Changing the opacity of all features on an Ortelius’ Mapping Layer is now easy as pie. Unlike the master opacity of individual styles, changing a Mapping Layer’s master opacity affects all features and respects the object stack order within the layer.
Program : Ortelius 10.9.8+ for Mac OS X
Topics Covered: Mapping Layer, Opacity

In the lower left Layer sidebar, click the ‘+’ to add a new Mapping Layer. Add features to your map as desired.
With the Mapping Layer active, choose Layer > Attributes… and adjust the Opacity slider. Note, this feature is currently limited to the Mapping Layer layer type.
