I want to reduce the number of oblivion gates and/or eliminate the red gatestorms. I have tried a couple of mods that claim to do these things but unfortunately they did not work properly. This might be to do with load order. Could someone recommend a mod that does definitely work and do what I want? Thanks once again.

Are you using AN(All Natural) for your weather mod?

Seams thats a problem Check the Thread for AN might not be fixed....

IT was because of the Gate storms Everywhere prompted me to Finish the Main quest..No more gates!!!

This one seems to work for me: http://www.tesnexus.com/downloads/file.php?id=3586

It has a bunch of different options, one may suit your taste.

Showler, that's one of the one I tried which did not work. I don't use All Natural but I do use Atmospheric weather system so perhaps there's a conflict there.

Which of the ESPs did you use?

I think I used two ESPs which greatly reduced the number. I think one of them was called Almost no Oblivion gates. Obviously I didn't use them both at the same time.

There's one in there called: NoRandomOBGatesEVER.esp

It's supposed to set the chance of random gates opening to zero, and close any existing open gates.

It doesn't affect quest specific gates, but I don't think any mods do.

Why exactly are hoping to get rid of them, for perfomance reasons or gameplay? If it's performance there's a very simple solution. Just turn off your refraction shader in your ini file. That shader adds a big hit to your performance when near any gate.
