So I have a Nevada Skies preset that I really love. The problem is after awhile of playing it will switch to another random preset. I have the hotkey set to PGUP to switch it back to the preset I have set but I would like to find out how to make it so that NS stays on the preset permanetly. (if that makes sense)

Any help would be great! Thanks!

What do you mean by "Nevada Skies preset"? I've never heard of such a thing.
Do you mean you want a ENB preset to work with Nevada Skies?

Sorry for the confusing/bad terminology. I mean how when you go into the MCM menu for Nevada Skies and go to Settings there is the option to set a key binding to cycle through the different weather settings. I cycled through them and found one I really love but after awhile it will randomly switch over to a different weather setting by default. I was wondering if there is a way to switch to the weather setting that I like and keep it there without it switching.

If not no biggie its a real simple fix I set the key binding to PGUP so when I notice it switches I just press that and it goes back to the one I set it to.

You have 2 options to achieve what you want.
Either you delete all the other weather types textures and meshes or open the NevadaSkies.ini file and only leave the weather type you want to = 1 all the others, change them to = 0

ini file example:

That makes sense can't believe I didn't think of that! You have helped me so much recently thanks a ton!
