-		[AnimatedTexture] is a resource format for frame-based animations, where multiple textures can be chained automatically with a predefined delay for each frame. Unlike [AnimationPlayer] or [AnimatedSprite], it isn't a [Node], but has the advantage of being usable anywhere a [Texture2D] resource can be used, e.g. in a [TileSet].

Unlike [AnimationPlayer] or [AnimatedSprite2D], it isn't a [Node], but has the advantage of being usable anywhere a [Texture2D] resource can be used, e.g. in a [TileSet].
 		The playback of the animation is controlled by the [member fps] property as well as each frame's optional delay (see [method set_frame_delay]). The animation loops, i.e. it will restart at frame 0 automatically after playing the last frame.
 		[AnimatedTexture] currently requires all frame textures to have the same size, otherwise the bigger ones will be cropped to match the smallest one. Also, it doesn't support [AtlasTexture]. Each frame needs to be separate image.

-		Camera is a special node that displays what is visible from its current location. Cameras register themselves in the nearest [Viewport] node (when ascending the tree). Only one camera can be active per viewport. If no viewport is available ascending the tree, the camera will register in the global viewport. In other words, a camera just provides 3D display capabilities to a [Viewport], and, without one, a scene registered in that [Viewport] (or higher viewports) can't be displayed.

 		An editor feature profile can be used to disable specific features of the Godot editor. When disabled, the features won't appear in the editor, which makes the editor less cluttered. This is useful in education settings to reduce confusion or when working in a team. For example, artists and level designers could use a feature profile that disables the script editor to avoid accidentally making changes to files they aren't supposed to edit.

 		Kinematic body 3D node.
 	</brief_description>
 	<description>
 		Kinematic bodies are special types of bodies that are meant to be user-controlled. They are not affected by physics at all; to other types of bodies, such as a character or a rigid body, these are the same as a static body. However, they have two main uses:
 		[b]Simulated motion:[/b] When these bodies are moved manually, either from code or from an [AnimationPlayer] (with [member AnimationPlayer.playback_process_mode] set to "physics"), the physics will automatically compute an estimate of their linear and angular velocity. This makes them very useful for moving platforms or other AnimationPlayer-controlled objects (like a door, a bridge that opens, etc).
-		[b]Kinematic characters:[/b] KinematicBody also has an API for moving objects (the [method move_and_collide] and [method move_and_slide] methods) while performing collision tests. This makes them really useful to implement characters that collide against a world, but that don't require advanced physics.

+		MultiMesh provides low-level mesh instancing. Drawing thousands of [MeshInstance3D] nodes can be slow, since each object is submitted to the GPU then drawn individually.
 		MultiMesh is much faster as it can draw thousands of instances with a single draw call, resulting in less API overhead.
 		As a drawback, if the instances are too far away of each other, performance may be reduced as every single instance will always rendered (they are spatially indexed as one, for the whole object).
 		Since instances may have any behavior, the AABB used for visibility must be provided by the user.

 		Some of this material's properties are applied to each particle when emitted, while others can have a [CurveTexture] applied to vary values over the lifetime of the particle.
 		When a randomness ratio is applied to a property it is used to scale that property by a random amount. The random ratio is used to interpolate between [code]1.0[/code] and a random number less than one, the result is multiplied by the property to obtain the randomized property. For example a random ratio of [code]0.4[/code] would scale the original property between [code]0.4-1.0[/code] of its original value.

 	</brief_description>
 	<description>
 		ProceduralSkyMaterial provides a way to create an effective background quickly by defining procedural parameters for the sun, the sky and the ground. The sky and ground are very similar, they are defined by a color at the horizon, another color, and finally an easing curve to interpolate between these two colors. Similarly, the sun is described by a position in the sky, a color, and an easing curve. However, the sun also defines a minimum and maximum angle, these two values define at what distance the easing curve begins and ends from the sun, and thus end up defining the size of the sun in the sky.
 		The [ProceduralSkyMaterial] uses a lightweight shader to draw the sky and is thus suited for real time updates. When you do not need a quick sky that is not realistic, this is a good option.
-		The [ProceduralSkyMaterial] supports up to 4 suns. Each sun takes its color, energy, and direction from the corresponding [DirectionalLight] in the scene.

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].

The instance must also be attached to the scenario using [method instance_set_scenario] in order to be visible.

 		Optionally, a viewport can have its own 2D or 3D world, so they don't share what they draw with other viewports.
 		If a viewport is a child of a [ViewportContainer], it will automatically take up its size, otherwise it must be set manually.
 		Viewports can also choose to be audio listeners, so they generate positional audio depending on a 2D or 3D camera child of it.

 		The [WorldEnvironment] node is used to configure the default [Environment] for the scene.
-		The parameters defined in the [WorldEnvironment] can be overridden by an [Environment] node set on the current [Camera]. Additionally, only one [WorldEnvironment] may be instanced in a given scene at a time.
+		The parameters defined in the [WorldEnvironment] can be overridden by an [Environment] node set on the current [Camera3D]. Additionally, only one [WorldEnvironment] may be instanced in a given scene at a time.
 		The [WorldEnvironment] allows the user to specify default lighting parameters (e.g. ambient lighting), various post-processing effects (e.g. SSAO, DOF, Tonemapping), and how to draw the background (e.g. solid color, skybox). Usually, these are added in order to improve the realism/color balance of the scene.

The node encapsulates the result of the CSG operations of its children. In this way, it is possible to do operations on one set of shapes that are children of one CSGCombiner node, and a set of separate operations on a second set of shapes that are children of a second CSGCombiner node, and then do an operation that takes the two end results as its input to create the final shape.
