I found this one: http://www.tesnexus.com/downloads/file.php?id=2581 But the comments seem to indicate that it doesn't work.
Also the wiki provides a number of helpful console commands, but I'm reluctant to experiment on the fears (perhaps groundless) of messing up my current game. http://www.uesp.net/wiki/Oblivion:oblivion_Gates
I don't suppose anyone has any experience with either of these solutions? Or could recommend a mod that I've yet to find?
On a personal level I don't really enjoy spending time in the plane of Oblivion, and based on previous playthroughs after closing the first few they become mind numbingly tedious. Closed gates also create scars on an otherwise beautiful landscape, which I'd prefer to leave unmarred. Usually I just ignore the main quest, but a number of upcoming mods such as Reclaiming Sancre Tor look like they'll require main quest completion before you can progress on them. I've also decided to go with Kvatch Rebuilt instead of Kvatch Aftermath on this install, which I understand requires a certain progression on the main quest before you can fully move forward with the rebuilding.
Any help is greatly appreciated.
