The download contains ZIP compressed files for all platforms supported by exrTrader. Extract the appropriate ZIP file for your platform.


The exrTrader2018.p file can be copied to any directory where you keep your plugins. We recommend using a manually created plugin directory to separate third party plugins from plugins shipped with LightWave 3D. This will simplify upgrades of LightWave 3D.

Now use the Edit Plug-ins panel (alt-F11) of the Add Plugins menu item to add the plugin file exrTrader2018.p to LightWave 3D.

You can also copy it to


to allow LightWave to detect the plugin automatically.


The MacOS versions of exrTrader are included as a DMG (Disk Image). Double click on the icon to mount the disk image.

You can simply drop the exrTrader2018.plugin icon onto the Install application to install it.

The plugin will either be copied to:

Current User installation option:

~/Library/Application Support/LightWave3D/Plugins

or All Users installation option:

/Library/Application Support/LightWave3D/Plugins

In both cases LightWave 3D 9.6 will automatically pick up the plugins once you launch it.

You are of course free to copy the plugin file to another location and add it manually.

Included Plugins

exrTrader is actually a suite of plugins for LightWave 3D. Currently it consists of the following plugins (these are the plugin names as displayed in the Edit Plug-ins window by LightWave):

  • exrTrader – OpenEXR Layered Export
  • OpenEXR Settings
  • exrTraderLoader
  • OpenEXR(.exr)
  • OpenEXR Dummy(.exr)
  • exrTrader…
  • OpenEXR Settings…
  • exrTrader Helper (Pixel Filter, only used by exrTrader Pro)

To be able to use the exrTrader Layered Export you will need to register and activate it with the activation code we will send you after your purchase of a license.

The basic loaders and savers are fully functional without registering.

The last two plugins are convenience tools you can assign to a shortcut, or add to a menu, to quickly apply the respective plugins to the current scene (if they aren't applied already) and open their user interface.


Once you've installed the plugin, apply the exrTrader – OpenEXR Layered Export image filter plugin to your scene, and the registration window will automatically open.

Enter your full name, company name (if applicable) and e-mail address. Export the registration and attach it to an e-mail to registration@exrtrader.com. We will mail you an activation code within 24 hours after payment is received, depending on the time difference 1).

You can now either import the keyfile attached to the activation e-mail, or copy and paste the activation key into the registration panel (please make sure that the personal information is identical to the one submitted to us for the registration).

Your registration is now complete and you will see the interface of exrTrader, allowing you to use it.

The registration file is stored in the same folder where LightWave 3D is installed 2), the license file is named exrTrader.key. If you use multiple licenses of LightWave 3D from a single network share, the registration manager will only append/edit licenses locked to the dongle installed on the host machine. It will however manage multiple licenses allowing for a single registration file on your network share.

Our key generator needs some sleep every now and then ;-)
Please back up your license file if you install a new version of LightWave into the same directory, especially on MacOS.
