So, I checked inside the Nevada Skies plugins, with FNVedit, to see what was causing the "blackout" during parts of the day, after a post on the old TTW thread on Nexus implied that merging weather patterns could fix it. I did a bit of tweaking, and the following should help if you absolutely want to use Nevada Skies with TTW, without that nasty blackout bug.(If you're wondering what it is, or haven't encountered it, what happens is, if you're outside during a weather cycle where "High Noon" or "Midnight" is called up, as I'll explain in a moment, the settings, or lack of them actually, for that particular time of day in Nevada Skies cause the lighting to reach RGB values of 0,0,0. True black, of the zero-value variety, is not a dark color, but a complete absence of color, and thus the light isn't just darkened, but completely removed. You can interact with objects and people, and move around, get killed, etc, but the effect basically "blinds" you, and there doesn't seem to be a very user-friendly way of undoing it once it's happened. So, I tried the following, and it worked. I'd love for others to test this out, and make sure I didn't screw something up:
1: Load up FNVedit, with the following plugins, and no others:
FalloutNV.esm
Fallout3.esm
All Fallout NV DLC
All Fallout 3 DLC
TaleofTwoWastelands.esm
NSkies URWLified.esm (Should work with any version of Nevada Skies that you have. I'm using URWLified, because I love the weather settings, night-brightness settings, etc.)
2: Open up your Nevada Skies ESM's "tree," so you see stuff like File Header, Activator, Armor, and so on. The very last entry should be Weather. Open the Weather tree up, and you'll see a pretty long list of FormIDs, EditorIDs, etc. No worries, this is a lot easier than it looks.
3: If you're using FNVedit's default settings, you should see that some of the entries are shaded yellow and red. This is where we're going to fix the blackout. Go through the ones that have red shading, and look through the right-hand part of the window in each one. There are a bunch of columns under the heading, "NAM0 - Colors by Types/Times." Inside those are groups of Red, Green, Blue values under stuff like "Time #1 (Day)" "Time #2 (Sunset)" and so on.
4: Some of these, you'll notice, have values of 0, 0, and 0 for Red, Green, and Blue. Those are the blackout weathers. Notice that they're only like that for times labeled High Noon and Midnight. Those times don't exist for NV's weather patterns, so Nevada Skies doesn't have values for them. This is a somewhat messy fix, and someone better at coming up with suitable values might find stuff that works better than the ones in TTW, but here goes the last step, and the one that will fix your blackouts, hopefully.
5: Go to every instance where TTW has values, and Nevada Skies overwrites them with 0, 0, 0, and copy the TTW values over into Nevada Skies. You can do this by clicking and dragging the values over. Be careful, as it seems there's no "undo" button for FNVedit, so if you mess up, you'll have to either remember what was there if you overwrote the wrong value, or close FNVedit, then launch it again, without saving anything, so you can do it right.(I had to do that once, because my mouse hit a bit of dust or something on my desk. Didn't take too long, thankfully.) If you've done this for every conflicting time period, you'll notice that there aren't any red columns left in Nevada Skies, under Weather. Save your Nevada Skies esm, Open up New Vegas, head to the Capital Wasteland, go outside, and wait at one-hour intervals for an entire 24-hour day. If this worked, you shouldn't get any blackouts, where you normally would with Nevada Skies active.
Good luck, and I hope this was helpful. Sorry for not providing screenshots. I can do that if anyone needs the visual aid. :)
