I was looking up mods on you tube and i saw something called the dunes. It looks awesome but the video didn't have a download link so i was wondering if anyone else knew something about the Dunes.

if you mean D U N E then yes it is downloadable, but it is completely barren...just sand...sand...sand...and more sand...oh and a rock every once in awhile. It was purposely made that way, it contains a bunch of resources and the creator was hoping for people to create plugins for it, however, I am not familiar with any.

Ofcourse, I am still not sure if you were refering to D U N E or not

I think the Dune mod was abandoned, I can't find a download link at the moment, but you may be interested in http://www.gamesas.com/index.php?/topic/1071663-relzbeta-elsweyr-the-deserts-of-anequina-thread-8/

hmm...wel it might have been abandoned, but I know the download is still available, I saw it just the other day when I was browsing the Nexus...but because of how it is spelled D(space)U(space)N(space)E(space) it's hard to search for that specific mod. You have to dig around a little on the Nexus. I will take a little time to see if I can relocate it for you.

EDIT
god! after long browsing around the Nexus I resorted to google, and ofcourse, the first link that comes up is the Nexus page for D U N E...
here, I present to you, http://www.tesnexus.com/downloads/file.php?id=12218
In the "modder's resource" tab on the Nexus, I came across a guy who made 2 resources for D U N E if you wish to expand it yourself.

another Edit:
if you want those resources here is a http://www.tesnexus.com/modules/members/index.php?id=64650.

Thanks.
