Fallout New Vegas

[dusty lynx]

actual question, does FNV support spot lights?

[brazen oyster]

no

[dusty pivot]

no

[brazen oyster]

bethesda removed them

because

[dusty pivot]

basically, since it's forward, shaders only handle the basics

[brazen oyster]

I mean they are still there

[jagged chasm]

If anyone wants to buy my 3080 off me, I’ll sell it cheaper than msrp. I need that 4090 vram.

[brazen oyster]

just unused

I wonder if NiDX9LightManager can be brought back to life

[dusty lynx]

ah, and I'm assuming there's probably like no proper engine or GECK support for them? cause that might still make a case for wanting to use usda based lighting

[brazen oyster]

nope

[dusty pivot]

lights in forward are simple: pass their data to the shaders, loop in the shader and add all lights from the scene one by one

[brazen oyster]

bethesda made their own spotlights in FO4

[dusty pivot]

if you want spotlights, your shader has to know how to light the object with the data passed to it

[brazen oyster]

gamebryo lighting system is unused

[brazen oyster]

replaced with a worse bethesda version

because of fucking course

[brazen oyster]

you can see this theme across the whole game

[brazen oyster]

that's why calling this engine gamebryo pisses me off

it's not GB

[jagged chasm]

It’s not as bad as the sims 2 engine right?

Right ?

[brazen oyster]

if it were, we wouldn't have all those issues

[brazen oyster]

nah

can't top that

[jagged chasm]

Are we able to intercept this loop and just forward them to d3d9 calls ?

[dusty pivot]

it's not like that, you can easily do your own loop

this is a loop happening in the shader, but the scene graph has all the lights

iterating through the lights of a cell is easy

but you'll need the scene graph decoded and accessible in your plugin

[jagged chasm]

My pizza bounty is still on the table @dusty pivot

[dusty pivot]

https://github.com/mchaptel/TESReloaded10/blob/78e07db015b4adbf5f88d38fb16f889862d08cd0/TESReloaded/Core/ShadowManager.cpp#L663

this is the function I use to get all lights and gather the info required to do a lighting pass

basically NVR tries to take a page from the deffered book to render a single texture with all the shadows of the scene, then composites it on top of the image to avoid having to modify all the individual object shaders

I hope that eventually I can bend this renderer to output the passes a deffered renderer has, then do the lighting in deferred

that's what I'm hoping your guys will save me from having to do

[dusty lynx]

@dusty pivot what branch is best to work off of?

[brazen oyster]

nightly

[jagged chasm]

Considering how fast this is moving, Mark said they weren’t even expecting new Vegas to work this year, I’m sure we’ll have it figured out soon enough

[brazen oyster]

is the main

[dusty pivot]

my fork isn't the main one, so I keep main clean. Nightly is the aggregate of all the changes made since the fork was done, and whenever I publish a new nightly I (usually) merge the new commits to it.

I haven't for the last couple of times because the features have been a bit broken, so the latest changes are on the pointlights in exterior branch. I'll probably merge them soon

[dusty lynx]

tomlplusplus missing?

[hearty crane]

The face difference 🫣

[dusty pivot]

submodule, you need to add it

https://stackoverflow.com/questions/16773642/pull-git-submodules-after-cloning-project-from-github

[dusty lynx]

I cloned with submodules, there's no .gitmodules in the repo though

[dusty pivot]

really? There should be?

https://github.com/mchaptel/TESReloaded10/blob/pointlight-shadows-in-exterior/.gitmodules

[dusty lynx]

ah fuck okay, cause I didn't clone directly to nightly

[dusty pivot]

yeah having main so far behind is annoying, maintainer of official repo is mia

(busy with work)

[brazen oyster]

yours is the official one to me

[dusty lynx]

bleh, tomlplusplus is just giving me tons of "error C2131: expression did not evaluate to a constant" on it's asserts, release build seems fine though

[dusty pivot]

strange...

[brazen oyster]

Alenet's XML won...

[dusty pivot]

worse case scenario, download artefact from tomlplusplus and copy paste 😬

[dusty lynx]

Alenet couldn't maintain a basic git repo

[brazen oyster]

[dusty pivot]

loooool didn't see the emoji code hahaha

oh, Alenet

[brazen oyster]

he's thinking about it

[simple gazelle]

Do you know why the hashes are unstable? If you can figure out what properties are constantly changing, there may be ways to fix it - either in the game side or the Remix side

[jagged chasm]

I suppose it’s from the verticies being captured from shaders.

Oh another note: Can I just remove the normals from the bsa files to disable them?

[jagged chasm]

I know there’s a way to modify the shaderpackage itself. So we could possibly make a GitHub issue with the shader sources and see if you guys can figure out what about the shaders cause it to be unstable.

[dusty lynx]

why does Framework.h redefine assert?

[dusty pivot]

I have absolutely no idea about that part of the code

there is a lot in this plugin I still don't understand very well, in the hooks part

lots is uncommented and would basically require intimate knowledge of the memory addresses

[dusty lynx]

oh this hurts ... Alenet made assert always static_assert, and then is using assert instead of static_assert in places

[dusty pivot]

I honestly would love a pass done by someone who knows what they're doing because a lot of this is above my head haha

not to say that I don't understand why replacing core c++ namespace is horrendous of course

[brazen oyster]

AlenetC++

[dusty lynx]

this shouldn't be too hard of a PR, it's mainly just struct size and offset checks

[brazen oyster]

do not look at settings hooks

[dusty pivot]

btw feel free to join the discord & create a thread in development if you want, I don't want to pollute this channel too much with stuff that might be irrelevant

[dusty lynx]

is Alenet still around in there?

[brazen oyster]

no lmao

[dusty lynx]

good

[dusty pivot]

no, he only comes by twice a year

it's pretty chill these days

[jagged chasm]

I’ll be able to test any builds you guys have later today by the way

[scarlet pond]

I can’t seem to get this to function

[jagged chasm]

RtxRemix ?

[scarlet pond]

Remix for new vegas it’s side loaded it but I can’t seem to bring the alt+ x menu up

Can tell it’s running it I’m just not seeing any shaders

[jagged chasm]

Oh. Make sure bUse Keyboard=0 is set in the perfs ini

[scarlet pond]

The my games ones?

[jagged chasm]

Yea

[scarlet pond]

Can seem to find it in prefs

There’s bBackground Keyboard = 1

[jagged chasm]

That’s the one

[scarlet pond]

Groovy

[jagged chasm]

Needs to be 0

[scarlet pond]

Also wowsers 19fps in goodsprings

Still the same

[jagged chasm]

Oh there’s a lot of textures and stuff to toggle in order for it to work

[scarlet pond]

cant seem to open up the menu to do so

the shortcut just doesnt do anything

[jagged chasm]

Do you have a controller connected?

[scarlet pond]

i dont think so no

ive checked my ports and theres nothing else in

My gpu is pinned at 100% and there’s no physical difference lol

[jagged chasm]

Uh. Might need to toggle the direct input or the other input tweak in bridge conf

[scarlet pond]

cant see a bridge conf

[jagged chasm]

It’s in the trex folder

[scarlet pond]

Gotcha

I’ll try this

Nope still no access to the menu

I’ll just run across the whole breaker

[jagged chasm]

Sorry I can’t be more helpful. I’m working on getting a guide written for this but it keeps having to change as we develop it more

[scarlet pond]

Yeah I know finding the articles and read mes is a nightmare in these early stages

I’ll have to keep trying could you post your configs

[hearty crane]

According to Wall_soGB the ini in The main dir (Fallout_default.ini)dictates what it written in /my games/FalloutNV one
cant say for sure
@scarlet pond I also have :bBackground Keyboard=1 (fallout_default.ini) also same in the other(in documents)
never had a problem with input in this game(except when the mouse is invisible, alt+delete solves that easily)

[scarlet pond]

The default is the default then?

Remix aasaaaaa why you no let me use the menus

[hearty crane]

@scarlet pond How are you runiing it in windowed mode? from where?

[scarlet pond]

I’m running it in windowed mode

The prompt comes up at the launch but using the shortcut does nothing

[hearty crane]

My shortcut (is the launcher) runs in normal window.And in options windowed is NOT selected.

[jagged chasm]

It’s something with the background keyboard book and one of the input tweaks with bridgeconf

[scarlet pond]

Odd so having it windowed stopped the thing from doing the thing

Right so when selecting textures am I literally just clicking them in the dev menu

[hearty crane]

my bridge.conf is stock and coomands are with # , i think if a command has '#' , its disabled/considered as a comment therefore a default is used(dont know what defaults are for these two commands).

[summer cargo]

Pretty much, # is used as a comment marker.

[scarlet pond]

Nice

[summer cargo]

Can't have DXVK trying to read all those digs at The Sims 2. 😏

[scarlet pond]

Haha

[jagged chasm]

Those get applied by the exe name. Lot of game specific tweaks get applied the same way.

[scarlet pond]

So do I leave the normal maps unselected

[jagged chasm]

No they all need turned off

[scarlet pond]

So just select textures

[jagged chasm]

It’s a bit of a chore. You can use the console command tlb to turn them off tho

[hearty crane]

If we can turn them off from the game, otherwise ignore textures doesnt work for these normals.

Tlb also disables some terrain , last couple of times i checked

[scarlet pond]

It’s like playing cookie clicker with textures

Ah sheet

I done clicked them all in the one catagory

[jagged chasm]

I talked through how I’m going to try and do that with anchor earlier today. Hopefully I’ll have something tonight.

[scarlet pond]

How does setting emissives work

[hearty crane]

@scarlet pond Currently , treat the Worldspace UI as emissives.

[scarlet pond]

Gotcha

[jagged chasm]

Ah is that how you got them to work?

[scarlet pond]

Now would I use the normal maps in the emmisives too or

[hearty crane]

@jagged chasm Ye, i thought ye knew. I would have told you.

[scarlet pond]

Or does remix just take the colour

[jagged chasm]

Normals need to be set to ignore

[scarlet pond]

So all normals need to be ignored

[hearty crane]

@scarlet pond With Emissive it takes the color from the texture/geometry, if a game supports add textures as lights(diffrent tab/category) those are same Bright/light color.
(new vegas cant use this)
do mind if you ramp up to much the emissive intensity the color will be bright but you wont see much of the texture.

youll learn fast.

[dusty lynx]

#1106553248590090351 message

I'd probably just start with all these configs first

[scarlet pond]

There’s pre-made ones? I’ve been looking ages

[jagged chasm]

Those are out of date now but still a good starting point

Learned a lot in the past few days.

[scarlet pond]

Are most of the basics like normals being ignored and light textures done?

[jagged chasm]

I’ll focus on updating my guide tho, I really want to make it so this is “easy” to get running.

[dusty lynx]

also I had to set "bBackground Keyboard=0" in Fallout.ini for it to work, and FalloutCustom.ini seems to not work at all for me

It should be decently easy to just unpack the game's archives, scan through all the normal maps, and generate an ignore list

or hell, even convert them all to octahedral normal maps and make them work through a usda

[scarlet pond]

Odd I keep adding normals to the excluded textured zone and goodsprings building flashed green like I’d completed an objective

[hearty crane]

I updated the main post

[dusty lynx]

textures flash green when you hover over them in the ui so you know what you're changing

[scarlet pond]

Ah

[hearty crane]

When you get et working:
Ye basicaly got 3 ways of lighting currently(separate ways of controling the light).
1.Emssives(worldspace UI)
2.Sky texture
3.fall back light | acting like sun or a sphere/you choose

[dusty lynx]

currently messing around with the idea of making an NVSE mod to send light info to remix via the normal fixed function api

[hearty crane]

et was pinned couple of days ago

[dusty lynx]

oh, I checked pinned just now and it said nothing, but now it says it's there

[scarlet pond]

F it crashed

[hearty crane]

I updated the main post today, did you use the dxvk -remix (latest release # 75 )and the hack ?

[scarlet pond]

i see the hack and dxvk

i thought it would be similar to morrowind where people would have pre done configs

[dusty lynx]

a lot of this stuff is only barely working like, as of a couple days ago

[scarlet pond]

ah noted

so if i can manage to get a somewhat working version ill post it here

[dusty lynx]

nightly build of dxvk-remix is needed to get rid of the intense shaking
and bridge hack is needed to get rid of multithreaded crash issues

[scarlet pond]

Honestly I’m pretty new to the whole GitHub stuff

Everything I’ve downloaded for rtx remix has been sending my windows defender insane

[hearty crane]

Now it doesnt start for me either, but i messed about with settings in fallout_default. 😄

[scarlet pond]

Hmm the game keeps crashing I think it’s running out of memory

Does nvse make a difference

[dusty lynx]

go into .trex/bridge.conf and change # client.setExceptionHandler = False to client.setExceptionHandler = True
it should then make a .dmp file when it crashes, you can send it to me to see why it's crashing

[hearty crane]

uGridDistantCount=20
uGridsToLoad=5
I had these to 35 and 7 , didnt want to start up to the menu.

[scarlet pond]

Thanks

[hearty crane]

Tho now with latest Dxvk-remix the pipboy doesnt show anything.Layering problems

[scarlet pond]

Ah

It seems to be crashing sooner and sooner

[jagged chasm]

https://github.com/adamplayer/RTXRemixGuides/tree/main/Fallout New Vegas Here's a quick little guide.

[scarlet pond]

Managed to get a few things working but it’s gonna be a two parter I’ll do some more work on it tomorrow morning hopefully I can get the emission textures working because it’s rather dark in game at the moment

Can’t seem to setup the sky texture which is an issue

[brazen oyster]

uGridDistantCount doesn't exist fyi

[dusk rock]

i got a ping here but can't find it

[hearty crane]

@dusk rock Someone said the main post should be pined, i replied that you pined et
I update et the post recently, might have cause some sort of latency in the pin et self, dont know

[dusty lynx]

@brazen oyster noticing there's some kind of offset, testing lights in an interior, the world roughly renders around the 0 point but the world location of the lights are like 2500 units away

oh, nvm it's just the player camera? position

[jagged chasm]

Damn that was fast

Like I thought this would take months.

Y’all getting this figured out in a week since it was able to be injected.

@dusty pivot can rest easy now

[dusty lynx]

I'm so far unable to actually get the lights to line up properly

[dusty pivot]

It is possible that the lights are not lined up in the game itself

[hearty crane]

Emissive texture?

[dusty pivot]

They've been placed a bit questionably sometimes

[dusty lynx]

more so that none of the various camera positions or camera world transforms I've tried seem to work

[dusty pivot]

NVR has a debug shader that lets you visualize their position

[jagged chasm]

Time to go through GECK and fix them all

[dusty lynx]

I'm currently just using the player position but that makes it so crouching moves the lights

[dusty pivot]

Oh, NVR also does reconstruct some of those matrices

I believe in the render manager?

You should be able to find how to get the world transform I think

[dusty lynx]

All the geometry that remix sees seems to be oriented around the camera (probably why none of the geometry hashes are stable), so to also get remix to see the lights I have to orient them relative to the camera

[hearty crane]

Looks like a direct light with slightly high effect radius (or default cause for direct lights lower radius may be better to give contrast to soft shadows from emissives ).I cant get any direct lights thats why ets odd to me.

Direct lights in a vertex capture give psychadelic lights.disperesed everywhere, pulsating
In Stalker CS and here.Not claiming its a rule

[jagged chasm]

He’s just testing still

[hearty crane]

We all are 😄

[jagged chasm]

Does this explain why the world appears to be Z- oriented in captures?

[jagged chasm]

Also @simple gazelle there’s your likely answer on the hashes

[dusty pivot]

Yeah I think in this engine the world moves around the player

But camera and player position are different i believe

Hence the crouching issue

[hearty crane]

@dusty lynx Go here and tell me the total number of lights

Render->lighting->lighting statistics

[jagged chasm]

What did you do to get that many lights.

[hearty crane]

🤣 🤣 🤣 🤣 🤣 Nothing i was surprised too. The total number DOESNT LIE.Still zero, its in the menu so i dont know what reading from the background.

[jagged chasm]

That light source he showed was the one from in the game, captured used NVR, and then given over to Remix. So it’s not like a manually placed light or anything.

By default, there’s no light sources visible to RTXRemix from the game. Apart from emessive textures as you know. The translation patch that BlueAmulet has built off NVR, I believe, let’s the light sources be captured by rtx remix.

[hearty crane]

The one he said he will try to FFP Lights through NVSE/NVreloaded?

So thats why you said , THAT WAS FAST!!!

[jagged chasm]

BlueAmulet be sniping Nvidias internal Jira queue.

[simple gazelle]

Ah, that usually means the world is being moved around a still camera, which probably means the original game did the camera via vertex shader instead of the FFP.

It might be possible to mod the game to pass a camera transform to FFP and just the identity to the vertex shaders, but I doubt that will actually be as simple as that sounds - especially if they use different camera / player transforms for different draw calls

[jagged chasm]

A new quest has been discovered

[viscid grotto]

does new vegas work yet

the game I mean

[sterile hinge]

Start scrolling 😂

[hearty crane]

Read the main post, i did an update.Things changed drasticaly.Press the pin above,and JUMP 😄

[viscid grotto]

oh shit

uh

alt+x doesn't make the gui show up

nvm

wait no

it still doesn't

nvm

had to turn of background keyboard

uh fuck

I can't skip the intro cutscene now

or go into the console menu

I see what the problem is

I have my controller connected

[jagged chasm]

Did you follow my guide

[viscid grotto]

guide?

[jagged chasm]

https://github.com/adamplayer/RTXRemixGuides/blob/main/Fallout New Vegas/README.md

I made it just for you :^)

[viscid grotto]

ah, ok

is it just me or are the normal maps being treated as regular textures

[dusk rock]

looks like it

looks like an alien too, lol

[viscid grotto]

how do I get rid of normal maps

[jagged chasm]

Gotta mark them as ignore

It's a bit tedious

The rtxconf I posted has quite a few but

[viscid grotto]

tried your confs

[hearty crane]

This is how et looks when you add light to a texture

[simple gazelle]

BTW - when sharing confs, yall also need to make sure you're using the same in-game graphics settings. Stuff like changing the texture quality can change the texture hashes

[hearty crane]

@viscid grotto Disable alpha blended,and /or emissive blend overide.

When path tracing passes,Emissive blend has some normal maps act as emissives, not all of them.
Disable emissive blend overide and they vanish

[viscid grotto]

that just makes most objects vanish, and the screen still flashes pink

[hearty crane]

There must be some texture classified as "add light to texture" . You running NVSE/mods or Stock FNV?

[viscid grotto]

stock

[hearty crane]

Search for a texture thats placed in "add light to texture"

[jagged chasm]

That never seems to add light to textures from my experience.

In this game that is

[hearty crane]

It doesnt(in vertex capture based games), but it does add that pink random brightness that he showed in the video above
although it does add lights in Max payne 2, Hitman 2, The punisher,Operation flash point , Swat4 also [dx8 mostly]

[jagged chasm]

I'd recommend following the Viva New Vegas guide

[dusk rock]

i'm still upset that they disregard all AI upscaled packs as "bad" though

[jagged chasm]

Who? Wall_SoGB?

[dusk rock]

the guide you mentioned

[opal crystal]

Well, a lot of them are low quality.

There probably exists a good one out there.

[dusk rock]

the way it's worded pretty much discredits the method entirely

and while i agree that many are poor, just saying any AI upscaled pack is bad isn't right imo

anyway, lets just move on from that

[fervent void]

In my experience with AI upscaling, it's not that it is bad per se, it's just that it is often uneven in terms of quality. I have seen AI upscaled textures that almost looked as good as if they were done by hand and then others that looked like it had no idea what it was even supposed to be doing, and that is with the exact same model being used for both the good and the bad. Overall I do think it's better than nothing most of the time, though.

[summer cargo]

I think it really depends. If you noticed the upscaling artifacts in a situation where it wasn't really applied to an important detail, your workflow is flawed and it's worse than nothing.

Text is a particular no-go where it feels cheap and lazy, and the only thing worse than trying to read tetris blocks on the wall is to try to read a poster that belongs in City17 or Courascant.

[dusk rock]

a good texture pack creator will switch between different AI models depending on the texture, and will ensure they all look good afterward. if it doesn't, then it takes manual work

any texture in an AI upscale pack that doesn't look natural is because the person who made it either missed it, or didn't take the time to make sure it looked good

[summer cargo]

More than anything there are certain artifacts that can be diminished, like white outlines along transparency or bad tiling, and failure to account for that will instantly discredit any other work that went into the model.

[dusk rock]

a cheap AI upscale without any effort definitely isn't worth using. i just wish they had worded it a bit better, that's all

[dusty lynx]

@jagged chasm NVSE plugin to pass lighting information to RTX Remix, point lights only no sunlight
Obsoleted by #1106553248590090351 message

[jagged chasm]

[dusty lynx]

though sunlight (fake dummy one for test) was having the issue that since stuff behind you gets culled, it just leaks pretty badly, some anti culling system patch is definitely needed

[hearty crane]

I didnt expect USD to export cause of the vertex capture(i think it doesnt export from Stalker Clear Sky,maybe i need to retry)

[dusk rock]

it doesn't export fully in Barnyard right now either iirc

also heavily shader based

[hearty crane]

Pretty good!!! @dusty lynx
showed 8 lights in total outside goodsprings(got inside, same : 8 lights).Adding lights to texture doesnt work.

To the Saloon!!

known issue:Culling leaks more light then there is... in this scene

[dusty lynx]

also probably an issue but D3DLIGHT9 wants a Range and I could not find such a number on the NiPointLight, attempting to calculate it from the attenuation numbers wasn't working out, setting it to 0 hoping remix would figure it out failed. Also I don't know what values are in the specular color cause they're not 0 to 1, and also not 0 - 255

[dusk rock]

it's just shocking how good that looks, even with the old assets

great work

[jagged chasm]

I wonder if the light hashes are stable

[dusty lynx]

they are camera position relative so probably not

[jagged chasm]

We could just modify them using mod.usda if they are

Nonetheless, this incredible progress.

Thanks for all this work @dusty lynx

[dusk rock]

how difficult would it be to convert this to work with FO3? or would it work with FO3 through TTW?

[hearty crane]

@jagged chasm In world transform/ fused world view,they dont move with the camera.If thats what y'all mean

[dusty lynx]

I think you'd have to do it via TTW

there's several hard coded addresses in NVR that wouldn't translate over to FO3

[jagged chasm]

Nah, it's the hash value for the light itself. You'd could check if the light hashes stay the same between captures.

[hearty crane]

Dont know how to do that.

[jagged chasm]

All good, I'm going to look at it here in a bit.

Plus try getting some PBR materials in game.

[hearty crane]

Now how about that...

[summer cargo]

This looks incredible.

You're all amazing.

I don't even like New Vegas. 😅

I'm genuinely convinced to give it another shot now.

On the topic of emissive materials-- my new build of PBROven was uploaded publicly and will now enable emission, and if an emissive map exists in the texture output directory, it'll enable that too.

It's still a mess so don't mess around tagging, but I'll try to give it a go as soon as I can for FO3.

https://anchorlightforge.itch.io/pbroven The version you'll want is 0.0.20 Alpha which includes the rtx.conf parser so anything you mark as an addlight will automatically be emissive, adding a toggle for this is on my to-do list but I'm not sure when it'll be in.

I hope it helps, sure wish I got this done sooner but it felt like every time I thought I was getting somewhere a new problem came up. Such is software dev. 😂

[hearty crane]

TTW will make et work!!! tho i had lot of trouble installing that one(year or two ago).

[dusty lynx]

@summer cargo were you the one doing stuff with xxhash?

[summer cargo]

I think that was AdamPlayer, though I did find a C# implementation I don't think I'll get into that until after I ship pbroven 0.0.20 stable-- then I'll probably write a separate app for it to see what happens.

[dusty lynx]

something I want to try doing is writing something that takes an extracted bsa from the game and automatically hooks all the textures up as a usda

[summer cargo]

If you can get the textures into a single folder I can make a super hacky prototype using PBROven as a basis.

[simple gazelle]

oooh, we actually use the D3DLight9's range to guestimate the actual physical properties of the light... you can probably find the code for that in dxvk-remix and then base your settings off what Remix does

[dusty lynx]

are the attenuation values used at all then?

[simple gazelle]

https://github.com/NVIDIAGameWorks/dxvk-remix/blob/main/src/dxvk/rtx_render/rtx_lights.cpp#L126

That code is what we use to try to calculate a radiance to make a physically realistic light that is similar to the game's light. D3D9 lights can have completely physically impossible values, so we can't always get it exactly matching, but that code works fairly well most of the time

Unlike most of the codebase, that function is also really well documented and explained

[hearty crane]

Camp McCarran.
Emissives OFF

[jagged chasm]

That’s what I was trying to do but I could strip the file headers properly in an automated way.

[dusty lynx]

wouldn't it be the DDS data without the header?

[jagged chasm]

Yea but my smooth brain only knows how to use Python at a pretty basic level.

[dusty lynx]

with open('texture.dds', 'rb') as f:
  data=f.read()
hash(data[128:])

[jagged chasm]

I think it’s easy to do in c++ cause there’s the nvtt sdk that handles it.

[jagged chasm]

Tried that. Got a different hash than the game

[dusty lynx]

hmmm

yeah no byte offset matched the hash.

[hearty crane]

No emissives! 👍

Outside ,unfortunately there are no lights(maybe the loading didnt go right)

[jagged chasm]

I suspect that having the gpu load the texture and then hashing the data in memory just like remix is the only way I can think of it that ensures it.

I know nvtt can do that but it’s sdk is in c++ which I only know vaguely.

[jagged chasm]

The game looks so good for even just being diffuse textures.

Can’t wait to put all the emissive and normals back into the game.

[dusk rock]

how does the strip look?

[summer cargo]

😬 Is this with my tool and if so did it break on you?

[dusty lynx]

@jagged chasm @summer cargo figured out the hash, it's the xxh3_64 of only the first mipmap

[dusty lynx]

[ornate marlin]

It's easy now TTW just basically converts fallout 3 into a standerd mod or dlc

[short scaffold]

wow...good progress

[dusty lynx]

Going to the store now but I'm going to try figuring out usda replacements and getting vanilla normal maps working

[jagged chasm]

Here's a python script that returns off the hashes in the form HASH, in a specified text file. Thanks so much @dusty lynx

Oh lemme add the 0x prefix that the rtx.conf uses. Just saw that it kept that

Here's supposedly all the ui textures in the game

[summer cargo]

That 0x is the most inconsistent thing in the world. 🙄

[jagged chasm]

And all the normals...

Also an updated python script that handles a filter

xxhash-textures.py Texture/Path output.text [optional string filter]

[brazen oyster]

Range huh

Specular, red

Is the range

It's reused

Light specular doesn't exist

[summer cargo]

@jagged chasm This is madness. You should 100% tidy this up and post it to #1095534398134300682 for other developers to use, I think this is going to be a huge deal for a lot of games where this type of texture extraction is possible.

I'm kind of awestruck right now, you all got this done so quickly...

[dusty lynx]

heh, kind of thought that value looked like a range, I ended up using specular red for the range in the mod

[brazen oyster]

Good instinct

[summer cargo]

I was going to say that PBROven might actually serve a purpose here but it looks like ignore_material is being ignored by the final USDA. 🙄 Guess I'll ship that build now.

[jagged chasm]

Oh no I broke this somehow

[summer cargo]

Okay, new build will go up in a minute. Mostly just small tweaks but the tool now marks IgnoreTexture as ignore_material in your final replacement USDA; usually not necessary but sometimes Remix just likes to ignore texture input.

[dusty pivot]

Nice one, check out again the function I sent it you want, it also handles culling and disabled lights

Amazing progress!

[dusty lynx]

would you happen to know of a way to disable frustum culling?

[brazen oyster]

in the accumulator

do you want to disable it only for lights or, for everything?

[dusty lynx]

everything, cause otherwise it makes lights leak a lot

[brazen oyster]

okay, expect unplayable game then

sec, I'll find the code for it

[jagged chasm]

You can enable culling in remix itself to prevent it from getting too crazy

[brazen oyster]

BSCullingProcess* __fastcall BSCullingProcessCreateHook(BSCullingProcess* apThis, void*, void* apVisibleSet){

    ThisStdCall(0x4A0EB0, apThis, apVisibleSet);
    apThis->kCullMode = 1; // ALLPASS 
    return apThis;
}

WriteRelCall(0xC51887, BSCullingProcessCreateHook);

this will disable the culling on scenegraph's culler

does NVR even ship with this class?

no lmao

[jagged chasm]

Turns out giving the rtx conf all those hashes is a bad idea.

[brazen oyster]

class NiCullingProcess {
public
  void* vftable;
  bool m_bUseVirtualAppend;
  NiVisibleArray *m_pkVisibleSet;
  NiCamera *m_pkCamera;
  NiFrustum m_kFrustum;
  NiFrustumPlanes m_kPlanes;
};

class BSCullingProcess : public NiCullingProcess {
  UInt32 kCullMode;
  UInt32 eTypeStack[10];
  UInt32 uiStackIndex;
  BSCompoundFrustum *pCompoundFrustum;
  BSShaderAccumulatorPtr spAccumulator;
  bool bRecurseToGeometry;
};

the offset of kCullMode is +90h fyi

[jagged chasm]

By the way, the massive amount of pink light being emitted may be from some weird double stack texture bug. I get a second instance of an object sometimes and it has the same corrupted (?) pink shimmer to it.

[brazen oyster]

pink is usually missing texture

although missing textures can also just swap between last used one

[summer cargo]

I'm personally experiencing this in Anachronox and it seems to be related to loading replacement usda's; sometimes it also comes in bright orange. A game restart after the mod finishes first-time loading usually helps.

[brazen oyster]

this will be geck in 2015

[jagged chasm]

Was GECK able to have the correct coordinates defined Most of my captures from fallout are inverted

[summer cargo]

I'm noticing that too in FO3. Unfortunately this might be a case where Omniverse is the limiting factor.

I hope we can flip +/- vertical though, and maybe even an X Up option just in case.

[brazen oyster]

When I was importing maps to blender I remember rotation being inverted on some axis

that was long time ago and I don't remember details sadly

[summer cargo]

Probably the same here. Blender prefers Z as up.

I think Fallout may use Y as down which is-- why?

[jagged chasm]

Bethesda just being Bethesda I assume.

[summer cargo]

But i don't have my captures in front of me right now so I can't verify my disappointment.

[brazen oyster]

z is height

positive is up

[summer cargo]

Huh. I wonder why captures are getting it so wrong then...

[jagged chasm]

So are they here?

[brazen oyster]

I think they are right handed though

with z and y swapped

yea

[jagged chasm]

Welp.

Time for some sleep. Then back to the grind of figuring out the pink monster that took over my copy of the game.

[hearty crane]

Robots wont let me in. And a aint gonna fork over 2000 caps. Will try latter.

[dusty pivot]

if you don't care about your save you can do coc topscasino

and teleport straight into the tops

but you'll break every main quest

[short scaffold]

Thanks for telling me that

[hearty crane]

T'was a Joke. Since ets NVSE/Reloaded The save is from TTW(fallout3) so i have alot of caps in that save.
The Inventory is from fallout 3 save 😄
To be clear , TTW is not active. FoNV got messed up for the second time couple od days ago so i installed on other drive. But the saves are the same (cause NVSE i think) as most of ye know.

On a slightly more serious note, someone asked me , if i tried the anti culling.I though he meant remix-anti culling but he said there is a mod for New Vegas for anti culling.Cant find that comment. If anyone knows...

[scarlet pond]

still not much luck on the new vegas front i have most textures sorted but its still really dark and shaking

[hearty crane]

DXVK remix # 75 pasted in trex?

[scarlet pond]

trex?

[hearty crane]

trex folder from Remix

[scarlet pond]

ah ill go check

nope lol

[hearty crane]

DXVK remix # 75 has the option to read the world properly

[scarlet pond]

will that read textures better then

[hearty crane]

This is from the Pined post:
After installing [dxvk-remix-6b4fe7d-75-release]:Game setup->parameter tuning->ShaderSupport->
Use world transforms: DISABLED

[scarlet pond]

having issues assigning lights too

[hearty crane]

I see this aproach in others. You dont need to sort textures , ye need to find couple of them that block the path tracing. Like sun / Cloud , maybe fog...etc etc..

[hearty crane]

We cant assign lights to textures ...yet.
thats why this latest edit( NVR_RTX zip file) from @dusty lynx is a major step , Uses the mod NeVegasReloaded (modified NewVegasReloaded.dll) to add lights that are recognized by remix

[scarlet pond]

Ah

cant seem to find the use world transforms option

[summer cargo]

Ah, but there is a trick we can pull. Finally got this working in PBROven-- the game ignored Add Light to Textures calls, but by using rtx.lightConverter from the conf as a marker for light objects I just marked them all as emissive in a single go.

Not the same game, but the same problem happened here.

[summer cargo]

Parameter Tuning -> Shader Support, I think.

[scarlet pond]

ill give that a try once i fix the world freaking out

is that in game or the config files

[dusty lynx]

I need to give it a better name, there's effectively nothing from NVR inside there anymore

[scarlet pond]

got a link to it?

[hearty crane]

@scarlet pond To be more clear we can add EMISSIVE light to textures but not "add light to textures" .Far as i know Add lights to textures are passing through RTXDI
Ye add emissives in World space UI.

[scarlet pond]

i see

[summer cargo]

Wait World Space UI?

[summer cargo]

That's a Remix menu option.

[scarlet pond]

thanks

been combing files for it

[hearty crane]

Ye. With portals files the sky textures acted as emissives but after v.0.1.1 effectively the worldspace act as emissive.(this is for training purpose/meaning when someone does proper remix the emissives might not be in World space UI , im not saying et should be like this)

[summer cargo]

The sky does have emissive properties from my experience, but if you use World Space UI you're rasterizing the texture. This is a bad idea for textures that include emissive lights and other materials.

[scarlet pond]

Right so it should be where I’ve been tagging stuff but it isn’t

[ornate marlin]

Believe it was me and what I said was people make mods to add more culling so postulated that the opposite should be possible in the geck

Going to ask the Xedit guy if it's possible to auto strip them if they are objects

[hearty crane]

Yes, i Use the sky emissive for the sky, but im refering to geometry textures that you want to make em emissive,at the very least to see where you going (if you inside and everything is dark)😄

[summer cargo]

Yeah so basically I had this issue with Anachronox and marking them as Add Lights then using that as my tag for emissive in the replacements USDA gave me completely playable results.

It won't directly affect the game, but what's important is having this metadata for later. I wish we could assign our own categories of textures directly in the Remix menu, but alas.

[scarlet pond]

Still can’t find that option in the menu

[summer cargo]

It's not in Remix 0.2.0, you have to use one of the absolute latest commits.

[scarlet pond]

Righty

[summer cargo]

I know whichever one consolidated the Remix imgui to three menus includes it.

[dusty lynx]

NV_Mark was saying something like when you pick a UI texture anything else after in the pipe line gets rasterized by default, I'm wondering if world space UI also does this or not

[summer cargo]

But the rtx.lightConverter trick has worked:

[scarlet pond]

Wish GitHub wasn’t such a headache to navigate to find latest versions

[dusty lynx]

how so?

[summer cargo]

The answer is... sometimes. It usually handles other objects better. The problem is you still have a texture that takes in fullbright rasterized lighting. It won't look good at all, even if every other wall is fine.

[hearty crane]

If you add it to UI texture , yes.
But world space UI is acting as emissive.

[scarlet pond]

Idk I’m fairly new to it all

[summer cargo]

More importantly replacements won't work on it.

It is a good workaround but it causes all kinds of headaches, including not being able to capture it effectively until that one commit to capture all materials regardless of rasterization is done.

[ornate marlin]

So just send out an @ to Xedit lead dev honestly their team would probably be able to do a shit ton for RTX remix if they happened to feel so inclined

Linked thread for them

[hearty crane]

no, world space UI is currently Emissives.

[summer cargo]

The real point of World Space UI is to tag UI elements that are confusing the game, like the Kingdom Hearts crosshair-- stuff that takes place in 3D space but isn't meant to take in any kind of light.

[ornate marlin]

Has anyone here looked into Xedit themselves I believe it's all about automated script features

[summer cargo]

To give you a small example of what can go wrong-- in Anachronox, dialogue boxes reflect light in the scene. I tried to turn this to world space UI, but had to disable that as several character models started showing up as rasterized.

[ornate marlin]

And reading game data

[dusty lynx]

so I'm guessing world space ui also does the rasterize the rest of the pipeline issue

[summer cargo]

You're better off just making emissive textures either by hand or in omniverse, or bulk replacing it and fine tuning it later-- I wish there were a better solution.

[dusty lynx]

I'm wondering if that can just be turned off in dxvk-remix

[summer cargo]

Not usually, but without stable hashes weird things can happen, like the Anachronox hud issue.

[dusty lynx]

there's no guarantee that the hud is drawn last in the game

unless that is actually just a bug, it feels like it sometimes I click ignore for a random texture and then half the world falls back to rasterize

[scarlet pond]

this is what i got so far

[hearty crane]

@summer cargo I had this convo with someone else. Might have been adamplayer. Im aware what World space UI is, Marking of enemies, floating prompts over objects and many other things.
Im saying...effectively... as things are now(FOR TESTING PURPOSES,not for proper remix) , consider WorldspaceUI as Emissive

[scarlet pond]

world space is still freaking out

and it only works facing west XD

[summer cargo]

I debated this, but the main reason I'm wary of it even for testing is because it started having weird side effects and rasterizing entirely unrelated objects in a few games (mainly Anachronox and Hitman).

[dusty lynx]

I did get dxvk-remix built so maybe can add in some logging for the game to know why certain things are falling back to rasterized

[scarlet pond]

does anyone have a rtx.conf theyd like to share for comparisons

[hearty crane]

There can be many textures blocking pathtracing, but you have et in the pic.The sun light ye have in there is fallbacklight from remix.

[scarlet pond]

damn i thought id found the sky texture

[hearty crane]

Ye turn in one direction and et might be A NORMAL MAP blocing pathtracing...

[ornate marlin]

https://github.com/TES5Edit/TES5Edit

Yo guess they open source

[hearty crane]

Dont worry i cant find the sky text either. only parts of eth, Clouds.But not to color of the sky

[dusty lynx]

they've always been open source, since 2012

[hearty crane]

Apologies for the slight misunderstanding

[scarlet pond]

maybe i can just add it somehow

gonna go investigate in omnivers

[dusty lynx]

oh I did get the no culling patch from Wall_SoGB integrated, I'll post another build

[hearty crane]

Search for the Sun (small dot with bloom on a dark background) and clouds and stuff like that.

there are multiple

[ornate marlin]

All good, ya people don't typically get rid of culling but should be possible in theory

[scarlet pond]

interesting, importing the usd into blender seems to rotate everything on the x axis

and its massive

[summer cargo]

I haven't used the Blender plugin, but if the same thing is happening in Omniverse you can make the capture a little better with Parameter Tuning by changing Z-up/Y-up and Left-handed/Right-handed.

[hearty crane]

@scarlet pond Ye did that too yesterday,need to extend the view culling to like more than 10kilometers

[scarlet pond]

its also friggin massive

cant even see it

[hearty crane]

@scarlet pond you might even need more than 10km

My scene capture wont open now/cant import.

[simple gazelle]

If your captures are incorrectly sized, make sure you're setting the rtx.SceneScale in the game setup section. And if they're coming in rotated, mess with the zup and right/left handed settings there. (Dunno about opening them in blender, but you should be able to get them to come in right side up and at a reasonable scale in OV)

[hearty crane]

Ingame light from NVR_RTX @dusty lynx.

[jagged chasm]

New Vegas DirectLight?

[hearty crane]

Selected one of cloud textures as UI and now , redness(like yesterday).In conversations et switches to diffrent view/layer?
Btw...i run with alpha blended OFF.

[hearty crane]

Yes in this scene only the light from the left/freeside sign.The rest is emissive (i selected that)from the impersonators sign

[jagged chasm]

The game gets LODs for basically half the map, so it ends up getting massive captures outdoors.

The total map is something like 8.5sqKm

70 game units is one meter.

So rtx.scenescale is 0.7

[hearty crane]

Just emissive from the robot's screen

[jagged chasm]

Any calls that use ui texture gets rasterized as well as any calls after it afaik

[hearty crane]

when Scene unit is lowest , the light from way down the street, reaches to the front gate. 😄
above 30-40 that shadow disappears and gets good occlussion from the sky emissive (tho the sky is at lowest strength here)

[jagged chasm]

Also I should have a template mod.usda that has all the normal textures marked as ignore put together soon.

Oh, light hashes are not stable as BlueAmulet predicted. So I’ll have to figure out how to get them right through the translation between setting them in GECK and how they appear in game.

[jagged chasm]

I think I accidentally set the scale to 70 once and the map was several thousand km long.

[jagged chasm]

So it’d be trivial to just remove all the multibounds to make it so objects no longer cull. I think the difficulty is with getting objects outside of the frustum.

https://geckwiki.com/index.php/Occlusion_Culling

I’m sure @brazen oyster knows where this occurs in the pipeline but I don’t know how easy it’ll be to modify to what we’re looking for.

[brazen oyster]

beware the pipeline

[jagged chasm]

[brazen oyster]

.

[jagged chasm]

I was even there and I forgot :

[short scaffold]

Even this game works better than sim 2

[jagged chasm]

Sims2 doesn’t have this strong of a modding community on the engine part so

[dusty lynx]

sorry was just messing with sun light, haven't made the next build yet with that in

[jagged chasm]

You’re good I completely forgot what happened earlier this morning and pulled a memento

Wall said the sun was unique source, that’s about all I got on it …

[brazen oyster]

btw

https://www.nexusmods.com/newvegas/mods/81251

might be useful

[brazen oyster]

yea it's the only NiDirectionalLight in the game

[hearty crane]

3 lights in this section

[scarlet pond]

how tf you get yours to look not fubar

can you share configs?

[dusty lynx]

perchance is there an easy pointer to this light

[brazen oyster]

ofc

it's in the sun class

there should be a singleton for it too

[brazen oyster]

for sky rather

sky->sun->sunlight

that order

[dusty lynx]

ah okay I see it

[jagged chasm]

Would the Lumen mod do us any benefits?

[dusty lynx]

seems like sun works

[brazen oyster]

more correct light placement

since he attaches lights to meshes

instead of placing them in the worldspace

like Obsidian

[jagged chasm]

I’ll have to try that with the fake lighting remover and see what it looks like

[dusty lynx]

NVSE plugin to pass lighting information to RTX Remix, point lights and sunlight supported

oops I left the old name in the ini, doesn't matter it fills itself in
https://github.com/BlueAmulet/NewVegasRTXHelper/releases/tag/rtx-v0.0.2

[brazen oyster]

upload to nexoos and print money

[jagged chasm]

[dusty lynx]

if you saw the source for this you'd cry

[brazen oyster]

I've seen NVR already

and NVSR

can't be worse

[dusty pivot]

Are you going to share it? Would love to take a peak

[scarlet pond]

still having nightmareish results for this game its still jittering about like mad and it doesnt seem to work

[jagged chasm]

Did you install the latest builds and turn off the world transform?

[scarlet pond]

i think i have but the links to the "latest build just download the same thing

do you have a direct link to it please

[dusty lynx]

you go here https://github.com/NVIDIAGameWorks/dxvk-remix/actions/runs/5029160769

then download the "dxvk-remix-6b4fe7d-75-release" artifact

the contents of that zip get extracted into your .trex folder

[scarlet pond]

thanks

[hearty crane]

3 lights in the next part also

[scarlet pond]

not to sound stupid but where do i download on that page

[hearty crane]

@scarlet pond got to the bottom, The release Zip

[scarlet pond]

thanks

[dusty lynx]

https://github.com/BlueAmulet/TESReloaded10/blob/3f439bae7145f1f264e56f48f987077768a5ee50/TESReloaded/Core/ShadowManager.cpp#L667

[dusty pivot]

Nice one

[hearty crane]

some textures are missing,probably cause the save is from Fallout3.And others,like the grass here,parts of et are phasing in and out of existence.
That sunlight is from the game. 👍 BlueAmulet
(tho the sun texture and the light source are not matched) distant light fixed angle seem the change the angle.

Game lights plus emissive(computer screens)

[jagged chasm]

Here's a file you can add as a sublayer in your own mod.usda to ignore 99% of the normals in game

Interesting, if you take a screenshot in game its completely black when using remix

[lavish isle]

use snippy tool from windows

[dusty lynx]

how do I set up the mod.usda btw?

do I just chuck that into rtx-remix\mods\gameReadyAssets?

[summer cargo]

I was told with Morrowind that this is a gamma issue. Not sure how to fix it.

[jagged chasm]

Oh I do, just thought it was interesting

[jagged chasm]

Yes if it’s already setup.

[dusty lynx]

if?

[jagged chasm]

Typically you have go through the whole workflow of creating the overrides and such but if the mod.usda is setup already with proper values and such you can just drop it in.

You can rename the one I posted to mod.usda and drop it in and it’ll turn off all the normals.

[summer cargo]

I usually recommend using sublayers for ease of use, you can also update the normals mod later and not have to worry about anything else.

[dusty lynx]

how

again I don't know how to set up this mod.usda

[summer cargo]

I'll search, Mark covered it.

But yeah it just needs to be dropped in rtx-remix/mods/gameReadyAssets.

[dusty lynx]

so, it does just go in there, but it also doesn't cause it needs additional setup?

[summer cargo]

i.e. if mod.usda is this:

#usda 1.0
(
    subLayers = [
        @./mod2.usda@,
        @./mod1.usda@
    ]
)

then it will load mod1, then apply mod2 on top of it

Copied and pasted from the legendary nv_mark.

That could be your entire mod.usda and if you have the name of the normals mod instead of mod1 it'll work.

mod.usda is just kind of hard coded to read that spot but sublayers are very flexible.

[dusty lynx]

alright, thanks

[summer cargo]

Yeah it's kind of unintuitive at first but I have a couple ideas for improving it when I have more time to investigate.

[jagged chasm]

I wonder if we can get hot swappable texture packs using mod.usda.

Cause we can get the hashes for all the given textures, then make their mat_hash entry, and then using the name of the texture to match it up with the replacement.

[dusty lynx]

I wish there was a reload rtx.conf button

[dusk rock]

i'm gonna submit a feature request for that

[dusty lynx]

I added it myself

[dusk rock]

ah

glad i didn't submit it then

[dusty lynx]

though seems like I need to trigger reset first

[dusty lynx]

I submitted a request for it anyway, since there's some "base game modding system" thing that also has rtx.conf files that I don't fully understand and left out in my commit
Here's a build though: https://github.com/BlueAmulet/dxvk-remix/actions/runs/5063069649

@jagged chasm btw might be a slight issue, I'm noticing that hashes in rtx.conf don't retain their leading zeros

[jagged chasm]

Yea i noticed that too. I’ll update my script to add them back later tonight

[dusty lynx]

add them back? I meant that the script needs to be updated to remove them as well

oh huh, captures do have leading zeros, it's only the rtx.conf that doesn't

[jagged chasm]

Bulk adding hashes to the rtxconf causes problems. Would not suggest going that route.

It causes a buffer issue with parsing the file on startup.

[jagged chasm]

I don’t remember if the material hashes have the padding left on, but that’s where I’m focused on automating.

[simple gazelle]

Have you filed a github issue for that? cause that should be fixable

[jagged chasm]

Just discovered yesterday, so not yet.

[simple gazelle]

Please do when you have a chance - including info about what the actual problems are

[jagged chasm]

Issue: “Adding 23,000 entries to rtx.ignoretextures causes the whole thing to fall apart” it also breaks vscode since it’s on one line.

[jagged chasm]

For you mark, anything

[summer cargo]

Hotswappable, not 100% sure. Only mod.usda hotswaps, and that actually causes a bit of instability from my experience. But I do want to write a launcher, it's been on my to-do list since before even my current project.

It would be really easy to get a list of all *.usdas in the rtx-remix/mods directory and write a really basic subLayers file in mod.usda before startup.

Not to mention it would be a place to include commands per-game.

[jagged chasm]

So the mod.usda gets read anytime it’s written to. So if you have a mod usda that has a different set of textures set as the diffuses it should in theory load the new textures.

[summer cargo]

Or so I thought, but apparently it doesn't care much about sublayers.

Now, if you wanted to use an external program to treat your mod.usda as a gathering place for all your mods, that could work.

...you know what? Let's prototype it. 🤣

[jagged chasm]

It’s triggered by the mod usda file, so modifying that is essential.

But maybe a main mod usda with only subs.

Use that to select the options

[summer cargo]

Maybe, I guess we'll just have to see what happens at runtime.

So I guess this is an excuse to prototype the launcher now. I know @fresh belfry is working on something really cool but I may do this in Unity for convenience.

[jagged chasm]

I can write it in Python

[summer cargo]

godot it is then. 😂

I'm gonna hop into streaming if we want to get this started right now.

A mod loader was on my to do list anyway for RF2.

[jagged chasm]

I could ask ChatGPT to write in something bizarre

[summer cargo]

Unity would be really overkill for a launcher, but GODOT is completely unfamiliar territory to me so I would need a lot of guidance.

[jagged chasm]

VB.net

[summer cargo]

Nah, darkbasic only.

[simple gazelle]

We're planning to add that within the remix UI... eventually. just list the files in rtx.conf and make a basic imgui for adding, removing, and reordering them

and a button to trigger reload

[summer cargo]

Oh nice.

[simple gazelle]

no need to do it in a launcher

[summer cargo]

Well this would be more of a replacement for games that already have a launcher, like Red Faction II.

Basically an easy way to provide access to options that make sense for the game.

And of course remove options that don't, like texture quality or shader quality.

[simple gazelle]

ah. Yeah, having a more user friendly settings menu per-game makes sense - especially since someone with a low end card may have really poor frame rates on a 4090's config

[summer cargo]

I didn't even think of that but yeah, allowing some basic rtx.conf tweaks for presets would be great.

Mark, stop being awesome, we can't keep up

[simple gazelle]

just to be clear, we're not planning to build any form of launcher like that ourselves as far as I know

[summer cargo]

Yeah I get ya, that said the functionality within imgui would be more than enough.

The specific reason why I originally wanted to do this was because I was still working on RF2 at the time and wanted to get past the launcher in that game, which is actually kind of cluttered and missing tons of useful options.

So to cover some basic functionality in Remix and take down that in one fell swoop made sense, it's just that now that I have more projects I'm on board with it would probably make sense to have the launcher be a little more generic/flexible? Anyway I think I need to just prototype it instead of promising the moon here. 😛

[simple gazelle]

It may also make some sense to think about how all of this integrates with mod managers.

[keen niche]

In theory, MO2 could be forked to work with the RTX files.
I believe it recently gained the ability to work with mods that require things in the main game folder instead of just the data folder, so it wouldn't be a stretch.

Actually, it might already work? I'm not sure how that functionality is implemented, but maybe it already can access other subfolders of the main?

[jagged chasm]

I haven't gotten any scope creep out of automating the whole texture replacement workflow

Anyone interested in seeing some workflow of integrating some of the game's non diffuse textures? I can hop on stream

[summer cargo]

Let's see them textures.

[keen niche]

I am curious to know how you might get Remix to recognize the game's normal and emissive maps.

Or convert them so Remix can use them?

I wonder if that's something RTX Remix could do on its own at some point? It's able to read and see the textures, but it just seems to treat them as diffuse.

[simple gazelle]

I imagine that if we get actual FFP games to the point where we're satisfied, adding some way to configure, tag or otherwise use more textures from the game would be a low hanging fruit. We're probably not going to be putting much work for a long while, but you could always dive into the code and figure out a way to do that yourself 😛

The problem is that for shader based games, the API doesn't get any info about what a given texture is for - only that the game is passing these 3 textures and a block of bytes to the shader, which the shader knows how to read.

[keen niche]

I don't suppose Remix gets the name of the texture, does it? Just a hash?

[simple gazelle]

nope, just a series of bytes. We generate the hash ourself

[keen niche]

Darn.

Although, the hashing algorithm you use would be public, right?

And I would hope that it would be based off the actual texture data, and consistent if you run it on the same one over and over?

[simple gazelle]

You could probably make something in the Remix settings, like "this game passes the normal first, then the diffuse..." and then adapt our legacy material code to handle the incoming textures based on those settings

[keen niche]

Ooo, that's a way to do it. Of course, if it can remain consistent.

[simple gazelle]

yep, fully publilc, and someone (I think anchorlight?) has a python script that lets him generate matching hashes from the .dds file. He basically just has the strip the header and hash the rest

[keen niche]

Otherwise, I'd think that, if your hash algorithm is consistent with texture data, then you could externally extract and process the game's textures-

Oh dang, that's exactly what I was thinking!

[summer cargo]

Not me, I think it was AdamPlayer or BlueAmulet.

I have a script that does the same thing but only for the sake of converting to Unity Texture2Ds.

[simple gazelle]

#1110438207050485771 message

Both of them together, apparently

[keen niche]

Externally run the hash algorithm, generate the RTX thing, and assign it based on the texture's suffix. In NV's case, they all have the main name with _n, or _g.

[simple gazelle]

yep.

We haven't put that much emphasis on handling the original game's textures, since ideally all of them will be replaced with remastered PBR materials anyways.

[keen niche]

True, but if that AI enhancement thing is still planned, having the full array of original textures to base it off could help get things started.

[summer cargo]

I think most of Remix was also geared for games that weren't released after the year 2010 with normal maps and shaders. 😛

[dusty lynx]

Since that doesn't explicitly say it, it's a XXH3_64 hash of the first mipmap

@jagged chasm would you happen to have a mapping of hashes to bsa filenames?

[jagged chasm]

No not yet. That'll be done sometime soon though

[dusty lynx]

alright, just trying to investigate what certain broken textures actually are

mainly the ones that force alpha blending off or else a weird dome covers the view

[keen niche]

The only dome I know of is the sky dome. Or maybe fake lighting objects?

[hearty crane]

That dome might be fog...not sure

[keen niche]

Oh, fog is done in the object shaders, per-vertex.

[jagged chasm]

It'll just be a simple modification to output the name of the file before it gets hashed.

[jagged chasm]

It's a dust texture. It'll need to be mod.usda'd out.

[summer cargo]

I noticed that geometry hashes can now be added to the conf as skybox hashes.

So... whatever physical dome this is, could it be ignored this way?

[keen niche]

And then if there's some way to automatically convert normals and stuff to whatever format Remix uses, it could be done based on the filename if it follows a consistent naming scheme.

[summer cargo]

ChaiNNer can handle that very easily.

[dusty lynx]

yeah unfortunately unless a mod that changes the world moves around camera to camera moves in world, mesh hashes won't be stable

[summer cargo]

We just need the normals in a folder on their own, and we can use Convert Normals DirectX to Octahedral assuming it's the right format.

[keen niche]

Could just use BSA Browser and extract all _n.dds files from the texture archives.
Can even tell it to put them all in the same folder rather than preserve the folder structure, if needed.

[dusty lynx]

also that culling patch doesn't seem to actually be working, I confirmed in x64dbg that the call did get changed, but still seeing frustum culling in the captures and obvious light leaks

[keen niche]

@ wall?

[dusty lynx]

soon, going to do a couple more basic checks on it first

[jagged chasm]

If we say his name three times into a mirror he'll appear

[hearty crane]

This one?

[keen niche]

Ah right, the game also uses the alpha channel of normals for... specular, I think. Or an envmap mask, which is basically reflectiveness.

[keen niche]

I extracted all the normals to their own folder, and there are 3,411 of them.
In just the base game, not counting DLCs.

[hearty crane]

Better pic.Alpha blended is on

[keen niche]

Counting the DLCs, we've got ~4,024 normal maps.

[dusty lynx]

went ahead and made the list, some are sky textures as expected, but confusingly some are also landscape lod textures?

[keen niche]

Maybe Remix doesn't like extremely far-away textures?

[dusty lynx]

also I have no idea what the direction values in the directional light are supposed to represent, so I'm just going to do the same thing that shader manager does and use the sun's local position during day time

[keen niche]

Ah yeah, the game's really weird with its sunlight direction.
I don't know the specifics, but even in the base game, the direction objects get lit by is inconsistent with the actual sun sprite in the sky.

[jagged chasm]

Yes I've had that happen before. It's weird

It's like the 128x128 texture for the cells on the other side of the map

I think remix really doesn't like how big the map is with fallout

[dusty lynx]

unless it's something stupid like, texture being bound but ignored by shader

that's probably what it is.

@simple gazelle idea, if dxvk already has the ability to parse shaders, is it possible to have remix parse through a shader and look at what texture slots are actually used

Here's one of the calls from New Vegas that draws the sky, the pixel shader itself uses no textures, but you can see it has a bunch of miscellaneous textures bound to it

[keen niche]

Huh, I wonder if that's due to the game's behaviour with missing textures?
It just kinda... randomly assigns whatever's in memory.

[dusty lynx]

also I just realized since that mesh is always directly over the camera it might be one of the few things to have a stable hash

[keen niche]

What about going between worldspaces, or in and out of an interior?

[simple gazelle]

I don't know much about DXVK's shader handling, but my understanding is that it translates it to vulkan without every actually understanding what the different inputs are.

like it knows that the pixel is made by combining inputs 1, 2, and 3 to form a uv coordinate, sampling textures 1 and 2 with that coordinate, combining them using some math, then outputs a color. So it rewrites that in Vulkan, without every identifying any of those inputs or textures logically

[dusty lynx]

All it'd need to do is just go through the shader and make a set containing all samplers used by it

[simple gazelle]

What are you trying to do? For remix to use those textures at all well, we need to figure out which one is which.

[ashen bolt]

Cloud texture, DXT5 with alpha layer

[dusty lynx]

the shader that draws the initial sky doesn't actually use any textures, but the game still has a bunch of random textures bound, remix associates one of the unused textures with the draw, even though it's actually untextured

causing oddities like the skybox dome being associated with random lod landscape textures

[ashen bolt]

In game the "sky" is a dome mesh with various layers for color (top) and clouds (3 layers with a diffuse texture for each). It can also be used without texture or only with one, two etc, depend how the weather is set

[ashen bolt]

Alpha layer in a normal map texture is the specular texture.

[jagged chasm]

I’m learning so much

[jagged chasm]

Did you test this theory? I’m under the same impression now since it’s always in the same place.

[dusty lynx]

I don't have anything omniverse atm so having to setup some python stuff to convert the usdc to usda, blender for whatever reason doesn't load the mesh names

should be mesh_FD3E0F698346CFFB though

hmm, only one of my captures has that

oh nvm, do have to fully convert it to text, yeah it's probably stable

[summer cargo]

It sounds like mesh hashes aren't stable enough to rely on right now.

[dusty lynx]

right I forgot there wasn't just one dome

[ashen bolt]

ONly one mesh but with multiple textures

[dusty lynx]

there's definitely more than just one mesh

[ashen bolt]

there's also the sun, the moon

[dusty lynx]

there's like two half domes, a weird full dome, and a small sphere around the player

[ashen bolt]

It's the same asset

[dusty lynx]

as in one .nif with sub meshes then?

[ashen bolt]

Ah nah I forgot the atmosphere nif

[jagged chasm]

Current Status update for the lurkers:

[ashen bolt]

Ah and sorry I also forgot the .. stars mesh 😅

The "clouds" mesh is like that :

[dusty lynx]

ah yeah that's what I see too, though minus the full dome

[ashen bolt]

with 4 nitrisrips
CloudDome
HorizonLayerClear
HorizonLayerOvercast
LowerLayer

[dusty lynx]

what .nif is that?

[ashen bolt]

it's in data/meshes/sky/clouds.nif

[fresh belfry]

https://tenor.com/view/do-it-get-to-work-gif-21630516

[fresh belfry]

do eeeeiiiit 😤
We can be launcher making buddies 😂

[fresh belfry]

[Feigns horror]
oh nooooo, another excuse to keep working on my project, whatever shall I do?

[dusty lynx]

hashes seem stable:

mesh_3D3D8C9293791DA7 # CloudDome
mesh_41196276600FC6DE # AtmosphereDome
mesh_41C4B5862B73847F # LowerLayer
mesh_D513E037BD073799 # HorizonLayerClear
mesh_9119325A4E3BFC1E # HorizonLayerOvercast
mesh_FD3E0F698346CFFB # Stars

also kind of just find this funny but this sphere is the Stars mesh

[ashen bolt]

https://tenor.com/view/death-star-spin-star-wars-loop-death-star-plans-gif-20589431

[fresh belfry]

We have Mysterio at home:

[dusty lynx]

damn, only the atmosphere dome is being unstable, the rest seem fine

[keen niche]

The mesh hashes don't change if the textures do, right?

[dusty lynx]

don't think so, but also can't target that mesh since that's the untextured (gets wrong random texture) one it seems

so just replaced it with an empty nif

oh nice, just removing the atmosphere mesh and then getting the rest of the sky textures actually marked as sky works pretty well

[keen niche]

Okay, I've managed to seemingly get Remix loading in to the game, but I don't see any changes aside from major performance loss.
I also can't find these 'Experimental Shader Support' options, which I assume is a big thing I'm missing to make this functional.

I installed your latest thing, Blue, with the sun, and your hack for the multithreading.

Am I missing a newer Remix build or something?

[dusty lynx]

Did you also get the nightly dxvk-remix build?

[keen niche]

Ah, no, but I did just install it.

However, annoying thing, I can't see my mouse cursor in the Remix menu.
I can still use it, but it's all guesswork until I actually get a tooltip to pop up or something.

[keen niche]

Okay, maybe I didn't, since I still can't find the option.

[dusty lynx]

that second screenshot looks like you're still under the Rendering tab, switch to the Game Setup tab

you should also be able to do it by just putting "rtx.useWorldMatricesForShaders = False" in the rtx.conf

[keen niche]

Gosh, this invisible mouse thing is really making this hard. I can hardly navigate, especially when tabbing in and out.

[dusty lynx]

Unsure what would be doing that, if it's cause of fullscreen or some other mod like onetweak

[keen niche]

I'm in a fullscreen window, and don't have OneTweak installed.

[dusty lynx]

though I think there's also an rtx.conf option to force the cursor visible, lemme look for it

#1055003495637454879 message

but yeah, try hitting alt-del (might be specifically numpad del) while the remix menu's open, or add rtx.showUICursor = True to rtx.conf

[keen niche]

Okay, now we're getting somewhere!

...Still looks the same. Do I need to change something? Toggling those shader options doesn't seem to do anything.

[dusty lynx]

that isn't the nightly dxvk-remix build, mainly cause all those various steps of texture options got merged into one on that build

https://github.com/NVIDIAGameWorks/dxvk-remix/suites/13024815441/artifacts/705576471

unpack that zip into the .trex folder

[keen niche]

Really? These in to that folder?

Oh dang. 😨

I've just been putting it directly in to the root.

[dusty lynx]

the d3d9.dll the root gets is just a dummy dll that passes along info to a 32bit to 64bit bridge, all the stuff inside of .trex is 64bit dlls

if you had a 64bit game, then in that case you'd actually use all the .trex files instead in the root, but uh, new vegas old.

[keen niche]

Woah, okay. I thought the game was just a black screen, but that's only because it's dark!
I turned my Pip-Boy light on, and there's a rock's normalmap glowing at me!

Huh, it looks like the normals are only glowing like this when a point light comes in to range.

Oh my gosh the sun sprite is huge and in front of everything!

[dusty lynx]

here's a fairly minimal rtx remix setup, some sky and ui textures marked, and normal maps ignored (unpack to root folder)

and the atmosphere nif patch (install in mod manager)

[brazen oyster]

I see that my culling patch is not working

I suppose the cull mode is changing afterwards then

imo then it's best to replace Process functions to just run OnVisible without any checks

let me launch IDA

brb

[dusty lynx]

yeah, I verified the call gets changed, that it is being called, and have an offsetof(kCullMode) == 0x90 check

[brazen oyster]

though that would disable culling for any culling process

unless I check the culler beforehand

yea

that could work

[keen niche]

It's okay, the local map doesn't work anyway.

https://cdn.discordapp.com/emojis/494877677660930048.webp?size=96&quality=lossless

The Pip-Boy background is interesting, though.
Since it renders a still image and uses that instead of actually rendering the scene continuously, Remix can't deal with it.

[brazen oyster]

yea it's the same issue as NVR

[keen niche]

And then the Pip-Boy itself looks oddly perfect... I wonder if Remix isn't picking that up, either?

[brazen oyster]

remix would have to save data onto the render target

and then present

[dusty lynx]

that's definitely falling back to just plain rasterizing

[brazen oyster]

yea

it's because the game simply copies the last frame for the background

and the data from Remix, logically, is not saved onto that frame

[dusty lynx]

lemme get one of my cursed pip-boy

[keen niche]

But then what about the actual Pip-Boy? That's still a 3D thing.

Maybe it's in a different scene or something...?

[brazen oyster]

looks like the shader runs properly (there's a cut out)

but it's downscaled?

[keen niche]

Cutout?

[keen niche]

Isn't that just the black screen of the Pip-Boy itself?

[brazen oyster]

if it were a raw RT, you wouldn't see this

[keen niche]

Looks like the menu's using world FOV instead of view FOV.

[dusty lynx]

in Game Setup -> Parameter Tuning -> View Model, there's stuff for trying to fuse world and view

which doesn't seem to affect the pip-boy at all, but having it on fixes the hands

[keen niche]

I found that, it made the first-person hands and weapon use the correct FOV.

[keen niche]

Do I just stuff these in the .trex folder?

Not the meshes, but the rtx-remix/mods and stuff?

[dusty lynx]

that goes to root folder

[keen niche]

I don't know why that guide says not to use Mod Organizer with this, it seems to work fine.

[dusty lynx]

which one? I'm using mod organizer atm, it's been working fine for me

[keen niche]

The pinned one here.

[dusty lynx]

though I don't use that funky root folder manager plugin someone made

[keen niche]

Okay, this looks like an improvement.

[dusty lynx]

weirdly seems like the rtx-remix\mods didn't get loaded, should be like: Fallout New Vegas\rtx-remix\mods\mod.usda

oh, unless those are custom normals

[keen niche]

Ah, I put it in the .trex folder alongside rtx.conf.

[dusty lynx]

bruh

[keen niche]

😅

[dusty lynx]

I put "(unpack to root folder)" on the initial message, and said to you after "that goes to root folder"

[keen niche]

Okay, yeah, that seems a bit closer now that it's actually loading that mod.

[dusty lynx]

yeah, so sadly making it ignore normals doesn't actually fix the textures, but it's less obnoxious than seeing the normals I suppose

[keen niche]

Those clouds up there might be a custom texture. Or is that looks kinda expected right now?

[dusty lynx]

I'm trying to see if I can patch dxvk-remix to handle that better, but I cannot find where LegacyMaterialData is constructed

uhh, yeah might be a custom texture, I added all the vanilla sky hashes to the rtx.conf

[brazen oyster]

@dusty lynx based on the immense FPS drop I assume it's working

    void __fastcall BSCullingProcess_ProcessEx(BSCullingProcess* apThis, void*, NiAVObject* apObject) {
        apObject->OnVisible(apThis);
    }

SafeWrite32(0x101E330, (UInt32)BSCullingProcess_ProcessEx);

[keen niche]

Ooo, I fixed the trees! 🥳

Eyy, found the sky!

Oof, it can't do texture blending at all, can it?
That'll be a problem since... the terrain 100% relies on it.

[dusty lynx]

terrain blending system is in the works I believe

[keen niche]

This is also weird and interesting:

[keen niche]

Ooo, I see.

[brazen oyster]

do coobemaps work?

[keen niche]

Dunno, but probably not. Shaders basically aren't running, so it won't be visible. 😔

I did turn it off prior to this, just in case.

[brazen oyster]

what about water

[brazen oyster]

lmao

[keen niche]

https://cdn.discordapp.com/emojis/494877677660930048.webp?size=96&quality=lossless

I mean, if this all works out, then it won't be needed, since the rays will do the reflections for us, for basically free.

[brazen oyster]

I'm just curious how it looks

[dusty lynx]

this somehow made the entire game black, and I tried to blindly coc to a location and the game crashed lol

[brazen oyster]

works here, drops to 10 fps

[keen niche]

RTX Remix might be able to handle it, depending on if it can detect where those textures come from.
However, since water seems to be made of multiple overlapping noise textures distorting the image, and then colored by the game's water settings...

[brazen oyster]

also

this means the water is rendering still

disable it lmao

wasting perf

[keen niche]

Ah, I should do that.

Isn't that in your plugin?

[brazen oyster]

yea

[keen niche]

Where is that, again?

[brazen oyster]

I wonder if my renderer works

[brazen oyster]

here

enable fixes in the ini

[keen niche]

True Scopes doesn't seem to do anything, but that might just be because Remix can't deal with the texture, especially because it updates and changes every frame so the hash will never be stable, unless maybe it can use the camera plane's geometry?

[brazen oyster]

if you want a version with culling working

[dusty lynx]

hmm still getting black screen with remix disabled, wondered if some other patch in that is needed, assuming that's nvr?

[brazen oyster]

does this one work?

[keen niche]

I installed it and my game didn't crash.

@brazen oyster Where's the config to turn off water? Or do I just use the ini setting which actually works with it installed?

[brazen oyster]

mws reflect

in console

or

[Water]
bUseWaterReflections=0

[dusty lynx]

oh that template one definitely works, framerate tanked

[brazen oyster]

insanely based

[keen niche]

How do I know if that sun thing or the lights are working from that RTX Light plugin?

[brazen oyster]

Demaster the renderer
Disable all optimizations
Buy a $4000000000 GPU
Break every shader
Yup, RTX time

[dusty lynx]

do any of the lights from the original game exist in remix?

[keen niche]

https://cdn.discordapp.com/emojis/860244419151528016.webp?size=96&quality=lossless

[keen niche]

Not certain how to figure that out. I guess just... go somewhere with lights?
The Pip-Boy light doesn't seem to work, at least.

And I don't see any particular sun shadows, but maybe they're drowned out by the white sky.

[dusty lynx]

if the pip-boy light works then it's probably working, but yeah just go somewhere with lights essentially

[opal crystal]

Looks like a circus.

A really weird circus.

[keen niche]

Mmm. I guess the lights are at least sort-of working.

[brazen oyster]

nice fog

[keen niche]

I think that's from the light beams?

Unless it's somehow detecting multibounds or trigger boxes, or something?

Hey, the lights respond to scripting properly!

I don't see the Pip-Boy light, and my gun's a ghost, but that shadow's cool!

Okay... I'm not sure why that changes things, but making the breath meter a UI texture fixes my gun's texture!

Not sure what's going on with this, though... this cell doesn't normally have a sky, just black void.

It also follows my camera, which is weird.

Ah, I don't think the anti-culler really worked.

[brazen oyster]

ohh

lights have their own culler it seems

[keen niche]

Wait, no... that's the outside light leaking in, I think, because there are no white lights, and it turns black when I look towards the supposed source.

Unless... maybe it's happening because there are roombounds in this cell?

[brazen oyster]

but it's disabled

[dusty lynx]

yeah it doesn't seem to be not culling, framerate's worse but

[brazen oyster]

tf is it doing then

inb4 it's based on player rotation or some shit

instead of the frustum

[dusty lynx]

it seems to have made several duplicates of everything

[brazen oyster]

fuck it I'll override SetCullMode

to ALL_PASS

[brazen oyster]

[keen niche]

https://cdn.discordapp.com/emojis/860244419151528016.webp?size=96&quality=lossless

Also, this looks really cool.

[brazen oyster]

aww, crashes

[keen niche]

I see... that's probably not actually Remix's intentional doing, but a ghost of some weird frame.

Finally found that white layer on the gun!

Wait... if it was culling things behind you, how would this shadow work?

[keen niche]

Okay but why though?

That's... interesting. The scene changes color when True Scopes would be active.

[brazen oyster]

does this one work?

[dusty lynx]

Going to sleep so can't really test

[brazen oyster]

sleep well then

[dusty pivot]

NVR has code to identify the constant table. Actually most constant are named in compiled code and can be identified

[keen niche]

Man, Remix uses so much CPU.

[dusty pivot]

(Not Responding)

[hearty crane]

NCR Embassy has the most light for a interior. 7 lights.
Also this is a try with lumen mod but still total lights is 8.The mod uses a separate shader so...

Shadows are dark so you can see the direct lighting only/indirect is off

[keen niche]

Indirect looks fine here. Shadows aren't too dark.

Or maybe it looks okay because of multiple lights in different places?

RTX really shines on small details like this.

[brazen oyster]

you want to see the largest light count in the game?

go to vault 21

[keen niche]

The casino vault. 😨

Oh, what's the COC code for that?

[brazen oyster]

you have over 10 lights per mesh there

it runs like utter shit

[brazen oyster]

search vault21 in console

[keen niche]

Woah, immediate 60fps upon entering the vault proper.
