Is there a way to get child of ObjectContainer3D by name?

you may push your children in an array to access em easily

childList.push(child);
objectContainer3D.addChild(child)

you can set the name or other infomation in “extra” property

for (var i:uint=0;i

There is no built-in method to search the scene-graph for objects by name, but you can do a recursive traversal yourself and look at the name property of all the children and their children et c. If you have loaded your assets using the AssetLibrary, you can also find the asset by name through there.

There should be better ways to traverse the display list (including searching by name) and this is something that we intend to add soon, e.g. for Away3D 4.1.
