How to reset all enviornment sky settings to one overall setting.

[Whirly Fizzle 4,815]

I presume you are using Firestorm viewer, as you mention Quick Prefs.

In the top menu bar of the viewer, go to Avatar -> Preferences -> Firestorm -> Windlight.

Here you control if region or parcel windlight is applied automatically on entry.

If you want your own local windlight setting to always be used, you must untick "Automatically change environment to use region/parcel settings" and untick "Use Firestorm parcel windlight sharing".
