2026-03-19T01:47:33  <OpenMW-bridge> <cmaugust> ye
2026-03-19T01:48:23  <OpenMW-bridge> <cmaugust> And I thought that was the reason classic falloff is stupid.
2026-03-19T01:48:57  <OpenMW-bridge> <cmaugust> Because it needs every light radius to be enormous to work.
2026-03-19T01:49:39  <OpenMW-bridge> <cmaugust> I thought Capo worked it out to something like hundreds of meters
2026-03-19T01:49:59  <OpenMW-bridge> <Good Eye> right which means light culling doesn't actually exist
2026-03-19T01:50:08  <OpenMW-bridge> <Good Eye> every light effects everything
2026-03-19T01:50:13  <OpenMW-bridge> <cmaugust> And it won't even look nice unless they were also getting occluded by shadows
2026-03-19T01:52:45  <OpenMW-bridge> <cmaugust> If there's evidence of any other game using that "realistic" vanilla falloff I don't know about it
2026-03-19T01:54:34  <OpenMW-bridge> <wareya> iirc, morrowind.exe primarily uses inverse linear (1/x) falloff. which WOULD be physically wrong, but it does the calculations in gamma-compressed sRGB, so in terms of physical photons coming out of your monitor, it's more like (1/(x^2.2)) falloff.
2026-03-19T01:57:18  <OpenMW-bridge> <wareya> "physically correct" falloff in terms of individual photons is 1/(x^2).
2026-03-19T02:01:08  <OpenMW-bridge> <cmaugust> Did you have the number for how big a (for example) a "64" radius light would have to be?
2026-03-19T02:06:13  <OpenMW-bridge> <wareya> no idea
2026-03-19T02:06:30  <OpenMW-bridge> <wareya> modern games makes lights fade out after X units and make it controllable on a per-light basis separately from how bright the light is
2026-03-19T02:09:10  <OpenMW-bridge> <Good Eye> i'm just gonna turn the light bounds multiilier into a radius multiplier
2026-03-19T02:09:31  <OpenMW-bridge> <Good Eye> and if you want old look you stick to compatibility mode
2026-03-19T02:12:56  <OpenMW-bridge> <cmaugust> Sounds good
2026-03-19T15:15:58  <OpenMW-bridge> <Joe> Anyone have any advice with Rafael's shaders? I just installed it for the first time and I'm noting in places like in the Ald'Ruhn manor district light sources get stronger/weaker as I move around. Like if I stand still the lights are static, but if I start walking towards lights they will start glowing stronger. I tried enabling unlimited light distance but it didn't change anything
2026-03-19T15:30:34  <OpenMW-bridge> <Joe> Example, see how the lights just pop-in?

2026-03-19T15:32:07  <OpenMW-bridge> <.hemaris> what have you got your light limit set to? in the in-game settings, in the Lights tab
2026-03-19T15:32:53  <OpenMW-bridge> <Joe> https://cdn.discordapp.com/attachments/718892786157617163/1484213069570637965/image.png?ex=69bd68a3&is=69bc1723&hm=3487051495229cde5523d29eaf9527c6724bc77e263f902f92bb34516d3505b8&
2026-03-19T15:33:31  <OpenMW-bridge> <.hemaris> okay. does this also happen in other cells? or just Ald'Ruhn, Under-Skar
2026-03-19T15:34:19  <OpenMW-bridge> <.hemaris> i ask because that particular interior uses a single omegahuge mesh for the whole building, which means it is in range of every single light in the cell
2026-03-19T15:35:08  <OpenMW-bridge> <.hemaris> and i haven't counted, but it seems like there a lot of added lights in there from your modlist. like, potentially over 64
2026-03-19T15:35:42  <OpenMW-bridge> <abdu7944> Isn't that just post processing light glow?
2026-03-19T15:36:14  <OpenMW-bridge> <abdu7944> IIRC Rafael's light glow has bad pop-in
2026-03-19T15:36:19  <OpenMW-bridge> <hangon3415> when the cell hits the light limit this pop-in things starts happening with post processing shaders. i guess that the lights stop getting taken into account
2026-03-19T15:36:45  <OpenMW-bridge> <hangon3415> that ald skar cell probably has more than 64 lights in it
2026-03-19T15:36:51  <OpenMW-bridge> <abdu7944> Try Zesterer's light glow
2026-03-19T15:37:06  <OpenMW-bridge> <abdu7944> It works better than Rafael's.
2026-03-19T15:37:08  <OpenMW-bridge> <hangon3415> openmw doesnt have mesh light limits iirc
2026-03-19T15:37:21  <OpenMW-bridge> <hangon3415> the pop in will happen with zesterer’s too, though
2026-03-19T15:37:29  <OpenMW-bridge> <.hemaris> yes it does, it's set to 64 right there in the screenshot
2026-03-19T15:37:30  <OpenMW-bridge> <abdu7944> Not this bad
2026-03-19T15:37:42  <OpenMW-bridge> <S3c:tor> We do have the limit, it just tends to be higher.
2026-03-19T15:37:48  <OpenMW-bridge> <abdu7944> It didn't happen in places where Rafael's did jave pop-im for me.
2026-03-19T15:38:47  <OpenMW-bridge> <hangon3415> ok maybe im getting something wrong
2026-03-19T15:39:10  <OpenMW-bridge> <abdu7944> All lights in that room work, from a glance its post processing light glow.
2026-03-19T15:40:12  <OpenMW-bridge> <abdu7944> Its limit IIRC is 54 lights btw.
2026-03-19T15:40:29  <OpenMW-bridge> <abdu7944> And it doesn't do the same order as regular IIRC?
2026-03-19T15:41:18  <OpenMW-bridge> <abdu7944> At least it has some sort of culling in comparison to regular lights.
2026-03-19T15:43:10  <OpenMW-bridge> <Joe> I'm reading through the chat, I see lots of interesting information here. I looked at Zesterer's shaders, would it be possible to use Zesters light glow with Rafael shaders? I see the mods are structured different with Rafaels using post processing & Zesterer's overrides core shaders
2026-03-19T15:43:23  <OpenMW-bridge> <abdu7944> Try it.
2026-03-19T15:43:37  <OpenMW-bridge> <abdu7944> Disable Rafael's first.
2026-03-19T15:43:42  <OpenMW-bridge> <abdu7944> Its optional
2026-03-19T15:48:57  <OpenMW-bridge> <abdu7944> Instead of that, you can also play with the light glow settings.
2026-03-19T15:49:06  <OpenMW-bridge> <abdu7944> The radius...etc.
2026-03-19T15:49:22  <OpenMW-bridge> <abdu7944> There should be some configurables to that effect.
2026-03-19T15:50:24  <OpenMW-bridge> <hangon3415> yeah, for less noticeable pop-in you can make the point glow smaller
2026-03-19T15:50:47  <OpenMW-bridge> <hangon3415> although i personally do like the huge glow orbs around lights
2026-03-19T15:59:01  <OpenMW-bridge> <abdu7944> Wait its actually lower than that? https://gitlab.com/OpenMW/openmw/-/merge_requests/1928/diffs#e951911d0825d7245612cb63a08558a69b705073
2026-03-19T16:00:49  <OpenMW-bridge> <abdu7944> What was limited to 54 then...Why is that number in my head
2026-03-19T16:02:56  <OpenMW-bridge> <abdu7944> @Good Eye Is there a reason sMaxPPLights is set to 40 and not at least higher or closer to regular lights Max Lights?
2026-03-19T16:03:45  <OpenMW-bridge> <abdu7944> Was it for performance?
2026-03-19T16:03:46  <OpenMW-bridge> <Good Eye> it's just a uniform array so there is a limit in size

2026-03-19T16:05:34  <OpenMW-bridge> <Good Eye> well with clustered there is indeed a buffer of every single light...but i'll leave that as a task to use that buffer instead of the compatibiltiy one for someone else :todd:
2026-03-19T16:05:44  <OpenMW-bridge> <Good Eye> well almost, it's frustum culled
2026-03-19T16:11:17  <OpenMW-bridge> <.hemaris> annoying feature that nobody would actually enjoy request: point glows from lights outside the frustum remain visible and make it hard to see through the glare
2026-03-19T16:11:48  <OpenMW-bridge> <.hemaris> "it's just like not being able to see shit under bad lighting conditions in real life!"
2026-03-19T16:12:38  <OpenMW-bridge> <Good Eye> you can already do that with Lua binding
2026-03-19T16:14:25  <OpenMW-bridge> <Good Eye> or I guess we can just expose all the lights with its own buffer, anyways seperate task

2026-03-19T18:36:22  <OpenMW-bridge> <maxyari> reading it it doesnt really look like it will do the thing from that video you posted, but im not sure, its just simpler than i expected
2026-03-19T18:39:52  <OpenMW-bridge> <maxyari> @vtastek there's barely any difference between grass shader in there and in current openmw, grass vertex shader that is, im quite sure it will not look like the video you shared
2026-03-19T18:39:55  <OpenMW-bridge> <maxyari> im so confused
2026-03-19T18:39:58  <OpenMW-bridge> <maxyari> can you elaborate?

2026-03-19T19:33:04  <OpenMW-bridge> <maxyari> this looks different though, or am i crazy?
2026-03-19T19:46:03  <OpenMW-bridge> <liammellofarley> https://github.com/liammellofarley/openmw_terrainnormals This is what I did to enable the terrain normal map blending, I'm assuming the reason something like this hasn't been done before is because I'm not doing any normalization afterwards? With how bad the normal maps for terrain in post are now I think even if they break sometimes this is an improvement. I just set it to write all normal maps instead of just the
2026-03-19T19:46:04  <OpenMW-bridge> last normal map and then changed the terrain blend func to make it so you the blend averages instead of additively stacking. The normal blending should be fine without that but it lets you boost opacity in terrain.frag based on the heightmap to do a really simple heightmap blend, in vanilla it makes things brighter if you do that because of the additive blend.
2026-03-19T19:47:48  <OpenMW-bridge> <liammellofarley> It blends as stupiddly for normals as you'd expect but for stuff like wetworld the weird blend area normals still look better than the vertex normals imo

2026-03-19T20:01:48  <OpenMW-bridge> <vtastek> needs a little tweaking to be better.     float gtime = time * 0.5 + 1000 * bnoise(worldpos.x + worldpos.y + 0.001 * time);      float fi = 0.5;     float cg = 16.14;     float bi = 16.0;
2026-03-19T20:02:28  <OpenMW-bridge> <vtastek> distant land  on/off triggers shaders recompilcation in MGE. you can setup a macro for it through mgexegui.
2026-03-19T20:03:41  <OpenMW-bridge> <.hemaris> the only tricky thing about that command is that you have to use the region ID, which is sometimes a string you've never seen in-game. like when you go to a wilderness cell and it says "Molag Amur" in the corner of the screen, you have to write Changeweather "Molag Mar Region" x

2026-03-19T23:15:29  <OpenMW-bridge> <Good Eye> 4.1 has no compute shaders 😥
2026-03-19T23:18:02  <OpenMW-bridge> <Good Eye> I have a build but I feel like there's compilation errors on windows
2026-03-19T23:18:13  <OpenMW-bridge> <Good Eye> anyone wanna volunteer to check it out and try and build
2026-03-19T23:18:52  <OpenMW-bridge> <Good Eye> wait that is clustered? it doesn't make sense, why are some objects not shaded?
2026-03-19T23:20:55  <OpenMW-bridge> <vtastek> no, just brute force.
2026-03-19T23:21:03  <OpenMW-bridge> <vtastek> I have to go clustered.
2026-03-19T23:21:04  <OpenMW-bridge> <Good Eye> I also just went ahead and removed LightModel and rely on sun ambient like we should, so that's one less piece of FFP state
2026-03-19T23:21:06  <OpenMW-bridge> <Good Eye> oh
2026-03-19T23:21:16  <OpenMW-bridge> <Good Eye> well I just copy-pasted the binning shaders 😁
2026-03-19T23:21:44  <OpenMW-bridge> <vtastek> I have to do it without compute 😄
2026-03-19T23:22:04  <OpenMW-bridge> <Good Eye> openmw probably should to for compatibility but I don't feel like it
2026-03-19T23:22:29  <OpenMW-bridge> <Good Eye> I added frustum culling CPU side, i beleive it's necassary
2026-03-19T23:23:50  <OpenMW-bridge> <Good Eye> something something simd
2026-03-19T23:23:57  <OpenMW-bridge> <cmaugust> hello
2026-03-19T23:24:09  <OpenMW-bridge> <Good Eye> sorry I have no way to build on windows, I opened a draft
2026-03-19T23:24:46  <OpenMW-bridge> <cmaugust> Oh cool
2026-03-19T23:27:24  <OpenMW-bridge> <Good Eye> I mean translating it to C++ is easy part, but making it just as fast is the hard part. obviously the culling bit since you only need to do the clusters once per view and then again if fov/screen res changes, etc...
2026-03-19T23:59:44  <OpenMW-bridge> <cmaugust> oh uh
2026-03-19T23:59:51  <OpenMW-bridge> <cmaugust> looks like the builds failed?
