There can only be one markertemplate element in a skin.
The skin is set so that when dragging in nodes from the tour browser thumbnails are produced.
This is done by renaming the markertemplate for the map node markers to "markertemplate_disable".
To activate the markertemplate for the map node markers remove “_disable” from its ID and add it to the thumbnail template ID.
To Make thumbnails add Transformation output to your project.
