You can import meshes and animations from Lightwave in two different ways:

  • Using the FBX plugin for Lightwave - Included from version 9.0
  • Importing lightwave scene files using the Lightwave App Link - Included from version 11.0

Unity currently imports:

  1. All nodes with position, rotation and scale. Pivot points and Names are also imported.
  2. Meshes with up to 2 UV Channels
  3. Normals
  4. Materials with Texture and diffuse color. Multiple materials per mesh.
  5. Animations.
  6. Bone-based animations.

Detailed documentation for this from Lightwave is not available on-line but comes in the PDF manual included with your download

Note:

  • Lightwave specific materials need to be baked as textures for Unity to read them - use the Node system in Lightwave for a non-destructive pipeline
  • Unity only understands polygon meshes so convert to polygons before saving/exporting

FBX Export

From Lightwave version 11 onwards the FBX 2012 exporter is now included:

FBX Filename : This file can contain multiple objects, Choose a filename and save to your \assets directory

Anim Layer : TBC

Type : Choose Binary to reduce filesize or ASCII for a text editable FBX

FBX Version Select 201200 from the drop down to ensure version 2012.1

Export : Select all the elements you wish to include - not cameras and lights are not read into Unity

Mesh type Choose Cage Subdivision if * otherwise choose subdivided to *

__Bake Motion Envelopes__TBC

Start frame / End frame

Scale Scene Set a scale for your scene applicable to match Unity

Importing LIghtwave scenes with AppLink

To read a lightwave scene you must use the Applink package provided with your Lightwave installation from version 11 onwards only

Setup

  • Browse to the \support\3rdparty_support\Unity3D folder in your LightWave3D installation
  • Copy LightWaveAppLink.unitypackage into \Unity installation folder within \Editor\Standard Packages folder

E.g. Windows C:\Program Files (x86)\Unity\Editor\Standard Packages (for machines running a 64-bit version of Windows) or Mac: Applications/Unity/Standard Packages.

Create Unity Project for you lightwave scene

  • In Unity create a project e.g. UnityProject_name and check the LightWave AppLink package and any others you require for your project
  • Close Unity
  • Copy or Move your LightWave_Content folder and it’s directory structure into your UnityProject_name\AssetsSave your LWS file in the \assets folder
  • In lightwave make sure your scene file is has it’s content directory set to the new location in the unity project

Your folder structure should look like this:

Unity_Project Assets LightWave_Content Images Objects Scenes

  • Save your LWS scene
  • Open your Unity project

Unity will then convert the LightWave scene to an FBX

  • Select the FBX of the scene and set your scale to 1.0 and Apply
  • Add converted FBX scene to your scene hierarchy
  • Update any Unity materials to set textures and shader types to try and match equivalent Lightwave shaders

Any changes to the FBX (lightwave scene assets) will only be stored in Unity, so this is a Uni-directional pipeline, but Unity will remember any material assignments and properties applied to the FBX scene even if you update from LightWave
