 	<description>
 		A PacketPeer implementation that should be passed to [member SceneTree.network_peer] after being initialized as either a client or server. Events can then be handled by connecting to [SceneTree] signals.
+		ENet's purpose is to provide a relatively thin, simple and robust network communication layer on top of UDP (User Datagram Protocol).
+		[b]Note:[/b] ENet only uses UDP, not TCP. When forwarding the server port to make your server accessible on the public Internet, you only need to forward the server port in UDP. You can use the [UPNP] class to try to forward the server port automatically when starting the server.

+# Open Source FBX Specification for the Importer
+
+The goal of this document is to make everything in FBX clearly stated, any errors will be corrected over time this
+is a first draft.
+
+## fbx parser - originally from assimp
+
+- Folder: /modules/fbx/fbx_parser
+- Upstream: assimp
+- Original Version: git (308db73d0b3c2d1870cd3e465eaa283692a4cf23, 2019)
+- License: BSD-3-Clause
+
+This can never be updated from upstream, we have heavily modified the parser to provide memory safety and add some
+functionality. If anything we should give this parser back to assimp at some point as it has a lot of new features.
+
+# Updating assimp fbx parser
+
+Don't. it's not possible the code is rewritten in many areas to remove thirdparty deps and various bugs are fixed.
+
+Many days were put into rewriting the parser to use safe code and safe memory accessors.
+
+# File Headers
+
+FBX Binaries start with the header "Kaydara FBX Binary"
+
+FBX ASCII documents contain a larger header, sometimes with copyright information for a file.
+
+Detecting these is pretty simple.
+
+# What is an OP link?
+It's an object to property link. It lists the properties for that object in some cases. Source and destination based by
+ID.
+
+# What is a OO link?
+Its an object to object link, it contains the ID source and destination ID.
+
+# FBX Node connections
+
+Nodes in FBX are connected using OO links, This means Object to Object.
+
+FBX has a single other kind of link which is Object Property, this is used for Object to Property Links, this can be
+ extra attributes, defaults, or even some simple settings.
+
+# Bones / Joints / Locators
+
+Bones in FBX are nodes, they initially have the Model:: Type, then have links to SubDeformer the sub deformer
+is part of the skin there is also an explicit Skin link, which then links to the geometry using OO links in the
+document.
+
+# Rotation Order in FBX compared to Godot
+
+**Godot uses the rotation order:** YXZ
+
+**FBX has dynamic rotation order to prevent gimbal lock with complex animations**
+
+```cpp
+enum RotOrder {
+	RotOrder_EulerXYZ = 0
+	RotOrder_EulerXZY,
+	RotOrder_EulerYZX,
+	RotOrder_EulerYXZ,
+	RotOrder_EulerZXY,
+	RotOrder_EulerZYX,
+	RotOrder_SphericXYZ // nobody uses this - as far as we can tell
+};
+```
+
+
+# Pivot transforms
+
+### Pivot description:
+- Maya and 3DS max consider everything to be in node space (bones joints, skins, lights, cameras, etc)
+- Everything is a node, this means essentially nodes are auto or variants
+- They are local to the node in the tree.
+- They are used to calculate where a node is in space
+```c++
+// For a better reference you can check editor_scene_importer_fbx.h
+// references: GenFBXTransform / read the data in
+// references: ComputePivotTransform / run the calculation
+// This is the local pivot transform for the node, not the global transforms
+Transform ComputePivotTransform(
+		Transform chain[TransformationComp_MAXIMUM],
+		Transform &geometric_transform) {
+	// Maya pivots
+	Transform T = chain[TransformationComp_Translation];
+	Transform Roff = chain[TransformationComp_RotationOffset];
+	Transform Rp = chain[TransformationComp_RotationPivot];
+	Transform Rpre = chain[TransformationComp_PreRotation];
+	Transform R = chain[TransformationComp_Rotation];
+	Transform Rpost = chain[TransformationComp_PostRotation];
+	Transform Soff = chain[TransformationComp_ScalingOffset];
+	Transform Sp = chain[TransformationComp_ScalingPivot];
+	Transform S = chain[TransformationComp_Scaling];
+
+	// 3DS Max Pivots
+	Transform OT = chain[TransformationComp_GeometricTranslation];
+	Transform OR = chain[TransformationComp_GeometricRotation];
+	Transform OS = chain[TransformationComp_GeometricScaling];
+
+	// Calculate 3DS max pivot transform - use geometric space (e.g doesn't effect children nodes only the current node)
+	geometric_transform = OT * OR * OS;
+	// Calculate standard maya pivots
+	return T * Roff * Rp * Rpre * R * Rpost.inverse() * Rp.inverse() * Soff * Sp * S * Sp.inverse();
+}
+```
+
+# Transform inheritance for FBX Nodes
+
+The goal of below is to explain why they implement this in the first place.
+
+The use case is to make nodes have an option to override their local scaling or to make scaling influenced by orientation, which i would imagine would be useful for when you need to rotate a node and the child to scale based on the orientation rather than setting on the rotation matrix planes.
+```cpp
+// not modified the formatting here since this code must remain clear
+enum TransformInheritance {
+	Transform_RrSs = 0,
+	// Parent Rotation * Local Rotation * Parent Scale * Local Scale  -- Parent Rotation Offset * Parent ScalingOffset (Local scaling is offset by rotation of parent node)
+	Transform_RSrs = 1, // Parent Rotation * Parent Scale * Local Rotation * Local Scale -- Parent * Local (normal mode)
+	Transform_Rrs = 2, // Parent Rotation * Local Rotation * Local Scale -- Node transform scale is the only relevant component
+	TransformInheritance_MAX // end-of-enum sentinel
+};
+
+enum TransformInheritance {
+	Transform_RrSs = 0,
+	// Local scaling is offset by rotation of parent node
+	Transform_RSrs = 1,
+	// Parent * Local (normal mode)
+	Transform_Rrs = 2,
+	// Node transform scale is the only relevant component
+	TransformInheritance_MAX // end-of-enum sentinel
+};
+```
+
+# Axis in FBX
+
+Godot has one format for the declared axis
+
+AXIS X, AXIS Y, -AXIS Z
+
+FBX supports any format you can think of. As it has to support Maya and 3DS Max.
+
+#### FBX File Header
+```json

+		P: "TimeMarker", "Compound", "", ""
+		P: "CurrentTimeMarker", "int", "Integer", "",-1
+	}
+}
+```
+
+#### FBX FILE declares axis dynamically using FBX header
+Coord is X
+Up is Y
+Front is Z
+
+#### GODOT - constant reference point
+Coord is X positive,
+Y is up positive,
+Front is -Z negative
+
+### Explaining MeshGeometry indexing
+
+Reference type declared:
+- Direct (directly related to the mapping information type)
+- IndexToDirect (Map with key value, meaning depends on the MappingInformationType)
+
+ControlPoint is a vertex
+* None The mapping is undetermined.
+* ByVertex There will be one mapping coordinate for each surface control point/vertex.
+    * If you have direct reference type vertices [x]
+    * If you have IndexToDirect reference type the UV
+* ByPolygonVertex There will be one mapping coordinate for each vertex, for every polygon of which it is a part. This means that a vertex will have as many mapping coordinates as polygons of which it is a part. (Sorted by polygon, referencing vertex)
+* ByPolygon There can be only one mapping coordinate for the whole polygon.
+    * One mapping per polygon polygon x has this normal x
+    * For each vertex of the polygon then set the normal to x
+* ByEdge There will be one mapping coordinate for each unique edge in the mesh. This is meant to be used with smoothing layer elements. (Mapping is referencing the edge id)
+* AllSame There can be only one mapping coordinate for the whole surface.

+	<description>
+		This is an FBX 3D asset importer with full support for most FBX features.
+		If exporting a FBX scene from Autodesk Maya, use these FBX export settings:
+		[codeblock]
+		- Smoothing Groups
+		- Smooth Mesh
+		- Triangluate (for meshes with blend shapes)
+		- Bake Animation
+		- Resample All
+		- Deformed Models
+		- Skins
+		- Blend Shapes
+		- Curve Filters
+		- Constant Key Reducer
+		- Auto Tangents Only
+		- *Do not check* Constraints (as it will break the file)
+		- Can check Embed Media (embeds textures into the exported FBX file)
+		  - Note that when importing embedded media, the texture and mesh will be a single immutable file.
+		  - You will have to re-export then re-import the FBX if the texture has changed.
+		- Units: Centimeters
+		- Up Axis: Y
+		- Binary format in FBX 2017

-			<description>
-				Stops the function execution and returns the current suspended state to the calling function.
-				From the caller, call [method GDScriptFunctionState.resume] on the state to resume execution. This invalidates the state. Within the resumed function, [code]yield()[/code] returns whatever was passed to the [code]resume()[/code] function call.
-				If passed an object and a signal, the execution is resumed when the object emits the given signal. In this case, [code]yield()[/code] returns the argument passed to [code]emit_signal()[/code] if the signal takes only one argument, or an array containing all the arguments passed to [code]emit_signal()[/code] if the signal takes multiple arguments.
-				You can also use [code]yield[/code] to wait for a function to finish:
-				[codeblock]
-				func _ready():
-				    yield(countdown(), "completed") # waiting for the countdown() function to complete
-				    print('Ready')
-
-				func countdown():
-				    yield(get_tree(), "idle_frame") # returns a GDScriptFunctionState object to _ready()
-				    print(3)
-				    yield(get_tree().create_timer(1.0), "timeout")
-				    print(2)
-				    yield(get_tree().create_timer(1.0), "timeout")
-				    print(1)
-				    yield(get_tree().create_timer(1.0), "timeout")
-
-				# prints:
-				# 3
-				# 2
-				# 1
-				# Ready
-				[/codeblock]
-				When yielding on a function, the [code]completed[/code] signal will be emitted automatically when the function returns. It can, therefore, be used as the [code]signal[/code] parameter of the [code]yield[/code] method to resume.
-				In order to yield on a function, the resulting function should also return a [code]GDScriptFunctionState[/code]. Notice [code]yield(get_tree(), "idle_frame")[/code] from the above example.

 		Uses an [OpenSimplexNoise] to fill the texture data. You can specify the texture size but keep in mind that larger textures will take longer to generate and seamless noise only works with square sized textures.
-		NoiseTexture can also generate normalmap textures.
+		NoiseTexture can also generate normal map textures.
 		The class uses [Thread]s to generate the texture data internally, so [method Texture2D.get_data] may return [code]null[/code] if the generation process has not completed yet. In that case, you need to wait for the texture to be generated before accessing the data:

The VP8 and VP9 codecs are more efficient than [VideoStreamTheora], but they require more CPU resources to decode (especially VP9). Both the VP8 and VP9 codecs are decoded on the CPU.
+		[b]Note:[/b] Alpha channel (also known as transparency) is not supported. The video will always appear to have a black background, even if it originally contains an alpha channel.

+		AR/VR interface using WebXR.
+	</brief_description>
+	<description>
+		WebXR is an open standard that allows creating VR and AR applications that run in the web browser.
+		As such, this interface is only available when running in an HTML5 export.
+		WebXR supports a wide range of devices, from the very capable (like Valve Index, HTC Vive, Oculus Rift and Quest) down to the much less capable (like Google Cardboard, Oculus Go, GearVR, or plain smartphones).
+		Since WebXR is based on Javascript, it makes extensive use of callbacks, which means that [WebXRInterface] is forced to use signals, where other AR/VR interfaces would instead use functions that return a result immediately. This makes [WebXRInterface] quite a bit more complicated to intialize than other AR/VR interfaces.
+		Here's the minimum code required to start an immersive VR session:
+		[codeblock]
+        var webxr_interface
+        var vr_supported = false
+
+        func _ready():
+            # We assume this node has a canvas layer with a button on it as a child.
+            # This button is for the user to consent to entering immersive VR mode.
+            $CanvasLayer/Button.connect("pressed", self, "_on_Button_pressed")
+
+            webxr_interface = XRServer.find_interface("WebXR")
+            if webxr_interface:
+                # WebXR uses a lot of asynchronous callbacks, so we connect to various
+                # signals in order to receive them.
+                webxr_interface.connect("session_supported", self, "_webxr_session_supported")
+                webxr_interface.connect("session_started", self, "_webxr_session_started")
+                webxr_interface.connect("session_ended", self, "_webxr_session_ended")
+                webxr_interface.connect("session_failed", self, "_webxr_session_failed")
+
+                # This returns immediately - our _webxr_session_supported() method
+                # (which we connected to the "session_supported" signal above) will
+                # be called sometime later to let us know if it's supported or not.
+                webxr_interface.is_session_supported("immersive-vr")

+            # simple 3DoF viewer ('viewer').
+            webxr_interface.session_mode = 'immersive-vr'
+            # 'bounded-floor' is room scale, 'local-floor' is a standing or sitting
+            # experience (it puts you 1.6m above the ground if you have 3DoF headset),
+            # whereas as 'local' puts you down at the XROrigin.
+            # This list means it'll first try to request 'bounded-floor', then
+            # fallback on 'local-floor' and ultimately 'local', if nothing else is
+            # supported.
+            webxr_interface.requested_reference_space_types = 'bounded-floor, local-floor, local'
+            # In order to use 'local-floor' or 'bounded-floor' we must also
+            # mark the features as required or optional.

+            webxr_interface.optional_features = 'bounded-floor'
+
+            # This will return false if we're unable to even request the session,
+            # however, it can still fail asynchronously later in the process, so we
+            # only know if it's really succeeded or failed when our
+            # _webxr_session_started() or _webxr_session_failed() methods are called.

+		[/codeblock]
+		There are several ways to handle "controller" input:
+		- Using [XRController3D] nodes and their [signal XRController3D.button_pressed] and [signal XRController3D.button_released] signals. This is how controllers are typically handled in AR/VR apps in Godot, however, this will only work with advanced VR controllers like the Oculus Touch or Index controllers, for example. The buttons codes are defined by [url=https://immersive-web.github.io/webxr-gamepads-module/#xr-standard-gamepad-mapping]Section 3.3 of the WebXR Gamepads Module[/url].
+		- Using [method Node._unhandled_input] and [InputEventJoypadButton] or [InputEventJoypadMotion]. This works the same as normal joypads, except the [member InputEvent.device] starts at 100, so the left controller is 100 and the right controller is 101, and the button codes are also defined by [url=https://immersive-web.github.io/webxr-gamepads-module/#xr-standard-gamepad-mapping]Section 3.3 of the WebXR Gamepads Module[/url].
+		- Using the [signal select], [signal squeeze] and related signals. This method will work for both advanced VR controllers, and non-traditional "controllers" like a tap on the screen, a spoken voice command or a button press on the device itself. The [code]controller_id[/code] passed to these signals is the same id as used in [member XRController3D.controller_id].
+		You can use one or all of these methods to allow your game or app to support a wider or narrower set of devices and input methods, or to allow more advanced interations with more advanced devices.

+				Gets an [XRPositionalTracker] for the given [code]controller_id[/code].
+				In the context of WebXR, a "controller" can be an advanced VR controller like the Oculus Touch or Index controllers, or even a tap on the screen, a spoken voice command or a button press on the device itself. When a non-traditional controller is used, interpret the position and orientation of the [XRPositionalTracker] as a ray pointing at the object the user wishes to interact with.
+				Use this method to get information about the controller that triggered one of these signals:

+				- [signal squeezestart]
