Thread 714810096

how did they raytrace without rtx?

Lost ancient technology.

there is an exact copy of the whole world in the mirror that spins along with the mirror

Just render the level twice it's actually easier than running volumetric physically accurate light reflection models for every square pixel in your level

Who says they use raytracing? There is more than one way to make a mirror effect.
Raytracing is just some method for simulating light and RTX is just a chinese technology for raytracing.
Lol.

Non-outsourced code

I like this game, but the way Dead Island 2 did mirror reflections is atrocious

There is a 2nd camera anchored at the middle of the mirror pointing upwards, which then has its captured view baked into the texture of the mirror object for every frame. Here, the texture is rotated 180 degrees to make it look upside-down like you're looking at a real mirror. So, for every frame that happens, whatever the camera captures will be imprinted in the texture of the mirror in real time. Obviously, this is very taxing on the hardware so the resolution of these reflections are lower and in Sunshine there can only be 2 reflective objects at the same time.

>wait that sounds genius why don't other games do that??
because it takes time to get the camera just right, so devs would just rather slap on the shiny RTX dogshit and tank your frames by 90%. Enjoy!

Parallax corrected cubemaps are amazing and I don't understand why don't more devs abuse them for all windows/mirrors that you're not supposed to be up close instead of going for rtx.

>>714811182
why bother doing actual game dev when you can press the RTX on button and the problem is solved? Why bother animating if you can mocap?
Game devs are so bad these days.

>>714810743
Is there a single game that has a shattered reflecting mirror?

>>714811821
The Spiderman games made by Insomniac used that technique for the buildings windows, iirc.

>>714811821
because they're lazy fucks AND they think that using old tech is somehow shameful. There is a pre-baked method for EVERYTHING you would want (except real-time lighting). There is 0 incentive for games to rely on raytracing and dynamic lighting other than shitty devs (and directors) and shitty management that rush the games. It doesn't help that faggot companies like Unreal push their proprietary tech like lumine and nanite so devs just slap all post processing effects and unreal bundled technologies and call it a day.

Just look at Battlefield 1 or Need for Speed 2015, the games look better than most AAA shit that comes out today. It's fucking embarrassing.

>>714810743
The best way to do a mirror in a video game is not on that image.
Making the mirror completely black so the player can see their real, ugly, reflection in the monitor. This is the true way.
Lol.

>>714810096 (OP)
This plus the displacement map distortion heat haze and water effects is actually insane.

Thank you for your wisdom based Mario autist cabal member

Sunshine is a masterpiece from a graphics perspective

Everything on the gamecube looked way better than the N64, because the 2000s is when the gaming industry had the great realism race. The race actually started in the N64 era but graphics progress peaked in the 2000s. Graphics are literally just getting straight up uglier now every year. We are currently in an era of sucking people dry for money, with DLC, microtransactions, lootboxes, and nostalgia-bait, and many other corrupt practices. We are in the era where the gaming industry exploits retards for money.
Lol.

Nu-hitman, I don't have the gif on hand but it gets posted pretty often

>>714810096 (OP)
this is why i pay 80 dollars for nintendo games

>>714811182
Actually interesting insight, blessed post

How did Deus Ex do it?

>>714812387
Deus Ex Human Revolution. At least they explain in the story why its broken.

ol reliable of course

They recorded actual mocap footage of plastic cataquack models standing on a mirror and put it in the game

how come old games could run an entire second instance of themselves without a hitch to make mirrors but modern games can barely run one instance with 50 crutch meme techs

>>714810743
Raytracing is evil.

>>714819516
They generally couldn't, Deus Ex chugged like crazy on the average setup at the time of release.
Same with games like FEAR. It's why they weren't regarded as universal classics until several years after the fact.

>>714812974
that's what the loading screens are for dummy

It's so weird how nintendo wasn't managed to surpass the water in this game. Mario odyssey's beach levels look like shit in comparison.

>>714810096 (OP)
We don't know how to do this anymore.

>>714810743
screenspace is good at 4k. it just sucks at 1440p because dlss and fsr turns 1440p into 1707x960 (less than 1080p).

>>714811182
Or maybe having dozens of high quality reflective surfaces, is preferable to having merely 2 lower quality reflective surfaces. But sure, let's call the devs "lazy"

>>714817639
Every old game has a reflective surface on a single flat plane, in an isolated room. Why is that?

>>714811182
thank you for giving an actual answer

>>714826290
>having dozens of high quality reflective surfaces, is preferable
Why, there's too many to notice the quality

>>714817639
why are you locked in the bathroom

>>714810096 (OP)
everyone is talking about 2 rendered copies of the level, but couldn't you just copy and flip the one image, then warp it based on the orientation of the mirror?

>>714811182
>devs would just rather slap on the shiny RTX dogshit and tank your frames by 90%. Enjoy!
but I thought adding a 2nd camera was more taxing on the hardware????!? wtf I love memetracing now!

>>714826628
Foolishness.
