<member name="rendering/anti_aliasing/quality/use_debanding" type="bool" setter="" getter="" default="false">
If [code]true[/code], uses a fast post-processing filter to make banding significantly less visible. If [member rendering/viewport/hdr_2d] is [code]false[/code], 2D rendering is [i]not[/i] affected by debanding unless the [member Environment.background_mode] is [constant Environment.BG_CANVAS]. If [member rendering/viewport/hdr_2d] is [code]true[/code], debanding will affect all 2D and 3D rendering, including canvas items.
If [code]true[/code], uses a fast dithering filter just before transforming floating point color values to integer color values to make banding significantly less visible. Debanding is applied at different steps of the rendering process depending on the rendering method and [member rendering/viewport/hdr_2d] setting.
In some cases, debanding may introduce a slightly noticeable dithering pattern. It's recommended to enable debanding only when actually needed since the dithering pattern will make lossless-compressed screenshots larger.
[b]Note:[/b] This property is only read when the project starts. To set debanding at runtime, set [member Viewport.use_debanding] on the root [Viewport] instead, or use [method RenderingServer.viewport_set_use_debanding].
[b]Note:[/b] This property is only read when the project starts and configures [method RenderingServer.material_set_use_debanding] and [member Viewport.use_debanding] of the root [Viewport]. When [member rendering/viewport/hdr_2d] is disabled, you should additionally set the [member Viewport.use_debanding] of other viewports in your project. To set debanding at run-time, the property that should be set depends on the renderer: Forward+ only uses [member Viewport.use_debanding] and Mobile uses both [method RenderingServer.material_set_use_debanding] and [member Viewport.use_debanding].

<member name="rendering/anti_aliasing/quality/use_taa" type="bool" setter="" getter="" default="false">
Enables temporal antialiasing for the default screen [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. Enabling TAA can make the image blurrier, which is partially counteracted by automatically using a negative mipmap LOD bias (see [member rendering/textures/default_filters/texture_mipmap_bias]).
