i know what hes on about, orangebox should include episode 2 AND portal content, but it didnt for my server. i had to use GCFScape to extract the contents and add them into my orangebox folder myself. then it worked fine, only issue with the way i did it is that the server cant tell it has the games mounted so it wont recognize it has, but you'll still get all the props and such.
First note, eldar is right, and some people have had to do what DevilsNipple had to do anyways. Gmod's like that... Second note, we plan on releasing all our grids, but eldar hasn't gotten to it yet. Just pester him 'til he does it. XD
