SSE shadow question, just an engine problem?

[Kossu]

So while playing my modded sse, I have been noticing some texture shadow problems popping out here and there where a light casted from a torch or candlelight spell would not apply to textures until standing literally on top of that said texture. ( Also using beth ini)

 

And to clarify after these problems started bugging me enough I tested it with unmodded, vanilla inis(on ultra), no added textures and the problems still occur. I have noticed that this problem occurs on few places, especially notorious are roads where multiple different textures are present. One place where this occurs is just at the riften entrance when you are inside the town on the right, this is with using candlelight.

 

https://imgur.com/a/yq3HX   here you can see said place in Riften, where the darker "shadow" is the line where basically the textures meet but light is not cast to the other texture.

 

So as I started doing some detective snooping, but could not find a reliable answer. Is there any known fixes to this lighting issue or is it just engine limitation?

 

And apologies if I posted in the wrong forum section!

I've played through about 12 levels in SSE and have not noticed this. I'll test it when I can to see if it happens on my end.

Its an odd issue and happens quite randomly(always at night time tho), I have noticed it few times in random places at random times. Sometimes I can replicate the results, and sometimes I cant. I would assume at this point it would be an engine issue with lights just going ham.

 

One of the best examples is this when you arrive at morthal around 12-5am and the npc event triggers, their torches illuminate the textures like its pure daylight and while their torches do that I could not replicate this with my torch nor candlelight. https://imgur.com/a/F6kH3  ( you can also see at the pictures that guard torches wont cause the issue to the tiles, and once again just pure vanilla sse. But it does occur on modded/textured games too )

I have also noticed same things happening at whiterun stables and whiterun entrance sometimes. 

 

Its just really odd, but then again its skyrim lights

Yes, I've confirmed the issue myself. It can easily be seen at night in Riften. Simply go through the gate behind Helga's Bunkhouse and around the corner to see it on both sides of the alley. Once you focus on it, the light "pops" on. This behavior is nearly identical to meshes being overloaded with light sources causing them to not be illuminated, but this is the exterior we're talking about. I'm wondering if Bethesda's new lighting is causing this issue. I doubt that it can easily be fixed unless changing a setting somewhere will do it. That would take a ton of testing, though.

 

Edit:

I've done a lot of testing on this. So far...

• I believe the issue is with the RTLandL01 mesh because you get hard lines as shown in the image below when you go one level deep when hiding it in the CK. This looks just like it does in the game when shadowed, but reversed. Meaning the land next to the building is shadowed and the path is lit.
• It's not caused by any shader on the land mesh as I disabled and tested them one by one.
• It's not caused by the buildings because I disabled those via the CK and the issue was still there.
• It's not caused by an overload of lights hitting the mesh because there are no lightbulbs in that area.

I don't know what else to try. Right now, it looks like some sort of vanilla bug.

Interesting stuff.

Interesting stuff.

Just skyrim stuff xD

 

But anyways thanks akatosh for confirming this!
