QML, Combining multiple meshes into single entity - qt

Question

I am trying to create a customizable Qt3D component by merging three ConeMeshes into a single entity. The user must be able to interact with the custom entity, so I have added an ObjectPicker to the file. Normally, I would use a predefined scaled .obj file, but my manager wants the objects to be drawn directly by Qt.
The two meshes I want to combine are defined in a seperate qml file, so I can call it within my Scene3D.
Entity {
ObjectPicker {
id: combinedPicker
}
ConeMesh {
id: conemesh1
...
}
ConeMesh {
id: conemesh2
...
}
Transform {
id: conetransform1
}
Transform {
id: conetransform2
}
Entity {
components: [conemesh1, conetransform1, conemesh2, conetransform2, combinedPicker]
}
}
My approach for putting the meshes together is to enclose them as components in a separate Entity scope, as shown in the last line. But this approach only renders the last entry in the components array. Above, that would be conemesh2.
Previously I tried to create multiple Entity instances, and pass each one the id of the ObjectPicker,
Entity {
components: [conemesh1, conetransform1, combinedPicker]
}
Entity {
components: [conemesh2, conetransform2, combinedPicker]
}
But as per the documentation of ObjectPicker, the object picker is not meant to be shared by multiple components.
So my question is this: What is the correct approach when merging multiple meshes into one single mesh in Qml?

Answer 1

I solved the problem by "factoring" out the ObjectPicker element, effectivly making it a sibling of the mesh entities.
Entity {
components:
[conePicker]
Entity {
id: pipeTopEntity
components: [coneMeshTop, coneTransformTop, floorMaterialTop]
}
Entity {
id: pipeBodyEntity
components: [coneMeshBody, coneTransformBody, floorMaterialBody]
}
Entity {
id: pipeBotEntity
components: [ coneMeshBot, coneTransformBot, floorMaterialBot]
}
}
