The functionality of the Splines Tab in the Terrain Editor

Splines Tab[]

Splines can be used to create roads, rivers, waterfalls, or variety of other similar line objects with animated textures on it.

To make a new spline, select the desired Spline style from the Presets section then Shift-Left click on the terrain. Subsequent spline sections can be added by Ctrl+Left clicking on the terrain once a start point has been placed. A Spline must have at least 3 total points to display on the map. Spline shape and angle can be adjusted by dragging the spline’s points along the terrain.

  • Presets
    • Search – Search the current list of spline presets.
    • Save/Load – Save your current spline presets or load a previously saved collection of spline presets.
    • New – Create a new spline in the spline presets list.
    • Apply to Selection – Apply the attributes of the preset currently chosen in the spline presets list to the spline that you have selected on the terrain.
  • Preset Parameters – Displays the parameters of the selected spline preset. Certain parameters will only be displayed for certain spline types (such as river or road).
    • Surface - Determines the types of VFX emitted by units which walk upon these terrain items.
    • Dense Water – Texture that will be displayed around the outer edges of the spline.
    • White Water – Texture that will be displayed in the center of the spline.
    • Water Bump – Select the bump texture that will be used for the spline’s water surface.
    • Water Distortion – Alters the magnitude of visual distortion displayed on and under the spline.
    • Water Mask – Red channel of the selected texture that will act as foam in the deep areas of the water.
    • Base Texture – Base texture that will be used for the road spline.
    • Bump Map – Bump map texture that will be used for the road spline.
    • Road Damage – Decorative texture that will be displayed on top of the road spline’s base texture.
    • Width – Width of the spline that will be created.
    • Scale – The scale at which the chosen water texture will be displayed upon the spline.
    • LOD – Level of Detail within which the spline is displayed.
    • Diffuse – Displays the tint/diffuse color of the spline.
    • Opacity – Opacity of the spline.
    • Start – Opacity for start of spline.
    • End – Opacity for end of spline.
    • Spec – The tint/Specular lighting setting for light reflected off of the spline.
    • Specular Intensity – Represents the intensity of light reflection off of the spline.
    • Gloss – Represents how shiny/glossy the spline appears.
    • Scroll U – Speed at which the texture travels towards the start point of the spline.
    • Scroll V – Speed at which the texture travels towards the end point of the spline.
    • Clamp V – Adjusts V position of texture and bump map within the spline.
    • Clamp U – Adjusts U position of texture and bump map within the spline.
  • River Preset Parameters – Adjusts the aspects of the River Preset spline’s animation.
    • Dense Water Scroll Scale – Rate at which the Dense lower water will scroll.
    • White Water Scroll Scale – Rate at which the White water area will scroll.
    • Normal Scroll Scale 1 – Rate at which the first layer of upper water will scroll.
    • Normal Scroll Scale 2 – Rate at which the second layer of upper water will scroll.
    • Distortion Scroll Scale – Magnitude of the distortion displayed upon the spline’s textures.
    • White Water Texture Scale U – Changes the display scale of the upper water layer texture.
  • Track Parameters – Specific settings related to the scrolling of the spline’s textures across the spline path.
    • Preset Name – Name of the spline preset that is used on the currently selected spline.
    • Opacity Edge 1 – Opacity of spline’s edge 1.
    • Middle – Opacity of spline’s center section.
    • Edge 2 – Opacity of spline’s edge 2.
    • Fade Distance – Depth of river spline or similar at which opacity settings begin.
    • Seg. Width – Size of the individual spline segments upon which the texture resides. Similar to spline angle smoothness.
    • Adj Width – Amount to adjust the spline segment width.
    • Control Point – Adjusts the aspects of the currently selected point on the spline and the attached spline section.
    • Z Adjust – Adjust the Z axis location of the selected control point.
    • Width  - Adjust the width of only the segment that lies on the currently selected control point.
    • Delete – Deletes the currently selected control point.
  • Misc
    • Remove Track – Remove the currently selected spline.
