Hmm...Very odd...the weapons use thruster02-0# or 0#a for the laser cores, which, if you're using the thruster upgrades, should be showing up.
Alrighty, then, I'll toss the texies in question in an updated zip, since I don't know if the 3.5.6 media vp is still hosted anywhere.
These weapons are evolutions of an effect I, er, 'accidentally' made when making some specialized heavy cannons for the Orions in the latest Nodewar iteration. They aren't slated for any campaign, and if people wish to use them, they're free to include in whatever campaign they so desire so long as the composer is given his due.
