TES Skyrim SE 0.452

[Anubis]

I found a problem - when looking at a campfire at night, then bottom half of the screen is darker. There is a visible line in the middle of the screen. It moves with the player. I also found out that it is caused by "EnableComplexParticleLights" parameter. Changing values under this parameter does not affect this bug, only thing that helps is disabling ComplexParticleLights.

I'm not sure, but maybe this has been noted before (couldn't find it quickly). I thought it was fixed, because I hadn't seen the bug for a long time.

That’s a billboard glow mesh from vanilla fire, if you rotate the camera you will notice that it will rotate accordingly.

[Anubis]

Even if I don't use vanilla fire ? And how to fix this ?

[mindflux]

Well, whatever that is it probably uses vanilla fire as a base, like most mods do. The only way to address this issue that I know of is to fix the billboard mesh shader properties.

* Do you mean I need to fix the mesh of the campfire ? (I havn't seen this bug on other fires)

* And how to fix the billboard mesh shader properties ? (what are the right and wrong parameters ?)

* Nifskope ?

Yes, there are a few variants of the same object and as far as I remember at least meshes\clutter\woodfires\campfire01burning.nif and campfire01landburning.nif are affected.

Come to think of it, maybe the billboard mesh had wrong alpha properties and used additive blending (flags 4109) but it's been a while so I don't remember for sure anymore. Anyway, that's worth checking first (change to standard, flags 4333).

It's possible that will need to adjust the other parameters as well since changing the alpha property will change how the glow looks visually.

[Anubis]

I tried changing the flags to 4333 but it did not help (meshes\clutter\woodfires\campfire01burning.nif and campfire01landburning.nif)
And no matter which mod I used, even vanilla, the bug is still there.

I even deleted the glow mesh, but still the bug remained. Maybe I tried to fix the wrong files ?

My testing location is Riverside Shack

The glow inside the BSOrderedNode, not the one for the firewood?

The glow inside the BSOrderedNode, not the one for the firewood?

Yes, exactly.

[mindflux]

Hmm interesting... I haven't even launched Skyrim for half a year or so but maybe I can give a try if I can get the game to run again.

EDIT: Well, not sure what you're doing wrong. Deleted the glow mesh from campfire01burning.nif (BSOrderedNode > Glow02), problem gone in that location you specified.
