ENB light and fire sources obscure the screen when looking a

[Lufi1080]

First of all, sorry for sounding like a robot, I use the google traslator because of my bad English

I have recently installed PRT X - PhotoRealistic Tamriel 10 - Legacy edition but I have encountered a problem which has consumed the last 11 hours of free time that I have had these days, when taking out a torch, approaching any brazier, using a spell of lightning or fire, in all situations the screen becomes quite dark, in some situations such as at night, turning everything black, I've spent enough time messing around with ENB and looking online to end up asking for help directly.

What I have managed to find out is the following:
It is not produced by lighting mods, fire textures etc, I literally only have skyrim installed and the essential patches, as well as the alternate startup mod
when disabling [GLOBAL] UseEfect the problem (along with the rest of the ENB ) disappears but I deactivated and manually changed the values of the rest of the ENB categories lower than this one without being able to locate the culprit, the effect persisting all the time
I am not very clear if it is necessary to attach screenshots, I have not been able to find much information on the problem in question

Adaptation. Tweak the values in enbseries.ini, and if applicable to the preset also in enbeffect.fx, to your liking but note that without adaptation fire sources could become absolutely blinding if they're very bright.

[Lufi1080]

Neither Adaptation nor modifying or deactivating enbeffect.fx solved the problem, after deactivating both, the blackout persisted, the truth is that I no longer know where to go
Still, thank you very much for your help

[mindflux]

By your description it must be adaptation but it can be an external shader as well so I would suggest inspecting the preset more thoroughly.

Another possibility is (modified) vanilla game adaptation. By default it's pretty unobtrusive but like other things it can be modified.

This is what appears, the screen darkening, which does not allow you to see beyond

I really appreciate you spending your time on this

Try this: (create backups of you enbseries.ini and enbadaptation.fx.ini)


1.) Open enbseries.ini with notepad (without starting the game) and under [ADAPTATION] change these values:

AdaptationSensitivity=0.5
AdaptationTime=0.05
ForceMinMaxValues=false
AdaptationMin=1.0
AdaptationMax=100.0


If it's still not working right, then try this additional step:

2.) You need different enbadaptation.fx file for this, it's added to the post. (make backup of the original file and use the downloaded one)
Then open enbadaptation.fx.ini with notepad, erase everything that's inside and put this in: (copy from here and paste into your file)

[ENBADAPTATION.FX]
TECHNIQUE=1
¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤=0
=0
Auto Exposure Bias (log2 scale)=0.0
Adapt Max Brightness (log2 scale)=3.0
Adapt Min Brightness (log2 scale)=-0.4
Adapt Low Percent=1.0
Adapt High Percent=1.0



I had trouble with adaptation (similar to your problem, just slightly different) and after I did all this, problems are gone.

[Lufi1080]

sorry for the delay in answering, by doing all of the above I got two things:
in enbseries.ini the transition between the black tone and its disappearance became instantaneous, but it did not disappear
enbadaptation.fx everything turned black, literally, I could distinguish some flame a couple of angles of the game logo, but everything was black
I do not want to bother with the problem anymore, now my curiosity moves me more, I describe the enbadaptation.fx that I have in case you knew enough to see it with the naked eye, I really wish I had better English and a better understanding of ENB

Are you sure you did everything exactly as described ? It involves 3 files.

1. edit adaptation settings in enbseries.ini (Additionally you could try to change settings under [COLORCORRECTION])
2. replace enbadaptation.fx with the downloaded file
3. make changes in enbadaptation.fx.ini

If you did all this and still have problems, then it's more complicated and involves more files and changes. (This enbadaptation.fx file you have, probably needs some other settings in other files to correspond with it. Very difficult to analyze, many things to check. Need to download this whole preset to diagnose.)
PRT X - PhotoRealistic Tamriel 10 - Legacy edition is one of the more complicated presets, there are 24 files under download section - what exactly did you download and install ?

Also, is this the only preset with this problem, have you tried other presets ?

[Lufi1080]

Yes, I am totally sure that I did everything as described, it was really explained very well and I could easily see that I had to edit the 3 files.
I use the litel version of the ENB, as far as I understood, it was only necessary to enter the file in question, I tried to change the version to the normal version, but as you say, it was too complex and if the black screen appeared, I imagine it would be late or early I'll go to another ENB, but now, after so much time browsing between ".ini" it really kills me curiosity, the most that I have achieved with repeated trial and error has been to relate the problem with enbadaptation and discard ADAPTATION (which is why I see it is used to mark the transition between light sources, or so it has seemed so far)
I am aware that this is becoming very reckless, and I do not want to bother more than necessary, if as you say, this would require much more investigation of additional files, I think everything would become too exhausting for the forum.
Even so, I suspect, thanks to your comment, that I have not downloaded everything that I should have downloaded, that is, I know that the normal ENB version is modular, and more things have to be added, but it was not clear if the litel version shared this similarity and just download that, the litel version, its file as such, following the installation instructions

As I said, now I'm just curious, because more people have had this problem but no one ever seems to find the solution.

[Lufi1080]

I'm still working to find the problem hahahaha
