Type members

• class var godotClassName: StringName

Instance members

• var audioListenerEnable2d: Bool

  If true, the viewport will process 2D audio streams.

• var audioListenerEnable3d: Bool

  If true, the viewport will process 3D audio streams.

• var canvasCullMask: UInt32

  The rendering layers in which this Viewport renders CanvasItem nodes.

• var canvasItemDefaultTextureFilter: Viewport.DefaultCanvasItemTextureFilter

  Sets the default filter mode used by CanvasItems in this Viewport. See DefaultCanvasItemTextureFilter for options.

• var canvasItemDefaultTextureRepeat: Viewport.DefaultCanvasItemTextureRepeat

  Sets the default repeat mode used by CanvasItems in this Viewport. See DefaultCanvasItemTextureRepeat for options.

• var canvasTransform: Transform2D

  The canvas transform of the viewport, useful for changing the on-screen positions of all child CanvasItems. This is relative to the global canvas transform of the viewport.

• var debugDraw: Viewport.DebugDraw

  The overlay mode for test rendered geometry in debug purposes.

• var disable3d: Bool

  Disable 3D rendering (but keep 2D rendering).

• var fsrSharpness: Double

  Determines how sharp the upscaled image will be when using the FSR upscaling mode. Sharpness halves with every whole number. Values go from 0.0 (sharpest) to 2.0. Values above 2.0 won’t make a visible difference.

• var globalCanvasTransform: Transform2D

  The global canvas transform of the viewport. The canvas transform is relative to this.

• var guiDisableInput: Bool

  If true, the viewport will not receive input events.

• var guiEmbedSubwindows: Bool

  If true, sub-windows (popups and dialogs) will be embedded inside application window as control-like nodes. If false, they will appear as separate windows handled by the operating system.

• var guiFocusChanged: Signal1

  Emitted when a Control node grabs keyboard focus.

• var guiSnapControlsToPixels: Bool

  If true, the GUI controls on the viewport will lay pixel perfectly.

• var handleInputLocally: Bool

  If true, this viewport will mark incoming input events as handled by itself. If false, this is instead done by the first parent viewport that is set to handle input locally.

• var meshLodThreshold: Double

  The automatic LOD bias to use for meshes rendered within the Viewport (this is analogous to meshLodThreshold). Higher values will use less detailed versions of meshes that have LOD variations generated. If set to 0.0, automatic LOD is disabled. Increase meshLodThreshold to improve performance at the cost of geometry detail.

• var msaa2d: Viewport.MSAA

  The multisample anti-aliasing mode for 2D/Canvas rendering. A higher number results in smoother edges at the cost of significantly worse performance. A value of 2 or 4 is best unless targeting very high-end systems. This has no effect on shader-induced aliasing or texture aliasing.

• var msaa3d: Viewport.MSAA

  The multisample anti-aliasing mode for 3D rendering. A higher number results in smoother edges at the cost of significantly worse performance. A value of 2 or 4 is best unless targeting very high-end systems. See also bilinear scaling 3d scaling3dMode for supersampling, which provides higher quality but is much more expensive. This has no effect on shader-induced aliasing or texture aliasing.

• var ownWorld3d: Bool

  If true, the viewport will use a unique copy of the World3D defined in world3d.

• var physicsObjectPicking: Bool

  If true, the objects rendered by viewport become subjects of mouse picking process.

• var physicsObjectPickingFirstOnly: Bool

  If true, the input_event signal will only be sent to one physics object in the mouse picking process. If you want to get the top object only, you must also enable physicsObjectPickingSort.

• var physicsObjectPickingSort: Bool

  If true, objects receive mouse picking events sorted primarily by their zIndex and secondarily by their position in the scene tree. If false, the order is undetermined.

• var positionalShadowAtlas16Bits: Bool

  Use 16 bits for the omni/spot shadow depth map. Enabling this results in shadows having less precision and may result in shadow acne, but can lead to performance improvements on some devices.

• var positionalShadowAtlasQuad0: Viewport.PositionalShadowAtlasQuadrantSubdiv

  The subdivision amount of the first quadrant on the shadow atlas.

• var positionalShadowAtlasQuad1: Viewport.PositionalShadowAtlasQuadrantSubdiv

  The subdivision amount of the second quadrant on the shadow atlas.

• var positionalShadowAtlasQuad2: Viewport.PositionalShadowAtlasQuadrantSubdiv

  The subdivision amount of the third quadrant on the shadow atlas.

• var positionalShadowAtlasQuad3: Viewport.PositionalShadowAtlasQuadrantSubdiv

  The subdivision amount of the fourth quadrant on the shadow atlas.

• var positionalShadowAtlasSize: Int32

  The shadow atlas’ resolution (used for omni and spot lights). The value is rounded up to the nearest power of 2.

• var scaling3dMode: Viewport.Scaling3DMode

  Sets scaling 3d mode. Bilinear scaling renders at different resolution to either undersample or supersample the viewport. FidelityFX Super Resolution 1.0, abbreviated to FSR, is an upscaling technology that produces high quality images at fast framerates by using a spatially aware upscaling algorithm. FSR is slightly more expensive than bilinear, but it produces significantly higher image quality. FSR should be used where possible.

• var scaling3dScale: Double

  Scales the 3D render buffer based on the viewport size uses an image filter specified in ProjectSettings/rendering/scaling3d/mode to scale the output image to the full viewport size. Values lower than 1.0 can be used to speed up 3D rendering at the cost of quality (undersampling). Values greater than 1.0 are only valid for bilinear mode and can be used to improve 3D rendering quality at a high performance cost (supersampling). See also ProjectSettings/rendering/antiAliasing/quality/msaa3d for multi-sample antialiasing, which is significantly cheaper but only smooths the edges of polygons.

• var screenSpaceAa: Viewport.ScreenSpaceAA

  Sets the screen-space antialiasing method used. Screen-space antialiasing works by selectively blurring edges in a post-process shader. It differs from MSAA which takes multiple coverage samples while rendering objects. Screen-space AA methods are typically faster than MSAA and will smooth out specular aliasing, but tend to make scenes appear blurry.

• var sdfOversize: Viewport.SDFOversize

  Controls how much of the original viewport’s size should be covered by the 2D signed distance field. This SDF can be sampled in CanvasItem shaders and is also used for GPUParticles2D collision. Higher values allow portions of occluders located outside the viewport to still be taken into account in the generated signed distance field, at the cost of performance. If you notice particles falling through LightOccluder2Ds as the occluders leave the viewport, increase this setting.

• var sdfScale: Viewport.SDFScale

  The resolution scale to use for the 2D signed distance field. Higher values lead to a more precise and more stable signed distance field as the camera moves, at the cost of performance.

• var sizeChanged: SimpleSignal

  Emitted when the size of the viewport is changed, whether by resizing of window, or some other means.

• var snap2dTransformsToPixel: Bool

  If true, CanvasItem nodes will internally snap to full pixels. Their position can still be sub-pixel, but the decimals will not have effect. This can lead to a crisper appearance at the cost of less smooth movement, especially when Camera2D smoothing is enabled.

• var snap2dVerticesToPixel: Bool

  If true, vertices of CanvasItem nodes will snap to full pixels. Only affects the final vertex positions, not the transforms. This can lead to a crisper appearance at the cost of less smooth movement, especially when Camera2D smoothing is enabled.

• var textureMipmapBias: Double

  Affects the final texture sharpness by reading from a lower or higher mipmap (also called “texture LOD bias”). Negative values make mipmapped textures sharper but grainier when viewed at a distance, while positive values make mipmapped textures blurrier (even when up close).

• var transparentBg: Bool

  If true, the viewport should render its background as transparent.

• var useDebanding: Bool

  If true, uses a fast post-processing filter to make banding significantly less visible in 3D. 2D rendering is not affected by debanding unless the backgroundMode is Environment/BGMode/bgCanvas. See also ProjectSettings/rendering/antiAliasing/quality/useDebanding.

• var useHdr2d: Bool

  If true, 2D rendering will use an high dynamic range (HDR) format framebuffer matching the bit depth of the 3D framebuffer. When using the Forward+ renderer this will be an RGBA16 framebuffer, while when using the Mobile renderer it will be an RGB10_A2 framebuffer. Additionally, 2D rendering will take place in linear color space and will be converted to sRGB space immediately before blitting to the screen (if the Viewport is attached to the screen). Practically speaking, this means that the end result of the Viewport will not be clamped into the 0-1 range and can be used in 3D rendering without color space adjustments. This allows 2D rendering to take advantage of effects requiring high dynamic range (e.g. 2D glow) as well as substantially improves the appearance of effects requiring highly detailed gradients.

• var useOcclusionCulling: Bool

  If true, OccluderInstance3D nodes will be usable for occlusion culling in 3D for this viewport. For the root viewport, ProjectSettings/rendering/occlusionCulling/useOcclusionCulling must be set to true instead.

• var useTaa: Bool

  Enables Temporal Anti-Aliasing for this viewport. TAA works by jittering the camera and accumulating the images of the last rendered frames, motion vector rendering is used to account for camera and object motion.

• var useXr: Bool

  If true, the viewport will use the primary XR interface to render XR output. When applicable this can result in a stereoscopic image and the resulting render being output to a headset.

• var vrsMode: Viewport.VRSMode

  The Variable Rate Shading (VRS) mode that is used for this viewport. Note, if hardware does not support VRS this property is ignored.

• var vrsTexture: Texture2D?

  Texture to use when vrsMode is set to Viewport/VRSMode/vrsTexture.

• var vrsUpdateMode: Viewport.VRSUpdateMode

  Sets the update mode for Variable Rate Shading (VRS) for the viewport. VRS requires the input texture to be converted to the format usable by the VRS method supported by the hardware. The update mode defines how often this happens. If the GPU does not support VRS, or VRS is not enabled, this property is ignored.
