How can you create planes with a repeated image texture in RealityKit?

edit

To create planes with a repeated image texture in RealityKit, follow these steps:

1. Start by creating a new RealityKit project in Xcode.

2. Create a new entity and add a mesh component to it. The mesh component will define the shape of the geometry for the entity.

3. Create a new material for the entity by adding a material component to it. A material defines the properties of the surface of the entity.

4. Add the image you want to use as a texture to your project by dragging it into the Assets.xcassets folder. Make sure the image is selected and go to the Attributes Inspector on the right-hand side of Xcode.

5. Check the "Repeat" checkbox in the Texture section.

6. Go back to your entity's material and set the texture to the image you just added.

7. Set the tiling of the texture by modifying the "textureScaling" property of your material. This property takes a vector with the X and Y scaling factors for the texture.

For example, the following code sets the textureScaling property to a vector with X and Y values of 3:

let material = SimpleMaterial()
material.texture = TextureResource.generate(with: UIImage(named: "texture.png")!)
material.texture!.tiing = .init(Float(3), Float(3))
entity.model?.materials = [material]

By setting the textureScaling property, you can control how many times the texture is repeated across the surface of the entity.

1. Finally, add your entity to the scene and run the app to see the repeated image texture on your plane.

let anchor = AnchorEntity()
anchor.addChild(entity)
arView.scene.anchors.append(anchor)
