GWater2 - Emitters, Drains, and Evaporation

[@Snowsuke]

@@lunarlight69 Right now in 0.5b You can use gravity gun with gwater2. Use blood preset and turn the particle scale down to 0.1 for realistic blood. Using gravity gun and pick the blood from the ground, It slowly form a sphere. It's just like Choso's Blood arts But Realistic style. So cool.

[@SasquatchOni]

When you turned the water to the red goo at 1:40, I just can’t believe what I’m seeing dude lol. This is so cool to watch come to life over and over again.

There's a reason the scrubs aren't using particle physics if we're talking performance. I think people will understand. This is fucking awesome!

[@sitkinator]

I did not even think of the crazy wallpapers people would do with this addon. They'll pose and compose the characters as usual, but then will just play around with GWater to do some sick liquid background. I imagine it would have to be a separate pass and maybe it'd require some good editing on Photoshop to get stuff like the light going through the liquid, but with enough skill, it'd look freaking amazing.

[@Meetric1]

it'll be especially hard with all the lighting stuff water has to do, just putting it in front of a green screen probably isnt going to cut it

[@olegmoki]

​​@@Meetric1 i think you can put in on a black background and then use "Screen" overlay mode in an editor, so it only shows water while leaving black transparent, and i hope i understand it correctly. But yeah it would still took some editing to make the light bending or something

[@R_Williams_Gaming]

[@bdura2021]

wator Evaporation is an AMAZING feature (drains too!)

[@ceptemzorpus]

this is really cool it's like the most accessible water simulation software

[@goldfishglory]

I love the laminar flow that happens

[@Khal1337time]

tbh with the way the water is simulated its much easier to acheive, but it still looks great. (exp: basically the particles in actual water being smaller than the gwater particles is what makes it easier, due to the amount of manipulations required to make particles of gwater's size look like actual water (it does a very good job of this))

[@goldfishglory]

@@Khal1337time yeah that and the water shader makes everything blob together. in real life disturbing something like that would completely ruin it but with this the flow would eventually just get back together without that choppiness you get

[@CringineerGaming]

In regards to performance, don't worry about how well things run right after you integrate them. Everything starts out rough, and over time you fix the kinks with it. Thank you from the bottom of my heart for putting in the time and effort to add water physics to Garry's mod. I really can't explain just how thankful I am. I understand how difficult it must be to deal with everything this project has to offer, from people to code to finances. Just keep doing what you are doing and don't be discouraged when something out of the ordinary happens, you have an entire community here to help you : )

somebody needs to make a blood mod using gwater as soon as possible that would actually be so awesome i can't wait for this to come out cause i really want to see the final product if this is how awesome it looks just in 0.5b!

Finally! A working bathtub for me and my pleasure! Can't wait to build my own apartament in Southside with water!

Probably brought up before but that grass texture is likely ruining the bitrate of your videos. It's why the gm_construct previews look better. Also 1:42 World of Goo

[@Meetric1]

oh huh, good point. Thanks for the insight

[@DitieBun]

looks so sick so far and I'm glad you added a lifetime modifier, would probably take a huge amount of performance otherwise all it needs now would be some sounds for when the water is moving around and hitting stuff

[@jackman6625]

It never fails I get more shocked with each update.

[@robooz]

If Valve ever makes a Portal 3 they have to ring you up for the gel physics

[@MajatekYT]

This is just getting cooler and cooler. If you're accepting feature suggestions, maybe a colour variance slider would be a nice small addition? That way water or blood can have varying murky colours to it which would make it even more realistic. I saw that you can have multiple different coloured fluids simultaneously, so I think it could work.

[@Meetric1]

it was removed cus implementing color mixing is a notoriously difficult problem to solve efficiently

[@MajatekYT]

@@Meetric1 Oh damn, well it's good to know! What you've made already is simply phenomenal. Fluid simulation is difficult as it is, and you've managed to make it have two-way coupling with a whole game and physics engine from 20 years ago. That's more than an achievement on its own!

[@mtndewv]

[@stanley8006]

That description is… depressing. I really sincerely hope you find the luck and support necessary for this -mod- incredibly impressive fluid simulation to be finished (Don’t read if you think this is dumb, but a shitty fix to particle lifetimes performance hit is to revert back to no particle lifetime and instead delete any particles that go too far away their spawner entity, like a distance check or smth)

damn, literally 10 years ago I was fiddling with source's in-game particle system with fancy water shaders and thought that was amazing physics, and made a little map with a fountain like the one at 0:05 and but this time the water is the real deal

[@ybeeqs]

Amazing work as always boss man ❤🔥

[@roberthunter6122]

Damn lmao, looks amazing! Now we just need it to have an option like- evaporation effect, leaving a damp spot where it evaporated, and then that spot fades away. Then realistic.

amazing work

[@AssailantLF]

In response to the description: Idk how feasible or convoluted this is, but maybe you could include an option to disable particle lifetimes in order to improve performance from particle generation. It lets the user make the decision for themselves to play with fire, and technically no one could say 0.5+ is slower than the older versions at that point

[@Meetric1]

ehh.. feels kind of hacky. I'm just going to keep attacking an async particle creation solution. I nearly have one, but it comes with some major visual bugs

laminar flow in gmod is crazy

[@lordmarum]

The blood vortex looks so impressive! Question about the technical talk. Why did you decide to use decreasing timers for each particle? Does storing a birth time or a death time to compare a single changing global timer not allow for some of the features? Thank you!

[@Meetric1]

by storing a birth time, you lose the ability to have different lifetimes per particle (maybe you want some particles to never despawn, or vise versa). You also need to make another buffer to store the invalidated particle data, which comes for free with the decreasing timer approach, since all particles with a lifetime less than or equal to 0 can be considered invalid edit: just reread the comment (oops), and yes a death time would also effectively be the same thing, however using curtime as something to base your timings on is a bad idea, since eventually you can run into precision issues. In this context, this isn't necessarily a problem, especially with gmod servers needing to restart every day or so, but I think the approach is cleaner regardless editedit: (death times arent always a bad idea, but in this case they can produce undesired results)

[@lordmarum]

[@alecz3843]

Instead of subtracting the particles lifetime every tick are you able to set lifetime to the current tick + how many ticks its life time is so that you would only need to check if that variable is

[@pimentinhagames7248]

fun fact: evaporation is exponential, meaning the less water there is, the faster it evaporates.

[@inkoalawetrust]

Reading the description. Maybe you could have a separate version of GWater2 without these really expensive features that bog down performance?

[@Meetric1]

at that point the mod wouldn't have anything fun

[@inkoalawetrust]

@@Meetric1 Well, I meant more the timer, but like yeah, that's also what having separate versions would be for, one has less features but supports a lot more particles and such.
