+Rigid body set to:
+- Active dynamic
+- Axis and rotation locked (linear and angular factor)
+- Trigger/Ghost checked making this a trigger instead of a collision object
+- Force deactivation unchecked to make sure physics engine keep the rigid body active
+- Trigger script checks for overlapping rigid bodies on each update
+
+## How to test
+Move the box around using WASD+QE.  
+When box is overlapping sphere the icoshpere object is visible, otherwise it's hidden.
