@@VALLANCEGAMING Gotcha. I don't mind giving a specific tech demo a pass. :D For instance, my personal "I wish they had X" moment was watching the stock model android avatar doing its momentumless running and jumping. That actually prompted me to search for any UE5 demos of modules or whatever where people have done work on a player character's physics interactions with its environment and movements. Like sinking and bending the knees, chest and head dipping and leaning forward after landing a jump, or the little weight shifts to start or stop running. Bouncing and catching itself with its hands against nearby rocks, the boat, etc. I found hit momentum demos, but nothing else. Maybe I'm just missing the right keywords to search. :P

[@VALLANCEGAMING]

@dakaodo Those exist, that's how games have better player controllers than the standard UE5 tech demo, the foundation was expanded upon. This tech demo of water physics is indeed a tech demo that shows a wide variety of properties and the purchasable version will have further accessibility I'm sure, it might also be expanded upon to include more features, an oversight would be the example I mentioned.

[@privatebryan1924]

Do you guys think that realism is a good thing for gaming? I have my own reservations, I mean playing Elden Ring with real physics might be either really good, or really bad because it's no different from reality. Isn't a game meant to be a distraction from reality?

[@perfectionbox]

The waves don't actually crest, which means the water is a heightmap texture and probably computed by a vertex/tesselation shader. The local momenta are probably also stored in a vector map texture to easily update the whitecap material. Quite clever, and of course will run very fast. But the main problem is that it's what they call an "expensive material", the kind of thing you can't have if you want to have 60 fps with all the other stuff a game needs to do.

[@chrismathewsjr]

we'll see. i foresee even more bugs and microstutters in our future

[@MadsterV]

you mean the realtime fluid simulation of a whole beach could impact performance? who would have thought!

Looks ugly off the bat too sadly.

[@perfectionbox]

I find it okay, but waterfalls could use tweaking. It looks like the heightfield in that part has a large vertical vertex delta, the momenta get huge, and the whitecap texture gets really stretched. The heightfield simply can't support a true vertical slope, let alone break up into independent pieces of falling water, and you'd need more texture resolution vertically to support slower momenta at the top.

[@deloford]

It runs at over 250fps at 7680x2160 on my PC so I suspect you could quite easily fit some other game stuff in there!

[@nottoogoo]

Physics that are interactive are game-changing in my opinion. It's the one aspect in games that is missing. It takes a static world into a simulation. Destructable environments, weight, lighting.

[@CC-qx7hk]

Finally. I've been saying we got the graphics and lighting down good enough now a days. They need to start working on particle fx, fluids, faces, and material deformation in way that can be used in gameplay or just in the world in general. We are damn close to nailing the uncanny out of faces too *Changes the water to pee color* "Wow...that is- that is really pretty." No but fr looked gemlike especially the bright blue was super pretty. One thing I noticed tho is it seems like currents don't affect the character.

[@Omili]

We are SO close getting performance friendly full scale real time physics simulation that collide with everything from small details and items up to large structures and so on. When that happens, it's new and truly life changing peak in digital world. Think about booting Skyrim and watching grass, flowers and trees sway in wind while dragon flies above you and stays in air because it's wings generate uplift in real simulated air/wind etc. As you walk down the road, all your items that are shown on your character are actual physical items that you can pick up, use and put back while interacting with your player model, backpack, clothes, cape and weapons. Your characters hair is rendered real time with actual physics and collide realistically with all equipment on your character while also swaying in the wind and changing depending to the random simulation of wind direction and speed. When you reach river and waterfalls you will hear it far before even being close and once there you see animals drinking from it, moving bit close animals notice you and react realistically by not instantly running random direction because they have full blown AI controlling the actions and decisions. Bandit attacks you from behind but you manage to deflect the strike with your sword and feel the heavy collision of 2 swords like in real life. But that didn't feel realistic enough so you close the game and start it again while wearing your VR headset, and continue the journey fully emerged into the world. Funny things is... almost all that... is kinda possible already... We have all that without the physical real time simulations but looking at this video and how well the water simulation works. I think we are damn close reaching the point where everything I said above is possible for everybody with average or better computer. And when that happens, we have reached actual simulated world and next all we can do is figuring way to go in that world like one would boot a computer and have couple hours gaming session with friends. Well that is far away but fun thought.

I agree this is one of the most impressive things ever. Most realistic water simulation. Never thought this would be possible, but there it is. Look how realistically the foam dissapates on the rocks 12:00

[@Stonehawk]

I think once it calculates what the sustained flow characteristics of the geometry at a spot are, it doesn't need to *continue* calculating it. It can continue using the same calculation, and these characteristics can be somewhat pre-calculated to create a baseline state that can be modified at-need by interfering factors as they occur. As states stabilize, they can be 'parbaked'.

[@privatebryan1924]

Wait what? Dude could become a millionaire with this only lol

[@sikliztailbunch]

15:31 the depth doesn´t cost any performance, because there is only a waterlevel grid being deformed. There are probably some helping particles or voxelfields involved but never even does this high performant sim, fll up the scene to the bottom with particles. Maybe there are some very low resolution voxels involved but even that might be limited to some area around the waterlevel in order to transfer velocities from subsystem to subsystem. The fact that textures still move, when the sim is paused, reinforces my assumption: My highly educated guess: It uses Houdini´s heighfields or a system, that works very similarly. It does't really "care" about how deep the water underneath is - performancewise, because only the surface moves, hence, needs simulation info to deform correctly. It is all clever displacement. Down in the depths there is literally nothing going on so there is most likely also no calculation going on. Or maybe a voxel tesselation of a 10 by 10 by 10 meters per voxel or even lower for general current at that depth level. It at all. You can easily use a single vector down there that uses a small area around the player to determine current direction, so a player can get sucked down, pushed up and so on. The depth is ultimately just a simple float value involved in the calculation deformation solver. That's why the wavegenerator demo works. But not because real particles are being pushed and meshed. That still takes ages at that scale. Even on a 4090. I don´t want to downplay this. It´s amazing and extremely sophisticated in terms of optimization. But there are some limitations. It cannot create separated entities like a cluster of particles that can splash off. It cannot produce waves that bend over and collapse like for a surfing game. And will not be able to fill up a container and walk around with it and spill puddles with it. But I guess, it will not take that long until we can. This is already a giant leap into the right direction.

It's funny how people can be amazed of things that doesn't require actual power from the GPU. It's 4 cylindrical columns shaded in a dense fog. The GPU sleeps on it, 250m or 8192m, doesn't matter. :D And the problem with new games that they are not want to employ artists and programmers who are optimizing clever tricks that puts a realistic and optimal illusion in front of the player, they just want to brute-force all by the engine. These games lack the human touch, the creativity. They want to outsource LOD-s to AI, they want to outsource map generation to Finite Element Method. And they surprised that people like the games in the past better.

I've looked at some new games coming out and they look real and I might even say some look better than real if that makes sense. I remember the days of playing games that was 4/8/16/32 colours only and now this in a span of 30 years, just incredible... Nice video mate!!! ❤❤❤❤ Wow, so when you then started swimming I lost it, so normally games are written by code I believe and its sort of set in stone. You can walk, run, swim, fly in certain places and that's it. Its not really fluid, its whatever was programmed and then the code needs to be changed if something is required to be changed but this seems to be a code that is "ALIVE" and changes based on what is happening on screen. So this is the opposite of programming as before because you experience what was programmed and see that on the screen, now what you see on screen and experience is writing or updating the code, hence the environment changed (flooded) making it swimmable. This is insane!!! Our lives will never be the same since AI came to play,. I've just installed the first AI system in the world for the Courts and Tribunal in Scotland (So the first Court and Tribunal in the world to use this 😁😁😁, so we will be a template for others to come) system to transcribe/translate court cases where in the past it took 5 humans a week to do one days video recording and cost thousands of Pounds to now on-prem AI with on-prem LLM's (due to security concerns) doing it in 106 seconds with a 96& accuracy (the 5 humans was around 92%.

This Unreal sim is great, but it's not doing anything special really, that's why it's also resource friendly. I just hope that more games incorporate more sims and extra mechanics to calculate in their games so they start utilising more cores.

Around the edge off the beaten path at 1:13 the water slows as the course of flow changes and the area behind the fall in 1:19 is near completely stagnant as the water cannot flow away from there, but has been filled. Its amazing. Still not sure how I would use any of this stuff, or for what reason lol. Would be nice to go back to game dev, but I tend to enjoy making text based or 2d games (like classic GBA Zelda lol)

[@Libertas_P77]

That fluid dynamics demo is a glimpse into the future of VR and gaming in around 5-10yrs time. Love it.

[@neoqueto]

This is one of the most impressive things I have ever seen. And Bluedrake makes an amazing job showcasing and explaining it.

[@Vartazian360]

Amazing. But yet UE5 still cant run a game without stuttering

[@alanfi7646]

Volumetric water is one of those effects I've waited ages for. Simply amazing, my mind is actually blown right now.

[@scorpius666999]

Umm, this isn't simulation in a classical sense, I mean, it's not "deep ocean water" (pretty cool post-processing though) and I don't think this will fill caves the way you described, but it looks cool regardless. I saw the first version of this I think a year or so ago, I do remember that first map you showed. It's cool the whole thing is being developed over time.

[@EviLLivEClan]

The boat takes like no collision when the water runs into it. It just starts to float instead of being pushed too.

[@romulusxyz6722]

BeesWithGuns. Miss you dude. Thrilled to see you thriving!

[@m_tth_w9647]

Bru whenever I say damn it's js gets even better wtff

[@NollieFlipX]

Man I'm speechless, this is completely mind blowing! And you can see how close this tech is from even simulating full barrel wave. I think people don't realize how absurdly difficult is to pull what this dude just did! This programmer deserves some kind of prize, I would risk saying he deserves a tech nobel. It is that insane! I wonder how far will this go, specially for multi density fluids

[@austinbergeron7150]

Imagine the survival games we are going to have, for example an island survival game would be absolutely beautiful with this, could have things wash up on shore with waves, giant storms, difference in high and low tide, fishing, diving and having current affect your speed in the water. Maybe rain causing floods and pools of fresh water. Games are going to get absolutely insane in the next 10 years and I'm all here for it

[@TruthIsKey369]

About time......... where's all the destruction at?

[@chopchopofficiel]

This tech will make the first surf game

[@user-ne9sd4ow1o]

There was PS2 surf games if i remember correctly

[@TropicBlunder]

I just don't understand how this is possible? The amount of math calculations ever second I would assume be enough to melt down an array of 4090s.Of all the demos I have seen UE5 do, this is by far the most impressive. And it is not even close.

[@Samuraiii62]

What? Operation Harshstop is from you? Sick, I bought the supporters Edition. Keep on!

[@lamsmiley1944]

I hate that I can’t just enjoy this tech these days. My mind spends the whole time thinking about how it could look so much better. I used to be able to appreciate tech where it was at, now I’m just cynical.

[@chrismathewsjr]

also we don't ever get to see this stuff used in much outside of tech demos. when i do sit down and try out something that has added new features, i find i have a distaste for the regression in microstutters, bugs, lack of depth, etc.

[@TooToo246]

I remember playing AC Origin for the first time, and just marveling at how good the water looks. How murky it is near the banks of the Nile river, and then it slowly gets clearer and more blue as you sail into the sea with more clear scattering of the light on its surface.......To this day, I think the AC games have the best water in games (not including this demon of course)

[@Baleur]

More UE5 tech tests and yet we wont see any games using this for another 10 years, like with Nanite or Lumen. Why? idk why. Ive done UE5 prototypes with Lumen, Nanite and water sim. Idk why actual full games opt out of using these systems. Are they just too buggy at scale or impossible to optimize?

[@ArchieDuncan-e3g]

Imagine if war thunder had this

[@MCRaptok]

I wonder if you could modify this to work as an atmosphere for space games. I also wonder if he’s working on a system for water pressure at depths. If so it wouldn’t be far fetched to see it become more than just a fluid sim but an atmospheric simulation too. Extremely cool stuff, keep up the amazing work 🫡

[@livehr4136]

hydrophobia prophecy: "hold my beer son!"

[@notthemessiah9243]

The possibilities are endless. You could have a town that is behind a dam and break it if you want and then the things in the town get washed away randomly so when you try to find them they are always in a different place with each play through perhaps even buried

[@MaxskiSynths]

A disaster game where you actually have to escape a non scripted event would be soooo good..

[@skorne7682]

Whoever came up with the algorithm and GPU compute code to run this this fast in real time is a genius.

[@denischen8196]

Does the fluid simulate less accurately the farther away you are from it, or when you are not looking at it? Can't wait to see the first ever 3D fluid physics puzzle game!

[@thegreywanderer8427]

This simulation would be fantastic to have in survival games where people can build dams, dig the ground and alter the rock surfaces too.

[@mikedytham9996]

It's amazing to think that we've moved from 8-bit 2d sprites in Space Invaders to this. Makes you wonder where we will be in another 10 years.

[@skiptoacceptancemdarlin]

The water is pushing the turbine without even touching it. TECHNOLOGY!

[@arnaudmorel8369]

In slow motion, at the beginning of the video, it was look like 10 yo effect, once you put the video on realtime it seems real, good work !

[@stoched]

Not sure how performant it is in the context of a full game with a lot of other stuff going on at the same time but it would be sick if the new Subnautica had this haha

[@alan83251]

This is really cool. Keen Software is trying to do something similar for Space Engineers 2. Fun times ahead!

[@Pandarah]

Every time I see an update on this simulation, I'm left in awe. I just can't believe that this is real time, yet I'm watching it happen!

[@GTChris]

Can't wait for a developer using this to make a game where you explore the ocean in this engine.

[@andresilvasophisma]

It's impressive but there are some things that look weird. For instance at 4:42 if you look at the outlines of the water against the background (rocks) you can see that the lines themselves are static, it doesn't move like water at all. I hope they improve on this because it has potential but it still looks a bit uncanny valley.
