✅RenoDX: Baldur's Gate 3

[viscid folio]

not related to tonemapping

[hot sedge]

Is there an ETA on update?

[viscid folio]

no

maybe this month

[wispy eagle]

Are you on amd or nvidia?

Think it might be a amd issue

Installing older drivers might work but i cant be asked doing that for one game

[hot sedge]

On nvidia

[fluid valve]

I also use AMD and it doesn't work for me.

[viscid folio]

Someone was saying it didn’t work for them but it just turned out that the shader didn’t rerun unless they went into the settings menu and moved any of the hdr calibration sliders

Idk why it’s that way on some systems

[fluid valve]

lol this could be because of mods

Yeah this is what my game looks like with Renodx now. If I turn the add-on off it goes back to normal.

But, now that I turned it off, I can tell it was working the whole time.

I just need to get it working again.

Ok, shader is working again. Gamma 2.2 is noticeable, but sliders do not affect anything.

Good enough

[marsh crescent]

Had no Reno troubles with AMD. Didn't really get into the game yet, though.

[warm marten]

I get this sometimes too. I do have some mods but none of which are graphical.

[viscid folio]

updated

[rough shell]

On Linux, AMD, using reshade 6.7.1 and the latest proton-ge. Unfortunately I can't get the addon to work-- The only option that works is the UI brightness, and changing window mode or in-game HDR sliders doesn't make RenoDX tonemapping apply. Everything else just looks the same as vanilla

[wispy eagle]

Yeah same but on windows

[cedar owl]

Should I use dx11 or vulkan ?

[viscid folio]

Dx11

I’ll switch to vulkan later

[cedar owl]

Weird I used vulkan abd that worked

And when you mean dx11 you mean the dx11 exe or choose dx11 with the normal exe

[viscid folio]

actually doesn't matter which exe you use cause it really just drops the dll file in the folder

[cedar owl]

Okay wlll uninstall
And choose dx11 this time

But it’s weird it worked with vulkan

[torn hollow]

The addon might load

but its not going to do anything

since Vulkan has completely differernt shaders compared to DX11

[worldly ginkgo]

Musa do you remember what nits in this game emulated the SDR look like how Koklusz posts comparisons? Thanks

If i wanted to be anal about what level to set the game brightness

[worldly ginkgo]

I get this problem when I set to 4000 or higher

[worldly ginkgo]

@viscid folio did the new tonemapper in Jan. 2026 change it from per channel to something else? Or vice versa? Trying to see if my eyes understand what's happening

Also is the ACES 2.0 danielle curve considered more accurate for translating SDR variables to HDR brightness?

[viscid folio]

Forge took over the mod so its all his stuff

[worldly ginkgo]

Thanks!

@torn hollow what did the new tonemapper change regarding creative intent? Did it change per channel color whatever? Trynig to understand what the new tonemapper does: Translates to ACES 2.0? is that better for this game than PsychoV?

[torn hollow]

Removed ACES 2.0 beta that Larian uses entirely

Replaced with PsychoV

removed their shadow saturation and other custom grading

replicated the original look using a split contrast function Musa already had

The game now matches SDR in regards to hues (no more pink flames, sand ect)

Theres no disgusting shadow saturation that smears everything and makes it look cheap

[solar walrus]

sdr variables to hdr brightness?

[worldly ginkgo]

Yessssssss

[worldly ginkgo]

are there places where it doesn't match SDR other than brightness? Thanks!!

[worldly ginkgo]

color I guess? I'm new at this so sorry if i'm mispeaking

[worldly ginkgo]

i guess but how does that compare to SDR thanks

[torn hollow]

I am doing graphics stuff as well

This addon isnt just colour

and tonemapping

[torn hollow]

SDR has the same shadow saturation and smearing

The only difference is that it doesnt grief with pink flames and sand

[solar walrus]

so sdr to hdr would actually be inverse tonemapping.

If I am understanding you correctly

[worldly ginkgo]

i thought the point of tonemappers was to take SDR colors and show them at a correct brightness and hue or if the creator modded it, creative intent

[worldly ginkgo]

Thre's so much more detail dude,

this feels like a next-gen update lol

i feel like i have to repay the whole game!

or at least my top save files

[torn hollow]

Grymforge and other underdark areas lacked shadowing entirely

[worldly ginkgo]

ah so it's the shadows

wow

I will say this: my flames have almost a greenish tint now

[worldly ginkgo]

so these shadows existed in SDR? Sorry if all of this is stupid questions thanks

[torn hollow]

They dont exist at all

in the game

I started REing the .exe

I want to fix LODs

and their virtualtextures causing loading/unloading

maybe increase shadow res as well

I'll return since I still need to finish the addon

colour and grading are pretty much done

[worldly ginkgo]

Wow

[torn hollow]

its just rendering stuff

[worldly ginkgo]

So there's still more? Shadows?

Dang this is where they say that you re-write engines lol

You personally

[solar walrus]

tonemapping is basically just a form of compression.

So let's say a game untonemapped outputs 100,000 nits but your display can only hit 1,000 nits in hdr. To be able to display the game in a way that looks pleasing you would use tonemapping to compress that 100,000 nits to be able to fit into your 1,000 nit display.

[worldly ginkgo]

yeah but psychoV tries to change the color based on the light intensity

and other tonemappers try to desaturate the tones to match film

[worldly ginkgo]

this is like a different game (in a good way)

i want to play it first person now practically

[worldly ginkgo]

Scared to ask, but can you put in a tonemapper switcher so we can compare the new and old? Would love to see the diferences thanks!

[solar walrus]

there's dozens of different philosophies on what tonemapping should and shouldn't do to achieve a subjectively appealing look. You can't just compress the range and have it look good most of the time, eventhough the core of tonemapping is compression.

[worldly ginkgo]

Understood, it starts with compression got it

[torn hollow]

Theres already an off mode

it disables all the graphics additions

and approximates vanilla toneampper + look

(We cant do real time toggle becasue of the LUTbuilder, its not per frame)

You'd need to leave to main menu and enter back in for it to rebuild

[worldly ginkgo]

Ok so to see old tonemapper turn it off and then go to main menu and come back

Is there a way to get that above 1000 nits? Thanks!

[worldly ginkgo]

@torn hollow Hey man there is major clipping or corruption of the brightest values in the Mystra and Vlaakith scenes, I can send you a save file if you don't have one, you can tell it's just the brightest values in the scene that are off

[worldly ginkgo]

@torn hollow if I turn off the tonempaper setting / use Vanilla, does that turn off your shadows? thanks

[torn hollow]

Pics?

[torn hollow]

The only way to get "vanilla" is to set to the off preset. Which disables all the graphical additions

[worldly ginkgo]

Ok i'll get them today

[worldly ginkgo]

Yo I hope this isn't rude but is it a lot of work to re-add what Musa did as an optino b/c i'd love to have it until those other scenes i mentioned are working right, no worries if not thank you man

[hot sedge]

Will this be compatible with shadows mod from nexus?

[torn hollow]

I built with it in mind

Shadows of the gate doesn't change the shaders

It just adds shadow casting flags to materials

And light sources

There's a way to do it .exe side which I've been reverse engineering. Gosh mentioned there's a better way to do it so I am taking a look

[hot sedge]

ok i will delay playing this game for a few months more

[worldly ginkgo]

this is awesome, any other mods i should know about? i have plenty but hadn't heard of this one..

[hot sedge]

Another one strictly technical mod i installed - vivid landscapes

[worldly ginkgo]

yeah i have that one! Thank you

[worldly ginkgo]

@torn hollow , here are the screenshots I mentioned where everything is clipping or something :

[worldly ginkgo]

@torn hollow these screenshots are from the January build on Nexus, is the Vulkan one better? The Vulkan build has rough skin textures for me but the colors seem more matched to the SDR intent to me, any reason for that? Thanks!

[viscid folio]

vulkan build rewrote everything

it's entirely different

[rough shell]

Ooh a vulkan rewrite? Might have to check it out on Linux and see if it works for me now.
