✅Luma: Unreal Engine

[azure hedge]

how do I use Luma with SK ?

I see were I put the addon in SK folders

no pb there

but where do I put the rest ?

Does it work if I put the rest in game folder ?

let's see...

he...

I'm not even getting any reshade addons

[rancid mango]

Good luck getting it to work, I can't say I've tried with luma specifically, but I've never been able to get the depth buffer working in reshade when using it as a special k a plugin (which luma also needs), I'd love if it was possible as SK's frame limiter is awesome

[topaz belfry]

just use DC

[rancid mango]

DC?

[topaz belfry]

Display Commander

is a reshade addon

[rancid mango]

This looks interesting, I'd not heard of it. Will have to have a play, thank you.

[solar mountain]

are those settings correct to disable luma HDR part? gotta use reno for hdr, so was wonndering if just turning off luma hdr is enough, or i need to change something else?

[solar mountain]

@topaz belfry @azure hedge Please, is this correct?

[rapid saffron]

You unchecked it, you're good. Just use Reno now alongside.

[azure hedge]

Yes that's it. Just got to restart to apply

[red heath]

and don't think too hard next time 🤣

[solar mountain]

hmmmmm, im sort of getting crash, when i open reshade ui, and change settings on the reshade, seems not crashing on reno menu, strange behaviour

[solar mountain]

i have to, this games is so sensible with luma. on ff7 remake works pretty much without a flaw, not a single problem, just straight up works.

[topaz belfry]

just silent crash?

[solar mountain]

This One, game crash with fatal error

[topaz belfry]

just fatal error, nothing else?

[azure hedge]

TOA ? I don't have this pb. Are you running DC ?

[solar mountain]

yep, strange never happened. also ff7 remake just doesnt cloose properly, and i have to stop from steam game page, but i think it was always like that.

[solar mountain]

nope, waiting for pmnox to get a stable release

just luma + renodx hdr on tales of arise, TAA only with your settings, which look pretty nice

[topaz belfry]

yeah I don't know why that happens at all

[solar mountain]

i think since im testing a few things, at some point, i really believe my stupid nvidia driver just get corruption. last time, everygame was just crashing with reshade if set on DXGI hook method. lets see, i will try reclean my drivers again and see what happens. btw, now also rebirth was getting stuck and had to stop on steam game page lmao. and i just have reno dx on rebirth...

[solar mountain]

somehow rebirth fixed, idk how, just reinstalled last build. Luma now seems to work, but i think it crash when i try changing nits on reshade overlay, or sort of. instead, ff7 remake doesnt kil it's process, and have to press stop on steam game page still. tryed both nexus build and latest build hmmm

is there something luma or reshade itself save somewhere on %localapp% or registry, idk. maybe its something left from past usage, that conflict

[topaz belfry]

there shouldn't be anything except the reshade.ini

[solar mountain]

not a big issue anyway. and Prolly on arise also i need to reinstall to clear that bug. i might just send log on reshade discord, and see what came out

[solar mountain]

@topaz belfry idk if it can help, already posted on reshade discord, waiting for an answer. but i found a difference.
ff7 rebirth using reno, exist like this:

it miss the whole exit sequence

[solar mountain]

@topaz belfry clean reinstall fixeds everything, now im not getting the crash changing hdr overall setting on reshade, so idk.
Everything seems working, just FF7 Remake on dx11 using Luma, doesn't stop correctly.
Tryed with just reshade, and it close correct. Just luma make the game process hang on close, as it doesn't unhook reshade

for comparison
Tale of arise Luma+Renodx

FF7 remake Luma
12:43:25:363 [23644] | INFO | Redirecting IDXGISwapChain::SetFullscreenState(this = 000001B2D47054A0, Fullscreen = FALSE, pTarget = 0000000000000000) ...

[azure hedge]

If Tales of Arise is still crashing the only thing I can tell you is to maybe make sure you've not got anything overriding your windowed/fullscreen mode. The game doesn't like it much and it will crash when combined with renodx. Be sure you haven't got anything of the sort in Nvidia driver profile or AriseSDK/engine.ini. Make sure AriseSDK has "resolutionfix" set to false and you don't have something like "screenresolution=2560×1440f" in your engine.ini.

[solar mountain]

actually im using it again, if you mean
; EnableResolutionFix: whether or not this should prevent game from switching to fullscreen 720p on startup
It does a crazy startup stuff whitout idk what exactly, but setting r.SetRes=3840x2160wf does make it work. i tried both in the past, i think with the fix it's more straightforward.

also atm arise should be good, and i told reshade about that bug, noone still answered me.

but, today i couldnt reproduce it again, so idk lol

Luma on ff7 remake process hanging after closing still an issue tho. atm everything working apart that

[topaz belfry]

I have had other people report this issue. But I am not sure what causes it.

[solar mountain]

Ok. i posted the logs on reshade #help, specifically saiyng reshade+luma, but also saying arise unreal luma, is not affected tho.
Dunno how many luma mods are affected, but FF7 remake one is. let's see if i can get a response or help possibly. The fact i'm not the only one, narrow down the compatibility of like, my setup, my graphic card or simple nvidia driver. If its happening to more ppl, is it only ff7 remake or other luma plugins, might be reshade related. some sort of compatibility with what luma does in that type of game, or games. if you could strenght my post asking info, maybe they could give some insight, since i'm pretty newbie on their discord 😂

[topaz belfry]

I have been a bit busy lately, so can't check atm

don't think it is an issue to be brought up to reshade unless it happens without luma loaded as well

[solar mountain]

oh i see, check this one

can it be that? that error of effects

https://cdn.discordapp.com/attachments/1429954416781557872/1486695069149827132/ff7remake__2026-03-26_12-42-48_163_Overlay.png?ex=69c6702d&is=69c51ead&hm=ec4c9853580c9ac6da34401030c08d76006c7873738ad7a8855672edee6eb3c6&

[topaz belfry]

no

not really an issue

[solar mountain]

k

[topaz belfry]

likely to do with code and me not cleaning up some resource correctly

[solar mountain]

oki, sorry for the trouble ❤️

[rancid mango]

Out of interest, did you get Tales of Arise working with DLSS at any resolution other than native/DLAA? not a big issue of course, it's still WHAY better than the native TAA, but I find either using the in-game resolution option or using r.ScreenPercentage= anything other than 100 in the Engine.ini reverts DLAA back to the UE4 TAA

[topaz belfry]

this is not trivial to do unfortunately

[rancid mango]

Not a problem at all ! The fact you manage DLSS injection into non-supported titles as it is already wizardry that mere mortals like I can but admire from afar

[calm pivot]

Hey guys. Can Luma be used alongside Optiscaler?

[topaz belfry]

yeah it can

[quasi geode]

Hey does anyone know how to get rid of the statistic overlay stuff at the bottom left corner?

[topaz belfry]

you must have used some tool to enable it. if you have dlss swapper you can disable this in the options

[quasi geode]

Awesome that worked flawlessly, thanks man.

I also have another question is there a way to up the resolution with the in game scaler? When I attempt to do that it now makes the game blow up and scales incorrectly.

[inner island]

Maybe try DLDSR if you want downscaling

[quasi geode]

I wouldn't be able to upscale to 5120 x 2880 for instances in DLAA?

I'm sorry I probably don't understand exactly what you're saying 😓

[topaz belfry]

not supported currently

requires resolution to be the same as monitor

[void hull]

Doesn't that mean things like DLDSR might work?

[topaz belfry]

you probably have to set your desktop resolution to dldsr

but not sure

[void hull]

That's what I meant so yes you'll have to do that

[hallow tusk]

something strange happens when I use Luma with Guilty Gear Strive, if I use DLSS upscale the image is zoomed it, but only during matches, its fine in the menus. 😞

[eager crypt]

Hey guys，is Luma HDR ready？

[red heath]

no

[topaz belfry]

WIP on that front

[topaz belfry]

Upscale is not supported by Luma. Is Strive unreal engine?

[pastel frigate]

Any luck for the mod working with trek to yomi and days gone?
I know days gone taa is different but trek to yomi uses standard ue4 taa i guess

[hallow tusk]

yes, strive is unreal engine 4

[topaz belfry]

and it has a resolution scale setting in game?

[hallow tusk]

yes

[topaz belfry]

would be a decent game to test upscaling, but don't own it

[hallow tusk]

with super resolution set to none its works fine but using dlss or fsr3 it zooms in the image during matches. Also HDR works but has a lot of issues like characters not showing during character select etc.

[topaz belfry]

try setting to autohdr only?

but likely a resource upgrade issue

[red heath]

pls update the wiki if you try a new game, whether it works or not:
https://github.com/Filoppi/Luma-Framework/wiki/Mods-List#unreal-engine
thx!

[stuck ivy]

does anybody know how to make bl3 dlss work? it shows dlss but enabling does nothing playing on steam

[red heath]

check wiki above.

[stuck ivy]

tried everything but it wont work for me

[topaz belfry]

Huh really? Bl3 was one of the games I tested most. I can check again

[red heath]

wiki says it don't work

[stuck ivy]

DLSS works for other users in this Discord even if wiki says it doesnt work

but idk

[topaz belfry]

Must have been some regression at some point, I'll check

[stuck ivy]

thxx

[prisma fulcrum]

Are you talking about Borderlands 3? I know that egs and steam version have slightly different configs, some mods aren't work cause of this. Maybe thats the case here.

[prisma fulcrum]

Anyone allowed to do this? I tested Ancestors: The Humankind Odyssey today, it works perfect without any additional tweaks.

[red heath]

Yes

[prisma fulcrum]

Also made config for it

[topaz belfry]

Not sure if there is space for the entire config. But looks pretty good

[prisma fulcrum]

I also checked What Remains of Edith Finch and added it to the list. This is currently the oldest version of UE4 with working DLSS on the list. I'm surprised it works; your work is excellent. I knew TAA could be replaced with DLSS, but I couldn't imagine it could be so unified.

[topaz belfry]

few games shipped with UE4 versions older than 4.9

so most games are supproted as long as they use unmodified UE4

I can add support for the rest but have been lazy

[prisma fulcrum]

You mean DX12 or modified UE4 like Days Gone?

[topaz belfry]

I meant for games that use UE4 versions older than 4.9 or so

I think Street Fighter 4 might be one, but not sure if it's vanilla UE4

Days Gone is custom

[prisma fulcrum]

Do you happen to know if it's possible to fix the animation rate in UE games? It looks suspiciously generic in lots of games, skeletal meshes just go 5 fps at certain distance from camera. So i suspect it may be UE default URO preset or sth. But i never see it being fixed outside two cases - Atomic Heart have custom cvar for it and Satisfactory devs actually change default behavior and implement in game settings. The saddest thing is that the Satisfactory example shows that the CPU performance gain from the default approach is simply laughable.

[topaz belfry]

have you asked the people in U+ they know about all the weird engine variables

maybe @red heath also knows, he read all the UE code

[prisma fulcrum]

I didn't ask, but i think its worth trying to find out

[marsh quail]

URO is most likely a console optimization where specs are more constrained
PC can blast through it easily

[pastel frigate]

in trek to yomi dlss is greyed out

[topaz belfry]

did you copy the nvngx_dlss.dll to the right place?

[pastel frigate]

yes

[topaz belfry]

and FSR3 works just fine?

weird

[pastel frigate]

fsr3 works but gives me jaggies

[topaz belfry]

send me log?

[prisma fulcrum]

If fsr works you can swap it to dlss using optiscaler 😂

[pastel frigate]

fsr shows to be working but does not

[topaz belfry]

Gotta add more logs to the test version for things like this

But it seems to find the correct TAA shader

Not sure why it's breaking

Did you disable HDR by any chance?

[pastel frigate]

no

its also pretty strange because am sure the game is using default ue4 taa as all cvars seem to work as intended

[topaz belfry]

try disabling it in luma

[pastel frigate]

my bad
i already had it disabled

dlss still greyed out

[topaz belfry]

will check it out in a bit, I think I own the game

[pastel frigate]

Can you also check out days gone
It hooks and everything but no output
I tried fixing the shaders myself but I realized fixing whole pipelines is way harder than simple shader edits i do with 3dmigoto 😅

[topaz belfry]

days gone is a custom UE4 engine

this mod won't work

gotta do a custom mod for it

also I don't own the game

[prisma fulcrum]

Weird but it worked for me, i have steam version.

[pastel frigate]

Thats odd

[prisma fulcrum]

I see that the game isn't in black and white in your screenshot. Is this a mod or does this happen as you progress through the game? I haven't completed it myself, just launch for test. Perhaps switching from black and white to color uses some variables that interfere with DLAA?

[pastel frigate]

reinstalling the game fixed it for me!

[jaunty sphinx]

Been using the plugin with Redout 2 in dx11 mode, dlaa works fine, dlss I don't think so

at least I go from 132 fps of preset M dlaa to fixed 180fps at 90% scaling from the menu with way worse image quality, very similar to what TAA used to be

(I'd like to use dlss at like 60/70% so I can avoid all drops below 180)

is this the expected behaviour?

[prisma fulcrum]

Yes, Luma adds DLAA, i don't think its possible to add DLSS globally like this. In ue lots of effects based on resolution scaling. Probably devs could tell you more.

[topaz belfry]

This is correct. Any post process effect after TAA would have to be fixed

[hybrid hazel]

Luma DLSS for AC:Origins/Odyssey? any plans? I will pay for that

[topaz belfry]

Long baglog of games and things to do. Feel free to donate, but no promises

[pastel frigate]

Tbh the taa in ac origins and odyssey is honestly pretty good on own

[gloomy whale]

I posted in support but I think it fits more here.

I started to replay Star Wars: Fallen Order. I'm using Luma. I was wondering if it is doing DLAA on this specific game. I noticed there are a few presets for DLSS and the debugger shows it is doing preset K. Does Luma's presets override the one being shown. There are noticeable differences when swapping between K and M/L so I was not sure.

Another question in regards to dithering. I am not familiar with it but is it the random pixels I am seeing over the screen sparkling. There is a beta fix in Luma for it but I was not sure what it actually does. However, when I do enable it and restart the option is unchecked each time.

I assume Fallen Order is still a WIP. I seem to keep crashing with Luma running. Without the addon enabled I do not seem to crash with this error.

I noticed the error seems to be the same as when I recently used Luma for Spyro Reignited Trilogy. I ended up having to remove luma for the rest of my playthrough sadly 🙁

[topaz belfry]

the dithering fix likely does nothing for fallen order, I only tested it in one game.

crash is probably related to HDR

disable HDR and it should be good

use renodx: unreal engine instead for now

[gloomy whale]

Ah ok. So I can still use reno while benefiting from Luma DLAA as long as HDR is off? The HDR from in-game and Luma have to be off or something else.

[topaz belfry]

Luma has to be off

not sure if reno requires HDR off for jedi

[gloomy whale]

I'll have to check in a sec. To see if it does or not.

Seems it has to be off but the Renodx UE has no effect with any sliders other than UE. The shaders on it aren't working either. I'll just have to use native HDR or test RTX HDR 🤮

[pseudo harbor]

Use ingame HDR and DisplayCommander for borderless. Luma DLSS can be used, I found only preset M was worth using but it comes with a large performance penalty for not a lot of gain

FSR 3 was pretty good also but has disocclusion artifacts. The other DLSS presets blurred the game more than native or tonemapped details

[gloomy whale]

My presets change but the debugger still shows K for some reason. That is sorta why I asked since I was not too sure.

I am not sure if it is really changing because I am on a 30 series and K vs M has no FPS change.

Maybe I have to keep the original luma DLSS version installed. I updated it with the latest 310.6.0

[topaz belfry]

I will revisit the UE mod again in some time seems like there are some issues. there is no way that the terrible UE TAA is less blurry than DLSS preset F

[gloomy whale]

Just saw the tool tip for the unchecked "Enable Luma HDR" it says "Require rester to apply." Is that intentional of the right word or was it meant to be restart 👀

[topaz belfry]

typo

I should force that to off and fix that typo

[gloomy whale]

I thought so.

Theres the performance hit I was looking for. Seems I manually had to do M through the NVPI. 120 down to 62 is a nope for me. I'll stick to K.

[pseudo harbor]

I think it might have been preset K that blurred the whole screen. Preset F looked good but tonemapped HDR details

or maybe it was the other way around idk

[gloomy whale]

I'll stick with K / native hdr for now. I think the game needs BFF. I never really know when a game needs it or not.

[topaz belfry]

the luma override wasn't working?

[pseudo harbor]

it does https://github.com/KoKlusz/HDR-Gaming-Database/discussions/76

[gloomy whale]

Not for me at least with the debugger. When I change it with luma I see minor AA changes but my FPS remains the same.

[gloomy whale]

I have never quite understood how these picture work. I'm pretty dumb when it comes to the technical understanding of HDR.

[topaz belfry]

you probably find a dark place that should have near 0 black floor and if it doesn't then you know it's a problem

or something like that

[gloomy whale]

Interesting, I usually just toss it on stuff if it has a gross grey filter. It isn't necessary but it makes games look nice for me.

[rigid glacier]

How do I change DLSS to quality or performance on Luma?

[topaz belfry]

Can't, only DLAA

[rigid glacier]

I lose more than 30 fps in Borderlands 3, when using DLAA, is that normal?

[prisma fulcrum]

Depends on your hardware and chosen preset, try cnn presets, they cost less performance.

[plain tulip]

depends on what fps you're starting with
60 fps -> 30 fps is very different from 300 fps -> 270 fps

[rigid glacier]

like around 120 to 85

rtx 4080

[plain tulip]

that seems about right depending on which preset you're using

[rigid glacier]

I was using M

[plain tulip]

lol

try K or something

You really aren't supposed to be using M or L with DLAA

[rigid glacier]

Will try K then

thank you

[plain tulip]

np

[topaz belfry]

What preset?

Yeah with M you can expect that kind of performance hit

Specially at high resolutions

M scales poorly with input resolution compared to the others

[prisma fulcrum]

Idk if its unpopular opinion but 99% of the time i prefer preset C with output scale more than 100% or F for DLAA on 4k screen. Only using M in BF2042 but transformers seems only presets there that remove sharp, its usually opposite.

[rigid glacier]

did not know that

I changed to K and got a huge difference in fps

more than 20 fps back

now it seems right

[rigid glacier]

resolution is 4k

[topaz belfry]

I usually use E even for DLAA but they have removed those presets from latest dlls

I use E with RCAS or some other sharpness

[rigid glacier]

Only problem now, is that I can't get 100% gpu usage in Borderlands 3, when using dx11, only when I use dx12, which Luma doesn't support

[topaz belfry]

we will eventually add support

[prisma fulcrum]

Borderlands 3 kinda better in dx11 still, yeah you have less cpu performance but it isn't stutter as badly as in dx12.

[rigid glacier]

Yes, it stutters a lot in dx12, I guess I will stick with dx11

[prisma fulcrum]

Hmm, ECHO game is listed as supported but i can't get it to work. The menu works but none of the upscaling works. I have gog version. Here is a log.

For some reason it works only on new save file.

[topaz belfry]

no taa detected

not much I can do, I don't own the game

I will add more diagnostic options on the test build to maybe help me with this
UE4 TAA Shader detection for shader 0X6B10DAA4 failed with confidence: 0.00%
very odd stuff here

how was it a candidate for TAA with 0%

[prisma fulcrum]

Seems it same there, but it now works on new save file. And if i go back to old save file it won't still.

[prisma fulcrum]

I figured out what was going on: after the first level, DLAA stopped working. That's why my old save files weren't working. Also there are issues even in first level, with AutoExposure On light sources are strobing, with AutoExposure Off anti aliasing became much worse. I think i should change description of ECHO in mods list then.

[topaz belfry]

please do

sad that it doesn't work

[prisma fulcrum]

Yeah, this game is beautiful, it would benefit from dlaa.

[red heath]

Could somebody test the HDR in a few games again?

i can't reproduce the crashes anymore

might be fixed

@obsidian gale

[obsidian gale]

i haven't faced crashes on luma

so idk

i played project wingman dlc recently no crashes whatsoever

@rapid saffron maybe ?

[red heath]

but originally it crashed?

[obsidian gale]

nope

[rapid saffron]

If I get time Fallen Order was very easy before to crash.

[topaz belfry]

I can test. It crashed pretty consistently on Scarlet Nexus

[fathom frost]

Stray still shows progressive corruption until it crashes with device lost.

[rapid saffron]

Oh, I actually have that still installed even. (Scarlet Nexus)

[red heath]

visual corruption?

how long does it take?

(only with HDR enabled?)

[fathom frost]

Seems to only happen with HDR enabled

Pretty quickly, usually it's enough to pan the camera around for the screen to flash black and afterwards something new is broken

e.g. SSR flickering, broken textures etc

crash is more likely to occur on scene change like going back to the main menu

[red heath]

any idea if the debug layer spits out any warnings?

[red heath]

doesn#t seem like anything

ah nevermind

preview is not all

[fathom frost]

example of the corruption i guess the light probe got corrupted or the wrong texture bound

[topaz belfry]

doens't work

and still gets hung with device lost

[inner mantle]

@topaz belfry is that the scarlet game? bamco game?

it should be the same pipeline as arise

prolly legacy/mobile tm

and has unsafe functions everywhere

[topaz belfry]

it is

[inner mantle]

I watched the anime

I heard the game is better

but its the worst 25 episodes of my life

I finished it out of cope

it was just bad

[topaz belfry]

new version looks good, time to see if it crashes @red heath

[inner mantle]

can you see if it uses the legacy tm

[topaz belfry]

the game is kind of mid ngl

[inner mantle]

even though its not as high contrast as filmic

[inner mantle]

people gassed it up

[topaz belfry]

Tales of Arise is better but also mid

[mint shell]

I remember playing this, the aliasing is quite bad

[inner mantle]

tales of arise I enjoyed

I got over 100h

only thing stopping me from plat is fishing

did all the super bosses

and the final superboss side quest

I enjoyed arise

its not the best game ever, but its the good type of mid that makes you want to keep playing imo

the dlc was kinda meh, but its worth playing if you beat the og game

[red heath]

i will re-enalbe the HDR flag by default if it works

and make an announcment

we shall gather a few HDR+DLSS vs SDR+TAA comparisons

[topaz belfry]

still lost device with previous fix

hopefully this last one solves it

[red heath]

ah then probably not

not my lucky day

@inner mantle time for your first luma task

carry over all the game specific UE generic renodx mod shaders that remove a "saturate()" at the end

🙂

[inner mantle]

I already sent some

for arise

[red heath]

copy and paste all?

[inner mantle]

I dont know any saturates or max(0's -- but I know a bunch like SMT5 where its another whole grading curve

and you want to create a new sdr color, and then upgradetonemap

or ideally tonemap in that shader

[inner mantle]

I'll look through the list, but idk which ones are quick fixs and which are more complex

I think most things in the src/games/unrealengine/games/ folder is simple

@cursive reef prolly knows more than me

most of the fixs in unrealengine/games/ are
-> remove max(0 or saturate
-> maybe make a safe function safe

but I am looking forward to this working in DX12/DXC -- so I can ditch ue extended and just use this

with framegen and all that

[gleaming wing]

CTD w/ Stray on Steam

[red heath]

use this, it will print debug information in the output

dx log

[topaz belfry]

no visible error in the logs for me

cant find any dx log

[topaz belfry]

debug layer seems to not make it crash, the image just break progressively more.

no relevant errors in the log

[gleaming wing]

works fine w/ Styx 2 on EGS

[red heath]

can u check if the gpu vram goes too high

and crashes due to out of memroy

[topaz belfry]

I'll check tomorrow, but in my case the game never crashes just device gets lost and the main thread freezes.

[red heath]

then it's probably luma accessing some stale resource

[topaz belfry]

In the logs from @gleaming wing there was a fail to create swapchain

I thought it was going to be compilation issues on patched shaders, but no errors there.

[gleaming wing]

works fine when disable Luma HDR and using RenoDX

[red heath]

I could take a key for Stray if somebody wants to send it over.

[cursive reef]

most of them should be simple saturates like Marat said, I think only rain code and scarlet nexus have more complex shaders that need fixing

for dx11. if you want to add dx12 down the road, there are a ton more games that have some kind of post process that clamp

[red heath]

we are adding 9 to 12

[cursive reef]

nice, I'm planning on playing a bunch of games once the crashing is fixed

dumb question, does this code run for the lutbuilder generated luts https://github.com/Filoppi/Luma-Framework/blob/main/Shaders/Unreal Engine/Luma_UpgradeTonemapLUT.hlsl

[red heath]

yeah that makes assumptions on how UE build luts

and fixes them in "post"

it's not the definitive version though

what I willd do is re-write the code from every single version of UE

detect the engine version the game uses

and compile a version of the lut builder that matches what the game had, from our code

so we can do antyhing we want

[inner mantle]

why are you guys dumping all the game shaders in the shaders/unreal engine/ folder

vs.

/shaders/unreal engine/games/talesofarise/

also I never understood seperating the game shaders and cpp files, making users dig through directories

but its not my project, I just look around for code to yoink

@topaz belfry maybe you can englighten me

[topaz belfry]

I actually want this feature also want to be able to load shaders from sub folders so that not all shaders have to be prefixed with game name and live on the unreal engine top level folder.

[inner mantle]

unironically renodx has a good folder structure

everything related to the game lives in its own folder

/src/games/MyFavoriteFutaGirlfriend

from addon.cpp to lutbuilder.hlsl

and then we have /src/shaders/ for generic stuff like colorspace conversions, etc

[red heath]

the Unity mod does

      std::filesystem::path file_path = System::GetModulePath(hModule);
      std::string file_name = file_path.stem().string();
      // Retrieve the dll name and use it as the addon name, so we can re-use this template mod for all games by simply renaming the executable (as long as the mod just involves replacing shaders).
      bool use_custom_game_name = false;
      if (file_name.starts_with(std::string(Globals::MOD_NAME) + "-"))
      {
         file_name.erase(0, std::string(Globals::MOD_NAME).length() + 1);
         if (file_name.starts_with('_'))
            file_name.erase(0, 1);
         if (file_name != "Generic" && file_name != "Generic Mod" && file_name != "GenericMod")
            use_custom_game_name = true;
      }

      const char* project_name = PROJECT_NAME;
      const char* cleared_project_name = (project_name[0] == '_') ? (project_name + 1) : project_name; // Remove the potential "_" at the beginning

      const char* game_name = use_custom_game_name ? file_name.c_str() : cleared_project_name; // Can include spaces!
      std::string mod_description = "Generic Luma mod";
      if (use_custom_game_name)
      {
         sub_game_shaders_appendix = file_name;
         mod_description += " for " + file_name;
      }
      else
      {
         sub_game_shaders_appendix = System::GetProcessExecutableName();
      }

generic mod will dump in the game exe name subfolder.

sub_game_shaders_appendix = System::GetProcessExecutableName();

can just add this to UE mod

[topaz belfry]

Should do that yeah

[red heath]

we do not dump shaders for the UE mod.

it's all live patched.

[red heath]

it's done like that in reno because shaders are precompiled in the c++ binary

we ship shaders as hlsl

[inner mantle]

I know

[inner mantle]

I mean I'm no project setup pro; but cant you still do that with 1 folder

unless your pipeline is different

on how it builds

just feels comfy to live in 1 folder idk

wait I'm stupid

if you ship hlsl, you need to ship dice and all color hlsl

so yea makes sense

sorry

[red heath]

i don't like it personally

in every application i used, c++ and shaders are in different folders

[inner mantle]

thats good enough of a reason for me

[red heath]

and it works great

[inner mantle]

its your project, you set it up how you like it

[inner mantle]

makes sense

real games are big projects

and shaders are a "small" part of it

vs. a game mod that is just "1 folder"

[red heath]

i'd need overly complicated scripts to package files with the addon too

[red heath]

luma mods can be huge

Prey replaces 200 shaders

[inner mantle]

I was talking about

[red heath]

some even 1000 or 2000

[inner mantle]

like a real full unreal project

being 500000 files

and 50 terabytes

not saying luma mods are smol

was just saying it makes sense why "real projects" that you worked on seperated hlsl

[topaz belfry]

I think I am getting close to understanding the issue with FFXV somehow the rtvs are not being set properly? it finds the correct resource in the pool but the OMSetRenderTarget seems to be failing silently sometimes for some reason

[red heath]

use the debug laeyr

could be resources get unbound

because they were bound as SRV somewhere else

[topaz belfry]

will try that next, been adding a million logs to test and been using local llm to parse trough them

[red heath]

should have been first thing

should often check it when modding

[topaz belfry]

always a pain to modify reshade to enable it but yeah

should keep it on a git stash somewhere

[topaz belfry]

huh nothing in the debug layer

Just realized I'm doing this in the unreal engine thread

[red heath]

u sure?

[topaz belfry]

yeah I used the dxgi you shared above for testing UE HDR

[topaz belfry]

I figured it out, game had a DSV bound that was of a difference size causing it to fail.

I will debug the other issues tomorrow

[cursive reef]

I see. already looks really great.

out of curiosity I ported it to reno (or well, a clanker did lol) and added it in a bunch of koei tecmo games. they have baked color grading + tonemapping luts, and it looks way better than before. could I add this to my mods?

with credit ofc

32:9 vs 16:9 vs 3:4. The wider the viewport, the weaker the DoF.
It doesn't matter how DoF would scale in a real camera if its film changed aspect, all that matter is the aspect ratio artists authored the DoF params with, any extra side should preserve the same blur, with the

post some screenshots

are they DX12?

did they have multiple grading passes or just one bundled with more LUTs?

[cursive reef]

some are dx11, some dx12

[cursive reef]

just one grading shader at a time, and they sample an hdr lut, 2 dramatic hdr luts with masks, and an sdr lut

SDR | Luma UE Upgrade Tonemap

looked like this previously with reno's upgradetonemap and some less than stellar solutions to get a bit more highlight sat back

SDR | Luma UE Upgrade Tonemap

[red heath]

If u have the specific shaders, u could do even better though!

[cursive reef]

how would I do that? there's no lutbuilder here, and I only added this method to handle the baked g_tHdrLut for now

[red heath]

Can you explain more? Not sure I understand yet.

[cursive reef]

Koei games don't use UE. They usually load color grading and tonemap LUTs from disk, so I was using reno's upgrade tonemap before. I tried out your UE code and it's way better

[cursive reef]

I thought you meant that there's even something better I should be using instead ^^

[red heath]

yes i mean

my code is made for unreal

so it decodes LUTs with log encoding

the way UE makes them

also if u have access to native source code of the shaders

for game specific patches

it makes little sense to use my generic upgrade code

IMO 😛

[cursive reef]

Ya, I changed that to their arri encode and decode

Would probably look really borked otherwise lol

[cursive reef]

I'm not exactly sure what this means

UE is kinda open source, but not the Katana engine

[red heath]

i mean, u have the whole shader source decompiled

so u can write code specifci to the game

my mod was generic

[cursive reef]

Ahh

Yea makes sense

Sorry lol

[red heath]

just a suggestion

[inner mantle]

yea those games dont give you lutbuilders when the game is in sdr

and only the new ones give you a lutbuilder when the game is in native hdr

I mean their tonemappers are some shitty filmic tm at home, just like ue filmic

so it might look fine

[inner mantle]

@cursive reef the red skin on his foot is a bit rough though

but yea sadly in these games, the luts are black-boxs

the best we can do is like max channel upgradetonemap or some sort of invert setup where we try to retain as much info as possible

[cursive reef]

maybe a bit, yea. I used Pumbo's defaults, so 0.66 hue correction and 0.33 chrominance iirc so you could tweak that

[red heath]

i don't know if there's a bug now, maybe some xxy xyz accident

cuz i noticed skin turning red too

everything else looks ok

maybe ask AI to find bugs

[cursive reef]

Just in my screenshots? Or also in your mod

If it's the former I probably messed up

[cursive reef]

Will do, thx

[red heath]

In my mod.

[topaz belfry]

is hue correction / chrominance in LMS?

[cursive reef]

I used oklab for my RestoreHueAndChrominance reno substitute for now, since I'd assumed that's what Luma used. But it uses JzAzBz I think, so that changes things

I briefly tried macleod boynton (CorrectHueAndPurityMBBT709WithBT2020()) but saw some artifacts for some reason

[topaz belfry]

maybe negative numbers from fp errors?

[cursive reef]

maybe, not sure. they just show up with bright highly saturated colors. if you use hue correction with oklab or something and put that to 100% you get similar artifacts, but with macleod they show up even with low hue correction strength

must be doing something wrong, you didn't have such issues in granblue right

[topaz belfry]

no I didn't

[limpid loom]

Symbiote spyro

[inner mantle]

@cursive reef any benefit to jazzbazz vs. oklab

I use HueAndChromaOKLAB()

because oklab is basically ole reliable

[cursive reef]

Only tested it a bit, and it looked similar to ictcp. Both are probably better or have fewer quirks than oklab

[red heath]

Unsure.

They are all OK.

Only one is lab
