Realflow Liquid ABC: P (Part 1) - Riverbed simulation
For this video I'm providing a riverbed-geomtry that I've modelled in Houdini which will hopefully give some nice natural details as we set up the simulation (available for free through my Patreon-page, link below). In this first part we'll import the collider and set up the simulation, I'll also talk a bit about finding the sweet spot for how many threads to use when simulating with Hybrido and also cover some basic meshing and the initial setups for splash, foam and bubbles.
The plan for the upcoming parts is to assemble the scene in Blender and render using Cycles.

This ambient, moody environment under the bridge-scene right here is my first venture in @UnrealEngine What a time to be alive, and the almost most crazy part is being able to drag an asset into the scene, the material is assigned and setup, the TEXTURES are assigned to the material, if 15ys-ago myself had had this who knows what I would have made.

Wow. This is seriously helpful. Thank you
What about the Macro Deamon, do you think it works well? Because I haven't seemed a single exemple over the web which looks nice. That would be an interesting topic.
wrong workflow...
What did you use to make the mesh? tnkx
Realflows VDB-mesher ✌
@@Davesplaining and velocity color??
Wow thank you!!! Explained a lot of about proceduralism.
Please do part 2 🥺🥺🥺
THAAANNKSSSSSSSSS
You're very welcome!
awesome Mr..Dave...than k you for Great tutorial
Appreciate it!
@@Davesplaining and splash, fom with dyverso??? tnxs
thank You so Much
Thanks for the kind words!
I saw this channel and was very surprised because when I searched for RealFlow tutorials there weren't any, it looked very few, but here there are lots of things I can learn! Thank you!
a better shape for the force field faloff would be a Cone that's wider at the top and tapers to the bottom . . and it would be even better with some fluctuating noise and some ammount of animated scaling BUT I don't know if these two are even concidered possibe for force fields in houdini
Est ce sue realflows prux integrer les champs electriques dans ses calcus?
"Désolé, mon français n'est pas excellent. Pouvez-vous préciser ce que vous voulez dire ? À titre d'information, je n'ai pas utilisé RealFlow dans ce projet."
Tres sympa👍👍👍👍👍👍👍👍👍👍 Vremant cool
Merci beaucoup!
Top👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Merci! 😇
This will be a performance disaster if you have a complex scene with a lot of materials. Keep the material creation and assignment as far down the chain as possible. Cached materials notwithstanding.
Hey thanks for commenting - do i understand you correctly you're not objecting to using fewer material libraries - but I should have them after lights etc? As you point out, this workflow idea does not come from experience working with complex scenes, so appreciate the input. Also - any goot tuts you would recommend?
You are back! 🥳
Excellent 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍 Thx lot
This is brilliant, thanks
Why aren´t you doing it in Houdini ?
My channel started as a realflow channel and the majority of the audience still use RF. Will keep providing RF content but do more and more houdini too.
Hello! I'm on the verge of diving into liquid simulations and am currently deciding between RealFlow and Houdini, as far as I understand my options at this stage. I'm aware that RealFlow might seem rudimentary when compared to Houdini, akin to comparing Tetris to a full-fledged computer. However, when it comes to liquid simulations specifically, is RealFlow capable of performing the tasks that Houdini can? What would be your recommendation?
Looking forward to the next one :)
Can you render sea foam, splashes and water all at once?
Yeah you can. Although you might want to render them in separate layers. In order to have individual control of them in comp.
Hey Dave, I tried to reach you on instagrams but unfortunately it says you can’t receive msgs I follow your real flow videos on UA-cam a lot, am vfx artist/comp artist been using real flow and have had it for years now, iv done quiet a few things until lately decided to fully go into it, with the help of your videos iv been able to understand hybrido system as there aren’t many video on it especially on rendering particles which is why i wanted to reach you because am having few issues, Firstly I can’t seem to get the displacements baked on hybrido mesh even though I had it enabled on hybrido to always and cached it, and even even though I enable it on the mesh to use displacements it’s not really working iv tried every possible thing, would you know any fix for this? Another issue am having is when I enable open boundaries, it’s cutting some of the mesh in the middle especially if am making something emerg from the water like a ship or object though the hybrido square is set to exact size of the mesh and not cropping everything but it crops anyway… can I have your email so that I forward you some screen shots or something but first have you every run into the displacements problem before?
Excellent 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Merci Sam 🤩
Great tut! For more complex objects, how do I get it to really stick more evenly across objects so it shows more of their shape
looks awesome!
Joli👍👍👍👍 Un petit peut statique , mais 👍👍👍🖖

I would love to see a sheeter tutorial, or just more videos like this! Thanks
Thank you Dave. Pretty simple to follow and great explanation
Appreciate it, thank you.

Thanks bro
Very cool stuff.
Glad you think so! Thanks
Excellent 👍👍👍👍👍👍👍👍👍👍 Its verty good to sée a New tuto
amazing content. thank you
glad you like it! :)
can i achieve this using bifrost alone? i want to have a 3d object come out of the sea. The sea is a real video footage shot by a camera. I want to place a 3d object so that it comes out of the sea and so creates some foam and some splash effect as it comes out. Like the ones you see space ship coming out of the sea.
This is a great tutorial! Do know how one would do this in cinema 4d with Realflow? i am trying to make a scene where someone comes out of a pool of still milk.
Hello there. Glad you like it. I haven't used any of the plug-ins for Maya cinema max etc but AFAIK they don't include hybrido, so you'd be stuck with dyverso which could work if it's not too big but you won't have secondaries as readily available. Check my crash course for a similar setup, in standalone however.

Stupid tutorial
What seems to be the problem?
Hi Dave! Fantastic tutorials all round. As a beginner you are the best Teacher I can find out there. Just wondering do you know about maya 2022 and RF connect? Cause I can’t seem to get it working or even loading
Hi Bryan, Thanks for the kind words, it means a lot. Looking at RF support site it seems they're finally saying officially that the plugins are no longer actively developed. That shouldn't stop you though, there are ways to get your sim into maya anyway. May I ask which renderer you are using? I might have some ideas depending...
@@Davesplaining hi dave, thanks for the reply. I have emailed you instead :)
So incredibly useful! Thank you Dave!!! What was your rig looking like when you made this video? GPU, CPU?
