r
uses GetDefaultInsideValue() if the object is inside a specific point. =
The
default is 1.0, so converting a scene to an image will result in all th=
e
objects having the same value. Changing this value *should* give object=
s
different output values. I think the colour settings are for visualisat=
ion
purposes only (ie. SOViewer).
