exrTrader has been thoroughly tested in production by us and our trusty beta testers. The main features of exrTrader are:

• standard LightWave Loader supporting RGBA, does not require a license.
• standard LightWave Savers, supporting all save-able image types except for palletized images, does not require a license.
• a scene type master plugin for setting the image saver options, which are saved in the scene file.
• a dummy saver to enable network render managers to find saved files for success checks.
• an image filter plugin that allows to save arbitrary buffers to a single OpenEXR file that:
  • either uses a custom output file, or the RGB output file defined in the render globals.
  • supports all compression schemes defined by OpenEXR including lossy schemes.
  • supports all output buffers generated by LightWave and exposed through the SDK.
  • supports buffers that may consist of one (i.e. Depth), two (i.e. Motion), three (i.e. RGB) or more channels.
  • offers separate naming options for channels and buffers in the OpenEXR file, this will translate to buffer.channel as defined in the OpenEXR specs. Either may be blank.
  • supports different pixel types per channel.
  • offers the processing of buffers (invert, min, max, scale, offset).
  • supports OpenEXR metadata, including aspect ratio, comments, previews.
  • data window support (for limited region renders).
  • optional un-multiplication by the image alpha
  • advanced preset system with “default” presets and custom preset directories
• network rendering support.
• plugins consist of one file per platform.
• “Q Approved!” and SWELL.
• Support for LightWave 3D metadata.
• Options to customize the export to match a variety of compositing workflows.
• Additionally save single buffers using any image format supported by LightWave 3D
• File and buffer names may contain variables that are replaced with the current values when saving.
• Support for naming the files created by stereoscopic rendering.
• Automatic creation of a data window within the exr files to speed up loading and filters in compositing applications that support a DoD. This is transparent to most other applications.
• A custom image viewer to inspect individual buffers
• free point upgrades, free support, free beer ¹⁾.
