Ygdrasil - material

material derived from ygNode

Description: adjusts the material properties of all nodes below it

notes:

derived nodes inherit all messages from their base classes
see reset method for default settings
shininess accepts values from 0.0 to 128.0 and all others from 0.0 to 1.0
the material property of all children nodes will be changed
use the cache option on child objects to avoid unwanted side effects
