The [VisualInstance3D] is used to connect a resource to a visual representation. All visual 3D nodes inherit from the [VisualInstance3D]. In general, you should not access the [VisualInstance3D] properties directly as they are accessed and managed by the nodes that inherit from [VisualInstance3D]. [VisualInstance3D] is the node representation of the [RenderingServer] instance.
Returns the RID of the resource associated with this [VisualInstance3D]. For example, if the Node is a [MeshInstance3D], this will return the RID of the associated [Mesh].
Returns the RID of this instance. This RID is the same as the RID returned by [method RenderingServer.instance_create]. This RID is needed if you want to call [RenderingServer] functions directly on this [VisualInstance3D].
Sets the resource that is instantiated by this [VisualInstance3D], which changes how the engine handles the [VisualInstance3D] under the hood. Equivalent to [method RenderingServer.instance_set_base].
For [Light3D]s, this can be used to control which [VisualInstance3D]s are affected by a specific light. For [GPUParticles3D], this can be used to control which particles are effected by a specific attractor. For [Decal]s, this can be used to control which [VisualInstance3D]s are affected by a specific decal.
