Road Editor release

The Road Editor Plugin for UE4 is now available. From November until now we start and finish the first release of a tool which seemed essential to the developers community of Epic Games game engine.

We clearly expect it will fulfill the contract, and see big open games with a beautiful road network, often very tedious aspect of level design, not just in Unreal Engine.

System Requirement

This system requirement is for Unreal Engine Marketplace submission.

• Intended Development Platform : Desktop (Windows, Linux, Mac)
• Intended Platform : All
• Tested Platform : Windows 7 64 Bits, Windows 10 64 Bits
• Working version of Unreal engine : 4.10, 4.11

Installation Guide

Like all plugins, you need to put the folder of the plugin (RoadEditor) inside the plugins folder of your game (YourGameProject > Plugins). Then just start your project, it must enable by adding you a tab in your editor tab. If not, just enable the plugin in Edit > Plugins > Project > Editor.

User Guide

Fallowing control in RoadEditor Mode

• Shift + Left Click = Create a road. You can choose the type of created road in the fallowing picture.

• Ctrl + Left Click
  • On Landscape = Add a spline point. If no road is selected, it will create a road like Shift + Left Click
  • On an other road = Auto Crossover. If no cross is define for that type of configuration, nothing will happen.
  • On a cross = Auto Crossover. Same condition as before.

 

• C = Cut Road. If a road is selected.
• T = Snap road on terrain. It will disable temporarily auto digging and snap spline points (or cross point) on terrain.
• Ctrl + C = Copy Spline. If a road is selected.
• Ctrl + V = Paste Spline. If something has been copy, paste a spline on the mouse location.
• Ctrl + A = Select all. If segment selected, select all road segments. If point selected, select all road points.

Widget Control :

• Transform = Move current selection
• Scale
  • X drag = Tangent strength
  • Y drag = Falloff strength for auto digging
  • Z drag = Nothing
• Rotation
  • Road selected = Turn the tangent direction
  • Cross selected = Define cross rotation

Road Network Configuration Editor

The Road Network configuration is based on the material editor of Unreal Engine.

4 nodes can be add to the graph :

• Basics
  • Road
  • Cross
• Objects
  • Actor
  • StaticMesh

Roads and crosses support sockets input :

• Cross can have both road socket and object socket.
• Road can have object socket

For each socket you have the following attributes :

• name, to improve prototype for your custom road network object.
• socket type, object or road.
• relative location
• relative direction
• enable, if you want the object to spawn by default when the road or cross that own the current socket spawns in world
• normalized, relative to the direction of the road or crossing.

Only for road sockets :

• shift, spawn start, relative to the spline
• spacing, spawn frenquency, relative to each spline mesh component.

All these configurations can be edited in RoadEditor mode
