Upgrading From a Prior Version

Those upgrading from an older version of LightWave 3D may have a USB hardware key (or parallel key on Windows systems), also known as a "dongle". LightWave no longer requires a hardware key, but you may still find one useful at times (as, for example, if you freelance at a firm with strict network policies).

Otherwise, the same installation instructions apply for an upgrade as for new users. The installation program will not delete any existing objects, scenes, or images on your system unless an existing item has the same name and is in the same directory as an item that LightWave 2019 installs. For this reason, you should install LightWave 2019 in a new directory.

Software Installation

Download and install the most recent version of LightWave for which you have a license here: If you don’t already have an account you can download the trial version found here: and then create one.

Installation Options

After accepting the EULA, you will be asked what type of installation you wish to perform. Choose the Render node entry if this installation is intended exclusively for rendering, rather than creating LightWave assets.

LightWave asks whether you wish to expand the Python runtime library. Users not interested in scripting can ignore this option. The file extensions option is checked by default and should be unchecked only if you are running multiple versions of LightWave. The Network Render Controller advanced options let you choose between an explicitly-launched Task Tray application or a Windows service at startup. The fourth question pertains to how your machine will be identified for network rendering.

Legacy Plugins

LightWave has a long and rich history and many plugins from that history. If you find yourself needing a legacy plugin for resurrecting an old project or similar, you will find a file called in the support\plugins folder.

Running the Program

LightWave 3D is started the same way as any other program on the particular platform on which it’s installed. LightWave 3D has two major applications that work together: Layout and Modeler. Each program can be started independently; however, you may also access them by clicking the appropriate button on their respective interfaces.

In the installation are a pair of icons for troubleshooting firewall settings on Windows 10 systems. The two icons labeled Configure are for tech support use and should only be started at the request of NewTek technical support staff. The LightWave folder will no longer be inside the NewTek folder in the Start menu - it will still be installed wherever you put it. Look for "LightWave" directly.
