Best Lightwave with Unreal Engine Cloud Rendering at iRender

From LightWave 3D® 2019.1.4, Newtek introduces support for Unreal Engine 4.23. They will connect with each other via Unreal Bridge. It can be limited to single project use in Unreal, or installed as a general plugin for use in all Unreal projects. The Unreal Bridge will transfer objects, materials and animation from LightWave to Unreal to create a powerful realtime system that can leverage Unreal’s powerful capabilities for presentations, games and more.

How to install the bridge?

In LightWave, Unreal Bridge is a Master Plugin that can be opened from the I/O tab in Layout. To install for the Unreal Engine, you should go to your LightWave install and select the lightwavebridge folder in support/3rdparty_support/UnrealEngine/[version] and:

        • Copy the contents to your Unreal Engine install folder under YOUR_INSTALL_LOCATION\Engine\Plugins\Editor for system-wide access (Users/Shared/Epic Games/UE_4.xx/Engine/Plugins/Editor on the Mac),
        • Or you create a folder called  Plugins in your Unreal project and copy the Lightwavebridge folder there for single project use

Next, you launch the Unreal editor. If you have installed lightwavebridge for single project use, the plugin will be automatically activated. If you have installed system-wide, you will first need to activate the Unreal-side lightwavebridge plugin:

When you restart Unreal after installing the LightWave Bridge plugin system-wide, you will get a message telling you “New plugins are available.” Clicking “Manage Plugins…” you can activate the LightWave Bridge. You can also visit Edit > Plugins to activate. You will need to restart the Unreal engine once LightWave Bridge is activated.

How to use?

1. Unreal

Once installed and activated, you can visit the Unreal Engine preferences and in the Performance tab uncheck Use Less CPU When in Background (this is only necessary to allow the real-time updating between UE and LightWave). If real-time updates are not crucial for your project, you can leave this setting checked and simply Send from LightWave when necessary.

2. LightWave 3D

In LightWave, you can change the color space to sRGB to match with Unreal and go to the I/O tab to launch Unreal Bridge. Start by clicking the Connect button to link LightWave to the Unreal Editor.

Check the options required:

        1. Overwrite options:
              • Overwrite Meshes – will update meshes on the Unreal side
              • Overwrite Materials – will update materials on the Unreal side
              • Overwrite Transforms – will overwrite any transformations made on the Unreal side
              • Bake Animation – will create baked keyframes for all scene animation
        1. Live Sync – Will send updates to Unreal in real-time while you interactively edit in LightWave
              • Items to Sync – Use “Selected” to limit interactive synchronization to the currently selected scene items
        2. Items to Send – Use “Selected to limit the following “Send” actions to the currently selected scene items
              • Send – Send scene items limited by the “Items to Send” selection
              • Send Transforms Only – Sends only transforms of items limited by the “Items to Send” selection
              • Send Animation Sequence – Sends animation envelopes of items limited by the “Items to Send” selection
              • Fetch Transforms from Unreal – this performs a single grab of the current state of Transforms from Unreal to bring them back to Layout

You can start Unreal by creating a new project with no Starter content. Once the editor window is open, you remove everything from it apart from the PlayerStart item to start with a blank slate. Then you change back to LightWave.

You add a polygonal object to your scene in Lightwave and convert its surface(s) to the Unreal material. Now you can send it to Unreal. You can also create keyframe animation for your object and send that through as well, as a separate operation.

There are some notes for you: Changes to animation or transforms will not carry back through to LightWave. Make those changes in Layout to avoid any confusion. In Unreal, make changes that will affect your game or presentation’s code.
