You can select an object by clicking directly on it, or by holding down the left mouse button (LMB) and drag the mouse to creat a bounding box around the object.
If you have several objects, you can chose an individual one by holding down the Ctrl key and left click on the objects. A window will pop up and if you’ve given each object a unique name, or remember what object number Bryce gave the object, you can click on the name and the object will be selected. Select as many objects as you need, then follow The Savage’s instructions.
