So i am about to mod my Fallout New Vegas and i was wondering if i use Nevada Skies and let's say the Blackout ENB will i still get my Nevada skies effects or will my ENB be be gone and i will be able to only use one?

Im not sure about it as i want a ENB instead of the Nevada Skies clouds but i want to keep to the weather effects.

If your ENB comes with a data/textures/sky folder then it will overwrite the vanilla skies.If I recall right nevada skies does not use the Vanilla names for skies so only the Vanilla sky textures will be overwritten,this means: If you use the Nevada Skies .esp you will still see the Nevada Skies textures (but they WILL look diffrent with an ENB,if you do not like the changes just disable the "Sky" option in your local ENB .ini)
Hope I could help.

wow it was that easy well thanks for the help
