I've started a new mod where you can access both OWB and Zeta for which ever wasteland your in. I've placed a second crashed satellite in "Moonlight Outdoor Cinema. So far I've gotten it all linked up and working properly It uses an edited version of Grib's script from Delay DLC so when you get close to the location you'll get the radio signal.
I'm thinking about where in NV you could find a crashed UFO and access Zeta, Any thoughts?
Mmmm maybe you can enable the UFO from the Wild Wasteland trait to appear even if the player doesn't have that trait and maybe three empty alien bodies nearby (like the raiders killed the aliens from the wild wasteland encounter and looted their bodies) and close to the bodies the teleporter to the Mothership Zeta.
After all with Mothership Zeta DLC playable from within the FNV, requiring the wild wasteland trait to see a couple of aliens in the Mojave desert doesn't sound very wacky.
There is a rather huge plane sitting in one of the deserts (HOW INFORMATIVE); could add the spaceship as a Wild Wasteland event, with the spaceship taking the space where the plane used to be.
Reviving this thread after finding I didn't loose the files. have OWB all set up. does anyone have a clean save at the end of OWB that I could use for testing?
Hey chuck, do you still have the file for this/worked on this any further?
Funny you should ask about it I was working on it last night. 
I love how the main modders here work on such a vast array of useful mods. I'm working on some small ones, but none quite as polished as yours.
