Unreal Bridge
The World Creator Bridge for Unreal Engine allows you to seamlessly import your terrain creations into Unreal Engine for use in your game projects. For version 2.0 of the bridge we have completely overhauled everything about the bridge. It now comes with support for object import using PCG and an auto terrain setup that finds the ideal settings depending on the size of the terrain you want to sync.
Before any operation in the bridge make sure to press the Read XML Data button since that data is required for both the landscape and object import.
Installation
Close Unreal Engine if it's open.
Go to your Unreal project folder and create a folder called Plugins in your project root (if you don't have one already).
Copy the WorldCreatorBridge folder from the unzipped bridge file into the Plugins folder.
The Bridge dialog is located under Window -> World Creator Bridge.
Parameters
XML
In this section you can link your synced terrain. Once you have selected a bridge file press the Read XML Data button to auto import the ideal settings.
Import Parameters
Asset Name
Specify the prefix of the terrain gameobject in the level.
Import Materials
If this value is True, the bridge imports materials from World Creator. Set this to False if you only want to import the landscape and do everything regarding the material. Keep in mind that if Import Layers is enabled you will still get the material layers as landscape layers on your landscape.
Import Layers
When enabled, the bridge will import individual material layers from World Creator as landscape layers and with a blending landscape material. If disabled a single Texturemap will be used for the whole terrain.
Reset Terrain on Resync
Deletes and recreates the terrain on resync. Disable this if you just changed your heights and want to keep existing Edit Layers through the sync.
Landscape Parameters
Section Size
The number of quads in a single section (UE landscape parameter).
Sections per Component
The number of sections in a single component (UE landscape parameter).
Landscape Scale
The scale of the landscape, this influences the landscape and the objects that are imported using the bridge.
World Partition
Enables World Partition for the landscape.
Grid Size
Number of components per landscape streaming proxies per area (UE WP parameter).
World Scale
Number of components per landscape world partition region per axis (UE WP parameter).
Objects
Reset PCG on Sync
Deletes any existing PCG for that Asset Name and creates a new one on sync.
Reset Detail Layers on Sync
Clears the detail layers on the landscape for that Asset Name and sets them fresh from the given data in the sync directory. Disable this to keep modified detail layers.
Reimport Objects on Sync
Reimports imported objects on sync. Disable this to keep modifications made to your auto imported sync objects.
Workflow Example
This example shows how to transfer terrain into Unreal Engine. The Canyon sample file that comes with World Creator will be used. These steps can be applied to any other World Creator project.
Sync from World Creator
Click the sync button in the application bar at the top of the main panel to export all necessary data from World Creator automatically.
Sync into Unreal Engine
To access the Bridge dialog window, navigate to Window->World Creator Bridge.
Configure the bridge parameters to your preferred settings. Press the Synchronize button once you're finished, and the terrain will load into the scene.
