exrTrader V1.5a - Windows 32- and 64-bit

Important for Windows users:

The path to the storage of global presets has changed in the Windows version of exrTrader as of version 1.4.1
The new path is: %allusersprofile%/Documents/dbw/LightWavePlugins/

If you want to use previously saved global Presets, please copy them from the installation directory of LightWave to this directory.

The easiest way to transfer them is probably to load the settings directly, once by one, and store them as a global preset within exrTrader.


since V1.5
  • Renamed the loader to "LW_OpenEXR" - please re-add the exrTrader plugin to LW to make it active. This will effectively override the native OpenEXR loader that comes with LightWave.
  • Fixed issues with limited regions and no data window being computed by exrTrader
since V1.4.1
  • Added support for writing OpenEXR data windows depending on the content of the buffers. This decreases the size of image files and speeds up loading and compositing in applications that support the OpenEXR data window (such as Fusion 6, Nuke or Shake)
  • Updated the presets to allow for user defined directories.
  • Added the Pixel Inspector to the VIPER preview,
  • Various minor tweaks, such as adding a dedicated VIPER button the main user interface to toggle VIPER.
  • Minor bugfixes, mainly to the presets system
since V1.4
  • Windows: Moved the location of the global Presets to the documents directory for "All Users" to prevent crashes for non-admin users.
  • Allow users to change the name of the channels saved for single channel buffers (these were hardcoded to Y).
  • This should improve compatibility with Nuke which expects single channel buffers to be named "A" and then loads them as masks.
  • Added the %eye% variable to distinguish images when rendering using a stereo camera
since V1.3
  • Added an option to additionally save buffers a any image format supported by LW
  • Added the ability to include variables in the path name
  • Added an option to apply the display gamma after exrTrader has saved the buffers
  • Updated the manual
  • Added a section to the manual that describes the buffers as provided by LightWave 3D
  • Minor tweaks to the GUI
  • The Reflectivity buffer was accidentally disabled, it is now working again
  • The Depth buffer Minimum/Maximum settings weren't applied as described in the manual, now they are
  • Fixed a (rare) crash bug in connection with the selection of channels and buffers
  • Fixed the quick selection of channels, the Depth Buffer wasn't always added
  • Fixed the behaviour for limited regios, which now match the setting in the render globals

 since V1.2
  • Added support for the refraction buffer inLightWave 3D V9.6
  • Added "flip" option for single channels
  • Added "Luminance as RGB" option when saving greyscale buffers to single images
  • Added a new naming option for output files
  • Tweaked the preset mechanism to allow for longer names as well as names containing "special" characters.
since V1.1a
  • Added display gamma
  • Added gamma correction for buffers
  • Added un-multiply by alpha option for buffers
  • Added LW 9.5 compatible metadata.
  • Added "default" presets
  • various small bugfixes
