The Marking Curve Tool can be used to place straight or curved markings at arbitrary locations.
Marking curves show up on both road surfaces and terrain surfaces. They use the same linear marking style assets as the Lane Marking Tool.
Although you can create free-form crosswalks with this tool, use the Crosswalk And Stop Line Tool where possible, because crosswalks created in that tool have more semantic linkage to the road topology.
See Curve Editing.
|Marking Style||The Lane Marking Asset or Crosswalk Marking Asset assigned.|
If true, the order of the marking stripes is reversed (for marking types with more than one stripe).
|Start Blend Distance|
If nonzero, the start of the marking is gradually faded to transparent over this distance.
Note that the start is dependent on the digitization direction of the marking curve or road.
This option has an effect only if the material's diffuse texture contains transparent (nonopaque) content.
|End Blend Distance|
If nonzero, the end of the marking will be gradually faded to transparent over this distance.
See the additional comments in "Start Blend Distance".
|Phase Shift||This is used to offset dashed marking types along the curve. This is useful for synchronizing the spacing of dashes where two roads meet.|
|Color||Color multiplied by the material color.|
|Material||Material to use for this marking instance. If set, this will override the material in the Lane Marking Asset. If not set, the marking asset's material is used instead.|
Scale to apply to each dimension of the marking's texture coordinates.
Note that the texture coordinate space depends on the value of the Curve Space Texture option in the Lane Marking Asset.
|Texture Rotation||If nonzero, specifies an additional rotation to apply to the marking's texture coordinates.|
|Texture Offset||If nonzero, specifies an additional offset to apply to each dimension of the marking's texture coordinates.|
|Sort Index||When markings of any type overlap, this value is used to determine which markings appear on top. Given two overlapping markings, the marking with the higher sort index is drawn on top.|
Alternatively, click and drag a Lane Marking Asset or Crosswalk Marking Asset from the Library Browser directly onto the desired marking curve. You do not need to select the Marking Curve Tool first to perform this operation, because it works from any tool. Once done, RoadRunner automatically enters the Marking Curve Tool and selects the changed marking curve for further editing.
