Unreal Engine

[placid siren]

Universal mod for UE 4.x and UE 5.x

Works by upgrading the SDR path to HDR10 swapchain and computing a dynamic SDR=>HDR scaling and applying with RenoDRT (not ACES specific).

Links:

• Repo Build

• Use pinned Reshade from #📝welcome
  Instructions:

• Install Reshade 6.5.1+ (if using Xbox Games, pick the gamelaunchhelper.exe file)

• Install renodx-unrealengine.addon64 file next to game exe (usually called xxxxx-Shipping-Win64.exe)

• Launch game

You should not apply any .ini modifications to enable HDR.

If you are having issues a shader is likely needed. You can help by

• Check https://github.com/clshortfuse/renodx/wiki/Mods for game specific details
• Switching Settings Mode to Advanced
• Turn On Dump LUT Shaders
• Upload files in renodx folder (will be called lutbuilder_0x12345678.cso)

The actual work that needs to be done to the lutbuilders is described in guides/Unreal Engine Modding

[bleak nest]

We should use this for dumping LUTs as well, I think?

@swift plover was right to keep #🧪lab for more intricate testing/collaboration and not the dumb grunt work stuff that's usually shaders at this point.

[placid siren]

yeah, here is fine. keeps things organized.

[polar crest]

@placid siren I added this since people kept asking me about the sliders change in UE5 titles

[placid siren]

@dusty girder the bgr8 upgrade in stellar blade demo is what tanks performance, stocklike without it

like 40fps => 15fps

[regal kayak]

@dusty girder I've got a lutbuilder that's seemingly missing a ap1 -> bt709 conversion. Is this a thing that happens sometimes?

[dusty girder]

thats a weird one

idk if I've seen that before

sdr?

some old lutbuilders might be weird

[regal kayak]

lutbuilder in question

[dusty girder]

give me 3 minutes

[regal kayak]

it's ue4

came from Outriders

also dumped another lutbuilder, it's possible this one doesn't matter

the other was pretty typical

oh I might be dumb, there's a chance that one dumped with hdr enabled

[dusty girder]

oh this looks like one of those

AA lutbuilders

[placid siren]

latest unreal has _new tag

[dusty girder]

or native hdr lutbuilders

thats probably junk unless the game actually draws that

[regal kayak]

yeah I think I'm just dumb and forgot I had it set to dump when native hdr was on

[dusty girder]

THANK YOU

[regal kayak]

seems to work with just this lutbuilder added

I've got a good stack of commits piled up and keep putting off making a PR

[bleak nest]

I was wondering that day why not just dump newer ones in a separate folder and older ones in another, etc.

But _new tag also works well.

[dusty girder]

no

people already have a hard time

finding one folder

[bleak nest]

It'd have gone in that same folder, just titled old.

But _new works just as fine.

So, not really an issue.

[bleak nest]

There is just one problem with this method, though.

Not all the modders are in the channel that can simply see the msg and compile something for you.

For instance, Ritsu compiled MGS stuff for me instantly, and he's not in the thread. Same with countless others.

#🆘helpdesk it is, I guess.

[regal kayak]

Since it’s a never ending project, we could just have “unreal work queue” channel or something where unimplemented lutbuilders get posted. We delete the post when done.

[dusty girder]

yea I asked for that a few times

where people can post dumped lutbuilders

and we can mark them as added

[regal kayak]

It’s too easy for lutbuilders to get lost in messages otherwise

[bleak nest]

A request channel where someone dumps it, and whenever any modder takes charge of that, they take the convo to appropriate channel i.e. Unreal Engine thread, and tag the poster and continues convo there.

And then delete/mark the original posting.

[dusty girder]

I've lost a few

until people repinged me

sometimes I try to get to them asap, but I might be doing something

and then when I go back later; I cant find it

[bleak nest]

Can someone compile these, pls. new new shaders when I tried to play Six Days in Fallujah with it.

[dusty girder]

I'll do it tomorrow

[dusty girder]

@bleak nest lmk if it works

also is the game UE4?

[bleak nest]

Yeah, UE4.

lemme try.

[dusty girder]

figured, ue4 games with sm6 shaders have all those branches

you'll probably need to upgrade bgr8_typeless and/or rgb10a2 unorm

[bleak nest]

Sliders are working now, but game is 202.9121 capped.

Do I need to remove all upgrades, too?

I'll try copy destinations.

Copy upgrade paths, and menu goes higher.

Works now.

How do I determine what upgrades it needs? Check them one by one?

In-game is capped, not sure why.

Menu and cutscenes are fine, in-game gets rekt.

[dusty girder]

well unreal engine only really needs 3

bgra8 typeless, bgra8 unorm, rgb10a2

unorm isnt common

[bleak nest]

Upgarde Copy Destinations upgrades all at once?

[dusty girder]

upgrades

[dusty girder]

copy destinations only if upgrades dont work

try upgrading all 3 to output size, and if it doesnt work

enable "upgrade copy destinations"

[bleak nest]

that rgb10a2 is always unorm, right?

Not typeless?

[dusty girder]

yes

rgb10a2 unorm

[bleak nest]

That worked.

In-game, as well as cutscene.

[dusty girder]

so lutbuilders good?

off to github

[bleak nest]

Yes

That sun has a darkness around it, what causes that?

[dusty girder]

idk

might be the suns texture

@placid siren https://github.com/clshortfuse/renodx/pull/382

[bleak nest]

A certain upgrade or two wouldn't cause that, yea?

[dusty girder]

ohh that ring

it might, but honestly idk

maybe its always like that

and the sdr blowout just like hides it

if upgrade copy destinations fixed it

you can start disabling upgrades

and seeing which ones you need

[placid siren]

input needs to be clipped to 100.f probably

[dusty girder]

I dont like adding per-game fixs to unrealengine's lutbuilders; because a fix for one game might grief 40 other games

[bleak nest]

if 100.f fixes that, can just throw it and call it a dedicated mod and move on.

Throw it as a separate repo.

And not grief other games.

[dusty girder]

yep

thats what I do

[bleak nest]

Yeah, doing that now.

[dusty girder]

I always try to make sure lut inputs and sdr grading is done within the sdr range

the results are usually better

[bleak nest]

RGB10A2 UNORM alone doesn't work, so throwing in BGRA8 TYPELESS to it now.

Upgrade_R10G10B10A2_UNORM=1```

Should this be flickering like a maniac?

Game only ships with a single DLSS file.

And it's that version, old.

[bleak nest]

Those two upgrades alone worked. Let's see the sun in-game now.

And the sun is like that.

Seems only in-game, too. The cutscene sun was as bright but no BS like that.

Maybe distance to it or something? not sure.

But if 100.f can fix that, I can test it.

HDR looks goooooooooood in the game.

The smoke is going very black as well.

It's not like that otherwise.

[bleak nest]

Or that I remember, at least. Will check without it later.

But it's 'good 'nuff' already.

[sturdy lagoon]

Looks cool

[sonic copper]

Can someone help me compile these? Its' for Mafia: The Old Country. The game starts with intro videos playing but the main menu is just a black screen with audio

[bleak nest]

Did you do upgrades?

[sonic copper]

Yeah I did that

[bleak nest]

And you're using latest RenoDX UE snapshot from GitHub?

[sonic copper]

yep

[bleak nest]

As well as latest RenoDX ReShade nightly?

[sonic copper]

yeah I used that and the snapshot

[bleak nest]

Someone else also had that issue few days ago, not sure what's up.

I played the game and it was fine.

[sonic copper]

yeah but I think it just had an update right?

So it's missing shaders if I'm not mistaken?

[bleak nest]

Well, neither of those mention _new in them, so unlikely.

[sonic copper]

I understand. Probably a dumb question but does _new mean those are new shaders?

[bleak nest]

yee

[placid siren]

dlss maybe?

[sonic copper]

Do I need to add the dlss fix?

[placid siren]

try without dlss to narrow down what's causing the issue

[sonic copper]

wow

it worked

anything but dlss works

[placid siren]

is there a scale, sometimes 99% works

[sonic copper]

what do you mean by scale

I have a sharpness scale

I can use unreal tsr, fsr, and xess

[sonic copper]

are you talking about a scale in relation to the upscaler quality?

[placid siren]

i think so, i know people move some slider to 99% because 100% breaks

[sonic copper]

yeah thats not in this game. There is just a sharpness scale

[regal kayak]

@dusty girder did we ever figure out a good way to upgrade CAS shaders?

[placid siren]

could try dlssfix, but i know other people got it all working fine. maybe they updated something

[sonic copper]

so that could allow me to use dlss then?

[placid siren]

and avoid dlssfg flicker

[sonic copper]

I tried it but it didn't work. I don't know if I entered it right

in the reshade.ini that is

[regal kayak]

alright I added borderlands 3 to the mod list, but the CAS sharpening option in game sets itself to on every time you boot it and it needs to be off

[swift plover]

Replace the cas

Ask Lilium for her RCAS

[regal kayak]

I mean, that would be cool to have permission to use in the generic unreal addon

idk if shortfuse wants to make it a part of it though

hm, game has native hdr, maybe it has a different version of the shader for that and I could copy paste

[swift plover]

Some of the games in the unreal addon have their custom shaders added

You can just tune rcas to match their cas close enough

[regal kayak]

yeah it's what I'll do for this if I can find an acceptable fix for this, but regular CAS kinda seems very SDR focused

[swift plover]

Lilium also has cas code

I haven’t looked at the shader

[regal kayak]

they do have a different permutation for HDR

all the same inputs, I should be able to copy paste and we'll be good. This might also be a good solution for the other games that are broken with CAS.

did not work

RIP

oh weird this is PQ encoding

pq decode every sample, pq encode at end (not bt709/bt2020 conversions btw)

that explains why the native HDR is super saturated, if I remember what not converting it looks like at least...

wait I might be dumb

[swift plover]

So they’re going back to linear with every sample and then back to pq at the end

The lutbuilder would have outputted in pq in hdr

[regal kayak]

I think I got it backwards, I think they're PQ encoding every sample and then decoding at end

[swift plover]

Sharpening should be run in linear

It might just be like far cry 6

Where you literally just have to remove a saturate

And the sharpening works fine

Far cry 6 had clamped sharpening in hdr

[regal kayak]

I removed the saturate and it unclamped but went neon

[regal kayak]

nvm I was right the first time I think. I mix up the funny numbers too much.

@placid siren would it be okay if I added a shader to the addon just to bypass it? It's CAS which clamps and I don't know enough to get it working

main reason I even care to add it is because it's in borderlands 3 and every time you start the game it forces the shader back on

or maybe we could integrate RCAS like musa suggested

[placid siren]

Look at https://github.com/clshortfuse/renodx/blob/5734a7a4029a6a99368302a90bda120c2987a5cb/src/games/starfield/common.hlsl#L7

CAS doesn't/shouldn't clamp

It's just a plus shaped sample

[regal kayak]

there are a few unreal games where it does

[placid siren]

Center, and the above left right below

C in this case is center

[regal kayak]

the supermassive games also do

lemme send the shader real quick

here's the SDR permutation

HDR permutation

[placid siren]

Just take the load calls

And stitch the abcde

See https://github.com/clshortfuse/renodx/blob/5734a7a4029a6a99368302a90bda120c2987a5cb/src/games/starfield/cas/cas_0x91461C11.cs_6_6.hlsl#L146

[regal kayak]

alright

[placid siren]

It has two

Like in Starfield

C is the same in both (center)
Then abde are branched

So you see 9 total: center + 4 +4

Which set of 4 is branched somewhere

[regal kayak]

would you want these functions added into common or a separate file in the game folder?

[dusty girder]

merge pls

[regal kayak]

guess I could just put it into the shader itself

[placid siren]

Just can copy the CAS function somewhere, like effects

Starfield used green instead of Y for speed

[regal kayak]

you mean like, shaders/effects or somewhere for unreal specifically? I'm anxious about touching anything outside of the games folder lol

[dusty girder]

btw what did you mean about upgrading cas when you pinged me

the only issue I've ran into with CAS or NIS was having to upgrade UAVs to unclamp (destinations slider in the UE mod)

[regal kayak]

oh, I thought it was an issue you ran into before

guess it was just me with supermassive games and now bl3

[dusty girder]

my hentai games dont really get fancy stuff like cas

fxaa sure

[placid siren]

gave copilot my cas as context,

[regal kayak]

thanks

[placid siren]

with cas function

it's partially wrong since it'smissing the branch

but the game does gamma 2 it seems

[regal kayak]

there being 9 loads is confusing me. I don't really get what it's doing I guess.

[placid siren]

what are the cbuffer values?

[regal kayak]

no clue

[placid siren]

can you check?

[regal kayak]

sure, I'd have to get a renderdoc/pix capture for that right?

[placid siren]

devkit

[regal kayak]

oh

[placid siren]

you have to enable capture cbuffers in devkit settings and restart

[regal kayak]

never realized that was there

[placid siren]

squared is a cheap gamma => linear

[dusty girder]

wow ai got a lot better with fxc

not just COLOR TRANSFORMATIOnm

[placid siren]

well, i'm feeding it context

[dusty girder]

ah

[placid siren]

it's cas, there's 9 points, one is center etc

[dusty girder]

makes sense,

[placid siren]

https://www.youtube.com/watch?v=6QmGJxyADk8

it's actually a perfect reference that probably won't be understood

[dusty girder]

yea sadly idk where its from

[placid siren]

coincidentally, it's a computer that is playing tic tac toe over and over and he's asking the computer to learn from repeated attempts

which is basically how AI works anyway

https://www.youtube.com/watch?v=F7qOV8xonfY

[regal kayak]

lmao, I shouldn't have needed that for it to make sense. I was hung up on the abcde thing

[dusty girder]

I'm a big beleiver in visual learning

[placid siren]

·a·
bcd
·e·

[regal kayak]

I see

I enabled trace cbuffers in devkit but I'm not seeing where they show up

I restarted

[placid siren]

picture of snapshot?

[dusty girder]

btw this is random; but devkit 5_x support when

[placid siren]

click preview

[placid siren]

is this dx12? hmm, why no pixel shaders

[regal kayak]

yes dx12

I can switch to dx11 though

[dusty girder]

you can do -d3d11 yea

[placid siren]

dx12 cbuffers are rough

one contiguous memory block

[dusty girder]

if the shaders are the same

[placid siren]

should be fine to understand what it's going

[regal kayak]

sm 5.0 so probably

[dusty girder]

yea, ue4 keeps the same shaders

dx11 and 12

if 12 is sm5

[placid siren]

actually, there are 9 draws so.. probably not rcas, just cas or vice versa

abc
def
ghi

[regal kayak]

this game came out when regular cas was newish

[placid siren]

there's cas and there's rcas

[regal kayak]

yeah like this predates even fsr1 iirc

I don't think rcas was a thing

[placid siren]

oof, a 1 + 8 + 4 model

https://github.com/GPUOpen-LibrariesAndSDKs/FidelityFX-SDK/blob/54fbaafdc34716811751bea5032700e78f5a0f33/sdk/include/FidelityFX/gpu/cas/ffx_cas.h

  // Summary of inferred offsets relative to base (x,y):
  // r4 = ( x,   y )   // CENTER
  // r0 = ( x+1, y )   // right
  // r6 = ( x-1, y )   // left
  // r8 = ( x,   y-1 ) // up
  // r9 = ( x,   y+1 ) // down
  // r7 = ( x-1, y-1 ) // top-left
  // r5 = ( x+1, y-1 ) // top-right
  // r3 = ( x-1, y+1 ) // bottom-left
  // r2 = ( x+1, y+1 ) // bottom-right
  // Summary: center is in r0; neighbor samples are in r4,r6,r8,r9,r7,r5,r3,r2.
  // The later coefficient math uses these registers to build two 4-sample
  // neighbor groups and compute adaptive weights for the CAS-like filter.
  // r*.y values now represent the chosen luminance proxy of each sample
  // compute the minimum luminance across the neighborhood

[regal kayak]

okay, it's the same shader and I've got a preview. New values constantly though

[placid siren]

so it's not the 5 point cas

might be reused buffer, windows shift s and pray

[regal kayak]

idk how helpful this will be, the values change a lot

[dusty girder]

spekaing of UE

do we have an example of a UE game with custom grain

ideally SM5

[placid siren]

what's the resolutino of the game, surely not 180x430, right?

[regal kayak]

3440x1440, which are values that show up in here every once in a while

like now lol

[placid siren]

yeah, there we go

1/3440 = 0.00029069767441860465

1/1440 = 0.0006944444444444445

because floating point division is rough on gpus

i just feed it the screenshot and it actually understood it

// Example cb0 usage / sample values (from a capture at 3440x1440):
// - The shader uses cb0[1] as a UV scale/offset to convert SV_POSITION
//   into integer texel coordinates. In a 3440x1440 frame you can observe:
//     screen resolution:      width = 3440, height = 1440
//     reciprocal (1/width):   ~0.00029069767
//     reciprocal (1/height):  ~0.00069444446
// - In the decompiled math r1.xyzw is multiplied by cb0[1].xxyy then
//   offset by cb0[1].zzww, i.e. roughly: texUV = pos * (1/width,1/height) + offset
// - Those small reciprocal values (shown above) are what map the large
//   SV_POSITION coordinates (e.g. 3440,1440) into [0..1] UV space before
//   floor() produces integer texel indices. The table cb0[2] holds other
//   coefficient lookup values used later for weight generation.

[regal kayak]

crazy

[placid siren]

you honestly have enough for your own 5 point cas though

  r1.xyzw = min(float4(1, 1, 1, 1), r1.xyzw);
  r11.xyzw = min(float4(1, 1, 1, 1), r11.xyzw);

this will clamp

but i'm making it do the work of figuring out the 9 point cas system used

[regal kayak]

I feel like the better solution would be to ask lilium if we could put RCAS into the mod and then just swap out sharpening shaders as we desire.

but it's also cool if there's an easy way to fix games where this comes up

[placid siren]

i already gave you the rcas code

[regal kayak]

oh...

[placid siren]

it's in starfield

[regal kayak]

oh my bad, I thought that was normal CAS

[placid siren]

i don't remember which is 9 and which is 5

but lilium's is the same as starfield which is 5

i mean, the code is all in the AMD repo, just lots of noise

// Summary of inferred offsets relative to base (x,y):
  // r4 = ( x,   y )   // CENTER
  // r0 = ( x+1, y )   // right
  // r6 = ( x-1, y )   // left
  // r8 = ( x,   y-1 ) // up
  // r9 = ( x,   y+1 ) // down

you'd plug in those 5 points

[regal kayak]

the RCAS implementation we've done in some other games doesn't require computed positions, we just pass it the one set of coordinates iirc

[placid siren]

it definitely needs positions

i don't think you can get proper position without screen resolution

or maybe you do

since it's +1 int

and it's a load operation

[placid siren]

float3 b =
      renodx::color::gamma::DecodeSafe(SamplerFrameBuffer_TEX.SampleLevel(SamplerFrameBuffer_SMP_s, tex_coord + float2(0, -1) * texel_size, 0).rgb);
  float3 d =
  renodx::color::gamma::DecodeSafe(SamplerFrameBuffer_TEX.SampleLevel(SamplerFrameBuffer_SMP_s, tex_coord + float2(-1, 0) * texel_size, 0).rgb);
  float3 e =
      center_color;
  float3 f =
  renodx::color::gamma::DecodeSafe(SamplerFrameBuffer_TEX.SampleLevel(SamplerFrameBuffer_SMP_s, tex_coord + float2(1, 0) * texel_size, 0).rgb);
  float3 h =
  renodx::color::gamma::DecodeSafe(SamplerFrameBuffer_TEX.SampleLevel(SamplerFrameBuffer_SMP_s, tex_coord + float2(0, 1) * texel_size, 0).rgb);

sample is a waste

should load instead

[regal kayak]

idk, this is just what lilium gave us (though the decode was me making it work for tw3)

[placid siren]

it's ```cpp
abc
def
ghi

so bdefh

it's the asme ```cpp
half3 ComputeCAS(half3 a, half3 b, half3 c, half3 d, half3 e, half strength) {
half max_value;
half min_value;
bool use_luminance = true;
if (use_luminance) {
float a_y = renodx::color::y::from::BT709(a);
float b_y = renodx::color::y::from::BT709(b);
float c_y = renodx::color::y::from::BT709(c);
float d_y = renodx::color::y::from::BT709(d);
float e_y = renodx::color::y::from::BT709(e);
max_value = max(max(max(max(a_y, b_y), c_y), d_y), e_y);
min_value = min(min(min(min(a_y, b_y), c_y), d_y), e_y);
} else {
// use green
max_value = max(max(max(max(a.g, b.g), c.g), d.g), e.g);
min_value = min(min(min(min(a.g, b.g), c.g), d.g), e.g);
}

if (max_value == 0.h) return c;
half value_0 = min(min_value, (1.0h - max_value)) * (1.0h / max_value);

half value_1 = strength * Sign(value_0) * sqrt(abs(value_0));
half value_2 = 1.0h / (value_1 * 4.0h + 1.0h);

half3 computed = ((value_1 * (a + b + d + e) + c) * value_2);
computed = renodx::color::bt709::clamp::BT2020(computed);
return computed;
}

but this doesn't handle linearization and whatever

because context is linear

which is why i do ```cpp
renodx::draw::RenderIntermediatePass(
ComputeCAS(
renodx::draw::InvertIntermediatePass(_49).rgb,
renodx::draw::InvertIntermediatePass(_67).rgb,
renodx::draw::InvertIntermediatePass(_74).rgb,
renodx::draw::InvertIntermediatePass(_87).rgb,
renodx::draw::InvertIntermediatePass(_100).rgb,
_351)), 1.f);

inverts intermediate (to linear) and then the result is intermediate (to gamma)

heavily depends on the context

it honestly doesn't even matter if you mismatch top,left,right,bottom, since it's going to average them anyway. just center has to be right (c in this case)

((value_1 * (a + b + d + e) + c) * value_2); it adds/subtracts a value to c

[dusty girder]

good ole get back every sample to linear

[placid siren]

uint width, height;
SamplerFrameBuffer_TEX.GetDimensions(width, height);
float2 texel_size = 1.0 / float2(width, height);

you don't need this either since it's passed as a cbuffer

half value_2 = 1.0h / (value_1 * 4.0h + 1.0h);
https://github.com/GPUOpen-LibrariesAndSDKs/FidelityFX-SDK/blob/54fbaafdc34716811751bea5032700e78f5a0f33/sdk/include/FidelityFX/gpu/cas/ffx_cas.h#L212

[regal kayak]

I'm still so confused

[placid siren]

here's rcas https://github.com/GPUOpen-LibrariesAndSDKs/FidelityFX-SDK/blob/main/Kits/FidelityFX/upscalers/fsr3/include/gpu/fsr1/ffx_fsr1.h#L684

i think using .g is ass

though the game isn't using rcas, it's cas

the long 9 point one

rcas is for post tonemap and cas is pretonemap

rcas is meant to be decent enough for any input, even tonemapped, so it's fine for a reshade shader, but not intended to be better than cas

hence the "robust"

[regal kayak]

tried implementing the 5 sample cas you sent, but I guess these loads aren't going in grid order

not really sure how to tell which is which

[regal kayak]

actually missed that you said this, but this is what I tried lol

causes sparkly artifacts

[placid siren]

center is r4, #1411800884303626311 message make sure that when you return that it's unchanged

just return r4 and it should be identical

[regal kayak]

okay, I'll hope this is accurate 🙏

[placid siren]

starfield passed the strength, but there's probably a default somewhere

i'm still trying to figure which cas method it's doing

seems there's only two, with scaling and without. the other difference in AMD is float or half

// Annotated decompile: This shader implements a CAS-style (Contrast-Adaptive
// Sharpen) pass and is functionally very close to AMD's FFX CAS "no-scaling"
// reference (3x3 neighborhood). High-level flow matches the AMD code:
//  - load a 3x3 neighborhood (center + 8 neighbors)
//  - compute soft min/max over the neighborhood (avoid clipped regions)
//  - form a normalized contrast scalar, apply a shaping curve (-x^2 + 2x)
//  - map that scalar through per-channel polynomial/tables to produce sample
//    coefficients/weights
//  - apply weights to neighbor samples, normalize by total weight, and undo
//    an earlier color-space square with a final sqrt.
// Differences vs. AMD FFX CAS reference (important):
//  - AMD's simple reference computes a single green-channel weight and uses
//    it on the 4 orthogonal neighbors (B,D,F,H) with an optional add of
//    diagonal contributions; this shader computes two coefficient vectors
//    (r11 and r1) and therefore produces per-neighbor, per-channel weights
//    applied across the 8 neighbors (more general / per-sample weighting).
//  - This decompiled shader explicitly squares sample values early and
//    performs a final sqrt to recover color-space; the AMD snippet uses an
//    input transform (`casInput`) and may not use the same square/sqrt trick.
//  - Normalization differs: AMD uses 1 / (1 + 4*w) for the orthogonal-only
//    case (or slightly modified when diagonals are included); this shader
//    computes an explicit sum of the per-sample weights and uses rcp(sum).
//  - The decompiled shader reads coefficient table/params from `cb0` and
//    builds polynomial inputs there; the AMD reference uses const parameters
//    (const0/const1) and helper macros. Functionally these map to the same
//    role (scalar -> per-sample weight mapping) but the math layout differs.
// Conclusion: yes — it is implementing CAS in spirit and effect, but not a
// byte-for-byte copy of AMD's sample code. The comments below map the
// decompiled registers and steps to the CAS concepts and callouts above.

fsr3 rcas is just changing the scaling. you could pass PQ and be done with it, btw

[regal kayak]

like just pq encode each sample then decode at end?

[placid siren]

yep

[regal kayak]

I think I tried that

[placid siren]

in fallout4 i did something similar, but wasn't to PQ

was more HLG like

[regal kayak]

maybe not with the original shader, I'll give it a shot though

[placid siren]

float3 convertRenderInput(float3 render) {
  render = renodx::draw::InvertIntermediatePass(render);
  render /= RENODX_PEAK_WHITE_NITS / RENODX_DIFFUSE_WHITE_NITS;
  render = pow(saturate(render), 1.f / 2.2f);
  return render;
}

float3 convertRenderOutput(float3 render) {
  render = pow(saturate(render), 2.2f);
  render *= RENODX_PEAK_WHITE_NITS / RENODX_DIFFUSE_WHITE_NITS;
  render = renodx::draw::RenderIntermediatePass(render);
  return render;
}

this is what i did for fallout4 taa

where 1.0 represents peak nits

and did it in 2.2

cas is meant to be in linear

[regal kayak]

is the lutbuilder outputting in pq already?

[placid siren]

just looking at this code, i'm tempted to just make my own contraster

[placid siren]

in custom UE? srgb but with below 0 and above 1

so you'll want to retain the negatives

[regal kayak]

with the addon I mean

[placid siren]

i mean, moddded ue yes

[regal kayak]

okay

[placid siren]

save the sign, abs it, then when done, revert the sign back

[placid siren]

@regal kayak this isn't CAS by the way, at least not the current one, or https://github.com/CeeJayDK/SweetFX/blob/master/Shaders/SweetFX/CAS.fx doesn't have any of the actual sharpening math from AMD

it stops being cas right here ```cpp
// FfxFloat32 amplifyGreen = ffxSaturate(ffxMin(minimumGreen, FfxFloat32(2.0) - maximumGreen) * reciprocalMaximumGreen);
r3.w = 2 + -r2.w;
r2.w = rcp(r2.w);
r0.w = min(r3.w, r0.w);
r0.w = saturate(r0.w * r2.w);

[regal kayak]

Weird, option in game is literally fidelityfx sharpening

[placid siren]

how old is the game? also which game

this is the refactored code ```cpp
float3 SampleTexSquared(Texture2D<float4> src, int2 pos) {
float3 c = src.Load(int3(pos, 0)).xyz;
return c * c; // shader works in squared color-space and sqrt() at the end
}

float3 CAS9_Shader(int2 centerPos, Texture2D<float4> src, float4 cb0[3]) {
// load 3x3 neighborhood (readable names)
float3 a = SampleTexSquared(src, centerPos + int2(-1,-1)); // tl
float3 b = SampleTexSquared(src, centerPos + int2( 0,-1)); // up
float3 c = SampleTexSquared(src, centerPos + int2( 1,-1)); // tr
float3 d = SampleTexSquared(src, centerPos + int2(-1, 0)); // left
float3 e = SampleTexSquared(src, centerPos + int2( 0, 0)); // center
float3 f = SampleTexSquared(src, centerPos + int2( 1, 0)); // right
float3 g = SampleTexSquared(src, centerPos + int2(-1, 1)); // bl
float3 h = SampleTexSquared(src, centerPos + int2( 0, 1)); // down
float3 i = SampleTexSquared(src, centerPos + int2( 1, 1)); // br

// soft min / max over green channel (decompiled used doubled accumulators)
float maxG = max(max(max(b.g, d.g), max(e.g, f.g)),
max(max(max(a.g, c.g), max(g.g, h.g)), i.g));
float minG = min(min(min(b.g, d.g), min(e.g, f.g)),
min(min(min(a.g, c.g), min(g.g, h.g)), i.g));

if (maxG == 0.0f) {
return e; // guard, matches decompiled early return (no sharpening)
}

// compute normalized conservative contrast metric:
float amplify = saturate( min(minG, 2.0f - maxG) * (1.0f / maxG) );
// shape the response with the quadratic shaper used in the decompiled code
float shaped = amplify * 2.0f;
shaped = -amplify * amplify + shaped; // -x^2 + 2x
shaped = max(0.5f, shaped); // floor to avoid zero

// build polynomial-driven per-sample coefficients (cb0 used like tiny scalars)
// -- these mimic the r11 / r1 assembly in the decompile --
float2 scaleParams = shaped * float2(1.5f, 1.5f) + float2(1.0f, 2.0f);
float4 aInput = (float4)scaleParams.x * cb0[2].xxxx + cb0[2].yyyy; // example mapping
float4 bInput = (float4)scaleParams.y * cb0[2].xxxx - cb0[2].yzyz;

// polynomial-ish transforms, squaring/clamping similar to decompiled transforms
float4 A = saturate(aInput * aInput);
float4 B = saturate(bInput * bInput);
// combine into two coefficient vectors (per-channel)
float4 coeffSet0 = float4(1,1,1,1) + (-scaleParams.y * A + (A * scaleParams.x));
float4 coeffSet1 = float4(1,1,1,1) + (-scaleParams.y * B + (B * scaleParams.x));

// apply coefficients to different neighbors (mapping follows decompiled pattern)
// example mapping: coeffSet0.xxx -> up, coeffSet0.yyy -> top-right, coeffSet0.zzz -> left, coeffSet0.www -> bottom-left
float3 accum = float3(0,0,0);
float totalWeight = 0.0f;

// top-left + top + top-right
accum += a * coeffSet0.xxx; totalWeight += coeffSet0.x;
accum += b * coeffSet0.xxx; totalWeight += coeffSet0.x;
accum += c * coeffSet0.yyy; totalWeight += coeffSet0.y;

// left + center + right
accum += d * coeffSet0.zzz; totalWeight += coeffSet0.z;
accum += e * coeffSet1.xxx; totalWeight += coeffSet1.x; // center uses other set
accum += f * coeffSet1.yyy; totalWeight += coeffSet1.y;

// bottom-left + bottom + bottom-right
accum += g * coeffSet0.www; totalWeight += coeffSet0.w;
accum += h * coeffSet1.zzz; totalWeight += coeffSet1.z;
accum += i * coeffSet1.www; totalWeight += coeffSet1.w;

// normalize by reciprocal of sum of weights
float invSum = rcp(totalWeight + 1e-6f); // decompiled summed and rcp; tiny eps for robustness
float3 result = saturate(accum * invSum);

// undo squared color-space
return sqrt(result);
}

right after amplify = is basically not CAS

borderlands 3, 2019

[placid siren]

this is the furthest back i could go https://github.com/GPUOpen-Effects/FidelityFX-CAS/blob/master/ffx-cas/ffx_a.h

er: https://github.com/GPUOpen-Effects/FidelityFX-CAS/blob/d70012e4afff58e907b0201aac041c8a2679590d/ffx-cas/ffx_cas.h

amd code syntax is cancer

like they pay per character for function names

[regal kayak]

is it just 3dmigoto bullshit for the decomp to be using int4s for the pixel position offsets?

since it's int2s here

[placid siren]

load() is in int

you're loading pixels positions exactly from a texture

[bleak nest]

Question regarding RenoDX UE mod, the peak nits slider can fuck up sometimes or nah? Left is 3000 peak nits set, right is 4000 peak nits set.

My panel can do 3000 nits, but the game stays hard capped at diff values (well under the limit we set)

It can't be the game itself, right? Since going from 3000 to 4000 adds another 400 nits to game anyway?

FWIW, the game itself only does 1k nits max from its menu, lol.

[placid siren]

try adjusting white clip

[bleak nest]

OIC, lemme try that.

Expected behaviour then, right?

Happens in some games?

[bleak nest]

Do this while staying at 4000 (max) or keep the peak slider to my display's limits i.e. 3000?

And then play with white clip?

I can keep it 3000 on peak slider, and 1 on white clip to reach 3k nits.

or I can keep 4000 on peak slider, and 38 on white clip, to reach 3k nits.

Which is the better approach?

[dusty girder]

honestly most UE games can probably be safely set to ~20

since untonemapped isntcrazy bright anyway

and you wont loose too much

[bleak nest]

Yeah, but that's what I'm asking.

[bleak nest]

Which approach is better?

Both are leading to same results, as far as max nits go.

But idk if it's going to fuck up anything else along the way, if I do one approach than the other.

[regal kayak]

borderlands 3 looks shockingly good with the addon

[pliant belfry]

Big upgrade over Native HDR?

[regal kayak]

I'll grab a shot real quick, I didn't even compare

eh, not really, native HDR honestly looks good

though it's limited to 1000 nits and needs bff

also no paper white adjustment

I also adjusted the settings a bit in the photos I sent, was blowout restoration up to 70, saturation 55, blowout 40

this one's lined up a bit better

[pastel sand]

Hey there pals. Just a general question about Using UE "generic" RenoDX mod. I've always kind of deterred form using it since I feel like UE is so broad that I might run into issues while if I use a mod, there is a team looking after the project. Anyways...

I go to this site and if the game I'm looking for says nothing specific I should leave the config as default?

[desert heron]

leave the config as default until something goes wrong

then ask for help

[pastel sand]

Haha. Fair enough.

Oh I just saw the pinned comment and it explains it all pretty well. I was afraid of all that LUT dump stuff, but seems quite straightforward.

[pastel sand]

Ouch. Also the game seems clamped at 203 and I'm a bit clueless about all the UE mod settings.

It's Tales of Arise.

[bleak nest]

Maybe that's the occasional freakout mentioned there?

As for 203, did you try doing upgrades?

RGB10A2 and BGR8 ones.

See if that helps with clamping.

[pastel sand]

I have to reload the game for those, right?

[bleak nest]

Yeap

[coarse axle]

BL4 fix when?

[bleak nest]

Goddamn

Genuinely looks like a solid HDR title, wtf.

lol

[pastel sand]

I tried this one config, but was full of artifacts.

I'm definetely clueless about all this options. Haha. But apparently some people got Tales of Arise working with RenoDX with some minor bugs.

[placid siren]

means the game is hella custom

[pastel sand]

Lots of artifacts under that config.

[placid siren]

probably negatives that need to be clamped

the fact they're red, green, blue feels like values that teeter along 0

[pastel sand]

I could keep trying other configurations, but they seem endless.

[placid siren]

it's not normal UE, so using the UE addon is kinda shoehorning a solution

could try dumping luts to see if any of the lutbuilders are bad, but i doubt it

generally artifacts would only appear on Vanilla Tone Mapper with a bad lut builder

[digital raptor]

I just had to fix an unsafe pow in the output shader for arise to work (and any upgrades griefed the game)

looked great, so its not too custom

not sure why I had different output shaders

[pastel sand]

Meaning there's hope still? Haha.

[digital raptor]

did you disable the vignette somehow

try this build

apparently the game need r8g8b8a8_typeless upgrades depending on arise sdk config

if this doesn't work you may need to find the shader yourself with the devkit

[regal kayak]

Does it not work?

Are there lutbuilders to dump?

[coarse axle]

Haven't tried reno

Native HDR is capped to 1000

No other settings outside of max brightness slider

[regal kayak]

I’ll definitely get it working with the mod (though I’m trying to actually finish a bl3 playthrough for once)

[pastel sand]

Cool. I'll try in an hour more or less. I have Arise SDK with Emoose's ini, but I think it doesn't touch vignette.

So I just need to turn on R8B8A8_typeless to the first toggle?

[regal kayak]

This native?

[digital raptor]

yes thats enough to unclamp. but if the output shaders I added are not used by your game, you'll still see artifacts

so you may need to track it down yourself

since I can't replicate it

[pastel sand]

Like using that LUT dump thing or tweak my ini until I find what's messing with the mod?

[digital raptor]

no, using the reno devkit

the lutbuilder shaders that get automatically dumped are different ones

https://clshortfuse.github.io/renodx/renodx-devkit.addon64

[pastel sand]

No luck. What if I try with the default ini?

[digital raptor]

Could maybe work

[pastel sand]

Same :((

If there is a tutorial or some guide for the devkit and it'd benefit other users I don't mind trying. Otherwise I think is beyond my technical capabilities haha.

[digital raptor]

Then you need to download the devkit. Open it up in game, click "Snapshot" (top left) and switch to the shaders tab. You should see a long list of shaders, one of them having a dropdown that says "addon". You want to click the dump button on the next two shaders in the list

[digital raptor]

There's a decent beginners guide for modders but you honestly don't need to know all that, you just have to dump two shaders

[pastel sand]

Your latest build had the toggle preselected right?

[digital raptor]

no

[coarse axle]

Yes

[pastel sand]

Then send them to you? If it's going to be beneficial for others I don't mind trying. We can talk on DM if it suits you better not to clog this whole thread with my questions haha.

Should i use RenoDevkit along the UE mod, right?

[digital raptor]

this is the devkit after a snapshot with the shaders tab open

[digital raptor]

yes

[pastel sand]

On it.

[digital raptor]

the shaders you find are likely used by others

so yea, this might fix it for @devout grove as well

[pastel sand]

Crazy. i tohught shaders were for everybody like... An internal game thing haha.

[digital raptor]

there are minimal changes between them so the hashes don't match, theres some weirdness going on based on config in this game

[pastel sand]

Then it's like endless add-on tabs.

dump this two?

[digital raptor]

you're on the right track, can you click "more" and then "dump binary" on these two?

[digital raptor]

yep

[pastel sand]

I look at this... And honestly think...

This people are aliens.

[digital raptor]

lmao

thats assembly, we can properly decompile them, then its a bit more readable

the shaders get dumped to a new folder in your game folder

[pastel sand]

I did the dump thing.

[digital raptor]

renodx-dev\dump

[pastel sand]

Lots of files there. I will delete them and repeat to make sure it's just those two you pointed.

[digital raptor]

ah you probably clicked "auto dump", that dumps all shaders

you can easily get the hash of the shader by clicking "more" and then "copy hash" in the devkit

and then just search the dump folder for them

[pastel sand]

Got the two.

[digital raptor]

and send them here :)

[digital raptor]

lets see

this build should work. 0xDCFDF14D was the shader that needed a fix

[placid siren]

not a lut builder?

[digital raptor]

no, lutbuilder was already included

some custom output shader

had an unsafe pow

the artifacts are probably only that strong because of their custom sharpening

[pastel sand]

😐

What can I say?

[placid siren]

custom do be custom

[pastel sand]

Perfectly working.

[digital raptor]

nice

[pastel sand]

(One day I'll learn to use ReShade screenshots (I promise)).

[placid siren]

jxr's in 2025?

[pastel sand]

I'll learn now. HAHA. Just let me... Haha.

[placid siren]

https://tenor.com/view/old-code-sith-lord-vader-star-wars-gif-1414846397735946512

looks blownout to hell and back though

[pastel sand]

It's mostly because GameBar puts them all in the same folder and way more easy to keep track.

[placid siren]

i've modified some games to dump the reshade screen in to the same game bar folder (Videos/Captures)

[pastel sand]

Nice. Haha.

[digital raptor]

looks like this, so it's def real hdr

SDR | reno defaults

[placid siren]

my fault, my windows is in SDR atm, testing stuff

[digital raptor]

@pastel sand you can delete the devkit or deactivate it in the reshade menu, would otherwise cause perf issues during gameplay

[placid siren]

actually testing exactly that, auto switch Windows to HDR on game boot, and switching back on exit

[digital raptor]

ah nice

[pastel sand]

Oh wow. Looks 1:1. I was testing it against vanilla because I still have to find a good method to put SDR and HDR together. Haha.

RenoDX looked a bit more pale, but lately I've been reading and trying to understand about hue shifts so I guess RenoDX sometimes looked a tad bit more desaturated is hue correction?

In this case it's the saturation correction slider.

[regal kayak]

saturation correction usually looks a bit weird in stylized games tbh

but in general it's probably worth keeping and upping saturation a smidge instead

[devout grove]

thanks, new update fixed the issue I had as well. Renodx/vanilla

[regal kayak]

also, big fan of blowout restoration going up to ~70 in basically all games

but I also turn up regular blowout a little too

[digital raptor]

the UE mod has something called "per channel correction" to, among other things, make highlights more saturated. you can control that with the 4 sliders under strength. it has a tendency to slightly undersaturate the entire image, so saturation at 55 or even 60 then matches vanilla sdr

[pastel sand]

I won't go crazy over it. It looks fantastic on default. But trying to understand a bit better in tiny steps haha.

[coarse axle]

Game could do with some BFF

[regal kayak]

yeah it looks like bog standard UE HDR

means the addon probably just works at least

could fire up the devkit to check what upgrades it needs (bl3 had a lot of r11g11b10)

[placid siren]

RenoDX generally is more saturated in highlights and has to be dialed back, because RenoDX doesn't use perchannel

[pastel sand]

But this UE Mod uses per-channel right? Ended up setting saturation correction slider to 0 though.

[placid siren]

saturation correction doesn't add more saturation in most cases, just fixes over colored shadows

i tries to merge the per channel SDR tonemap with a neutral, by-luminance tonemap

[pastel sand]

Yes. Yes. I was trying the opposite, to make the image more vibrant, as I think SDR was. Sure some shadows are red, but SDR looked like that as well.

If I used the saturation slider, even s single unit bump was overkill compared to SDR.

What would be the downside of turning off saturation correction in this case though?

[placid siren]

can you send a picture of Vanilla and RenoDX default?

[pastel sand]

Now with saturation correction to 0.

Notice how on SDR and saturation correction to 0 the red shadows are more similar. Also in the second set, the girl's tunic is more brown and the rocks and main character skin more red.

[placid siren]

yeah, that's kinda intended because per channel ends up smearing all detail out of shadows

more accurate shadows is the consequence of fixing the saturation

red is notoriously smeared up

the per channel makes that should be dark-red/black just flat red

[swift plover]

I just set saturation correction to 100 and increase saturation to compensate

[regal kayak]

this is the way

[regal kayak]

@placid siren someone dumped this lutbuilder from BL4, decomp is giving an unexpected goto

[placid siren]

did you try the use do while?

if not, rip, tbh

maybe i can get copilot to figure out branching

[regal kayak]

fucking hell, forgot

[placid siren]

https://discord.com/channels/1408098019194310818/1408283781823070248

[regal kayak]

I should switch to that lol

use do while worked

[placid siren]

if a shader can't work with do-while it's doing some unholy logic

[dusty girder]

--use-do-while is in the sm6 tutorial

[regal kayak]

I don't check the tutorial if I think I know what I'm doing

[regal kayak]

this build should work with Borderlands 4

[coarse axle]

but

FG will flicker

[regal kayak]

maybe the fix works, I don't even have the game yet lol

[coarse axle]

tru tru, need to see if FG fix works

might just crash

[regal kayak]

I have been told it still doesn’t work

[coarse axle]

@regal kayak new

[regal kayak]

hm, I was sent this one earlier as well but it doesn't look like a real lutbuilder

figured it was garbage from precomp or from native hdr being used

maybe I'm crazy

lemme check again

oof, idk why I thought that, yeah one sec lemme add this

[coarse axle]

because I added all the BL3 upgrades

but the game is still clamped

[regal kayak]

@coarse axle

[coarse axle]

It worky

Ty very much

[regal kayak]

did you test without upgrades too?

[coarse axle]

Let me see

Sliders don't do anything

But it unclamps

Tonemapping sliders do work

Wait

I forgot they don't update in rels time now

[regal kayak]

yeah, apparently this is ue 5.5.4 so no realtime sliders

[regal kayak]

so you're saying it works without upgrades of any kind?

[coarse axle]

I am going to test that now

FG Flicker fix works

[regal kayak]

awesome

[coarse axle]

hmm it is weird to me

it has that CNN FG tearing

2x doesnt have it as much

fix is working since reshade is reporting base FPS now

fix also solved ghosting I was seeing in vanilla

on weapon sights and whilst moving guns

but the fix has its own ghosting

fix solved the disocclusion ghosting present in vanilla but now has its own tearing like and boiling/bad motion vector like ghosting/blur

Also

SDRlets truly are in shambles

[regal kayak]

bl4 honestly looks pretty great. It's insane to me how normal it is for people to see cartoony textures and suddenly be incapable of recognizing all the other rendering going on

[placid siren]

https://tenor.com/view/star-wars-gif-19575284

[coarse axle]

no upgrades needed

works fine

[regal kayak]

nice

[coarse axle]

Oops I had BT 1886 on

so the shadows are a bit crushed

[regal kayak]

so tired of the sun being a tiny dot in the sky in HDR

[coarse axle]

yep

[placid siren]

this is the type of thing where, i'm like, when in real life does the sky ever look the left?

[coarse axle]

BF1 has nice looking sun, especially the middle eastern maps

[placid siren]

sun is tiny, but could be right

[regal kayak]

is this just preset off or is the lutbuilder getting reloaded?

idk if it matters...

[placid siren]

the reflections on the water are as narrow as the sun

[coarse axle]

I took default reno then off

not sure if I should flick to native then open up menu to get lutbuilder to reload

[regal kayak]

if you already know that reloads the lutbuilder, then try that for preset off

it looks too clipped even for sdr

[coarse axle]

Reno / Vanilla Tonemapper (after lutrebuild) / Off

🤷‍♂️ guess vanilla is just that clipped

[placid siren]

if you can, do a full mod disable

i doubt it'll make a different, but man, SDR is no bueno

[coarse axle]

will be hard to line up the shots

[placid siren]

just want to see ballpark if exteriors are that blown out

[regal kayak]

wild that it's just that clipped

I guess bl3 was also bright as hell in SDR

[coarse axle]

off topic but this is killing me

the sun is hiding behind the fog / clouds

but theres still a blazing reflection on the water

because rn from this perspective, where dafuq is the light reflection source

[placid siren]

you'd think the sun is high above view

[coarse axle]

nope it is dead ahead

if you move to the right

it will appear

🤷‍♂️

SDR (removed reno entirely)

it is all just clipped to hell

@regal kayak what are your settings for BL3?

might as well try them out here

[regal kayak]

70 blowout restoration, 55 sat, 40 blowout

per channel corrections had a noticeable impact to sat in 3

[coarse axle]

I'll test those out

but damn

FG fix works to stop the flicker

but it is still WIP for the smoothness and look

when I removed it alongside reno, FG just feels better

[regal kayak]

I mean from what you posted, the native hdr looks good

seems like it's only really worth using reno if you wanna play with sliders or weren't gonna use framegen anyway

[coarse axle]

but I want to play with slider...

[regal kayak]

I'm actually curious what native hdr looks like here, since we've got the comparisons

[coarse axle]

one sec got to remove reno again

[regal kayak]

apologies for putting you to work lol

[coarse axle]

SDR / Native HDR

[regal kayak]

stupid time of day

[coarse axle]

rip

I have no control

[regal kayak]

native HDR looks solid though

[placid siren]

still per channel in native so you'll get blown to white

but does mean the game has no luts, at least

could bypass the grading entirely, probably

[coarse axle]

Theres no differences in SDR / HDR to me

in regards to grading

so if theyre using bog standard UE

theres no SDR grading bypass shenanigans going on

notice this in the tutorial area as well

Gearbox solved the UE HDR problem

just dont do any grading

[half mulch]

no gamma mismatch ?

[regal kayak]

there is

[half mulch]

well

that sdr shot is not in an hdr container

then yes

its gamma mismatch obviously

[placid siren]

i think aces hdr has more contrast than aces sdr though, might somewhat balance out

[pastel sand]

Wait I thought right was with saturation correction to 0 against left to 100. But checking now, I'd say, to my untrained eye...

[placid siren]

left is sdr

[pastel sand]

I see. True. RenoDX brings way more shadow detail. But now checking I saw that saturation correction to 0 brings even more.

I've tried matching with saturation, but no luck. It goes hard just at the slightest bump. But! Won't go crazy over it. Vastly appreciate all the time and help you people put out already.

[mild hazel]

hmm, UI brightness controlling game brightness for me

[twilit lantern]

is this for bl4?

[mild hazel]

also did have DLSS fix installed and no upgrades etc

also no mod installed

in game hdr off

[regal kayak]

New unreal, no real time sliders. That lut is already in the mod.

[regal kayak]

Yes

[twilit lantern]

Like Jon said you need to reload or sometimes pausing is enough too

For changes to take effect

[mild hazel]

I must be doing something wrong

always capped to 200 nits

reno version of reshade, dlss fix, no upgrades, that UE version, base game

[regal kayak]

Hm. Well if any new lutbuilders dump, they’ll have new in the name

[bleak nest]

Tried upgrades?

[mild hazel]

Ah ok

I tried copy and bgr10

[bleak nest]

Try the other one as well.

[regal kayak]

Try the 8 bit ones

[bleak nest]

RGB one.

[mild hazel]

aight

not super satisfied with base HDR, feels weirdly flat

will give it a shot in a little bit

[noble grove]

I agree.

[austere root]

rg10 typeless to output size didn't seem to fix black screen

[austere root]

it might only need BFF tbh i am curious to see somebody analyze it

seemed pretty punchy if not maybe too punchy

[mild hazel]

I already pushed floor down and idk, colors feel meh to me

[austere root]

I agree now, but it's by far not the worst hdr implementation i've seen

probably just UE engine standard shit

[mild hazel]

yeah its not terrible

[austere root]

it's surprisingly a game well suited to HDR which is odd

the originals were just like in teh desert haha

[mild hazel]

bout to try more upgrades see if that fixes the sliders

[austere root]

yeah lmk i am "working" so don't have time to restart the game a bunch of times

[coarse axle]

Lazorr how is the FG fix on your end

because it isnt usable for me with reno

garbles the whole screen

FG fix by itself is fine

[mild hazel]

it all works except I was stuck at 200 nits

now I cant get the game to launch without asking me to start steam

as I click play through steam

trying other reno upgrades now

[austere root]

the game is unplayable without FG hah

[mild hazel]

wdym, after modding and tuning the in game settings, using dlss performance, turning a bunch of settings down, my 5090 can hit 60 base fps (tbf I am at 5k x 2k as well)

[regal kayak]

bl3 looks great in HDR too

[regal kayak]

I wish I could help more, I don't even have the game yet

[mild hazel]

no worries I just got the game launching again, trying stuff

[regal kayak]

forge said it all worked without upgrades

[coarse axle]

what the hell is going on

one fella cant use FG fix because it garbles the screen

the another fella cant use reno becasue it is clamped

The thing worked out of the box with no upgrades outside of the one to fix black screen

but I did redo my shader cache

the game by itself also prompted a shader cache rebuilt the moment I added Reno

[mild hazel]

oh

we in business I think

yup

I am stupid, its literally the standard upgrade

[austere root]

what does this mean

[mild hazel]

I just mistakenly clicked bgr off memory the first time

[austere root]

ok it works but it crashed after a short period

FG x4 on

[mild hazel]

are you using dlss fix

[austere root]

no how do i implement that?

[mild hazel]

I am at 2x with streamline 2.9.0, FG 310.4.0, and DLSS Fix

https://discordapp.com/channels/1408098019194310818/1413548071987576862

[austere root]

do i just add that like i would reno and in addition to the reno already in the folder

and reshade 6.5.1 addons?

@mild hazel

[mild hazel]

use the reno reshade in #📝welcome

and follow the dlss fix instructions

[austere root]

ok i think i got it

hdr OFF in game right

@mild hazel

[mild hazel]

I do be getting a couple reno crashes

[austere root]

yeah i just got another one too haha

even with dlss fix installed correctly i believe

[mild hazel]

the fix is more for flickering with FG

[austere root]

yeah it's a shame that reno seems to be finnicky with frame gen

not all the time i guess

[mild hazel]

I swapped to streamline 2.8.0 and have more success

sometimes it bugs out and I have to open and close menu but it comes back

[austere root]

@mild hazel i am not on the cutting edge here what does this mean

[mild hazel]

nvidia streamline libraries

[austere root]

yeah i updated it

[placid siren]

latest is 2.9.0. did you downgrade or upgrade?

[mild hazel]

went from 2.7.3 to 2.9.0 originally

then down to 2.8.0 and I stopped crashing

I do get moment where screen more or less freezes

and I have to alt tab or open close menu for it to come back

[placid siren]

are you on bordeless (forced)

[mild hazel]

it is on in reno

[regal kayak]

snapshots should have the bl4 lutbuilders now

also presets settings for bl3 and bypasses the sharpening shader that clamps, so people don't have to fuss with it

[mild hazel]

is it in the one from an hour ago

[regal kayak]

idk when it finished compiling, just know that shortfused merged it

it was merged 2 hours ago and it usually takes a good bit to compile in snapshots

but it's definitely in there now

[dusty girder]

if it was 2 hours ago, its 100% up

[regal kayak]

yeah I checked

I just got the game, so I'll check if it'll benefit from anything else

[mild hazel]

I am trying to figure out the giant occasional stutters I get with reno

[regal kayak]

reminder that renodx usually breaks shader precomp, so if the game isn't being good about that, that's probably it

like if it didn't trigger the precomp step after you installed it

[mild hazel]

it does trigger it

and have cleared shaders/rebuilt with a couple different configurations

[mild hazel]

btw this is what I am talking about, gpu usage goes to 0, cpu to like 11

by giant stutters I mean

literally 1 fps for seconds

[regal kayak]

damn

are you using framegen and all that?

[mild hazel]

yeah, dlss fix too

I could see if it happens without

[regal kayak]

does it happen if you don't use framegen?

I haven't actually tried the dlssfix in anything yet

it sounds too unreliable currently

[mild hazel]

seems alright

without

[regal kayak]

might be worth making a dedicated mod for, since it's a big game.

[mild hazel]

yeah

[regal kayak]

ini hdr could save the day again

[mild hazel]

I would be very down for that

how hard is it to make a custom one? just time more or less?

[regal kayak]

now that I'm familiar with Musa's UE setup, it could be done today probably

but also like, the native HDR really isn't too bad

just needs bff

oh right, 50 series needs 10 bit unorm upgraded

should have made that happen automatically

[mild hazel]

yeah native isn't bad its just... idk lacking something

highlights

colors feel a bit flat

[placid siren]

aces is per channel

highlights go white

[regal kayak]

game might benefit from bgr8_typeless upgrades by output ratio

[mild hazel]

anything I can provide like logs or what not to help with dlss fix?

[placid siren]

i haven't looked at it in a while? it crashes loading, or just playing? and you said 2.9.0 is less stable?

[mild hazel]

#1411800884303626311 message

this is the primary issue I am running into now

[regal kayak]

forge also mentioned visual issues with it that didn't exist without renodx + fix

[mild hazel]

I didnt run into that myself

[placid siren]

hmm, the thing it does do per frame is give it the cloned textures, but i don't think we're cloning much here

the rest is just initialized variables

[mild hazel]

game basically hard freezes and gpu usage drops to 0

[regal kayak]

no

[placid siren]

streamline log could be throwing a bunch of errors

but we're not seeing them

my real_slDLSSSetOptions hook was bad

but i don't hink i shipped with that

[mild hazel]

unsure what this means but I have a lot of dumps in C:\ProgramData\NVIDIA\Streamline\Borderlands4

[regal kayak]

yeah I think I'll do this, maybe later tonight

[digital stone]

hello - sorry if this is a really basic question, but i was trying to get this universal mod to work with everspace 2. i saw old posts in the old HDR den discord that it worked, but it only seems to work in directx 11 for me. if i try to use the mod in directx 12 i just get a black screen + music/sound effects (i.e. not a CTD)

[regal kayak]

try upgrading R10G10B10A2_UNORM (Output Size)

[digital stone]

Thanks!

[stark shell]

To fix the artifacts you get on that ss, set resolution scale to anything but 100 😁

[wooden oasis]

Did anyone try the new firefighting game with renodx ?

[polar crest]

does this looks like renodx is working ?

highlights are dim

i mean

i need to go further in the game

but all sliders work

[rustic lichen]

Dispatch game demo. TellTale games type deal. I'll have to mess with the UE addon later. For now I'm using SK with ITM. Feels like a banger of a game though

[desert heron]

I wonder what would happen if I used this on the halo master chief collection

[desert heron]

oh
black screen in game, what else was I expecting lol

(menu is fine)

[analog light]

Anybody tried the UE version with Dragon Quest 11 S? Would love some Reno goodness but couldn't find anything on it. Game must not be that popular.

[mortal birch]

hello, sorry to bother does this works for ready or not?
because i just tried by applying this addon and also the dlss fix and the worked crashed after the first 2 intros

[polar crest]

i think dq11 and dq11s are very custom

so no dice

[fervent lodge]

Shader files for Sonic Racing Crossworlds, as mentioned in #🆘helpdesk message

[regal kayak]

seems to be working in the main menu

no upgrades needed here

clamps in the first track though

[regal kayak]

@fervent lodge just need to upgrade R10G10B10A2_UNORM by output size

[fervent lodge]

I'm Sorry, I don't know what you mean by 'already patched as part of the unreal mod'. i just dumped the files as asked

[fervent lodge]

oh? i'll give that a try, thank you so much for taking a look

[regal kayak]

it'll just work with this build

[fervent lodge]

neither using this file nor upgrading R10G10B10A2_UNORM by output size seem to have any effect

well nevermind, scene change wasn't enough, but a game restart worked

is there some resources i can use to read up on what these upgrades do? would love to learn a little more about all this

[regal kayak]

yeah you have to restart for resource upgrades

[regal kayak]

tbh idk what a good resource would be. For the purposes of renodx, you should know that 8 bit resources clamp to SDR range. Higher bit UNORM resources also can clamp. The only way to know what a game needs is to either load up the devkit and see what it's using, or, in the context of the unreal mod, to simply try out some upgrades and see what works, assuming the lutbuilders are integrated.

[fervent lodge]

i see, thank you

i'll play around with resource upgrades in the future then

[fervent lodge]

aah i see, so the generic unreal mod wouldn't just work for any unreal game? that's interesting too

[regal kayak]

it should work for most unreal games, there's just so many configurations in the engine that spawn new permutations of lutbuilder on our end. We've got a ton of them added to this mod at this point, which is why/how it's a generic mod.

[regal kayak]

fun game to play with sliders in lol

[placid siren]

windows clipboard sdr-clip

[vital geyser]

Oh there's a demo?
Is that why I see so many people test it?

[regal kayak]

idk, I bought it

I have no idea how they're this close...

maybe reloading the level isn't running the lutbuilder again

seems so, annoying

maddening game to tweak, lutbuilder doesn't run again until you go to an entirely different track lol

[vital geyser]

I do find it a bit too expensive but if it turns out that the splitscreen play actually works well I might actually reconsider

[regal kayak]

I had no interest in this game until I saw impressions at release

I loved sonic and all stars racing transformed, I just had no faith lol

game is super fun though

okay here's renodx defaults and sdr

doesn't even rerun the lutbuilder on a new track if it doesn't call for a new lutbuilder. Props to them for minimizing loading things already in memory I guess

[regal kayak]

really feel like this game got kinda screwed by aces

[placid siren]

as always

[regal kayak]

renodx letting me turn this into the cartoon slop I want

[fleet vault]

yeah neither with this file, upgrade or restarting works for me, only UI slider

[regal kayak]

Sliders aren’t real time

@placid siren would it be alright if I integrated the lutbuilder callback stuff like you have in oblivion? We could also setup a message that shows up if no lutbuilder ever gets triggered telling people to dump and post shaders.

[placid siren]

You'd have to group all the lutbuilders manually, possibly with a macro

[regal kayak]

maybe I should actually look at the oblivion implementation to see what I'm trying to get into lol

oh, yeah there would need to be a macro for this to make sense

I'll have to see what I can do, gonna have to familiarize myself more with how everything works 😅. It's a problem I really think we should solve though since it's gonna affect most new releases now.

and it's unreasonable to expect the average person to have any idea why it wouldn't be working

[placid siren]

I wanted to make cmake generate a macro that is like __ALL_{FOLDERNAME}_SHADERS but I got lazy

[tall wedge]

here are some LUTs for Frostpunk 2:

had to upgrade R10G10B10A2_UNORM to get display

[sturdy lagoon]

Looks fine tbh I would play like that

Very fitting

[broken smelt]

Tchia works with B8G8R8A8_TYPELESS Output Size, cutscenes clamped/SDR

[fervent lodge]

so, funny thing about sonic racing crossworlds, it's back to being capped at game brightness as soon as resolution scale is not 100%

[severe grove]

It is insane with the huge highlights like those ones did not get an actual native HDR into the actual game without the mods, as the rendering style is made for HDR usage. Even the Engine.ini HDR config has the similar highlights as the mod (as I used the Engine.ini config in the Open Network Beta).

[regal kayak]

set the upgrade to aspect ratio instead

I'll make sure that works really quick

[fervent lodge]

it works indeed, thank you!

so why would i use output size instead of output ratio to begin with?

[regal kayak]

RIP, doesn't work on ultrawide lol. I'll have to make a build with special upgrades

output size upgrades resources that are sized to window size, while aspect ratio will upgrade sub native res resources

in general you want to use the minimum amount of upgrades necessary since upgrades can cause issues.

[fervent lodge]

huh i see, thank you

glad it works at 16:9 aspect ratio then. got a 4090 so i figured i might as well use it to play at a higher res scale

60 fps lock is a bummer

[severe grove]

The game's FPS is tied to the speed. Unstable FPS will slow down the game and worse DC'd in online races for everyone as error 1-6-0, despite in UE5. I don't know why they hard coded as that. This is a kart racer, not a fighting game (when frame input is important).

[regal kayak]

• add explicit rgb10_unorm 16/9 upgrades for sonic crossworlds
• set rgb10_unorm upgrades by aspect ratio for sonic crossworlds (in case of ultrawide mods)

[fervent lodge]

oh, it works out of the box with this now?

[regal kayak]

yeah

[severe grove]

You can freely add it to the Legend list instead of placing on Unreal Engine Multi-Game Mods list: https://github.com/clshortfuse/renodx/wiki/Mods

[regal kayak]

it's still just the unreal mod

I should add it to the list though

needs to get merged first

[fervent lodge]

that's fantastic, thank you

[regal kayak]

@placid siren could you take a look at my PR? I mostly just want Sonic to be in there asap.

[mint escarp]

@barren nexus is this it?

ok

[mint escarp]

off

[rustic lichen]

unreal engine TinyGlade clone

game is called Outside the Blocks, there's a demo out for it now

tried getting RenoDX to work but could only get the UI slider to do anything

[placid siren]

did you get _new_ lutbuilder?

[rustic lichen]

I didn't

I exported and it was ones it already had

[placid siren]

if you said tiny book shop, i would jump, since my wife asked for the game

but tiny glade? i sleep

unless it's free/xbox

[rustic lichen]

Outside the Blocks, free demo

the game itself isn't out yet

added to the worklist

you need to enable descriptor tracking for dx12 in devkit options

doesn't run every frame, maybe?

it...should, unless the metrics aren't right (different dimensions) or there's no lut builder

renodx::mods::swapchain::swap_chain_upgrade_targets.push_back({
    .old_format = reshade::api::format::r10g10b10a2_unorm,

%"hostlayout.class.StructuredBuffer<FPackedNaniteView>" = type { %hostlayout.struct.FPackedNaniteView } i don't think that's your lutbuilder

it upgraded it though

InstanceCullBuildInstanceIdBufferCS

but yeah... 1.05

that's this? #1411800884303626311 message

yeah, that is lut builder

a really simple one

sdr lut sampling in there

float4 _246 = t4.Sample(s2, float3((cb0_034z * TEXCOORD_4.x), (cb0_034w * TEXCOORD_4.y), ((((cb0_026y * _226) + cb0_026z) * 0.96875f) + 0.015625f)));

31/32 = 0.96875

and some smoothstep

float smoothstep (float edge0, float edge1, float x) {
   // Scale, and clamp x to 0..1 range
   x = clamp((x - edge0) / (edge1 - edge0));

   return x * x * (3.0f - 2.0f * x);
}
