Fixed:
Miscellaneous small bugs
Improved:
Crossing / connections instances in the scene can now be duplicated and reused. This includes customizable dynamic connection instances like X, T crossings and roundabouts

This will start / end the side object at the passed marker index at the start (OffsetPosition.Start) or end (OffsetPosition.End) according the passed value
Improved:
"Combine Sections" for Procedural and Shape sideobject types. In previous versions a single mesh was generated regardless the number of sections defined by the marker active states. It is now possible to generate meshes per section

Changed:
Fixed:
Grass detail objects still visible on roads just on the edge of terrain tiles

Snapping road markers to join two roads at the start and end is now supported. This works by moving the start or end marker over another start / end marker, the other marker will light up. The markers will connect after releasing the mouse button. The road will be closed if the involved markers are part of the same road. The two roads will be joined in one road when there is a match on the road type, otherwise the marker handle will appear in orange and the two roads will connect through an I Connector.

The Snap Connector. These are road type specific prefab connectors that can be added to other prefabs. Scene instances of this road type can be pulled out or snapped to these connectors. This can be used for roads attached to other prefabs like buildings or bridges but also for side objects for which a "road type" is created. For example a gate with walls or fences attached.

Improved:
Combined side objects inheriting the shadow mode of the source prefab
Fixed:
Possibly wrong tangents on the procedural side object type
Changed:
Improved:
Scene View clicks are now only intercepted on objects part of the road network in order to keep it selected. Since clicking the terrain is part of the workflow to deselect markers, double click will actually select the terrain.
Scene View position handle orientation road markers. Previously the position handle orientation was according the path forward. This can be set to horizontal now. Once the position handle is displayed, the W key will switch between path forward and horizontal orientation.
Road shape in terrain splatmap baking, improved smoothness algorythm
Customized road shapes for markers will be preserved when changing the main road width. You will be asked whether you want to ignore the road width change for these markers, reset the width to the new road width, or adapt the shape proportionally to the road width change.
