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.

We recommend a max pixel resolution of 16x16k. 32x32k should also work, above that we haven't tested and is really not recommended in terms of performance.

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.

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.

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

• Reimport Objects

  Reimports all imported objects on sync. Disable this to keep modifications made to your auto imported sync objects.

• Reset Placement

  Clears all placement in the scene. Recreates the pcg for detail/instance meshes, refreshes the pointclouds and cleans the detail landscape layer maps used to paint dense objects onto the terrain.
