  • Workflow
    • How do I delete a surface from an object?
      • When an object no longer has any polygons assigned to a specific surface, on reloading of the model (or scene) those unused surfaces will be flushed automatically.

        It can be useful for surfaces to linger while assigning them in Modeler, if you assigned a different surface to the whole model, and the previous surfaces were removed immediately, you would lose them.  Having them persistent within a session allows you to further assign them.

    • Do I need a hardware dongle to run LightWave 3D?
      • LightWave versions 11.0.3 and higher do not need a dongle. These versions can run on a software-based license. LightWave 11.0.3+ can still use a hardware dongle, but it does not require a dongle.

        If the user already has a dongle when upgrading to LightWave 11.0.3+, that user may choose to run LightWave from the dongle or from the software license. If the user has purchased LightWave 11 or higher for the first time, that user will be running a software-based license.

        LightWave versions 11.0.2 and older require a hardware dongle and Sentinel drivers. When buying another user's copy of LightWave, do not purchase a copy of LightWave 10 or older without acquiring the dongle that goes with that copy of LightWave.
