gfycat.comI'm working in UE4 with Flex integration, the water emitters are a lot of fun to play with. I can render about 500,000 particles on my system (2500k, 970) before the physics simulation noticeably slows down, in the gif the emitters stop at 20,000 particles.

are these columetric with persistence? could i run actual waterfall style thing with those particles?

What are some games that use this engine? Sorry out of the loop.

How did things go from UE3 being the most popular middleware of last gen to UE4 being hardly even used by big developers?

UE4 is new and hasn't had time to become a standard. It's also pretty hardware intensive.

It's been more than two years since the current gen consoles have been released. It was right around this time that UE3 had become the go-to middleware for developers. I doubt that's going to happen with UE4 this time around.

while it answers the question, i think you should also mention that most of those games do NOT utilize these water physics.

ty!

Keep in mind, just because a game uses UE4 does not mean it will look this good (or good at all). A ton of crappy looking and playing games use UE4 as its a relatively easy engine to use with a lot of "badge" value. You can plaster all over the games cover/store page "Made with Unreal Engine 4!" and technically be true.

Didn't know that, thank you!

Agreed - The majority of UE4 games I've played recently are subpar. Kind of deters me from enjoying UE4

Is it weird that this makes me want to use UE4 now?

Go for it! There's a ton of tutorials and it's not hard to get started. Also check out r/unrealengine

Just make sure you get up to date tutorials because a lot of features were changed since release.

What am I missing here? This looks like utter shit.

too slimy. That looks more like jizzics than water physics

I don't know how to describe my feelings towards this. I think it is cool, but the water looks... globy?
2
Really cool now what would be even cooler is a map with two towers on a small piece of floating land you see and the towers they need to be close enough so that you can snipe from one tower to the other.
Oh oh and put a red flag in one tower and a blue flag in the other and put zero-gravity.
Imagine how cool that would be!

oO
...just the tip?

I really do hope in the future AMD (GPUOpen) includes their own based water physics with Unreal Engine, so a particle based simulation game can be played on either graphics card or even on a tablet. It is fun to play with the particles, but I just don't see the practical use for it on low end machines, because the amount of processing power needed. I know Borderlands has incorporated
FlexParticles & Fluid, but it would be cool to use this for education at a 1st or 3rd grade level by using a tablet.Edit: I need to look at the demo commentary video later for Borderlands Game works demo, because I forgot about Apex as well as Particles & Fluid system.
Edit edit: yeah it wasn't Flex, it's been about six months since I've used it, so I'll need to look at the documentation again in the future. I'll check out your edit links later.
IIRC Borderlands uses Apex and PhysX but not Flex, Flex is very new. I don't think it's featured in any released games. Epic modified PhysX and Apex to run on the CPU rather than the GPU, so as to be video card agnostic. Maybe they'll do the same when/if they officially support Flex, right now it's just a limited port on github that NVidia maintains.
I haven't looked into tablets or low end machines, but it might run on those eventually. Flex is already a lot faster than PhysX.
Edit: It looks like Borderlands used something called SPH Fluid, which was Apex's way of handling liquid. Very similar to flex particles, I wonder if this kind of thing wasn't the foundation for Flex.
Flex is featured in killing floor 2, it's pretty sweet.
You're right, that looks awesome.
Yup it is. Its also demanding as fuck, as in a 980ti dips below 60 with Flex on in heavy scenes. Considering that the rest of the game looks decent but doesnt even come close to touching a 980ti's power, Flex is demanding. Still its easy to see why, it does looks fantastic.
Although TBH that was when flex was just introduced. It may have improved since then, i'd be surprised if it doesnt improve massively in the future.
Now to add the gravatational forces for the water so we can watch it coalesce back into one big sphere.
