Call of Duty 2

[spring lantern]

Yeah I would try the original COD 1st

[timid trout]

It is an OpenGL title.

I tried with wrappers but it does not even work without remix runtime

[spring lantern]

I've just installed COD4 original on PC. going to try that next

[timid trout]

The most glitchless shot I could take

Normally looks like this

Dependent on the direction you look at

[harsh marten]

So it works now with remix 0.2.0 without additional setup?

Will try this out today if I can and work on the tutorial with usds

[chrome onyx]

remix 0.2 semi works on cod waw now, did anyone check cod 4 with remix? I want to see if cod 4 also semi works

[chrome onyx]

how did you get cod2 to load with it? I only get the menu to load

[timid trout]

Yes, just set the renderer to dx7

[timid trout]

Renderer must be dx7

No need for a wrapper since the game still uses dx9 but disables certain features

[chrome onyx]

how do I force the render to dx7 on the cod engine?

[timid trout]

launch the game without remix, set the renderer from auto to dx7

in the settings

[chrome onyx]

thanks

[dull oar]

Aren't those decals with messed up depth sorting? Maybe trouble with alpha textures?

[chrome onyx]

On the Singleplayer exe, walls floors and the first person hands and gun are all see through

[sour terrace]

I got this reply on github if anyone wants to try it

[timid trout]

Can you link the issue?

[sour terrace]

https://github.com/NVIDIAGameWorks/rtx-remix/issues/150

[dull oar]

had some luck with rtx.skipDrawCallsPostRTXInjection = True in rtx config

[timid trout]

Wow

[dull oar]

managed to replace some textures now 🙂

guys this is so much fun already! slimy mud anyone?

[harsh marten]

Using Adobe to replace the .dds files?

[dull oar]

Yea, just playing around really.

[harsh marten]

Looks pretty good. Will give it another go today, and will try adding some lighting to the environment.

[dull oar]

Having trouble trying to get a sun in the game. Not much in the way of omniverse tutorials out there for rtx remix

When you tag textures mark the big white one at the top of the list as UI to get it to render with rtx. Untag it to see in game UI but you loose rtx.

[harsh marten]

Yeah I have the same issue with other games I'm testing. Sometimes the game has multiple textures/models which handles the skybox. So you have to try capturing at different times if the game has a dynamic skybox. Then check if the hash code the the skybox lighting and skybox is changing

[harsh marten]

Sorry what do you mean by Tag a texture? Is it the in game rtx-remix option to mark as UI and those sort of stuff?

[dull oar]

Yea when you select what's UI textures

[harsh marten]

Ah okay

Have you tried adding lighting in omniverse and see it in game?

[dull oar]

I managed to get a sphere light in game attached to a mesh but beyond that no.

[harsh marten]

Oh okay. That's pretty good

[dull oar]

Don't forget to add this to rtx config rtx.skipDrawCallsPostRTXInjection = True

Never once crashed or froze, plays really well

[harsh marten]

Hmm... What do you see if that setting is false?

[dull oar]

This depth sorting mess

[harsh marten]

Ah okay

Thanks for the info. Will give it a go later today.

[chrome onyx]

since there is no other channel for the other cod games, I'll just post it here. Cod 4 and WaW have a command that can force the shader model down to 2.0 . WaW will only display black and nothing else when doing so.

r_rendererpreference

[dull oar]

ok got it sorted, mixture of marking base textures as terrain and marking decals as dynamic decals and waiting 5 seconds for the change to happen. (that bit got me :P)

[dull oar]

https://youtu.be/kRfhVGFSk7c

[sour terrace]

Would you be able to share your rtx.conf?

I want to try out dawnville

[dull oar]

only tried Carentan so far, just a heads up to see the UI you have to mark that white square as UI but you'll loose all RTX features

wow it works

need to tag new stuff as terrain and dynamic decals again cause you get map holes

[slate plank]

Have you tried enabling Anti-culling? It should help with the culling artifacts (shadows due to objects behind the camera disappearing) in the video. Note, you will want to use a recent build which has some improvements added for the feature.

[dull oar]

Oh yep had a go but it's not working well on .2 and I'd need help compiling the latest. Artist not a coder I'm afraid.

you've filled up my memory all the way to the top 😛

if i'm paying for a GPU i'm going to use the whole GPU 😄

[slate plank]

Thanks for the feedback, we'll look into the VRAM overusage!

[timid trout]

Is this the config you are using? mine looks quite different

What patch are you guys running the game at

[dull oar]

just whatever's on steam, can i get a screenshot please?

[timid trout]

Some of the textures marked as terraing are walls

I am on 1.0, 1.3 patch breaks remix for me

[dull oar]

Yea on 0.2 walls needed to be marked as terrain but on latest you need to turn off all textures marked as terrain and all decals that go over terrain like grass, mud ect need to be marked as dynamic decal based on my test this morning. Terrain should only be the base floor textures so for example the cobble bricks. I'll upload a new config tonight if you like

[slate plank]

The terrain system in the recent builds should handle horizontal terrain (some slopes that aren't too vertical are OK as well) and any aligned layers that are to be blended over it: mud, snow, flat grass (not grass blades). Can you show me a scene where it doesn't work according to the expectation?

Note, if terrain in a game doesn't consist of multiple blended layers, don't tag those textures as terrain. It's always preferred to render those as regular surfaces. The terrain system is there to resolve the blending of multiple layers. For example, you could have a terrain consisting of mud, grass and dirt being blended but the cobblestone is not blended with anything, then you'd only tag the textures that blend over another, but not the cobblestone.

[dull oar]

yea so the only way to get the decals to blend correctly over a model like in the case of buildings yesterday was to make those textures as terrain and the decals over top as dynamic decals and they would work together. after updating to your build yesterday (thank you btw for that peter) if i unmark those buildings and mark decals as dynamic decals it works again. only things i marked as terrain are the additive layers of textures over the base ground and cobble stones. looks awesome again 🙂

ok no more spam
latest rtx.conf 🙂

[slate plank]

That's looking rad!

[dull oar]

mod for pushing back LOD distance with a LOD bias (value -1000). just download the dll and rename it to "gfx_d3d_mp_x86_s.dll"
https://www.moddb.com/downloads/call-of-duty-2-single-player-improvement

[sour terrace]

you can also use r_forcelod 0 to use only the high quality lod

[dull oar]

cant get it to work in multiplayer, anti cheat doesn't let you set it

[sour terrace]

ah
didn't realize that

[dull oar]

slowly working my way through these texture replacements. trying to get the normal maps to really pop

for comparison

[timid trout]

I thought the first image was the original. I was saying: Oh, did this game look that good at the time?

[dull oar]

Only in our imagination

If I had a sky texture I could swap that and really make it shine

Can't find anything related to the sky in any capture. Might be a camera effect? Any one else ever seen a sky box or dome in a usd capture?

[sour terrace]

Is anyone else having issues with resolution?
It's limited to 1440x900 for me even though I have a 1920x1080 monitor

[dull oar]

seta r_mode "1920x1200"
pop that into your config file found here 🙂 D:\SteamLibrary\steamapps\common\Call of Duty 2\main\players\USERNAME

[lapis bear]

it's crazy to me how much more exciting this is that any new release I can think of

[dull oar]

cant wait to work the assault on Normandy beach in single player, that oceans and cliff face going to look so good with path traced reflections.

[timid trout]

How it is going with the latest dxvk-update? The extreme culling in the NFS Underground 2 seems to be fixed.

Nevermind it is related to lights :/

[dull oar]

yea the lights look better but meshes are still coming and going as the camera moves. less artifacting that last weeks build with anti mesh culling on so we're going in the right direction i think.

[dull oar]

Hey guys, could someone please add "rtx.geometryGenerationHashRuleString = positions, indices, geometrydescriptor" to their rtx.config and go to debug, debug view and switch to geometry hash and tell me if everything still flashes multiple colours?

[timid trout]

Yep

[dull oar]

Ah brilliant cheers Kamilkampfwagen. Well that's no good, should ideally be stable without the flashing

It's not been a problem so far, I've added lights and meshes via create and it's all been stable. The mesh I replaced doesn't flash anymore either. Maybe we'll be ok?

[radiant belfry]

try removing indicies or positions

this is the list to pick from: positions,indices,texcoords,geometrydescriptor,vertexlayout,vertexshader

[dull oar]

Something to note character is stable and so are trees

[radiant belfry]

i only have the cod 2 demo unfortunately

i don't know if that works with remix. guess it's worth a shot. might be able to help

[dull oar]

If you do give it a go you need to change the renderer to DX 7 in graphics settings, you'll be good to go from there

[timid trout]

Removing "positions" causes game to freeze at menu -at least for me-, removing "indices" does not fix the problem

[radiant belfry]

you guys are on the remix build from today?

[timid trout]

err: Exception on CS thread!
err: Position hash should never be empty

on CoD2MP_s_d3d9.log

[timid trout]

Oh let me update

What is that

[radiant belfry]

no idea

i don't have that

[timid trout]

Same isssue except it is all black now

[radiant belfry]

i have extremely unstable visuals

[timid trout]

I will try with the previous bridge build since it also break BF1942

Oh wait

this is not related to remix update

It is because I quit with taskkill

lol

[radiant belfry]

warning, flashing

[timid trout]

War is hell, what you expect

[dull oar]

Try adding rtx.skipDrawCallsPostRTXInjection = True in rtx config Kim, it gets rid of the see through stuff

[radiant belfry]

lol

[dull oar]

Floor textures get fixed if you make them as terrain

I'm going to have to go out for a couple hours

[radiant belfry]

i think the demo is less stable than the full game

i can't really do much of anything with this

[dull oar]

Thanks for taking a look mate

I won't give it a go unless this mesh hash starts giving me trouble. So far everything is working great though so I'm going to plow forward. Next up I'm replacing a model of grass for something more 3d

[dull oar]

yea I cant get this to stabilize, some objects are stable but most objects that use tiled textures arent stable. The object I attached that mesh to yesterday is one of the stable one

[timid trout]

Is it foliage?

[dull oar]

some trees are stable yea, sand bags, trucks, the odd floor prop but most arent

If i set "rtx.geometryGenerationHashRuleString = positions" we get in game but if i dont add "positions" the level doesnt load as we crash. I get slightly more stable hash (doesnt update EVERY frame if I remove "indices"

in the end I went with "rtx.geometryGenerationHashRuleString = positions, geometrydescriptor" which made it slightly more stable than before

"rtx.geometryGenerationHashRuleString = positions" with just this we're stable until the camera moves

[radiant belfry]

that's a very low amount of references/points for geometry hashes to be based on. i don't think it's safe to use that

#1097563444137427056 message

Mark's explanation here

using just a single one is likely not good

[dull oar]

ah ok I approached it backwards adding bits, i'll try adding them all and going backwards

[radiant belfry]

i'm about to start that process for Barnyard and Flatout

good luck!

[dull oar]

you too mate

[dull oar]

removing indices makes it slightly more stable but thats the best I can do I think

[static tangle]

Note that just having the geometry hash stable isn't the goal for geometryGenerationHashRuleString - that's what we use to determine if a mesh asset matches frame to frame or needs update. You could get a bunch of rendering errors if you have too little data in there.

[dull oar]

so am I ok to carry on if my goal is to add new meshes, materials and lights or is all hope lost and I'm stuck with just textures?

[static tangle]

the asset hash rule is separate from the geometry generation rule. asset hash stability is needed for replacement

geometryGeneration is for rendering

[dull oar]

sorry I'm a dummy, do you mean I might still be able to add new meshes and lights?

[static tangle]

yes. The asset hash rule needs to be detailed enough that when you replace a mesh, you don't accidentally replace other meshes that have the same hash.

The geometryGeneration hash (which is what the debugView shows) needs to be detailed enough that it changes when there's an actual change to the source data. - that's why there's a lot more stuff in there by default than in the asset hash rule

[dull oar]

https://tenor.com/view/denzel-washington-my-heart-omg-beautiful-relieved-gif-5511635

oh mark you've made my day, got so worried

[static tangle]

Just be aware that changing the asset hash rule will change all the mesh_HASH prims in new captures, so you would need to re-apply any mesh captures

[dull oar]

Should I be adding something from this list (maybe everything?): "positions,indices,texcoords,geometrydescriptor,vertexlayout,vertexshader" the "rtx.geometryAssetHashRuleString =" line in rtx config and checking the debug view of geometry hash then?

[static tangle]

debug view shows the geometryGeneration rule, not the asset hash rule. it should probably be showing the asset hash rule... I may just make that change, actually

You could play around with the geometryGeneration rule to find stable hashes, then just use those hash components in the asset hash and revert the geometryGeneration rule to what it was originally

[dull oar]

right, this is as stable as I can get the mesh hashes
https://www.youtube.com/watch?v=_BLbXbLI_L4

[static tangle]

they're changing with camera movement

[dull oar]

as long as I remove "indices" they are yea

[static tangle]

what do you have in the geometryGeneration rule right now?

odd that the indices are the unstable part, those are usually pretty stable

[dull oar]

"rtx.geometryGenerationHashRuleString = positions,texcoords,geometrydescriptor,vertexlayout,vertexshader"

[static tangle]

what happens when you remove vertexshader from that?

[dull oar]

goes from updating everything every frame when moving and when still about updating every 5-10 seconds to what you see above when i remove indices

same as the video 😦

this is it with indices added
https://youtu.be/5blaoCtRnNo?t=34

[static tangle]

"texcoords,geometrydescriptor,vertexlayout,vertexshader" try like that?

I think your game may be pre-applying the camera transform... which makes it really hard to have stable replacements.

Although, what is the giant purple box? how is that showing up stably like that?

[dull oar]

so props are stable, trucks, sand bags, anything thats made with unique uv's i seems, tiled textured objects flash

[static tangle]

right... they're probably batching geometry together or something

which is going to make replacing any of that basically impossible, unless you can find an in-game config option to change that behavior

[dull oar]

this crashes on load

into the map, ui's fine

[static tangle]

(just as an fyi - all of the walls, floor, and ceilings in portal have unstable hashes that change when you move between culling zones. we only do replacements of props and lights)

[dull oar]

oh very cool, might be able to get away with it

[static tangle]

at this point, if the props are stable with the original hash rule, I'd recommend just sticking with that and only replacing props. You should explore if there are options to change the game's behaviors here, but I wouldn't get your hopes up for replacing that geometry

[dull oar]

yea ok cheers mate 🙂 if its good enough for portal rtx it's good enough for me

maybe in the future we can attach stuff to the world rather than to meshes and just make the old stuff as ignore or something

[static tangle]

We've tossed around ideas for ways to recognize entire maps / levels based on the instances or something, but that's all theoretical for now

[radiant belfry]

regarding this:
i found that for another game, positions,indices,texcoords,geometrydescriptor,vertexlayout was the most stable for rtx.geometryGenerationHashRuleString

so i should also apply those same values to rtx.geometryAssetHashRuleString to ensure captures function properly as well?

[static tangle]

I would only add extra values to the assetHash rule if you're running into situations where meshes that should be separate are being combined

like if you have meshes that are identical except for their tex coords, and you want to replace those separately, then your asset hash should include texcoord.

but if you have meshes with scrolling UVs that you want to replace all in one go, then you really don't want texcoords to be in the asset hash

Also BTW - just merged a change so that the debug view uses the assetHash instead of the geometryGeneration hash, so that it will accurately reflect what the capture / replacement systems will see

[radiant belfry]

ah, that makes sense. i was just hoping this could potentially fix some of the issues regarding captures in these games

[radiant belfry]

very nice, thank you. i'll update immediately

[static tangle]

I think the actual issue you're running into is a compatibilty problem with vertex shaders and the capture /replace systems. I mentioned it earlier to the guy working on those, but it may be good to also put up a github issue so it actually gets tracked

[static tangle]

got pulled away, but wanted to point out that the change I merged in hasn't actually finished building yet:
https://github.com/NVIDIAGameWorks/dxvk-remix/actions/runs/5150202285

so update once that's ready

[radiant belfry]

would it be possible to have debug view options for both assetHash and geometryGeneration?

with this latest build i've noticed that Barnyard (which showed unstable hashes with previous builds in debug view) is now showing stable hashes without the rtx.geometryGenerationHashRuleString adjustments.

however, the rendering issues persist that were fixed when removing vertexshaders from the defaults of rtx.geometryGenerationHashRuleString

[static tangle]

I planted a bug in some ears about adding all the hash components and rules as alternate debug render modes, hopefully that actually goes somewhere. (or you could do it yourself, I posted the code locations for it somewhere.... maybe in general?)

[dull oar]

updated to latest where it shows asset hash in the geo hash, stuff changes colour still 😦

got hold of some cod2 console commands and FINALLY got cheat mode working in single player so going through every option. like for example the game render is super stable without any work if you turn off decals. what you saw yesterday kim can be fixed with

r_drawDecals "0"

[dull oar]

after a little bit of playing around here's a level from the single player
https://youtu.be/6gh0vO74cL4

[radiant belfry]

wow, nice work

[dull oar]

just setting r_drawDecals "0" get you that

/sv_pure 0
/sv_cheats 1
/spdevmap eldaba
get you to the level and while in game
r_drawDecals "0"
you dont really need to do this though, just mark decals as dynamic decals and terrain as terrain and you're golden

[radiant belfry]

gonna pin that, lol

[static tangle]

feedback from one of our devs:
"They missed tagging some of the layers for the blended rocks either as decals or as terrain."
(awesome video BTW)

[dull oar]

it makes me so happy to know you guys are checking this out 🙂

I just nuked decals out of existance with a console command, if i tagged everything properly as with my carentan level it would look awesome

two new materials today, cobbled stones and a painted wall sign 🙂

[dull oar]

all done mate, check this out 🙂
https://youtu.be/xc6oRzI9DOE
found out if you enable god mode, no clip, zoom the heck out so you see everything THEN enter the command "r_lockpvs 1" to lock culling so stuff no longer disappears you can temporally stabilize the mesh hashes, don't think that'll help us with mesh replacement though. makes for a stable lighting set up for a video while we wait for a better method.

[static tangle]

well if you can script that or something so it happens automatically at the start of each level, maybe

[sage nimbus]

excellent work 👍

[dull oar]

Managed to stablize the hashes for static meshes by disabling static mesh cashing with smc_enable "0" now I can replace grass, trees and props, just not walls, floor or building bits. 🙂

[mystic yew]

Yes I know... This was a sad time for foreign names in games, I think french was not the worst, for arabic or japanese I imagine the developer just putting random symbols

[dull oar]

I think I'm going to change the designs for all these paintings so when I do release my carentan mod I'm not distributing anything from the original game. Just remix files and unique textures.

[mystic yew]

when the time come and if you need help for french or anything Normandie related, I will be happy to help you

[dull oar]

That's really nice to offer, thank you. I'll ping you with my designs when I'm ready.

[dull oar]

little video of progress so far, still loads to do and had to mark decals without alpha maps as "ignore" or you get depth sorting issues so it's all very clean looking.
https://youtu.be/Cpq5pXWN7Uc
just played the single player level "rhine" which has loads of my new textures and also zero visual bugs, might capture that tomorrow. stable hashes on tree's, props, weapons and tanks. Gonna make me a tank at some point 🙂

[hoary geyser]

Hi thanks for let us know the issue. And we have pushed a fix for this VRAM issue, you may try it on the latest code 🙂

[dull oar]

oh thank you so much, I'll grab it right away 🙂

can confirm, no longer running out of memory and crashing on me 🙂 solid 31% memory utilization the past 5 mins of playing with anti culling on.

[hoary geyser]

Nice! Thanks for help verify

[marsh hinge]

Wonder if it looks this good in World at War. Would be cool to play custom zombies with RTX

[dull oar]

You'd need to disable all shaders for rtx remix to work. I've had a look at the config files and it's super shader dependant. You can set shader model 2.0 though in COD4 which I think is your best bet if COD2 doesn't do it for you

[timid trout]

@harsh marten I think you should edit that 🙂

[harsh marten]

shit I tried to replace it with one of the community images

[radiant belfry]

to do that, all you have to do is put a link to a community image in the post

but now that it's deleted, i think hope is lost unless Nomad does it

[harsh marten]

Sorry about that

Call of Duty

[marsh hinge]

I thought maybe /r_fullbright disabled shaders but nope

[dull oar]

Going to be a list of hundreds of changes I would think. Starting with switching to shader model 2 and disabling water, it's all going to be shader driven vertex displacement

[marsh hinge]

If only WaW was slightly older man

[dull oar]

Like COD4?

[marsh hinge]

Yeah

[chrome onyx]

you can force shader model 2 in waw through the console or in the configs

but for some reason all visuals will be black. the audio plays just fine tho

[marsh hinge]

Weird. I didn't even know forcing it was possible, but I guess it doesn't matter since it's black. Unless someone smarter than me figures out why it does that.

[chrome onyx]

an uneducated guss of mine would be that it only exsists because WaW is essentially COD4 but modifed quite a lot on the back end. In that way its there since it is on cod4 but none of the assets are setup on shader model 2. Hell, I can't get shader model 2 working on cod 4 properly either

[dull oar]

If you open remix while in game and the screens black do you see any textures?

These config files for COD4 are very cut back. Would be a good starting point for turning off even more features https://totalgamingnetwork.com/forum/discussion/total-gaming/154617-cod4-configs

Here's a list of all cod4 commands. For cod 2 I look for relevant ones and give them a try. I'd turn off things like screen blur first, that's a post process effect and might be why your screen is black

https://www.gamerconfig.eu/commands/call-of-duty-4-modern-warfare/

[chrome onyx]

Yeah the textures would appear in remix

even when the entire screen is black

[chrome onyx]

The menus work just fine in Cod4 with shader model 2. But trying to play the campaign will get stuck on a cutscene frame or a green screen while the audio still plays. The multiplayer loads and you can get in game but no ray tracing

[dull oar]

I'd start looking for screen shaders to turn off. Motion blur, depth of field, stuff like that. Seems like shader stuff to me. Post process effect's

[chrome onyx]

if only i could get fullbright working in mp

I couldnt get the command to apply and i need to know the console names of maps to force load with devmap

[dull oar]

/devmap mp_killhouse

now you can do all your commands in here

[dull oar]

oh sorry forgot to tag

[chrome onyx]

still no luck unfortunately

i messed with many commands

[dull oar]

If I gather some promising looking ones do you mind trying then out for me?

I don't own COD4 on pc.

[chrome onyx]

sure want me to hop into the streaming vc?

[dull oar]

No that's ok. First let's make sure our settings are the lowest we can set
https://www.intel.com/content/www/us/en/support/articles/000007051/graphics.html

[chrome onyx]

they should now be all set to those settings except Hz

[dull oar]

r_altModelLightingUpdate "1" <not sure what options we have here
r_cacheModelLighting "0"
r_cacheSModelLighting "0"
r_dof_enable "0"

r_debugShader "1" this might be good, will have something like 4 options

r_normal "0"

[chrome onyx]

r_altModelLightingUpdate is either 1 or 0

let me vid_restart since that command requires it to apply

oh that isnt working

[dull oar]

I got excited then tbh

[chrome onyx]

this has 4 options of random colors

[dull oar]

Should swap the shaders to a debug one.

Might get some models, crazy blue ones or something

[chrome onyx]

different versions of rainbow

[dull oar]

Any models rendering?

[dull oar]

Hang on you can see stuff?

[chrome onyx]

always

[dull oar]

Thought it was black lol

[chrome onyx]

waw does the same shader effect

[dull oar]

Could you show me your texture capture window please. You need to make the HUD as UI and you might end up rendering

With path tracing

What you see here is model normals with the debug shader

[chrome onyx]

texture capture window?

[dull oar]

Remix overlay

The second window is the game capture window

[dull oar]

Damn look at that

Could you see r_debugshader "0" please and screen shot

[dull oar]

Oh snap this looks exciting

[chrome onyx]

i to this day have no idea what r_developer (1 or 2) for the life of me

[dull oar]

Lol set developer 1 and you can do things like r_showportals

When you join me in the culling hell you'll know all about portals

[chrome onyx]

theres a /HiDef command

[dull oar]

Interesting

Saw a detail one as well

[chrome onyx]

r_showportals 1

ooo

/HiDef is the only command to give me the "read-only" message

[dull oar]

Hmmm

R_portalfinecull_0 to limit culling and stabilise some hashes

Smc_enable will stabilize props

[chrome onyx]

that command doesnt exist

[dull oar]

Oh yea, boo

Is it path tracing do you know?

[chrome onyx]

it isnt from what i can see

this is with the shader model 2 enforced

[dull oar]

What if you set legacy materials to pure white in rtx remix?

In material overrides

[chrome onyx]

nothing

turning off vertices disables visuals tho

[dull oar]

Right so we got shaders for sure. Cod2 doesn't do that

What does it show with force white diffuse on legacy materials? Can you share a screenshot?

Sorry I'm asking a lot

I see it's on sale right now, might pick it up. Worst thing that happens is I have to play an awesome game a bit

[chrome onyx]

nothing happens, are you refering to the options in rendering? i cant find a version in the textures menu

[dull oar]

It's at the bottom of the rendering window

First window

[chrome onyx]

honestly id rather get waw working rn but that game we are at a stand still until it actually renders more then sound in shader model 2

[dull oar]

Rasterized for sure then

Didn't like that one so much. Preferred the older cod's. Played all of them. Cod united offensive was my jam

Open GL unfortunately

[chrome onyx]

for me, my jam is WaW, Bo1, Bo3, and cold war

[dull oar]

A treyach enjoyer. Maybe one day mate.

[chrome onyx]

anyway there has got to be a way to disable the smoke and snow fall fx

[dull oar]

Yea fx_draw

Or fx_cull 1

In cod 2

[chrome onyx]

mw3 is my fav Infinity ward title, but I just feel like IW just doesnt understand how to make a good cod mp lol

[dull oar]

Nuke town is a classic for a reason

[chrome onyx]

ik

treyarch just gets it

banger map after banger map

bo1 has to have the most legendary map list of any fps game ever

[dull oar]

United offensive was trey arch. Rhinevally is the best best ever. We had Dedicated servers for it for nearly 15 years until Activision shut down the servers last year

[chrome onyx]

official servers?

now we gotta fingure out how to disable the sun shadows

[dull oar]

Full bright does that

r_drawSun "0". Won't turn off the sun but makes decals render properly for some reason

[chrome onyx]

heh

night vision still works

[dull oar]

Lol yea we aren't path tracing

To turn off lighting r_lightMap "Unchanged"

Try white which is 1 if I remember correctly

It's all baked lighting in 2007

[chrome onyx]

what does grass go under?

[dull oar]

Grass blades?

Legacy cutout

[chrome onyx]

not what i meant lol

i mean command to disable

if it has one

[dull oar]

Oh r_mow

[chrome onyx]

ig they removed that command

[dull oar]

Lol it's a joke, like now the lawn

Mow*

[chrome onyx]

i feel like there is a game out there with r_mow as the grass toggle

[dull oar]

Lol prolly

Draw entmodels or something

Xmodels perhaps

Gets rid of trees as well though

Ok shot in the dark but try turning off the hud

hud_enable "1"

Try 0

[chrome onyx]

i was messing around with fullbright to see if toggling it would change anything with hud off

i believe cod doesnt truely disable any shaders in fullbright \

[dull oar]

Nah just renders the diffuse

[dull oar]

Still getting passed through the shader

[chrome onyx]

thats with fullbright off

[dull oar]

In the texture capture you have a white square right?

Mark it as sky or don't mark it as anything

[chrome onyx]

i set it to sky nothing changed so far

[dull oar]

Ah damn. I can switch to raster in cod2 with that trick

Right I think that's me for the night. Got work tomorrow

[chrome onyx]

alright, have a nice night

[chrome onyx]

So this is an older shot but this is what forcing WaW to use shader model 2.0 looks like.

Remix hooks to WaW in shader model 3.0 as you can see in this one. It actually breaks the ingame lighting and assets but still no ray tracing

[dull oar]

Oh forgot to mention as of latest motion blur on the player character and gun looks LOADS better. The player is rendering into the motion vector properly. My guns no longer all noisy and fuzzy.

I'll get a video this after work.

[dull oar]

super stable see 🙂 awesome stuff

[sage nimbus]

Wow 😮 awsome

[dull oar]

added some bots with meatbot 🙂
https://youtu.be/EDoqRjngYDo

[dull oar]

I think I've done all I can do to stabilize these mesh hashes. I'm stuck.

They ARE stable until a mesh gets camera culled that's sharing the same material then the all those objects update. Maybe if we can scale up the mesh bounds in script?

Cod 2 uses c++ and the files are openable in notepad++. The game zips are full of these script files ending is .GSC. editing them and getting your changes is game is as easy as running the game again but I can't code at all. I swapped the teams around and that's all I could manage.

Zooming up outside the sky box with no clip, looking down at everything and entering the command r_lockpvs 1 stops the hashes updating still, its fine for a small multiplayer map but won't work for single player, view distance is too much so it misses things and if the game loads a mesh mid mission you can't see it.

Any help from a code mind would be greatly appreciated. We're so close

[radiant belfry]

i suck with c++ and can barely do python, but i'll take a look when i get a copy of the game

[dull oar]

Dude you're the best, any help would be hugely appreciated

[radiant belfry]

🙂 hopefully i can actually help, lol

[dull oar]

it seems fairly open to people who know how to code. all the scripting is done in these plain text .gsc files. problem is they might as well be in ancient Egyptian. for example this is _load.gsc

"// Do various things"
yea seems about right 😛

[radiant belfry]

yeah, that's not that bad. the problem for me will be interpreting how it's interfering with Remix

[radiant belfry]

did you have to use a tool to unpack the files?

[dull oar]

winrar 😛

[radiant belfry]

lol, wow

[dull oar]

just plop the modified ones back where they came and run

[radiant belfry]

They ARE stable until a mesh gets camera culled that's sharing the same material then the all those objects update. Maybe if we can scale up the mesh bounds in script?
could you get a video of this happening? i'm not sure i understand

[dull oar]

yep one second

[radiant belfry]

that's way too easy, lol. surely there's a catch 😛

[dull oar]

i swapped the americans for russians the other day, all i had to do

https://youtu.be/2pY6Bh75PjM
so if i lock culling via r_lockpvs 1 I get stable hashes, nothing updating or culling and everythings stable...until I move the camera moves and stuff starts to cull. You can see in the tri view I turn on in the video that stuffs culling and appearing and as it does the hash updates.
it's the brushes that are the problem, they're getting batched together based on material and have to update as stuff disappears.

good news though, if you fly up high with no clip outside of the sky box your outside of the portal system and the game shows everything. so you just r_lockpvs 1 and your free to edit anything you like, rock solid hashes. I've attached lights to buildings and reloaded, ran my lil procedure and my building gets lights 🙂

[radiant belfry]

nice 🙂

as for the brushes, how did you determine those are the issue?

[dull oar]

only things not stable regardless of locking the PSV. If you turn off static mesh cashing they're rock solid, same for plants, bushes and tree's.

you can also see them all grouped together in omni as well

[radiant belfry]

hm

what's the name of that particular map?

[dull oar]

I uploaded all my COD2 files to this github issue a few weeks back, it's got my config and console commands in the instructions
https://github.com/NVIDIAGameWorks/dxvk-remix/issues/28

open the cod2 multiplayer and the console with "`" key and type "devmap mp_carentan" press enter

(might need to turn on console in multiplayer options on the menu)

[scenic wolf]

What do you need done with code? Coming from a Lua background this looks like a pretty simple scripting language to me.

Also that's scripting for the maps

Whatever mesh stuff you'd need changed would be done on the engine side in C++

And those wouldn't be plain text

[dull oar]

ah right, just looking for a way to stablize these mesh hashes, a level script to drop the camera up high, lockpvs then drop down to spectate mode would be pretty clever. atleast for multiplayer.

[scenic wolf]

As C has to be compiled

C files would be dlls and stuff

[dull oar]

getting rid of the portal system entirely would be ideal

[scenic wolf]

That might be doable with their custom scripting lang, but I feel like documentation for it would be sparse

[dull oar]

I've seen people making dll's, i have one that pushes back the lod distance. no idea how thats done

oh mate do i have the community for you 😛

same scripting the modern call of dutys use aint it

[scenic wolf]

No idea how the C stuff would be done, C is alien to me

Probably lots of reverse engineering

Or peeking at Quake source code

Probably both

[dull oar]

loads of awesome call of duty 2 information here
https://wiki.zeroy.com/index.php?title=Call_of_Duty_2:_Technical_Reference

the portals, thats whats tripping me
https://wiki.zeroy.com/index.php?title=Call_of_Duty_2:_Portals

a breakdown of what PVS (potentially visible set) is
https://www.youtube.com/watch?v=IfCRHSIg6zo

[scenic wolf]

Yeah as a big source and goldsrc fanboy i know about those fairly well

[dull oar]

if we can stop that hiding the brushes i'm sure we'll be stable and can upgrade the game as we like

[scenic wolf]

Should be able to disable those but it would definitely be C or a very obscure console cmd

[radiant belfry]

hex editing!

[dull oar]

lol that bit lost me

[radiant belfry]

i've been learning a bit more about it recently. might try it tomorrow. i doubt it'll go anywhere, but worth a shot

but to clarify: is the goal for brushes to be disabled entirely?

[scenic wolf]

Disabling PVS is the goal

Basically culling

Needs to go

[radiant belfry]

okay

[dull oar]

brushes are walls and floors, bsp brushes

the portals which have there own section in the d3dbsp (compiled map file) you can edit with the hex editor. apparently 😛

I asked a cod2 modder to recompile the map for me without portals which he did cause he's awesome and although things got more stable he accidentally left some in a couple buildings and thats enough to update some of the hashes. the terrain still updated so thats another system entirely

[dull oar]

you dont have a lot of polygons with cod2 but it's enough, textured the helmet a little bit. looks good with PBR. if I can get my hands on a t pose I should be able to start modelling and do it properly

[dull oar]

I mean business today

[radiant belfry]

sorry i haven't gotten around to working on this

hope you can make some progress

[dull oar]

no worries, just tinkering really

[dull oar]

Managed to get my hands on character models so let's do a pbr reskin from scratch with painter. Gonna be so much fun!

also found a way to import new characters to the game so when I'm done I'm going to look into that and retop my new models with polycounts more on par with the latest call of dutys. It's a Maya 6.0 plugin

[dull oar]

https://github.com/CoDEmanX/blender-cod
Blender, even better.

[dull oar]

Hmmmm

https://wiki.zeroy.com/index.php?title=Call_of_Duty_4:_.MAP_file_structure

A brush can also have a smoothing type applied, or be 'detailed' (not used by the portal-creation system when compiling)

So perhaps if I can edit all brushes to be detailed they'll get ignored by the portal system

[dull oar]

and now the mod tools work 🙂

[dull oar]

STABLE GEO HASHES.

just take out portals in the map editor, save and compile. HOPEFULLY hex editing works for already compiled maps and single player maps

[dull oar]

Just confirmed you can edit the map files in notepad ++ to delete out portals, run it though the compiler and you have a portal-less d3dbsp file that has ROCK solid mesh hashes 🙂 problem is you only have 2 map files so we have to do with with d3dbsp files if we want to remaster the whole game

[dull oar]

Now i've confirmed removing portals stablizes the hashes I'm wondering if anyone would be up for helping to remove portals from a compiled .d3dbsp file?

lots of info here and even where the lumps are in the file. https://wiki.zeroy.com/index.php?title=Call_of_Duty_2:_d3dbsp

I can't do this myself it's well beyond me

[radiant belfry]

wow, that's amazing

great work

[radiant belfry]

https://wiki.zeroy.com/index.php?title=Call_of_Duty_2:_d3dbsp#Lump.5B17.5D_-_Portal_Verts
is this the correct thing to remove?

[dull oar]

I think it's lump 24, portals

https://wiki.zeroy.com/index.php?title=Call_of_Duty_2:_d3dbsp#Lump.5B24.5D_-_Portals

[radiant belfry]

ah, i missed those

that should be fairly easy, i think

[dull oar]

It cant be i've been at this for days

downloaded a decompiler that can output lumps to a text file if that helps

[radiant belfry]

hmm

yeah, not as easy as i thought

[dull oar]

i'm an idiot at this code stuff though 😛

[radiant belfry]

have you tried this? @dull oar
An useful however not documented feature of the cod2map.exe is the -info parameter. It analyzes the given BSP and prints the name, length and entry count of all lumps to console. One can use it for deductions regarding the lump and entry sizes and also to identify the kind of content.

[dull oar]

double clicking that opens and closes cmd. guess I need to tell cod2map.exe to open a specific file?

[radiant belfry]

yeah

also found this https://github.com/wfowler1/LibBSP

works with COD and COD2

[radiant belfry]

what command are you using?

[dull oar]

this is cod2map.exe loaded into cmd

so far nothing after "cod2map.exe"

[radiant belfry]

well it'd be like:
cod2map.exe -info "path\to\map\file"

specify the full path to the map

[dull oar]

will do, one sec

ok we got info

[radiant belfry]

that's handy

so far the biggest problem is that we have a way to decompile these files, but not recompile

so decompiling it kind of makes it pointless?

https://wiki.zeroy.com/index.php?title=Call_of_Duty_2:_Compile_Tools_Documentation

ah, hm. maybe this can do it?

[dull oar]

ah yep i got this, you feed it map files and it outputs .d3dbsp files

[radiant belfry]

good

so we can decompile, modify it, then recompile

[dull oar]

but only 2 map files exist, matmata and a single player level

i recompiled matmata after i deleted the portals in radient level editor and that worked like a dream

[dull oar]

I have no idea what to do with this

[radiant belfry]

decompiling it makes it into a map file. you'd then modify that map file, and recompile it

https://github.com/kungfooman/CoD-BSP-Decompiler

i used this one instead

download the zip of it, then drag the map file onto the exe

[dull oar]

i used another decompiler this morning and got a map file but it's a bit messy, radient couldn't open it

yea i've got that one

[radiant belfry]

ah

i'll try the other one then

[dull oar]

no good i'm afraid, massive maps

you get a list of lump data if thats any good

can pick lump export in the lua settings. you also have to turn off layer names or it doesnt work at all

[radiant belfry]

what do you mean?

i'm compiling the other tool

[dull oar]

sorry I meant this tool is no good, massive maps

[radiant belfry]

what do you mean by "massive maps" though. like how is that a bad thing?

[dull oar]

32 bit software runs out of memory

I did manage to decompile a little map and open that in radiant editor and I was missing all surface materials but could probably swap them back

[radiant belfry]

unfortunately it seems like you'll have to make do with that tool. the other one is actually a C# library, and i have no idea how to utilize that properly

[dull oar]

damn 😦

in the map file it's simply a case of selecting your portal brushes and deleting, maybe I dont need radiant to open a map file

[radiant belfry]

it's just a text file

[radiant belfry]

@sweet cloak do you know of a way to replace content in a hex editor with regex?

we need to replace all occurrences of @...portal...@ and (portal...@
at least, i can't think of a better way

[sweet cloak]

Yea you can do it with imhex and a regex pattern

[radiant belfry]

hm

@portal.*@
i'm trying this and it's not working 😦

ah i see

nope, still nothing. i am doing it here:

my regex may be wrong though

mmmmm

that's close, but i can't remove the entire structure of it with this

[radiant belfry]

@dull oar when you're around, i need your game config file and the latest rtx.conf. i can't get any visuals

i also don't know how you're loading multiplayer maps

i think i modified the tutorial map correctly to remove portals though

also, how are you repacking the iwd files?

[radiant belfry]

lmao. i set shader model to 1

[dull oar]

Lol that guy's looks disappointed to be a chess board

I uploaded my config here @radiant belfry
https://github.com/NVIDIAGameWorks/dxvk-remix/issues/28
Also included instructions to get in a single player level

spdevmap "mapname" in the console

\spdevmap moscow

With my configs and autoex config just press f2 when your in game and if portals are gone you should have stable hashes

You don't need to replace iwi files either. Just place your map in the proper folder structure. Never done it for a single player map but for a multiplayer map make these folders "callofduty2/main/maps/mp" and put your map there. might be sp for single player, you copy the paths from the iwi folders, just extract them all to your desktop with winrar to be sure it's "callofduty2/main/maps/sp"

[radiant belfry]

it's not sp, it's just in the maps folder directly

good to know. i'll try that out then

thanks

[dull oar]

If you want you can rename the map just make sure you copy and rename the matching .gsc file.

[radiant belfry]

i don't see it loading the map file at all, with either cod2/main/maps/[file] or maps/sp/[file]

i checked with process manager

[radiant belfry]

when loading any map through this method:

[dull oar]

Your opening multiplayer?

[radiant belfry]

yeah

[dull oar]

And you have my config?

[radiant belfry]

yes

[dull oar]

Type "seta thereisacow 1337"

devmap mp_carentan should load up a dev server in carentan

[radiant belfry]

my map files don't have any corresponding files btw. it's just d3dbsp

[dull oar]

oh yea its that, just copy one from base game matching level and rename it

to match whatever your level is called

wanna try sending me one? i can give it a go

[radiant belfry]

it gives that error even with the vanilla maps btw

like the ones still contained in the iwt file

[dull oar]

https://www.cheathappens.com/show_board2.asp?headID=43571&titleID=11396#:~:text=Actually the trouble is that,It must work.

well it opens and works 🙂

got a few portals still in there though

[radiant belfry]

is it better than before?

[dull oar]

loads

[radiant belfry]

the thing is, there's no more matches for the string "portal" in the file at all

so if that didn't fix it, then i dunno what to do

[dull oar]

even "portal_nodraw" is gone?

[radiant belfry]

yeah

[dull oar]

oh no hang on the portals are still here

blue boxes

[radiant belfry]

no idea how

[dull oar]

hmm when you go outside the sky box the portals go, thats interesting

[dull oar]

they still function as portals as well

[radiant belfry]

we must be missing something else then

btw for matmata, the original file doesn't even have the word "portal" in it

ah wait, it does

[dull oar]

what if you compare mine with portals taken out vs original? any clues?

[radiant belfry]

yours is totally different and half the size

i can't compare it

[dull oar]

I'll compile it to match with lighting and everything

portals go away after you go outside the sky box

whats on the skybox making that happen I wonder and can we nuke the skybox, remix doesnt need it right? can just add a dome to my stable geo

just realised I can add a custom skydome with mesh replacement 🙂 gonna do that to day

[radiant belfry]

unfortunately that clipping boundary may be hardcoded in the map files

i have a feeling a mesh replacement won't work, but i hope it does

[dull oar]

Darn, tricky ain't it

It works if we have source map files. It's possible

[sweet cloak]

Sorry insane work days going on. I can try to figure out a yaml(?) pattern for them if it’s still neeeded

[dull oar]

That would be awesome. Kim edited them and they still worked but sadly portals remained.

[sweet cloak]

Lemme eat something and I’ll take a shot at it.

[dull oar]

I've gotta get up early for work tomorrow so I gotta go for the day but I'll catch up tomorrow

Do you need a map file? @radiant belfry might be able to hook you up with one if we ask nicely

[sweet cloak]

Actually lemme see if I can get a copy of the game. Been meaning to do a relight of an FPS. 👀

[dull oar]

i'm just using the steam version, works fine

on sale even

[dull oar]

had a bit of a brain wave. so I have the .map file infinity ward released of matmata and the mod tools needed to compile it. so why dont I compile the map with and without portals and whatever the different between these two files are the portals?

would that help track down portals @radiant belfry and @sweet cloak ?

[radiant belfry]

yes. i didn't know that was possible

[dull oar]

I've also exported it without anything basically so the d3dbsp files are 20mb

I'll be ok to upload these right? as anyone can download these with the mod tools, compile and get the same thing?

[radiant belfry]

can't upload map files here

[sweet cloak]

So what does it need to be replaced with

Or did you mean delete instead of replace?

I looked into the pattern stuff and it’s actually a rust / c++ syntax so I’ll just do it with regex, hopefully.

[radiant belfry]

well, replace with null, 00

the thing is, it didn't actually fix the issue in-game

i did it manually for a couple files

you might have better luck though

i could have done it wrong

[sweet cloak]

What’s the indication that it does work? Stable hashes?

[radiant belfry]

yeah

there's also some sort of map viewer that shows portals in-game

[sweet cloak]

Ah, you can use a binary pattern to find them, but I think it's just easier to do by hand tbh

[radiant belfry]

for how many maps there are, i dunno

[sweet cloak]

Ah. Is the length variable?

Ugh can't get remix to run with the game. Keeps saying GPU not supported Windows chosing my integrated card I bet

Running out of ideas

[sweet cloak]

Just had to power through

[sweet cloak]

How do I extract the map files to remove the portal bits?

[radiant belfry]

this

they're in the .iwt files, which you can just open with 7zip

@dull oar can walk you through it a lot better. i was barely getting anywhere

[sweet cloak]

Can I just put them back in the iwd files once I'm done?

[radiant belfry]

apparently you don't have to. you can just create the file structure in the main game folder

so like main\maps\mp\
or main\maps\ for single player maps

personally i had no success with that, but tadpole said it worked

[sweet cloak]

Okay, so back to the first part; what part do we want to remove? ( -665.217 2076.14 -4 ) ( -825.224 2076.14 -4 ) ( -825.224 1940.02 -4 ) portal_nodraw 128 128 0 0 0 0 lightmap_gray 16384 16384 0 0 0 0 is a typicaly string that has portal in it

Does the whole thing just want to go away?

[radiant belfry]

basically whatever structure is specifying a portal

from what i could tell, it's what i had mentioned earlier. like @ ....... portal ............ @

i was unable to copy it properly for some reason. it turns into odd ascii characters

[sweet cloak]

Oh so I want to do it on the .d3dbsp file and not the .map?

Looks like @dull oar was working in the .map file

Rough way of doing it, but it might work:

• search for portal
• click on result
• Press key combination to delete the whole line

Now, I am certain there is more "refined" and defiently faster was to do this but it does meet our goals

Gonna go grab a drink and run it for 500 times and see if it doesn't end up deleting sys32

worked just fine

[radiant belfry]

okay, sorry i was gone for so long. yes, we need it done in the d3dbsp file

at least... as far as i understood

if not, then i just wasted like 3 days

lmao

if only tadpole were around

[sweet cloak]

Lemme see if I can get a crude automation for the d3dbsp

Nah that's going to be the binary pattern stuff for sure

[radiant belfry]

even when done manually, i wasn't getting it right. then again, i was only deleting the text that said "portal", lol

[sweet cloak]

I'll bank on it being the .map

[radiant belfry]

i think there were issues with the .map files

recompiling it into the d3dbsp (which the game reads) was problematic iirc?

[sweet cloak]

Hm

Okay lemme try and see if I got it working right. How do I load a specific map?

Actually, I'm going to wait for Tadpole to return

[dull oar]

Hey sorry I'm in the UK, was 2am 😅

Ok so .map files only exist for one level, Matmata. By removing all the lines that reference portals and compiling the map I got stable hashes.
For every other level we don't have a
.Map file and have to edit the compiled d3dbsp directly if we want to remove portals

So the load the game with rtx you need to set your render preference to dx7 to remove shaders. You can either open the game without rtx remix and do it from the graphics settings or you can add this line to your player config file

seta r_rendererPreference "dx7"

.now to turn on developer console you need to turn it in it game options from the main menu. Once you have that open console and type in

Devmap mp_name of the level

[sweet cloak]

Now it’s getting closer to 2am here

[dull oar]

Oh mate I'm sorry. Really appreciate all your help with this buddy

6:30am over here mate

[sweet cloak]

No problem

[sweet cloak]

Is this what you meant by removing the portals by the way?

I can run through all the files with that brute force technique

[dull oar]

Yea thats what I had to do by hand

But that's a .map file and I don't have any more of them

[sweet cloak]

Gotcha so those are all done?

[dull oar]

I only have one .map file

All the rest are compiled d3dbsp files

Unless were talking using mods and fixing up custom maps to work for rtx which would be great as well

[sweet cloak]

Not yet, once we figure out how to remove them from the complied I’m sure we can automate it so we can do any map.

[dull oar]

Its all that hex stuff so it gets complicated mate

[sweet cloak]

For the d3dbsps, what are the blob start and end values? Is it in one of the documents you posted?

[dull oar]

Yea that website is great, let me find you a link one sec

[sweet cloak]

Cause I can get it to 00 out between the matches.

[dull oar]

https://wiki.zeroy.com/index.php?title=Call_of_Duty_2:_d3dbsp

[sweet cloak]

Also, 010 editor is going to be the best one for doing this I think. Imhex is a bit too hacker oriented in its scripting language to do it easily.

[dull oar]

Also COD4 using a super similar structure of .map file so the d3dbsp is nearly the same thing. Lots of good info here
https://wiki.zeroy.com/index.php?title=Call_of_Duty_4:_d3dbsp

I used editpad which I saw someone else mention for map editing but I think they were mostly editing the plain text entities at the bottom of the d3dbsp file

If you open your d3dbsp and search for 0x80000000 0x00000000 which indicates a portal you get a whole load of hits

I've tried swapping it for another tag like no marks with 0x00000020 0x00000001 but I have no idea what I'm doing so getting errors when loading

At the start of the d3dbsp file you get some references in plain text to portal and portal nodraw you can replace. Turned a portal into a collision with that the other day. Progress? Maybe?

It still functioned as a portal once I no cliped out my the prison I made from myself lol

[sweet cloak]

Yea deleting the portal reference will mess up the map since it’s based on offsets and such.

So we need to remove the entry from the header and the actual data right?

[dull oar]

This has my rtx config and profile. Should get your game working. I've also tagged all the textures in the multiplayer map carentan. In the main menu open the console and type then press enter

Devmap mp_carentan

One you get in game open console and type in

/r_smc_enable 0
/r_portalFineCull 0

[dull oar]

I think so yes

Basically what you did to the .map file you gotta do to the d3dbsp

[sweet cloak]

Yea I just gotta figure out the approach cause the d3dbsp gets a little tricky to keep track of what each part of the data belongs to who

You have to make sure the offsets don’t get messed up when things get removed.

[dull oar]

I deleted the brush name above the portal as well if the whole block of text mentioned portals. Not sure if relevant but I can run your .map file through my compiler and check results if you like

[sweet cloak]

I’m already in bed can’t send maps from here.

[dull oar]

Lol snap

[sweet cloak]

I wonder if someone has already created a pattern for the d3dbsp in imhex or 010.

That’d make it easier

[dull oar]

What I have done though is compiled the only .map file I have with and without portals using the exact same compile settings.

The difference in the 2 d3dbsp's will be portals

[sweet cloak]

Isn’t there a map file in each bsp file?

[dull oar]

No the source .map files infinity ward never released. They included two .map files with the mod tools

[sweet cloak]

Weird. I just grabbed a file and threw into the decomplier and it spit out one.

[dull oar]

Or I'd just edit the .map files, compile and be done

What map file?

[sweet cloak]

The one from my video

[dull oar]

Assumed that was Matmata

You gotta be careful with this. Apparently some map files leaked and I don't want any part of that noise

Whole source code or something. I can't find reference to it online but I've seen COD4 map in COD2 and see it mentioned by people

[sweet cloak]

I don’t believe so, it’s title is crossroads

[dull oar]

That might be one of them I think mate. Best just delete it tbh, stick with the official matmata.map file

[sweet cloak]

Like it never even happened.

[dull oar]

You have no idea do you, just downloading files and having fun. Then you find out the evil backstory or something 😅

[sweet cloak]

[dull oar]

Was downloading custom map files last night and downloaded a cod4 map. Thinking "wow this is so accurate they even modelled modern day cars, must have took forever!"

https://tenor.com/view/we-were-so-naive-brad-arnold-3doors-down-we-were-so-innocent-unexperienced-gif-21286419

[sweet cloak]

I’ll look into this tomorrow. Hopefully I can find something so I don’t have to start from scratch

[dull oar]

Nice one, thanks mate

Get you in game soon playing with your awesome lighting

[dull oar]

Thinking about it even if we successfully remove all portals then what? For me this is just an art project but for others they may want to play the game like this. It's not like we can release the d3dbsp's is it, they aren't ours to give away. And we won't be able to go online as our levels no longer match the server.

We've identified the portals are the problem. Maybe we use that info and tackle it another way.

Call of duty 2 uses idtech 3 btw so if we fix this here we fix it in a lot of games. Infact every BSP based game will have this exact portal culling issue including valves portal. Mark mentioned earlier in the chat the bsp brushes in portal rtx also update as you leave the test chamber, that'll be as you pass through a culling portal i bet. If we can stabilise the brushes here you could stabilise the brushes in the exact same way for every idtech 1,2 and 3 game and even give us understanding about how to apply this fix to other games of the era.

Maybe this isn't a game based fix at all but rather a more global rtx remix issue and how it deals with brushes getting culled

[sweet cloak]

I know for portal rtx he said the floors and walls didn’t have stable hashes

I will say, not having stable hashes for those makes adding lighting require more creativity since you have to find something that is stable and unique near it to host it all to.

But that’s the fun of it

[dull oar]

Yea, all props and plants are stable mind you

If you fly the camera outside the sky box portals go away. Then you can lock pvs and play like normal with stable hashes

[sweet cloak]

I’ll probably do that and beg mark to fix the hashes while we try to figure out something.

[dull oar]

But you can't load new stuff in story mode, only locks your camera view, have to do it every time you load a map and you loose all small plants

Begging mark my latest hobby

[sweet cloak]

Are there stable hashes in the map editor by chance?

I know unrealEd would gladly use RTX remix, even when I really didn’t want it to.

[dull oar]

I'm not sure, probably not it's not not really like unreal. Kinda like hooking remix to blender or something

[sweet cloak]

UnrealED injected it into each quad view so it was very not performance friendly.

I’m not sure my train of thought with the map editor here

Anyway, I’ll def focus on getting that pattern setup. I’ll likely go with 010 editor to begin with and then maybe port it to imhex eventually(tm)

[sweet cloak]

Does the bsp files share the same format as quakes?

Cause there’s already a pattern for that in 010 editor

[dull oar]

I think they're similar.

[sweet cloak]

Good starting point then

[dull oar]

Call of duty 2 uses a modified quake 3 engine and compiles maps to .d3dbsp whereas quake compiled .bsp files. I believe

[sweet cloak]

Correct. The pattern looks for bsp files.

Silly question: is it possible to use radiant or iw3xo-radiant to remove the portals?

[dull oar]

Only if you have the source .map files. Can't open a compiled d3dbsp file

Iw3xo is for COD4 I believe

[sweet cloak]

Would it work for cod2?

[dull oar]

Im not sure, we don't have the map files though do we

[sweet cloak]

It loads d3dbsps

[dull oar]

No way

[sweet cloak]

https://xoxor4d.github.io/tutorials/iw3xradiant-d3dbsp/

[dull oar]

I think that's a call of duty 4 tool mate

[sweet cloak]

Okay, found a slightly more hopeful source for the d3dbsp format, a crudely written forum tutorial

https://www.itsmods.com/forum/Thread-Tutorial-Extracting-a-d3dbsp-file.html

5-Search the word: skycolor , all d3dbsp files start with skycolor, I am taking the example of rust, you will find this(this is not cleaned yet), this is the start of the d3dbsp file:

Code:
{."skycolor" "0.87 0.94 1"."skylight" ".56"."_color" "0.960784 0.827451 0.647059"."ambient" ".01"."classname" "worldspawn"."sundirection" "-20 -12 0"."suncolor" "0.960784 0.827451 0.647059"."sunlight" "1.5".}

6-Now comes the loooooooong part, just click and start scrolling down until you see the last }, after it, will be all weird symbols without sense, there is where it ends.

Aw man it says “rust”. I hope it works for cod2

[dull oar]

According to that zeroy website cod4 and 2 d3dbsp's are very similar so fingers crossed

[sweet cloak]

I’ll still try and see if it produces a result, if it works that’ll be great. If it doesn’t then we know what to do if we try CoD4

[dull oar]

Cod4 hooks but it's rasterized. I've got all the textures though, no command gets me any further than that. I've also seen a mod to edit shaders, wonder if we simplify with them with that tool will we get a result

[sweet cloak]

Seems like there’s lots of tooling for 4 so I wouldn’t be surprised if we could pull off quite a lot with it.

[sweet cloak]

Is there a good test map for doing all these? I kinda wanna setup a manual unit test so I’m not having any variables if it works.

[dull oar]

Want me to compile the Matmata file with and without portals for you?

[dull oar]

I've tried to open a cod2 d3dbsp with this, wasnt having it 😦

i also own cod4 🙂 my fruit killing kills are meh at best

[sweet cloak]

Damn. Well hopefully the hex editing turns into something that can be quickly applied to all the d3dbsps.

[sweet cloak]

Okay culling solved for Underground 2, sights set onto CoD 2

[dull oar]

Your unstoppable! I sure hope so

[sweet cloak]

Would just disabling loading portals do it?

It only gets called from one function

[sweet cloak]

I ponder

https://tenor.com/view/thinking-tap-spongebob-spongebob-squarepants-contemplate-gif-5837190

[sweet cloak]

I will have to track down that function though, since that is a mac exe.

[dull oar]

That sounds like what we're after don't it.

You also have something called cells that portals make.

[sweet cloak]

I do remember seeing something like that mentioned in the debug

[dull oar]

R_singlecell renders just one cell and besides the terrain stabilizes geo hashes

[sweet cloak]

Okay found a path to that function hopefully

Just a lot of labeling ahead

The path there is going to end up looking like this

[dull oar]

here's what we get when loading up a level. only does it the once when you join so fingers crossed this is the bad boy

cull group? occluder? cells and portals we know about.

[sweet cloak]

That's part of the R_LoadWorldInternal function

Green is that function. Red is the R_LoadPortals one

Aw man, there isn't a _GetRefAPI in the retail build it seems. At least from what I can tell

[dull oar]

guessing thats bad?

[sweet cloak]

Nah it's probably there. I just can't find it easily

[sweet cloak]

The quest shall continue tomorrow

[dull oar]

have a good one mate

[sweet cloak]

Might have to find an alternative route to the loadportals function. I think it’s in a separate DLL in the retail pc game.

[dull oar]

ah rats, yea looks that way dont it

gfx_d3d_mp_x86_s.dll and gfx_d3d_x86_s.dll

[sweet cloak]

Ohhh it’s [loadportals] probably in that DLL tbh.

I could see where that gets called possibly and figure it out that way.

[dull oar]

https://fabiensanglard.net/quake2/quake2Polymorphism.php
this might help?

oi it's bedtime!

and this is poor bedtime reading material

[sweet cloak]

Ah so I’m not looking for GetRefApi in the retail build

Rather GetGameAPI

Which will be a vftable?

[dull oar]

https://tenor.com/view/ah-gif-23580102

I have no idea but i'll cheer you on

[sweet cloak]

    {
        game_import_t    import;
        
        
        import.linkentity = SV_LinkEdict;
        import.unlinkentity = SV_UnlinkEdict;
        import.BoxEdicts = SV_AreaEdicts;
        import.trace = SV_Trace;
        import.pointcontents = SV_PointContents;
        import.setmodel = PF_setmodel;
        import.inPVS = PF_inPVS;
        import.inPHS = PF_inPHS;
        import.Pmove = Pmove;
        
        // 30 function pointer assignation skipped
    
        ge = (game_export_t *)Sys_GetGameAPI (&import);
        ge->Init ();
        
        
    }```

There’s one just like that in the game exe

[dull oar]

GetGameApi is used at startup to exchange info between the server and the game dll. It is called by the server passing in a tables of functions to the dll (the game imports). It returns a struct o' pointers back to the server, the game exports.

[sweet cloak]

So by using that function table, I can figure out where the loadportals is used

[dull oar]

and then kill it with fire 🙂 perfect

[sweet cloak]

Going to try using Ghidra since I don't understand how external calls work in IDA Was more confusing

[dull oar]

lol fair enough

[sweet cloak]

Turns out it's all handled in the DLL

I couldn't find that vftable again, but the DLL was super easy to find what we're looking for

There she is

Now how do we make it not load them

Maybe this?

Let's see what happens

[dull oar]

omg

[sweet cloak]

What's the command to load the map you've been using?

[dull oar]

devmap mp_carentan

[sweet cloak]

The game didn't immediately crash so that's a vast improvement over my previous attempts

That command didn't do anything

[dull oar]

oh you need to press tab

devmap, tab, mp_carentan

[sweet cloak]

Doesn't do anything

[dull oar]

\devmap mp_carentan

[sweet cloak]

ahhhhh

Also didn't do anything

[dull oar]

oh your in single player

[sweet cloak]

Oh yea I only did the single player gfx dll

[dull oar]

spdevmap elbada

[sweet cloak]

Man I'm striking out with these commands for some reason

[dull oar]

ok one sec i got you

[sweet cloak]

Game crashed when loading a map

[dull oar]

damn 😦

[sweet cloak]

My jmp modifications prob messed up something so

Very common to do since things reference eachother based on offsets

I can see if x32dbg will do it

Alright we're back

[dull oar]

just pop these lines into your config_mp.cfg and config.cfg found in Call of Duty 2 > main > players > username

seta thereisacow "1337"
seta sv_cheats "1"

[sweet cloak]

Once I crash the game trying this I shall

Need a snack break tho. Got the munchies

[dull oar]

To open the full console press shift ~. You have cheat protection on, that's why \spdevmap eldaba didn't work last time. But the two commands in your config file will fix that

Might get some information about your portals as well in the full console

[sweet cloak]

Says it can't find that map

[dull oar]

oh spelt it wrong didnt i 😛

a bat and a ball makes a b and a drum and a stick makes a d. Come on tadpole! your in your thirties

[sweet cloak]

Damn

It does trigger during the loading screen so I'm very confident it's that

[dull oar]

ok so your in the right spot

[sweet cloak]

Does your remix menu only open once?

[radiant belfry]

the progress that can be made when someone actually knows what they're doing 😛

nice work

[dull oar]

no it's super stable

[sweet cloak]

Wait I'm over thinking this

[sweet cloak]

I can just tell it there's zero portals in the map file

result = dword_1CF3B1C is just setting result to the number of portals found

Hm. I think the it breaks some offset in where it's expecting things in the map

I'll take a step back and see where it actually uses the portals

[dull oar]

you have cell's as well, think they're made from portals but you cant actually make a cell in the map editor as far as i understand it

you have commands like r_singlecell. stupid artist talking shit but could you potentially manipulate that to show all cells at once rather than just one?

[sweet cloak]

No I think you're onto something. There's a mislabel or something becuase LoadCells is labeled with Portals and LoadPortals is labeled with Nodes and leafs.

No wait I just mixed it up. They're labeled correctly

I can't find r_singlecell in the debug file

Wait. There it is

Are any of these new or untested?

[dull oar]

I've seen all of them before. These ones are key for remix.
seta r_smc_enable "0" < stablizes props (static mesh cache)
seta r_portalFineCull "0" < stops brush meshes flashing all the time in mesh hash debug view
seta r_lodScale "1" <plant distance
seta r_forcelod "0" < no more lod's high poly mesh only
seta r_lodBias "-1000" <overall lod distance, if you want a side quest -10,000 would be sick

[sweet cloak]

Wouldn't surpise me if -10,000 causes overflow errors

[dull oar]

-9,999 will be fine though right

[sweet cloak]

Not sure

r_lodBias = (*(&ri + 25))("r_lodBias", 0, -998637568, 0, 8320);

[dull oar]

I'm just joing mate 😉

[sweet cloak]

Oh you didn't test -10,000?

[dull oar]

once you get in game see what you think of it, -1000 is max

about 50 feet infront of the player plants stuff disapears

no worries though, problem for another time aint it. just saw it and remembered what it does

[sweet cloak]

r_showPortals does what it says on the tin right?

Trying to find where the game uses portals in the rendering function

[dull oar]

yep, even does it in pathtracing

thats a good one then

r_showportals 3

r_singlecell 1 culls everything outside the cell your standing in

[sweet cloak]

That's R_VisitPortals which seems like it might have potential

[dull oar]

thats new

[sweet cloak]

But it is very windy and complex so won't be fun

[dull oar]

never seen that one before

quake 3 as a r_noportals

[sweet cloak]

R_VisitPortalsForCell

[sweet cloak]

Not found

[dull oar]

damn

r_nocull is another it has

cause why not, quake has 2 we have none

something i found with kim last week, if you noclip outside the sky box with r_showportals on the portals go away

[sweet cloak]

Maybe it's cull groups? Or is that something else

r_portalMinClipArea and r_portalWalkLimit ?

[dull oar]

not sure, any mention of anything like vis?

[dull oar]

useless, got controls for that in game, never saw a difference and tested them a lot

[sweet cloak]

Damn

[sweet cloak]

Same with the clip area

Hm r_singlecell shows the same. So maybe there's something else

[dull oar]

what about portalfinecull ?

that made brushes much more stable

[dull oar]

i'm not sure what this means

[sweet cloak]

Not sure either. But it seems like r_portalfinecull + 8 points to r_drawPrimCap

[dull oar]

r_drawPrimCap limits the total amount of primatives in the scene

also got an r_drawPrimfloor

[sweet cloak]

For the fine portals, we got two things looking at it

The AddWorldSurfaceWithCull makes me think of adding surfaces and checking if they're culled?

[dull oar]

yea makes sense, does sound like that

[sweet cloak]

Wanna say this looks like a visbility check

> 0.0 and all that floating math

[dull oar]

oh nice find

just remembered about PVS (potentially visible surface). thats the core of the culling in this engine

[sweet cloak]

Does the AABB Tree need some looking at? I know that was part of the fineportal

[dull oar]

only saw that for the first time today.

https://www.youtube.com/watch?v=IfCRHSIg6zo

[sweet cloak]

Well well what's this in the R_AddWorldSurfacesDpvs?
R_FrustumClipPlanes(a1 + 200, &standardFrustumSidePlanes, 4, &v67);

A classic

[dull oar]

might be another system for props, they cull conventionally behind the camera

big shadow casting trees disappear with a camera turn

[sweet cloak]

Does r_zfar adjust the total rendering distance?

[dull oar]

yep, you can set any number so i go for 1 million

[sweet cloak]

So if you set it to like 1, it doesn't draw anything after [whatever 1 is]?

[dull oar]

think so, let me check

[sweet cloak]

It checks if it's set to 0.0 and if it is, then it uses some other variable for the value

[dull oar]

yea thats 10

[sweet cloak]

This is also something of interest
v12 = fmaxf(*(float *)&dpvsConfig, r_zfar);

Aw man

We gotta enter uncharted waters in the debug symbols file

[dull oar]

jesus look at that

we sure just not loading portals is a dead end?

[sweet cloak]

If you don't load them then the offsets get all messed up in the loading system as far as I can tell.

Hmm there's r_skipPvs

[dull oar]

yea odd one, just renders nothing

it's backwards

[sweet cloak]

[dull oar]

-x!

ez

[sweet cloak]

if ( !*(_BYTE *)(r_skipPvs + 8) )
  {
    if ( a2 < 0 )
    {
      v58 = rgp[1063];
      if ( *(int *)(v58 + 252) > 0 )
      {
        v59 = 0;
        v60 = 0;
        do
        {
          R_AddVisibleSurfacesInCell(v60 + *(_DWORD *)(v58 + 256), (int)&v67, v61);
          ++v59;
          v58 = rgp[1063];
          v60 += 60;
        }
        while ( *(_DWORD *)(v58 + 252) > v59 );
      }
    }
    else
    {
      v35 = *(_DWORD *)(rgp[1063] + 256) + 60 * a2;
      if ( *(_BYTE *)(r_singleCell + 8) )
      {
        dword_1896FCC = 0;
        R_AddVisibleSurfacesInCell(v35, (int)&v67, v61);
      }
      else
      {
        R_VisitPortals(v35, (int)&dpvsGlob, &v67, v61);
      }
    }
  }

There's our friend r_singlecell

[dull oar]

oh yea

this one seems promising

you can also lock pvs. stops it updating.

fly over the map
see everything
lock pvs
respawn
stable meshes

nothing new loads though

[sweet cloak]

Lock pvs seems to mess with LOD origin

And in the main render loop, it's really high up in the funciton

[dull oar]

yea its all static, no matter how close or far you get

[sweet cloak]

v42 = *((_DWORD *)a1 + 21);
  v4 = R_CellForPoint(v37);
  v5 = rgp[1063];
  if ( v5 && *(_DWORD *)(v5 + 256) )
    R_AddWorldSurfacesDpvs((int)v37, v4);

So it gets the map data in v5 and the camera point in v4. v37 is if the position of where r_lockPvs was activated if it was.

Anyway I think telling R_AddWorldSurfacesDpvs that everything visible is a good start since the map modification didn't work.

[dull oar]

it's popping up a lot aint it

[sweet cloak]

At best it'll just show everything in all loaded cells.

[dull oar]

ideally, that would be perfect

r_singlecell

in debug. terrain does update but whos replacing terrain anyway

[sweet cloak]

It's our friend from the homework! #1099591203768504421 message

[sweet cloak]

Hm

AddWorldSurfaceWithCull adds surfaces that cull the scene

[sweet cloak]

I think if I have the frustum culling say everything is in view, and then if that doesn’t do it I’ll make all nearby portals as visible maybe

[dull oar]

It's encouraging to see addworldsurfacewithcull actually work in game. think it's the working result no?

[dull oar]

Sounds about right, tackles both systems of culling doesn't it

[sweet cloak]

I tried messing with it and it didn't seem to do much tbh

[sweet cloak]

I’m not quite sure why. It should do something.

[dull oar]

Doing some reading it looks like portals get built into the pvs system during a map compile and are actually discarded once you get in game. I guess what we see with r_showportals is just for debug purposes . Maybe that's why messing with portals post d3dbsp compile isn't working
https://fabiensanglard.net/quake3/renderer.php

Maybe we should look more into pvs

[sweet cloak]

R_SetFrustum (Setup the mplane_t frustum[4]. No near and far plane

That's why the frustum cull loop was only a loop with 4 itererations!

Because the far and near are user controlled 🤯

[sweet cloak]

Yea I think more homework is going to be needed. I don't have a good understanding of PVS.

[sweet cloak]

I'd like to go back to trying to avoid it loading portals like you suggested. I think once the portals are in the engine it's going to be really hard to get it to stop using them.

Plus, it's a known way to success from your testing. Rather than the noncertain outcome of breaking the portal system in the rendering stack.

[dull oar]

lots of good info here, the video from michael explains PVS it all well
https://fabiensanglard.net/doom3/dmap.php

yea I think portals are the key to success.

[sweet cloak]

Ah I think I know why messing with r_loadPortals breaks things: the number of portals is already defined before you get there.

The number of portals is fidgured out in the r_loadCells

[dull oar]

so you will need to change it to be 1 o something in both r_loadcells and in r_loadportals

[sweet cloak]

I'm not sure. The final build of the game is different than this debug file, so the actual implantation may be a bit different. I have to track down the R_LoadCells function to see what it looks like in the retail build.

[sweet cloak]

Final build is really similar. I'll try telling it there's no portals in the loadcell function when I get the chance

[dull oar]

oh awesome! spot on, gonna work on moving my textures to a mod folder so i can share it as well 🙂

[sweet cloak]

Had some more thought to this. Might be something that we want nvidia to look at since the quake engine is so prevalent as the base of game engines.

[dull oar]

Would really help other games. The bsp system we're fighting is in most 2000-2005 games. Hell even portal 1 uses it and it prevented Nvidia from replacing the wall meshes or attaching anything new to them

[sweet cloak]

Ruhoh. That’s not a good sign then.

[radiant belfry]

just "replace" the walls by combining the entire room into a single mesh, then replace the floor with it 😛

[sweet cloak]

Now we’re thinking with portals.

[dull oar]

Dynamically culling meshes getting new hashes. Wonder if they could stop that

[sweet cloak]

Did you figure out what part of the hash generation that made it unstable?

I know there was some talk about that a long time ago

[dull oar]

I stabilised it until the bsp mesh culls part of its self with
#1099591203768504421 message

Think removing indices from the rule made the big difference

[sweet cloak]

Might have to look at how remix works with Quake 3 and then apply it to Call of Duty.

[dull oar]

Oh never did post this here Adam found a github project to make shaders for COD4. Might be able to simplify them enough to get remix to render. It hooks, shows textures, you can hide meshes but it's always rasterized

Oh we did post it here. Well if anyone likes cod4 and wants to kill shaders

[sweet cloak]

I have a COD4 and World at War install ready for when I’m ready to get prypiat and zombies path traced

[dull oar]

Who said you could stop grinding the portal problem!

[sweet cloak]

[dull oar]

Lol

[sweet cloak]

I gotta think of how to approach it better. Or start looking around for modding discords and such to see if someone knows.

https://www.moddb.com/tutorials/modifying-a-bsp-binary-space-partitioning

Also might just start adding light sources to props just to get something in there

[dull oar]

This any good @sweet cloak ?
https://developer.valvesoftware.com/wiki/PVS

[sweet cloak]

r_novis

God if only that worked here

Sam said that's all you need for a source game

[dull oar]

r_novis. Might work for portal

[sweet cloak]

Rip mark

[dull oar]

Missed that one didn't they

But is there any info there that might help us?
