 		[CameraAttributesPhysical] is used to set rendering settings based on a physically-based camera's settings. It is responsible for exposure, auto-exposure, and depth of field.
 		When used in a [WorldEnvironment] it provides default settings for exposure, auto-exposure, and depth of field that will be used by all cameras without their own [CameraAttributes], including the editor camera. When used in a [Camera3D] it will override any [CameraAttributes] set in the [WorldEnvironment] and will override the [Camera3D]s [member Camera3D.far], [member Camera3D.near], [member Camera3D.fov], and [member Camera3D.keep_aspect] properties. When used in [VoxelGI] or [LightmapGI], only the exposure settings will be used.
 		The default settings are intended for use in an outdoor environment, tips for settings for use in an indoor environment can be found in each setting's documentation.

 		They are made of an [AABB] and a group of [Texture2D]s specifying [Color], normal, ORM (ambient occlusion, roughness, metallic), and emission. Decals are projected within their [AABB] so altering the orientation of the Decal affects the direction in which they are projected. By default, Decals are projected down (i.e. from positive Y to negative Y).
 		The [Texture2D]s associated with the Decal are automatically stored in a texture atlas which is used for drawing the decals so all decals can be drawn at once. Godot uses clustered decals, meaning they are stored in cluster data and drawn when the mesh is drawn, they are not drawn as a post-processing effect after.
 		[b]Note:[/b] Decals cannot affect an underlying material's transparency, regardless of its transparency mode (alpha blend, alpha scissor, alpha hash, opaque pre-pass). This means translucent or transparent areas of a material will remain translucent or transparent even if an opaque decal is applied on them.
+		[b]Note:[/b] Decals are only supported in the Forward+ and Mobile rendering methods, not Compatibility. When using the Mobile rendering method, only 8 decals can be displayed on each mesh resource. Attempting to display more than 8 decals on a single mesh resource will result in decals flickering in and out as the camera moves.
 		[b]Note:[/b] When using the Mobile rendering method, decals will only correctly affect meshes whose visibility AABB intersects with the decal's AABB. If using a shader to deform the mesh in a way that makes it go outside its AABB, [member GeometryInstance3D.extra_cull_margin] must be increased on the mesh. Otherwise, the decal may not be visible on the mesh.

 		An Omnidirectional light is a type of [Light3D] that emits light in all directions. The light is attenuated by distance and this attenuation can be configured by changing its energy, radius, and attenuation parameters.
+		[b]Note:[/b] When using the Mobile rendering method, only 8 omni lights can be displayed on each mesh resource. Attempting to display more than 8 omni lights on a single mesh resource will result in omni lights flickering in and out as the camera moves. When using the Compatibility rendering method, only 8 omni lights can be displayed on each mesh resource by default, but this can be increased by adjusting [member ProjectSettings.rendering/limits/opengl/max_lights_per_object].
 		[b]Note:[/b] When using the Mobile or Compatibility rendering methods, omni lights will only correctly affect meshes whose visibility AABB intersects with the light's AABB. If using a shader to deform the mesh in a way that makes it go outside its AABB, [member GeometryInstance3D.extra_cull_margin] must be increased on the mesh. Otherwise, the light may not be visible on the mesh.

 		[VoxelGI]s are used to provide high-quality real-time indirect light and reflections to scenes. They precompute the effect of objects that emit light and the effect of static geometry to simulate the behavior of complex light in real-time. [VoxelGI]s need to be baked before having a visible effect. However, once baked, dynamic objects will receive light from them. Furthermore, lights can be fully dynamic or baked.
+		[b]Note:[/b] [VoxelGI] is only supported in the Forward+ rendering method, not Mobile or Compatibility.
 		[b]Procedural generation:[/b] [VoxelGI] can be baked in an exported project, which makes it suitable for procedurally generated or user-built levels as long as all the geometry is generated in advance. For games where geometry is generated at any time during gameplay, SDFGI is more suitable (see [member Environment.sdfgi_enabled]).
 		[b]Performance:[/b] [VoxelGI] is relatively demanding on the GPU and is not suited to low-end hardware such as integrated graphics (consider [LightmapGI] instead). To improve performance, adjust [member ProjectSettings.rendering/global_illumination/voxel_gi/quality] and enable [member ProjectSettings.rendering/global_illumination/gi/use_half_resolution] in the Project Settings. To provide a fallback for low-end hardware, consider adding an option to disable [VoxelGI] in your project's options menus. A [VoxelGI] node can be disabled by hiding it.
 		[b]Note:[/b] Meshes should have sufficiently thick walls to avoid light leaks (avoid one-sided walls). For interior levels, enclose your level geometry in a sufficiently large box and bridge the loops to close the mesh. To further prevent light leaks, you can also strategically place temporary [MeshInstance3D] nodes with their [member GeometryInstance3D.gi_mode] set to [constant GeometryInstance3D.GI_MODE_STATIC]. These temporary nodes can then be hidden after baking the [VoxelGI] node.

 				Starts a new multiplayer client connecting to the given [param url]. TLS certificates will be verified against the hostname when connecting using the [code]wss://[/code] protocol. You can pass the optional [param tls_client_options] parameter to customize the trusted certification authorities, or disable the common name verification. See [method TLSOptions.client] and [method TLSOptions.client_unsafe].
