Laser Facility Problem

So, if you don’t know, the laser facility is a VMF.

So, it’s easy, i’ve downloaded it, in that, super VMF pack… whatever, i’ve tried to open in, ERROR there is brushes, so i’ve deleted the brushes, Yaaay so, i spawn it ! yay no problem but, for work, the laser needs a CRYSTAL, so i spawn it and… Rock, yes it’s a Rock, and, you know, it doesn’t work. so, where and why the Crystal won’t work ? or where is it ?
