_BLUR_2x2 = 2 --- 2×2 blur for the screen-space ambient occlusion effect.
  • SSAO_BLUR_3x3 = 3 --- 3×3 blur for the screen-space ambient occlusion effect (slowest).

Setter set_ssr_fade_in(value)
Getter get_ssr_fade_in()

The fade-in distance for screen-space reflections. Affects the area from the reflected material to the screen-space reflection).

  • float ss_reflections_fade_out
Default 2.0
Setter set_ssr_fade_out(value)
Getter get_ssr_fade_out()

Default false
Setter set_ssao_enabled(value)
Getter is_ssao_enabled()

If true, the screen-space ambient occlusion effect is enabled. This darkens objects' corners and cavities to simulate ambient light not reaching the entire object as in real life. This works well for small, dynamic objects, but baked lighting or ambient occlusion textures will do a better job at displaying ambient occlusion on large static objects. This is a costly effect and should be disabled first when running into performance issues.

The default exposure used for tonemapping.

Default 0
Setter set_tonemapper(value)
Getter get_tonemapper()

Default 1.0
Setter set_tonemap_white(value)
Getter get_tonemap_white()

The white reference value for tonemapping. Only effective if the tonemap_mode isn't set to TONE_MAPPER_LINEAR.

Method Descriptions

  • bool is_glow_level_enabled ( int idx ) const

Returns true if the glow level idx is specified, false otherwise.

  • void set_glow_level ( int idx, bool enabled )

Enables or disables the glow level at index idx. Each level relies on the previous level. This means that enabling higher glow levels will slow down the glow effect rendering, even if previous levels aren't enabled.
