How to do it…
Let's start by creating a scene we can use to test our recipes later.
1. Right-click on the
Scenes
folder inside
Project Assets
, select
New
, and then select
Empty jME3 Scene
. The scene will open automatically in the

6. The second icon in the top bar of the
SceneComposer
window is the Move icon.
By clicking on it, you will see three different colored planes by Jaime. These will
