SwiftUI in visionOS has a modifier called preferredSurroundingsEffect that takes a SurroundingsEffect.
From what I can tell, there is only a single effect available: .systemDark.
ImmersiveSpace(id: "MyView") {
MyView()
.preferredSurroundingsEffect(.systemDark)
}
I'd like to create another effect to tint the color of passthrough video if possible.
Does anyone know how to create custom SurroundingsEffects?

In a RealityView, I have scene loaded from Reality Composer Pro. The entity I'm interacting with has a PhysicallyBasedMaterial with a diffuse color. I want to change that color when on long press. I can get the entity and even get a reference to the material, but I can't seem to change anything about it.
What is the best way to change the color of a material at runtime?
var longPress: some Gesture {
LongPressGesture(minimumDuration: 0.5)
.targetedToAnyEntity()
.onEnded { value in
value.entity.position.y = value.entity.position.y + 0.01
if var shadow = value.entity.components[GroundingShadowComponent.self] {
shadow.castsShadow = true
value.entity.components.set(shadow)
}
if let model = value.entity.components[ModelComponent.self] {
print("material", model)
if let mat = model.materials.first {
print("material", mat)
// I have a material here but I can't set any properties?
// mat.diffuseColor does not exist
}
}
}
}
Here is the full code
struct Lab5026: View {
var body: some View {
RealityView { content in
if let root = try? await Entity(named: "GestureLab", in: realityKitContentBundle) {
root.position = [0, -0.45, 0]
if let subject = root.findEntity(named: "Cube") {
subject.components.set(HoverEffectComponent())
subject.components.set(GroundingShadowComponent(castsShadow: false))
}
content.add(root)
}
}
.gesture(longPress.sequenced(before: dragGesture))
}
var longPress: some Gesture {
LongPressGesture(minimumDuration: 0.5)
.targetedToAnyEntity()
.onEnded { value in
value.entity.position.y = value.entity.position.y + 0.01
if var shadow = value.entity.components[GroundingShadowComponent.self] {
shadow.castsShadow = true
value.entity.components.set(shadow)
}
if let model = value.entity.components[ModelComponent.self] {
print("material", model)
if let mat = model.materials.first {
print("material", mat)
// I have a material here but I can't set any properties?
// mat.diffuseColor does not exist
// PhysicallyBasedMaterial
}
}
}
}
var dragGesture: some Gesture {
DragGesture()
.targetedToAnyEntity()
.onChanged { value in
let newPostion = value.convert(value.location3D, from: .global, to: value.entity.parent!)
let limit: Float = 0.175
value.entity.position.x = min(max(newPostion.x, -limit), limit)
value.entity.position.z = min(max(newPostion.z, -limit), limit)
}
.onEnded { value in
value.entity.position.y = value.entity.position.y - 0.01
if var shadow = value.entity.components[GroundingShadowComponent.self] {
shadow.castsShadow = false
value.entity.components.set(shadow)
}
}
}
}

How can we move the player within a RealityKit/RealityView scene? I am not looking for any animation or gradual movement, just instantaneous position changes.
I am unsure of how to access the player (the person wearing the headset) and it's transform within the context of a RealityView.
The goal is to allow the player to enter a full space in immersive mode and explore a space with various objects. They should be able to select an object and move closer to it.
