Element: compound.transparent
Element: compound.transparentnumeric
The selection transparency of the compound primitive. This is a Boolean value (0 or 1). When a compound is transparent (value of 1), a mouse hit on any of its child entities during entity picking is interpreted as a selection of the child. When a compound is not transparent (value of 0), then a hit on any of its child entities is interpreted as a selection of the compound.
Compounds are by default not transparent on creation.
