Portal 2

[mystic sail]

thats all

[boreal hazel]

the same as what i do for the base rtx mod? (https://github.com/xoxor4d/p2-rtx-base-mod)

[mystic sail]

not the portal but same structure

[boreal hazel]

this one yeah

[mystic sail]

ye and mods folder there

[boreal hazel]

okay and i put it in the mods folder

the mods folder already has stuff in tho

should i put it alongside it? or in this folder

[mystic sail]

its for portal rtx to work

[boreal hazel]

yeahh i thought so, but should i put it alongside it or in the same folder

im assuming same folder like you said but

its broken already i dont wanna make any mistakes 😭

[mystic sail]

just mods folder not that one

[boreal hazel]

cool :D

ill let yk once it installs and i hopefully get everything working

[mystic sail]

small update: i downloaded that zip, i forgot that theres not only rtx remix folder, just drop all files from there to portal 2 root folder

[boreal hazel]

small problem: i already have those folders in my portal 2 root folder

[mystic sail]

and what? its not problem

this folders are by default on portal 2

[boreal hazel]

okay ill drop them into the root folder and let you know what breaks 😭

do i put the .conf in aswell as the folders

[mystic sail]

yes and overwrite files

[boreal hazel]

okay

[boreal hazel]

done

should i run now?

[mystic sail]

ye try it through bat

[boreal hazel]

done, everything seems to be running fine

[mystic sail]

good, one sec will send a command for console to test if maps after act 2 working

[boreal hazel]

okkk ty

[mystic sail]

map sp_a3_jump_intro

just a random map

[mystic sail]

i guess its working!

[boreal hazel]

yippeee!!

tysm for all ur help

[mystic sail]

np mate

[boreal hazel]

will let you guys know if i find any bugs

[boreal hazel]

current state of my game, not sure how to fix

UI is gone, some textures are broken, not sure why as when i launched it a few days ago none of this was a problem and i didnt touch any of the settings before that

how do i fix this 😭

[boreal hazel]

nvm i fixed it by loading the game with the .bat file

but also another bug: the floor disappears in the early chambers when enhanced meshes are enabled

colours are messed up on the screens in the elevator rooms (black and white now)

[mystic sail]

Dev of mod that i showed you said that he gonna fix it in future update

[boreal hazel]

ah sick ty

[wheat geode]

Ye I made a small oopsy in the 1.3

[wispy fiber]

Wait this looks cool as hell

[opaque hawk]

i put the pbr pack in the rtx remix mods folder and nothing has changed, does anyone know why?

[boreal hazel]

skybox in the old aperture levels is bright white

[naive edge]

looking hot 🔥

[wispy fiber]

What maps are the first 2 images?

[wheat geode]

sp_a2_pull_the_rug and sp_a2_speed_gel (portal revolution)

[buoyant venture]

Did you import them? because that’s a DX11 game

[wheat geode]

https://github.com/xoxor4d/p2-rtx/discussions/201 imported the stuff from that into base portal 2
I made this for digital additions (all testchambers and voicelines work)

[west bolt]

When I run P2-RTX for the first time using the .bat file it loads and tries to compiler shaders but gets stuck in a infinite loading loop. is there a fix?

[boreal hazel]

I had a similar problem if u scroll up in the chat what I did might help?

[west bolt]

it boots but after compiling shaders it shalts and asks if I want to stop the program or Wait

[boreal hazel]

yeah it did the same for me

like this?

Or this?

[west bolt]

I toggled the mod and opened the .bat and it worked!

[naive edge]

Its compiling the sound cache

[west bolt]

That's what I thought, How long does that take?

[naive edge]

a simple restart will work - if you are missing sounds then there is a cmd you can enter into the console. It should be mentioned in the troubleshooting guide on the main github page

[naive edge]

It never finishes so I guess letting it sit for a minute or two should be enough

[west bolt]

I see! Thanks for all your hard work on this RTX Remix mod fo the childhood game dude!

btw does putthing the .bat launch options work in steams launch options settings?

[naive edge]

yea it should!

[west bolt]

I just put them there for ease of use

[west bolt]

and when My dad plays P2 He doesn't have to run the .bat file

[thick condor]

heyo i found a community project of a "remake" of P2 in work! It looks interesting, i also don't think they use Remix but i still looks incredible :)
https://www.youtube.com/watch?v=5ovDgRtosGA

[buoyant venture]

Yeah, Portal 2: CE is Raster on DX11, not Remix

[wispy fiber]

@buoyant venture currently at what status is the portal 2 rtx mod been in?

Has it kinda been a stand still for asset development in the past few months

[buoyant venture]

yep, still no progress

we've made more progress in optimization then actual redesigns 😭

[wispy fiber]

:(

[wispy fiber]

with the optimizations lets say someone wants to port a portal 2 mod to portal 2 rtx, are all those optimizations already done or are some need to be manually done through guides and such

[buoyant venture]

I think static rendering would have to be done manually since I know it applies to specific maps, not the whole game
Correct me if I’m wrong @rough ginkgo

And cull markers are also specific iirc

[rough ginkgo]

yeah its manual per level

[worthy pendant]

if I wanted to use a newer version of remix in portal 2 what files would I need to swap?

[wheat geode]

the .trex and d3d9.dll from the bin folder need to be replaced (btw you should use the GTA 4 Runtime since it has almost all the fixes needed)

Colored videos

[worthy pendant]

so I just download the GTA IV mod and put its d3d9 and trex files into portal 2 RTX?

[buoyant venture]

@rough ginkgo

[wheat geode]

that should work

[worthy pendant]

hope the base mod gets updated at some point, ik xorxor is quite busy with GTA IV tho

well it worked, but I thought the GTA IV mod was updated enough to have the legacy emissives option, but I dont see it

[wheat geode]

its still a pull request for base remix

[worthy pendant]

its got RTX particles though, I thought particles and legacy emissives were in the same update

[wheat geode]

sadly not

[worthy pendant]

Thats unfortunate, I planned to use it a bunch

[rough ginkgo]

nv hasnt responded to that PR since it was posted, no idea when it will be merged into main remix

its been about half a year lol

[worthy pendant]

damn

its really handy in GMRTX

[sudden lotus]

Hi! i followed the instructions about adding the GTA .trex and d3d9.dll in the portal 2 rtx build and I'm worried i might have done it wrong somehow, the videos are still messed up for me, also some particles like the confetti for example aren't working now, do you know how to fix this? i would really appreciate your input. Great Mod btw!

[wheat geode]

well the videos are just apart of Digital additons 1.4

and the confetti and some particles would need some more of the fixes the base portal 2 runtime provides cuz the gta runtime wasn't made for portal 2 sooo some stuff is still broken

so i would still use the runtime provided by the portal 2 compat mod cuz it was made for portal 2

[sudden lotus]

Oh ok, thank you for the quick reply!

[naive edge]

How? Did you edit the bik in a certain way?

[boreal hazel]

even when the mod is disabled (using the toggle.bat file) some stuff is still messed up when playing, e.g. portals arent see through anymore, they always look inactive even if you can walk through them, and some areas just fully break like when you look at the skybox out of bounds

[boreal hazel]

this is mostly seen when going through doors i believe

at the very leastin the perpetual testing initiative chambers

does this regardless of whether i run it from the .bat or from steam

[boreal hazel]

thanks!

how do i run these again?

just in the source console?

[wheat geode]

A Remix replacement with a big sprite sheet containing the entire video (has to be sped up to 250 frames to prevent a looping issue) also vram seems fine for 12gb

[naive edge]

oof .. well I was planning to add proper bik support to the remix fork once I update it (so that no replacement is needed)

[wispy fiber]

that'd actually be great ty

what stuff do u have planned for portal 2 rtx?

[boreal hazel]

one thing that i will say that might be nice in the future is support for custom testing tracks like the ones in the communitoy chambers

they work ofc but it has HEAVY fps drops

normally can run portal 2 rtx on like 60fps or more, went straight down to 20

[buoyant venture]

New runtime update?

https://tenor.com/view/tinytim-tim-poor-child-boy-gif-7331148

[naive edge]

NEE seems to be broken (even on a stock runtime)

Would be nice if someone else could confirm that .. and maybe test some older builds to figure out which commit causes that

[naive edge]

@wheat geode

I fixed the emissive surface flickering but that requires emissive surfaces to be tagged as worldui (just like before). Doing that, they produce quite noisy light.
NEE does not seem to like surface batching at all .. @rough ginkgo did you ever come across something like that on gmod? #1289195427119501424 message

[rough ginkgo]

I don't believe so but I will check as soon as i can

[naive edge]

I've pushed version 2.2 which:

• updates the remix runtime to the latest version and includes the portal 2 specific tweaks
• Refactored some of the codebase and got rid of dxwrapper - replaced with ultimative asiloader which should result in less issues for people
• Added bik support as seen in the video above
• Added an installer to help with installation of the comp mod (it can also download and extract the remix mod)

https://github.com/xoxor4d/p2-rtx/releases/tag/v2.2.0

[buoyant venture]

@rough ginkgo we updating the Steam build after so long

https://tenor.com/view/please7tv-please-beg-pray-hope-gif-3860103425950934673

Wait does this have the XeSS changes?

Actually what runtime is this based off? Newer might break our RDNA 2 compatibility

[naive edge]

ToT

[rough ginkgo]

since xoxor4d said ToT yes it has XeSS

its the lastest changes as of now

[naive edge]

I had to remove the add / remove texture hash feature tho

[rough ginkgo]

why?

[buoyant venture]

Fuck

[naive edge]

I didnt want to waste time on that with the new layer system that was introduced. Seemed like too much of a headache and I dont think its thaaaaat useful

[rough ginkgo]

ah gotcha

ngl it was really useful for auto-tagging stuff in gmod for workshop maps, but yeah i can see why it wouldnt do much for P2

[rough ginkgo]

rip RDNA2 / SD

RDNA 4 also sees some performance regressions on the latest master but now that there are 100 commits between my fork and that, bisecting will take forever

[buoyant venture]

If it breaks RDNA 2
I’ll talk with AMD about it

[buoyant venture]

Means our Intel users will also suffer if there’s performance regression

[buoyant venture]

@rough ginkgo you think if we implement Variable Rate Shading
It could help some lower end cards?

[rough ginkgo]

i mean would it really help performance that much?

ik it has its uses in rasterized games but im not sure how that fits with pathtraced stuff

[buoyant venture]

DOOM The Dark Ages has an implementation which has Pathtracing

I could try it there

It shouldn’t be hard to implement
It seems to be extensions like Anti-Lag is

Which reminds me I need to finish Anti-Lag and open the pull request

[rough ginkgo]

lmk when u push a new build, would like to test it

[buoyant venture]

I’ll try to get latency stats connected so we can actually see how it’s doing

I don’t think latency stats is Reflex dependent
It seems connected to the OS

[half topaz]

yeah and it has zero effect on performance, like every other implementation

[buoyant venture]

@rough ginkgo tested VRS with Pathtracing
It boost FPS by a little bit but not a lot

[misty monolith]

why does this happen only when i walk up to this wall

[naive edge]

latest release or are you on an older version

[misty monolith]

latest

[naive edge]

latest runtime is causing these issues .. still investigating that

[misty monolith]

ok

lmfao game crashed now i just hear good jump on a loop

[gilded hull]

fails to extraction stage, even after putting master.zip in folder

[naive edge]

where is your game installed? (the path)

[gilded hull]

It is working through manual mode, it is installed in default steam directly

I located the correct portal2.exe

[naive edge]

Under ProgramFiles ?

[gilded hull]

C:\Users\myUser\scoop\apps\steam\current\steamapps\common\Portal 2

oh yeah i am using scoop

[wispy fiber]

does anyone notice random crashing in the mod?

it'd stutter once in a while before it just like

crashes

hmmmmmmm

[wispy fiber]

@naive edge is shader execution reordering not in the mod?

[naive edge]

uh?

[wispy fiber]

one less option in portal 2

[naive edge]

never seen that option before

[wispy fiber]

optimization for 40/50 series gpus

for me it improves performance by 10 fps

what card do u use?

[naive edge]

I guess rtx.isShaderExecutionReorderingSupported is set to false in the rtx.conf that ships with the comp mod ..
and the initial rtx.conf I've used was made when I had a 3080 so makes sense that its off - I do have a 5090 now

[wispy fiber]

Ya no wonder it was nearly reaching 50ms at 1440p while portal rtx runs it at 39ms

Thx for telling me that exists I’ll change it next time I play

[naive edge]

Thanks for letting me know that this is a thing - will surely help in gta iv 😂

[rough ginkgo]

iirc my 2080 also had access to SER?

or rather it was exposed as a setting for me

[wispy fiber]

Ik for a lot of people 10 extra fps isn’t a lot but it helps a lot with frame generation, extra fake frames + lower latency

I think it was like 60 fps to 72 fps

[buoyant venture]

No reordering though
So you don’t see a performance gain

20/30 series just support accepting the code

[rough ginkgo]

ah

[half topaz]

yeah my understanding is that SER just tells the GPU to execute that function, and if the hardware doesn't support it, I expect the shader compiler will just discard the command

[buoyant venture]

Apparently the game doesn’t need to be published to mess with the workshop :p

[wispy fiber]

have u been able to implement MCPG into ur mod?

[buoyant venture]

I haven’t even updated the runtime yet to Xoxor’s latest

[wispy fiber]

hope mcpg isn't abandoned

[winged wind]

a 5090? that's a huge upgrade my god

maybe is not the better place to ask.. but wich cpu you have with that monster?

i recently got an 5070ti from 3080 and runs flaweslly path tracing

[naive edge]

9800x3d

[nocturne elbow]

What is mcpg?

[winged wind]

so no bottlenecks

wild setup

one of my dreams...is run battlefield v with a 9850X3D at 1080p low settings and have almost 500-400 fps in a multiplayer match

[wispy fiber]

@nocturne elbow mcpg is markov chain path guiding, a method for indirect lighting like restir or nrc

gives better performance than importance sampled (the lowest quality method)

and is overall a massive step towards remix working better on other gpu vendors and older cards, which has been the main drawback of remix

[buoyant venture]

mcpg is gonna take longer, I started working on some other optimizations in the mean time, which you can see the first completed implementation in #general-remix

[nocturne elbow]

Oooooh

THAT'S VERY GOOD

[wispy fiber]

@buoyant venture u still up for using updated portal assets from other people?

[buoyant venture]

I would either have to get his permission or have him join the team which is more preferable

[wispy fiber]

@buoyant venture he allows full permission of the models to be used in other projects with credit

[sinful talon]

Defo not working, installed via "Installer.exe"

[rough timber]

Did you use 'run-p2-rtx.bat' to open the game?

[sinful talon]

Yes, then I put the bat's commands in the Portal 2 parameters line, and it ran like that

[buoyant venture]

You need the .bat specifically to run the game
I find putting the commands through steam does not work

It needs to be the .bat

@naive edge is there any reason the RTX mod needs the .bat specifically, I checked it but it’s just commands but the mod won’t work without it even if the commands are in Steam or in my case as well, Steamworks

[naive edge]

Probably asiloader and winmm blocking

[winged isle]

I have an issue where most fizzlers in old aperture just dont render at all

Fizzlers in general have a lot of wierd behavior, but this one is really bugging me and im not sure how to fix it

Im not sure why its so inconsistent though, its only in old Aperture and its only most fizzlers

[wheat geode]

hi guys
https://www.moddb.com/mods/digital-additions/downloads/digital-additions-14

Finally published 1.4 you can take a look at the update log

[winged isle]

I really wanna ask if i can borrow the gel textures for my own pack lmao

How did you make the moon sequence look not terrible?

Damn, you actually got the fizzlers working in old aperture, i cant figure that out

[wheat geode]

sure all i really did was take a built in normal map and scaled it down many times (0.10 for the roughness and 0.05 for the normal map)

for the moon seq idk I just did? used free textures from #1211706192510844999 message
also attached a light to wheatly's eye to make it bloom more

[winged isle]

Im a little sad gel covered cubes still dont work

[wheat geode]

ngl i might be able to fix that now that i look into it

[winged isle]

That and portal gun lights are like the two big things i have no idea how to even begin trying to solve

Id kill to get the portal gun properly lit up in full rtx, for now i just slapped a blue emissive texture on top and called it a day but its just not the same

[wheat geode]

possible... anyway gonna go to sleep

[winged isle]

Peak

Thats an actual gameplay mechanic that just doesnt work right with the mod

[buoyant venture]

The real Portal 2 with RTX

https://tenor.com/view/jeff-the-land-shark-jeff-marvel-rivals-absolute-cinema-gif-13695558822116321078

[true iron]

ok so im having an issue with the game crashing after i start it its the exacy same as what this guy has https://github.com/xoxor4d/p2-rtx/issues/234 i want bother to restate what he said but i have the exact same logs does anyone know how to fix this?

[wheat geode]

try update you're GPU drivers (fixed it for somebody)

[sudden lotus]

Hey, Great Mod! I was wondering if there was a way to fix the lasers? (not the turret laser, ) for some reason, they look odd.

[wheat geode]

(I didn't make the video)
https://www.youtube.com/watch?v=NHi2MRQv90o

[sudden lotus]

?

[wheat geode]

ah i read it wrong... what do they look like now?

Currently it’s just a red line so I do plan to improve it

[sudden lotus]

now that i look at the images on the moddb page, exactly like this.

[rough timber]

Not sure if anyone else has ran into this issue but glass_window_refract.png appears to be corrupt.
⁨ ![ Renderer ] Failed to load C:\Program Files (x86)\Steam\steamapps\common\Portal 2\portal2-rtx\textures\glass_window_refract.png⁩

Was able to work around the error (which freezes the game) by reusing the observ window png to be in place of the refract window png.

[true iron]

Did that yesterday didn't work

[wheat geode]

it shouldn't freeze you're game...
does the testchamber lights still work? like warm cool and white
with that?

I had to change it so that the compat mod would fail to load it and in turn have a source mod fix the lights and that gives me full control over warm and cool and white lights to be added

[wheat geode]

oh well what gpu do you have?

[wheat geode]

right now gearing up for 1.4.1 a update that will bring colored paint to cubes and turrets
and bug fixes so not really if you dont like the red line or wait until I get to it

[rough timber]

I believe so yeah. I’ll have to go back and test. It was freezing going down a specific elevator the famous way Source engine does (looping short audio interval).
I can go back and let you know which test chamber it was, it seemed it was failing to load the next one before the loading screen even pops up. And then also see if the lights are fine or not with the workaround I placed

The only visual issues I saw with the lights doesn’t seem related to what your describing.
One being the Rattman room in the test chamber where trash hurdles towards you in a series of ariel faith plates has lamps with a light glare texture that seems out of place

And, in the test chamber where Wheatley helps you escape from, the test chamber lights are supposed to go out but never do lol.

But like I said I don’t think those are related to what you’re referring to but they may be worth mentioning for future mod development 👍

[wheat geode]

so it does look like these

"https://www.moddb.com/mods/digital-additions/images/colored-lights#imagebox" when using or not using the observ window.png to be in place of the refract window.png

also that freezing while going down the elevator seems to be the compat mod acting up

[rough timber]

I know I seen the lights like that but I can’t give a confidence yes that I saw them after applying the workaround. Is that a particular test chamber I can test?

I can just go back and test the chambers that those would appear on when I’m able to get on my PC

[wheat geode]

the map used was triple laser but if you could see them after the workaround to not get that error i might be able to remove that thing then

[rough timber]

I'm not seeing the cool/warm lighting difference anywhere in the map. Given this one was what you were referring to?

Well, even with my 'workaround' in place, it seems the game is still not quite stable with the RTX mods. Seems to be quite susceptible to freezing just before loading screens in the elevator. The error loading that file may have been a false positive to the freezing.
I think I was just unlucky that it froze 2 times in a row down the same elevator

I'm going to reverse the change I made and test from then on

Yeah, now it looks as the mod is intended

And the console window doesn't look any different from when the game isn't frozen. So that's completely my fault for believing that was the cause of the freezing.

Now, on the other hand, I am experiencing consistent crashing on the first "The Fall" map. Traversing through the map there's a certain point where the game crashes every time.

and here's the .dmp if you are able to work with it

Also beautiful, beautiful work on all this. I feel bad for not saying that first before dumping everything else on here 😂

[winged isle]

I was stumbling around trying to make a texture/mod pack for some of my friends to play

But after seeing how good Digitals pack is after the recent update i think im just gonna have them download that and just make a small modpack for them to throw on top

It just looks so good, i couldnt one up it if i tried lmao

[wheat geode]

oh that seemed to happen on a settings change...
ngl I cant read anything except one thing

why is it dividing by zero lol
my mod seem's to make it happen more due to ig the size?
Oh I think this is partially my doing...
dont know why remix would divide by zero if you set the max dust particles to zero

The crashing upon the level changing still seems like its the compat mod fault tho
I think...

[rough timber]

Can you set the max to -1 to circumvent that?

[wheat geode]

i just made it disable dust (the setting) overall instead of 0 particles max

[wheat geode]

just released a hotfix that fixes the gel visual of cubes and turrets
and also Fixes a divide by zero crash
and also slightly improved the ending of the base game
https://www.moddb.com/mods/digital-additions/downloads/digital-additions-141

[sudden lotus]

Awesome! does this also fix the lasers? I'm currently downloading the mod so i haven't gotten a chance to check yet.

[rough timber]

How, of all these years playing portal 2, did I never realize the circuits of the Frankenturrets get fried when GlaDOS say the paradox line lmao

It took an RTX mod for me to find out

[rough timber]

I'll have to test the early game chambers again but from The Fall to the end of the game, I experienced no freezing before loading screens on the 1.4.1 update like I did previously

In theory the game should be fully completable with the Digital Additions mod now, albeit some visuals still need buffed out, but still impressed by all the work done on it!

[naive edge]

How did you fix gel on props?

[winged isle]

I think the only thing left that really needs to be reimplemented at this point is the lights on the portal gun

Idk the first thing about modding source games, but would it be hypothetically possible to create a mod that causes the portal gun to swap between two identical models when firing that can each be given a separate emissive texture in remix?

Then again it might just be simpler to try getting the default lights to actually show up, idk

[naive edge]

The light effect is there and working but it’s behind the gun because remix brings the actual viewmodel closer to the screen while simultaneously shrinking it. This is to prevent it from clipping into walls. If you set viewmodelscale to 1, they should be visible (if you set some graphic option to high)

Did not get the effect to be considered viewmodel so never got it to scale with the gun. Other means to offset the effect always resulted in it moving independently with the gun

[winged isle]

The graphic option is shader detail afaik

which last i checked is locked at low by the mod

when i tried forcing it to high the game just crashed

[wheat geode]

The props used a detail texture to apply the paint - use a new base texture with the paint already applied

[wheat geode]

I think It’s possible… I managed to move them I just need like the best values to offset and hope they aren’t lagging behind like I think they are

[wheat geode]

Erm so I may or may not have forgot about that
I can send you a fixed one soon tho since there’s a 2-3 cooldown on uploading the files

[sudden lotus]

Oh ok lol, thank you!

[wheat geode]

this should fix it
put this into the rtx-remix then mods then the digital folder and replace the file

[winged isle]

So, i wanna try messing around with the portal colors, but i found that messing with the sprite sheet colors causes the inside of the portal to just become black

Is there any way to make that not happen?

specifically, i was trying to make the blue portal a bit darker

[sudden lotus]

after replacing the original file with this one, i ran into this issue. ngl, its kinda cool lol, but i was wondering if there was a way to fix this?

[wheat geode]

eh the mod shouldn't be able to do that since i just modified the laser
in you're alt + x menu scroll down to Player model click it and make sure "show in primary space" is disabled

[sudden lotus]

gotcha, does that also bring back the portal gun model?

[wheat geode]

it should

[sudden lotus]

That fixed it, Thank you. Great mod!

[wheat geode]

thanks!

[winged isle]

For some reason, the portal gun has a vertex explosion issue in community chambers, and only in community chambers

[rough timber]

Im surprised you can actually run community chambers lol. I wouldn’t think to try because some levels will have assets outside of the Portal 2 game and just make things look off

I tried doing Co-Op but the game just doesn’t let me do it, can’t remember what the behavior is (whether it error’d or crashed). But I imagine the mod hasn’t reached any Co-Op related assets yet

[winged isle]

Outside a few goo pits not being set as transparent and some lights not working its been fine for the most part

Although any chambers using the beemod portal 1 style just look awful

[rough timber]

Yeah, I imagine so lol

It surprised me seeing Garry’s Mod have an RTX Remix in the works for the same reason

[winged isle]

Im probably gonna go in and start making emissive textures for all the beemod stuff at some point

[rough timber]

That’d be dope👀

[winged isle]

Im not really sure why the gun blows up there and not in story mode though

[buoyant venture]

Pretty sure it's because the mod can't support more than 2 portals so co-op is a no go

[rough timber]

Probably has something to do with how the gun in first person works. It’s actually not in the space with you but projected onto the screen from outside of test chambers
Since community chambers are not pre-planned on where to put the portal gun projection, they probably have a different way of choosing where to put the portal gun.. and the mod doesn’t expect it that way and freaks out a bit

Not sure why it’s a visual glitch like that, but that’d be my guess on why the portal gun doesn’t work the way it does on story maps

[wispy fiber]

@naive edge when making p2 rtx was special engine/api level optimizations did you make that dont appear in normal remix

things like culling

[winged isle]

Any updates on this?

[wheat geode]

not really might continue soon tho

[winged isle]

damn

Maybe my first suggestion might actually be an easier solution lmao

Is it possible to make a mod that swaps the gun between two different textures when firing?

[wheat geode]

that might not be too bad actually lol
if a source pro was here they would be yelling at me how to move a simple particle lol
Hmm wait then again if i recompile the portalgun it just says a checksum error so I dunno

[winged isle]

I wish there was a more dedicated portal modding community

Even if you do get that method working, im still gonna end up giving myself an aneurysm trying to get it to work with the portal gun mod im already using lol

[buoyant venture]

r/Portal

[winged isle]

Most of r/portal is people posting about how they saw a blue and orange coffee mug at work the other day

[buoyant venture]

Lmao

I use it to post applications/teasers

[naive edge]

• More than 1 portal pair (3 pairs are supported in p2)
• various anti culling tweaks such as anti culling around the player and anti culling from the outgoing portal sides perspective
• per drawcall tweaks to allow automatic tagging and hash overrides to be able to create overwrites for things like the gel texture
• various vertex buffer adjustments to effects, gel etc

A lot of other things I can’t recall from
The top of my head (I’m currently on a cruise ship 😛 )

[wispy fiber]

Do you remember adding performance increasing changes that aren’t present in other source remiz projects like hl2 or portal

[naive edge]

Well .. there is still culling so that might improve things in certain areas

Otherwise .. not really

[wispy fiber]

mainly asking cause i remember seeing how in hl2 rtx the entire map is rendered compared to ur project where i think it has the ability to cull certain locations

ya that

look here

[wispy fiber]

@buoyant venture what application did u use?

[buoyant venture]

Radeon RayTracing Analyzer
https://gpuopen.com/radeon-raytracing-analyzer/

Need a AMD GPU to capture scenes
Though you can view captures on a NVIDIA GPU

I have used it for Portal 2 RTX before

[stuck talon]

@buoyant venture Should I disable the RTX Neural Radiance Cache? Also what error log should i look for? I was playing a minuted millions and it happen to freeze when entering into room (the map has portals that teleport you to WILDLY different areas. I'm shocked it worked as well as it did tbh. I'd send screenshots but I hella dont know where they went lol

[stuck talon]

I got a random remix crash while playing a community map. Crash occured during Into The Multiverse Part 4 (yeah part 4 I got really far lol)

[wheat geode]

New DA update!!!

Just like more support for community maps/support for more custom light sources
and turns out I was not done with the base game as I improved the lighting in the finale maps

@winged isle
Might be doing it wrong (probably am as it seem like its connected to the wrong bone)
(not included into 1.4.2)

[rough timber]

lmao that looks so bizarre

[buoyant fjord]

Amazing work

[buoyant venture]

Could it be this one?

That or NVIDIA is cooking something

[rough ginkgo]

what is that one from

same vid?

lol yep

thats what i get for skipping

[wispy fiber]

where is this being forwarded from?

[buoyant venture]

Patched portal2.exe?
Does that mean we can just use the .exe now? 👀

[boreal hazel]

everytime i run the game, it just says "Steam is not running, you must install steam to play the game" despite having steam open

i installed the latest patch, uninstalled and reinstalled the game, tried running with it enabled and disabled but nothing works

this is the log from when it happened

[boreal hazel]

i can get into the very first screen but the second the main menu loads it instantly closes

[boreal hazel]

@naive edge any ideas on why its doing that?

[naive edge]

did you try copying the launch args from the bat and put them into steam?

[boreal hazel]

the read me file told me to clear any that i had there

[naive edge]

yeah but its fine if you copy things from the batch into there

[vast fiber]

I noticed a small problem with the latest version of the mod, I wanted to know if it comes from the compatibility mod or the RTX mod

Before, the light was good, but now, everything stays on

And since the problem appeared after updating the compatibility mod, I guess it could be caused by that

[boreal hazel]

it didnt work 😭 I may have to clear my cloud data on the game just to get it running

[boreal hazel]

i havent been able to fix it so im just gonna have to delete my cloud save of the game

rip

[rough timber]

I hope you know you can back those up 👀

[boreal hazel]

im gonna have to figure it out 😭 my cloud save has the mod data installed on it so I cant load it

I already tried

[boreal hazel]

still doesnt work 😭 i disconnected it from my cloud saves and did a fresh install

my portal 2 is cooked

[boreal hazel]

i was never able to fix it :( any help?

[naive edge]

the main github page has uninstall instructions

[boreal hazel]

where? i cant seem to find it :(

i would much prefer to actually get it working properly rather than it being fully gone but i genuinely can't seem to figure it out 😭

[boreal hazel]

yeah i did that to no effect

i meant either fully remove it from the game files or get it to actually load on startup, whenever i play the gmae it just crashes and says you need to be running steam in order to play

(even though it very much is running)

[naive edge]

setting these cvars should be enough or what issue are you running into?

[boreal hazel]

literally the second i open the game in any way it crashes instantly and says "steam is not running. you need steam in order to play"

Looking up breakpad interfaces from steamclient
Calling BreakpadMiniDumpSystemInit

theres the log

from the command prompt

this was an issue on the old version and the new version as i updated to the new one to try to fix it

it might be the old files still being in the game files which is why i tried to a fresh install but i do not know 😭

[naive edge]

Uh what are you trying to do? I thought you wanted to uninstall?

[boreal hazel]

either get it running properly or fully uninstall it so i can at LEAST play the game normally

i wanted to uninstall it because its unplayable currently

so its just get it working SOMEHOW

[naive edge]

Follow the main page uninstall instructions then

[boreal hazel]

i did, it didnt do anything

if you mean the thing to toggle it off

i did this

still didnt open

[naive edge]

Probably because your game is installed under program files and the batch does not have permissions to rename files

So you have to remove the asi file manually

[boreal hazel]

which one is that?

cos i do not have one of those listed here

[naive edge]

p2-rtx.dll

[boreal hazel]

ah alr

so not .asi

(i know nothing about this stuff lol)

and i just straight up delete that file?

what about the rest?

[naive edge]

But you’ll need the original exe for that to work

[boreal hazel]

uhh of what?

portal 2 itself?

which files do i manually remove

[naive edge]

Why not just uninstall the game and then clear all files in that folder. Then reinstall

[open rampart]

@boreal hazel idk if it’ll help, but I see there’s a little shield next to the exe - maybe it’s a permissions issue blocking rtx launch?

[boreal hazel]

it gives me a popup asking for permissions and i do give it said permissions but still doesnt wanna open

okay, update: now it doesnt crash immediately but the second it gets past the copyright screens it crashes (the second it starts loading)

[boreal hazel]

it didnt let me delete them so i just moved them all to another fresh folder 😭 hopefully that works

[boreal hazel]

did the fresh install and it still crashes at the loading screen and still asks for permissions somehow

yeah i got nothing

[wispy fiber]

@buoyant venture what changes/additions have you made to your version of xoxor's mod for your project?

[buoyant venture]

The only thing merged has been FSR 3.1
I wanna rebase it though because our testers reported a performance boost on RDNA 2

As for upcoming features: things like ReSTIR-FG, NRD SH, etc
Only mentioning what I’ve worked on because I don’t want to push pressure on anyone else by saying their features as confirmed

[wispy fiber]

what improvements does restir fg involve in the paper beyond just caustics

[buoyant venture]

Resolves better GI detail in general from what I remember

It’s also better than ReSTIR-PT

[wispy fiber]

does it still involve the heavy temporal issues of restir gi?

[buoyant venture]

What issues were there?

[buoyant venture]

I wouldn’t know, lol
I haven’t tested it like that

[wispy fiber]

restir gi doesn't handle changing lights well

[buoyant venture]

If you wanna try, there’s some early code up before I handed it off
