Lightwright is Compatible With Vectorworks 2016, Almost...

Lightwright 5 and 6 work great with Vectorworks 2016, except for Vectorworks’ new Project Sharing feature. It is unlikely that Data Exchange will ever work with Project Sharing.

Lightwright 6.0.4 is Available Now

Version 6.0.4 is ready to download, it fixes a wide range of bugs, including ones encountered when saving and opening .lw4 and .lw5 files, plus some serious ones that caused the Windows version of Lightwright to crash and prevented users from saving show files.

Student licenses require version 6.0.1 or later.


Lightwright Touch vs. Lightwright 6

Unfortunately, Lightwright Touch isn't compatible with Lightwright 6 at this time, but West Side Systems has a new release in beta testing that will, hopefully in about a month. For more information, contact West Side Systems directly.

Lightwright 6's minimum system requirements are the bare minimum you need to run Lightwright 6. Lightwright 6 may creak along with a slow processor or hard drive, and the larger your monitor, the more pixels it has to push. A fast SSD will help opening and closing files, but a fast processor, plenty of RAM, and a fast graphics chip are really needed for a good experience.

I've also found that for some reason the Mac version draws the screen faster than the Windows version. My personal experience has also been that Windows 10 is significantly faster than Windows 7 or 8.

Maybe it's time to consider a new laptop?...;)

Lightwright 6 Needs Serious Horsepower

Using Lightwright 6 with Eos

Eos Version 2.4 is NOT currently compatible with Lightwright 6. They changed the way cue times are sent via OSC, but didn't provide a complete solution for OSC. ETC is working on this and hopefully a solution (and a new version of Lightwright 6 that works with 2.4.1 or whatever) will be available soon.

In the meantime, if you're running Eos 2.3, you'll be intererested to hear that ETC released a new video that shows some of the ways Lightwright 6 connects with Eos.

Lightwright 6.0.5 BETA build 116

Beta build 116 of Lightwright 6.0.5 is ready to download, it fixes the "vicious bug" described above, plus a bug that made counting maintenance lists inaccurate.

This is a public build, but please be aware that is a beta, which means not all of the bug fixes have been fully verified yet.

To download the beta, CLICK HERE.


I've had sporadic reports of show files that couldn't be saved after another file was opened, and the cause was finally discovered today, thanks to a brilliantly complete bug report from Will Dean. The problem only affects Windows users. It turned out that double-clicking a show file to open it caused data corruption in any already-open show files. The fix is done and will be in Lightwright 6.0.5. Until that is available, DO NOT DOUBLE-CLICK SHOW FILES TO OPEN THEM.
