Landscape Spline Import Options

NOTE:

To use the Import Lines as Landscape Splines feature, you must first select a landscape to import the vector lines to – the Import Lines as Landscape Splines button will be inactive (greyed out) until you select a landscape actor.

The Vector Line Import Options window gives you the opportunity to set the parameters for all landscape splines to be created from your GIS vector data. Once imported, you can modify these values for individual control points, segments, or splines by using the landscape Edit Spline tools built in to Unreal Editor.

The Vector Line Import Options window appears when you click the Import Lines as Landscape Splines button (available when you’ve selected a landscape actor) and looks like this:

Information

Source File: The name of the GIS vector line (.shp) file you’re importing.

Assets Path: The path to the folder to use to save any assets created during the import process.

Control Point Import Settings
Size & Location

Spline Width: The width of the spline to be created at each control point.

Side Falloff: The lateral distance at each control point over which the spline will be blended with the landscape (terrain/material).

End Falloff: The distance over which to blend the end of the spline with the landscape.

Snap to Landscape: Whether the splines’ control points should snap to the landscape’s terrain. If unchecked, TerraForm will use z-values of the lines’ points from the imported Shape File.

Control Point Mesh

Mesh: The static mesh object to place at each control point.

Mesh Scale: The scale of the static mesh object being placed at each control point.

Collision Enabled: Whether you should be able to bump into meshes at control points.

Cast Shadow: Whether control point meshes should cast a shadow.

Max Draw Distance: The maximum distance that the control point mesh should be drawn.

Translucency Sort Priority: The sort priority of transparencies in the control point mesh.

Spline Segment Import Settings
Segment Mesh

Mesh: The static mesh object to use for landscape spline segments.

Mesh Forward Axis: The mesh object axis to use in the direction of the spline.

Mesh Scale: The scale of the segment mesh object.

Mesh Vertical Offset: The distance above or below the spline to place the segment mesh.

Collision Enabled: Whether you should be able to bump into segment meshes.

Cast Shadow: Whether segment meshes should cast a shadow.

Max Draw Distance: The maximum draw distance of your spline segment meshes.

Translucency Sort Priority: The sort priority of transparencies in the spline segment mesh.
