I am working on RealityKit app project and trying to access a 3D model mesh parts to change their color or to add texture to a specific part of it, I am using usdz and obj format
I tried this code but I get a runtime error
//bring Object from files
let model = try! ModelEntity.loadModel(named: "frog.usdz")
let anchorEntity = AnchorEntity(plane: .any)
anchorEntity.addChild(model)
print("Model is \(anchorEntity.children[0].components[ModelComponent]!)")
// let modelEntity = model.children[0] as! ModelEntity
var part: ModelComponent = anchorEntity.children[0].components[ModelComponent]!
print(part.mesh.contents.models.count)
var List: MeshModelCollection = []
List = part.mesh.contents.models
print("head is \(List["/Head_Roundcube/Mesh"]!)")
var head = List["/Head_Roundcube/Mesh"]! as? ModelComponent
for item in part.mesh.contents.models {
print("item: \(item.parts)")
}
// print(part)
//chenge the color if the object
var material = SimpleMaterial()
material.baseColor = .color(.white)
// model.model?.materials = [material]
head?.materials = [material]
part.materials[0] = material
model.addChild(part as! Entity)
model.generateCollisionShapes(recursive: true)
arView.installGestures([.translation,.rotation,.scale],for: model)
arView.scene.anchors.append(anchorEntity)
there is a screenshot of the error that occurs
and this is the object I and dealing with
and these are the console messages
