Check out the video on how to install and use the BB Toolkit add-on. The video demonstrates all of the features. 

Some helpful usage tips for BB Toolkit Pro:

THREE LIGHTS SETUP

To add, first select an Object and then click the "Three Lights Setup" button.

How to Rotate all of the Lights at the same time
The Circle you see where the lights converge is the Parent. 
Select that, and rotate it as you please (usually in the Z Axis). The lights will all rotate together. 
This allows you to reposition them to better suit your camera angle and scene. 

Each Light can be moved independently, and will always point towards the convergence point (i.e. the Circle area). This is possible as each light has a "Track To" Constraint assigned to it, each with it's own Empty to track. If you so desire, you can move the appropriate Empty and the corresponding Light will Track it. This means you can point the Lights wherever you like.

RADIAL ARRAY

First, place the 3D Cursor at the location at which the Radial Array will revolve around. For example, at the centre of a Face, elements, or an Object. To do this, make your selection and press SHIFT+S and choose "Cursor to Selected" from the menu.

Now, position the Object you wish to add the Radial Array to. For example, it could be a rivet, which you want to repeat and rotate around a cylindrical object. Place the object (scale, move and rotate as necessary) so that it's at the starting point of the array.

With that done, from the BB Toolkit Pro Modifiers section, select "Radial", choose an Axis to Rotate around, and click the "Add" button.

If you chose the wrong Axis, don't worry, you can change it in the Operator Panel - that's the small options window in the bottom left area of the active Viewport.
