"ENB RAIN"

I'm using the original texture option. If this effect is too subtle for you, turn this option off in the Rain section, ENB UI, tweak it, or just disable ENB rain there.

"ENB UNDERWATER"

This effect requires in-game DoF, so the DoF must be turned on in the game settings (But at the same time it's turned off in the enblocal.ini file, because I'm using a great Marty McFly's shader for the DoF effect). Anyway, underwater can be tweaked in two places, in the main ENB UI, you can adjust Tint Amount (adopt this value for the water mod you are using) and Caustics Amount and in the enbunderwater.fx shader, there will find Blur Amount and Range.

"SSE SUNGLARE"

Is set to 0 in the enbseries, If you like this effect, tweak the values.

"ENB SSS - SUBSURFACE SCATTERING"

If you use the "Subsurface Scattering Shaders for Skins" mod, it's time to deinstall it. ENB SSS is based on a diffuse map, so the game sss maps *_sk.dds are ignored by that effect. For this reason, ENB SSS depends on a body texture replacer you are currently using. You should avoid using the default sss maps, they are pink and saturated, better to use dark or even black maps. ENB is ignoring them, but the game engine no, so you can't reduce a red/pink tint effect. Try "UNP Female Body Renewal", subsurface maps "Dark Red" or "Black".
Feel free to fine-tune this effect in the ENB UI.

"SSE LENS FLARE"

This effect Is set to 0 in the enbseries.ini, so you can't see it in the game. If you like it, tweak the values in the [LENSFLARE_GAME] section, in the ENB UI.

"ENB ANIMATED STARS"

This a new enb addon. It's really cool, see my video :

,

Remember, not all the texture replacers for the night sky are compatible with it. With some of them, that effect look just odd when is enabled.
I made my own bitmaps, which works more or less well. They replaces a two textures : skystars.dds and skyrimgalaxy.dds. You can find them in the "Addons" folder, can be installed using a mod manager.
This particular effect should be tweaked individually by the users. To do it, open the ENB UI (shift+Enter), scroll down to the [SKY] section.
There is a one more problem with this effect. It depends on the anti-aliasing method you use. My enbseries.ini is prepared for TAA and my bitmaps. If you use FXAA, or a mod which changes a stars texture, a few parameters need to be tweaked.
Start with a "StarsCurveNight" value, lower it, if you use FXAA, then play with "StarsAnimationDensity" and "StarsAnimationIntensity" until you achieve satisfactory results.

"ENB EDGE ANTI-ALIASING and SMAA"

As you probably know (or maybe don't) in the 0.334 binaries Boris adds a new edge anti-aliasing, in my enblocal.ini, if you use my file, this addon is disabled. I'm personally using TAA and think, that in that case, additional AA isn't really necessary.
But if you hate TAA (this method has a few cons) and prefer to use FXAA, turn it on.
With the latest update I've added an additional anti-aliasing method, SMAA (big thanks for Kingeric1992 and Adyss). Is off by default. To enable it just change the technique in the enbeffectpostpass.fx, see the screen :
PostPass
Only SMAA 1x is available. You can use it as an additional anti-aliasing (but don't know if this makes sense. eats 2-3 frames in my case), or as a replacement for FXAA. One big pros, you can tweak it in the UI. More info you will find in the readme file.

"ENB NIGHT EYE"

The code for the Night EYE effect is made by Phinix - author of "The Truth ENB". He was so kind that allow me to use this code. A huge thanks, Phinix :D
ENB NIGHT EYE is off by default, In the ADDONS directory you can find a special esp files for a normal gameplay and for a Predator Vision mod with prepared enbeffect.fx shader files. Just Copy these files to the proper folders.
To turn it on/off, open ENB UI (shift+Enter}, expand, in the right window called "Shader parameters", enbeffect.fx section, scroll down and uncheck "Use Nighteye Fix".
A bit more of theory, more details and info, how to fine-tune this effect, you will find on The Truth ENB page - - THE TRUTH ENB.
