Server for anything visible. Server for anything visible. The rendering server is the API backend for everything visible. The whole scene system mounts on it to display. The rendering server is completely opaque, the internals are entirely implementation specific and cannot be accessed. The rendering server can be used to bypass the scene system entirely. Resources are created using the [code]*_create[/code] functions. All objects are drawn to a viewport. You can use the [Viewport] attached to the [SceneTree] or you can create one yourself with [method viewport_create]. When using a custom scenario or canvas, the scenario or canvas needs to be attached to the viewport using [method viewport_set_scenario] or [method viewport_attach_canvas]. In 3D, all visual objects must be associated with a scenario. The scenario is a visual representation of the world. If accessing the rendering server from a running game, the scenario can be accessed from the scene tree from any [Node3D] node with [method Node3D.get_world_3d]. Otherwise, a scenario can be created with [method scenario_create]. Similarly in 2D, a canvas is needed to draw all canvas items. In 3D, all visible objects are comprised of a resource and an instance. A resource can be a mesh, a particle system, a light, or any other 3D object. In order to be visible resources must be attached to an instance using [method instance_set_base]. The instance must also be attached to the scenario using [method instance_set_scenario] in order to be visible. In 2D, all visible objects are some form of canvas item. In order to be visible, a canvas item needs to be the child of a canvas attached to a viewport, or it needs to be the child of another canvas item that is eventually attached to the canvas. https://docs.godotengine.org/en/latest/tutorials/optimization/using_servers.html Sets images to be rendered in the window margin.

Copies the viewport to a region of the screen specified by [code]rect[/code]. If [method viewport_set_render_direct_to_screen] is [code]true[/code], then the viewport does not use a framebuffer and the contents of the viewport are rendered directly to screen. However, note that the root viewport is drawn last, therefore it will draw over the screen. Accordingly, you must set the root viewport to an area that does not cover the area that you have attached this viewport to. For example, you can set the root viewport to not render at all with the following code: [codeblock] func _ready(): get_viewport().set_attach_to_screen_rect(Rect2()) $Viewport.set_attach_to_screen_rect(Rect2(0, 0, 600, 600)) [/codeblock] Using this can result in significant optimization, especially on lower-end devices. However, it comes at the cost of having to manage your viewports manually. For a further optimization see, [method viewport_set_render_direct_to_screen]. Creates an empty viewport and adds it to the RenderingServer. It can be accessed with the RID that is returned. This RID will be used in all [code]viewport_*[/code] RenderingServer functions.

If [code]true[/code], rendering of a viewport's environment is disabled. Sets the viewport's global transformation matrix. If [code]true[/code], the viewport's canvas is not rendered. Currently unimplemented in Godot 3.x. Sets the anti-aliasing mode. See [enum ViewportMSAA] for options. Sets the viewport's parent to another viewport. If [code]true[/code], render the contents of the viewport directly to screen. This allows a low-level optimization where you can skip drawing a viewport to the root viewport. While this optimization can result in a significant increase in speed (especially on older devices), it comes at a cost of usability. When this is enabled, you cannot read from the viewport or from the [code]SCREEN_TEXTURE[/code]. You also lose the benefit of certain window settings, such as the various stretch modes. Another consequence to be aware of is that in 2D the rendering happens in window coordinates, so if you have a viewport that is double the size of the window, and you set this, then only the portion that fits within the window will be drawn, no automatic scaling is possible, even if your game scene is significantly larger than the window size. Sets a viewport's scenario. The scenario contains information about the [enum ScenarioDebugMode], environment information, reflection atlas etc. Sets the shadow atlas quadrant's subdivision. Sets the size of the shadow atlas's images (used for omni and spot lights). The value will be rounded up to the nearest power of 2. Sets the viewport's width and height. If [code]true[/code], the viewport renders its background as transparent. Sets when the viewport should be updated. See [enum ViewportUpdateMode] constants for options. If [code]true[/code], the viewport uses augmented or virtual reality technologies. See [XRInterface]. If [code]false[/code], disables rendering completely, but the engine logic is still being processed. You can call [method force_draw] to draw a frame even with rendering disabled. Emitted at the end of the frame, after the RenderingServer has finished updating all the Viewports. Emitted at the beginning of the frame, before the RenderingServer updates all the Viewports.

Normal bias used to offset shadow lookup by object normal. Can be used to fix self-shadowing artifacts. Bias the shadow lookup to fix self-shadowing artifacts. Sets the size of the directional shadow pancake. The pancake offsets the start of the shadow's camera frustum to provide a higher effective depth resolution for the shadow. However, a high pancake size can cause artifacts in the shadows of large objects that are close to the edge of the frustum. Reducing the pancake size can help. Setting the size to [code]0[/code] turns off the pancaking effect. Blurs the edges of the shadow. Can be used to hide pixel artifacts in low resolution shadow maps. A high value can make shadows appear grainy and can cause other unwanted artifacts. Try to keep as near default as possible. Represents the size of the [enum LightParam] enum. Use a dual paraboloid shadow map for omni lights. Use a cubemap shadow map for omni lights. Slower but better quality than dual paraboloid. Use orthogonal shadow projection for directional light. Use 2 splits for shadow projection when using directional light. Use 4 splits for shadow projection when using directional light. Keeps shadows stable as camera moves but has lower effective resolution. Optimize use of shadow maps, increasing the effective resolution. But may result in shadows moving or flickering slightly.

Debug draw is disabled. Default setting. Objects are displayed without light information. Objects are displayed with only light information. Objects are displayed semi-transparent with additive blending so you can see where they are drawing over top of one another. A higher overdraw means you are wasting performance on drawing pixels that are being hidden behind others. Debug draw draws objects in wireframe. Normal buffer is drawn instead of regular scene so you can see the per-pixel normals that will be used by post-processing effects. Objects are displayed with only the albedo value from [GIProbe]s. Objects are displayed with only the lighting value from [GIProbe]s. Objects are displayed with only the emission color from [GIProbe]s. Draws the shadow atlas that stores shadows from [OmniLight3D]s and [SpotLight3D]s in the upper left quadrant of the [Viewport]. Draws the shadow atlas that stores shadows from [DirectionalLight3D]s in the upper left quadrant of the [Viewport]. Draws the screen space ambient occlusion texture instead of the scene so that you can clearly see how it is affecting objects. In order for this display mode to work, you must have [member Environment.ssao_enabled] set in your [WorldEnvironment]. Colors each PSSM split for the [DirectionalLight3D]s in the scene a different color so you can see where the splits are. In order they will be colored red, green, blue, yellow. Uses high quality importance sampling to process the radiance map. In general, this results in much higher quality than [constant Sky.PROCESS_MODE_REALTIME] but takes much longer to generate. This should not be used if you plan on changing the sky at runtime. If you are finding that the reflection is not blurry enough and is showing sparkles or fireflies, try increasing [member ProjectSettings.rendering/quality/reflections/ggx_samples]. Uses the fast filtering algorithm to process the radiance map. In general this results in lower quality, but substantially faster run times. [b]Note:[/b] The fast filtering algorithm is limited to 256x256 cubemaps, so [member Sky.radiance_size] must be set to [constant Sky.RADIANCE_SIZE_256]. Use the clear color as background. Use a specified color as the background. Use a sky resource for the background. Use a specified canvas layer as the background. This can be useful for instantiating a 2D scene in a 3D world.

Additive glow blending mode. Mostly used for particles, glows (bloom), lens flare, bright sources. Screen glow blending mode. Increases brightness, used frequently with bloom. Soft light glow blending mode. Modifies contrast, exposes shadows and highlights (vivid bloom). 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. Mixes the glow with the underlying color to avoid increasing brightness as much while still maintaining a glow effect. Output color as they came in. Use the Reinhard tonemapper. Use the filmic tonemapper. Use the ACES tonemapper. Disables the blur set for SSAO. Will make SSAO look noisier. Perform a 1x1 blur on the SSAO output. Performs a 2x2 blur on the SSAO output. Performs a 3x3 blur on the SSAO output. Use this for smoothest SSAO. Lowest quality of screen space ambient occlusion. Medium quality screen space ambient occlusion. High quality screen space ambient occlusion. Highest quality screen space ambient occlusion. Lowest quality DOF blur. This is the fastest setting, but you may be able to see filtering artifacts. Low quality DOF blur. Medium quality DOF blur. Highest quality DOF blur. Results in the smoothest looking blur by taking the most samples, but is also significantly slower. Calculate the DOF blur using a box filter. The fastest option, but results in obvious lines in blur pattern. Calculates DOF blur using a hexagon shaped filter. Calculates DOF blur using a circle shaped filter. Best quality and most realistic, but slowest. Use only for areas where a lot of performance can be dedicated to post-processing (e.g. cutscenes). Do not use a debug mode. Draw all objects as wireframe models. Draw all objects in a way that displays how much overdraw is occurring. Overdraw occurs when a section of pixels is drawn and shaded and then another object covers it up. To optimize a scene, you should reduce overdraw. Draw all objects without shading.

Represents the size of the [enum InstanceType] enum. A combination of the flags of geometry instances (mesh, multimesh, immediate and particles). Allows the instance to be used in baked lighting. Allows the instance to be used with dynamic global illumination. When set, manually requests to draw geometry on next frame. Represents the size of the [enum InstanceFlags] enum. Disable shadows from this instance. Cast shadows from this instance. Disable backface culling when rendering the shadow of the object. This is slightly slower but may result in more correct shadows. Only render the shadows from the object. The object itself will not be drawn. The nine patch gets stretched where needed. The nine patch gets filled with tiles where needed. The nine patch gets filled with tiles where needed and stretches them a bit if needed. Uses the default filter mode for this [Viewport]. The texture filter reads from the nearest pixel only. The simplest and fastest method of filtering, but the texture will look pixelized. The texture filter blends between the nearest 4 pixels. Use this when you want to avoid a pixelated style, but do not want mipmaps. The texture filter reads from the nearest pixel in the nearest mipmap. The fastest way to read from textures with mipmaps. The texture filter blends between the nearest 4 pixels and between the nearest 2 mipmaps. The texture filter reads from the nearest pixel, but selects a mipmap based on the angle between the surface and the camera view. This reduces artifacts on surfaces that are almost in line with the camera. The texture filter blends between the nearest 4 pixels and selects a mipmap based on the angle between the surface and the camera view. This reduces artifacts on surfaces that are almost in line with the camera. This is the slowest of the filtering options, but results in the highest quality texturing. Max value for [enum CanvasItemTextureFilter] enum. Uses the default repeat mode for this [Viewport]. Disables textures repeating. Instead, when reading UVs outside the 0-1 range, the value will be clamped to the edge of the texture, resulting in a stretched out look at the borders of the texture. Enables the texture to repeat when UV coordinates are outside the 0-1 range. If using one of the linear filtering modes, this can result in artifacts at the edges of a texture when the sampler filters across the edges of the texture. Flip the texture when repeating so that the edge lines up instead of abruptly changing. Max value for [enum CanvasItemTextureRepeat] enum. Adds light color additive to the canvas. Adds light color subtractive to the canvas. The light adds color depending on transparency. The light adds color depending on mask. Do not apply a filter to canvas light shadows.
