Set here the visual aspect of a direction object.
R, G, B
The
R,
G,
B entries define the direction color,
from black (0.0, 0.0, 0.0) to white (1.0, 1.0, 1.0).
Scale
The
Scale factor can be used to change a direction size, including
its child objects. Direction objects are scaled around the direction center.
The visual representation of an object is always scaled by its own
scale factor multiplied by the scale factor of all its parent objects
until layer, inclusive.
