Just so nobody else has the fun Ive just had :/
Previously was using
var clickMesh:Mesh = new Mesh(new SphereGeometry(earthRadius, 200, 100), new ColorMaterial(0x0, 0.01));
clickMesh.mouseEnabled = true;
clickMesh.pickingCollider = PickingColliderType.PB_BEST_HIT;
clickMesh.addEventListener(MouseEvent3D.DOUBLE_CLICK, tweenToMap_doubleClickHandler);
Now also need
clickMesh.shaderPickingDetails = true
clickMesh.geometry.convertToSeparateBuffers();
To the Devs
dev branch Intermediate_MouseInteraction
head model is missing
geometry.convertToSeparateBuffers();
without it you cant draw on the head model.
