MultiBodies

MultiBodies are internally grouped objects. This means that the MultiBody's objects are treated as a single node, but in the viewport you can see the individual objects. Typical examples are → fragmented objects or → object arrays:

Load a SD file via Objects shelf > MultiBody.
You do not have access to these individual objects via a MultiBody's "Node Params" panel – your changes will be applied to all included nodes.
The objects' basic properties are listed under File > Summary Info...
If you want to perform per-object changes right-click on the MultiBody under "Nodes" and choose → "Spreadsheet".
