Intro to FLIP Fluids - Part 1: Getting Started [Blender Add-on Tutorial]

[@NickAcevedomusic]

Just started blender 3 weeks ago and flip fluid is tremendous. PS This also might be the most clear, concise and approachable tutorial I've ever taken, and I've watched probably hundreds at this point. Excellent work

[@saintjames9]

this was such a clean, efficient, comprehensive tutorial. instant sub.

[@PixelPlanetStudios]

Awesome, thank you for the sub! 🚀

[@MysteryFinery]

@@PixelPlanetStudios i made a large barrel with a hole and the water never comes out, what should I do?

[@PixelPlanetStudios]

I literally did a sim like this recently. Depending on your final look, what I did was avoid filling the barrel at all but rather add a flow object in the hole. Does that make sense? This is a setup I’m working on for an advanced flip fluid tutorial.

[@ianmcglasham]

[@Joeherman]

Thank you very much for the great video. I am noticing that the speed of your simulation is much faster than my system. I have a 3090 graphics card and a nice intel chip. Is there a switch you have to enable to get things running as fast as you? Is the graphics card used to calculate the sims? Thank you!

[@PixelPlanetStudios]

Hello and thank you for watching. This is a very common question and firstly I have increased the playback of my sim sections to make this more watchable. In the future I will call this out or leave it real time. As far as your rig. The simulation of this add-on doesn’t utilize the GPU (hopefully it will in the future). So the speed of your sim is based on your cpu. From my experience, both Windows and Mac run quickly with newer hardware. I hope this helps 🚀

[@Joeherman]

@@PixelPlanetStudios Thanks. That makes sense. You might want to mention it so that people don’t think you are on a supercomputer, however speeding up sims is a pretty common thing so I suppose I should have realized it. At least you’ll stop everyone from asking you.

[@alejandrovallejo4330]

I’m curious if you can simulate a planet’s orbit or simulate a ring of water orbiting a planet just with the gravity and speed settings

[@efayetang278]

Love your video! But is there any way that I could possibly remove the watermark from the addon? Or is there any other free addon that I can download?

[@PixelPlanetStudios]

Hi! For this add-on you’ll need to purchase to remove the watermark. But blender has some built in fluid tools as well. 🚀

[@emmanm5633]

[@juannicolasreyesrestrepo2070]

Hi man great tutorial! Very well explained! If you dont mind me asking what are your pc specs? since the baking its way solower i want to compare times! Would appreciate it!

[@PixelPlanetStudios]

I am using a M1 Max laptop to record these tutorials. Keep a look at the render time stat in the side window for an accurate sim time because I’ve sped up the sim playback for the of the tutorial. Thanks for watching! 🚀

[@AdirSousa-zr7lj]

Hey, I'm having a problem... I'm trying to make a bottle pouring beer on a glass, but the fluid is going through the object, but when ''inverse'' is enabled, there is nothing happening on the simulation. I'm using blender 4.1, resolution of 128. When you put a simple object like a cube, it works fine, but with the glass it don't.

[@YOXSXEF]

I'm new but I think you might need to scale the domain

[@YOXSXEF]

I'm new but I think you should scale the domain to fit only the glass

[@cabbshills5732]

Exact same issue here, have done what the other two comments on yours here recommend and it makes no difference. Inversing removes any fluid sim completely and does nothing. Unchecked the fluid does sim but completely ignores the interior of the glass/bottle and only reacts to the domain and exterior of the object. Did you find any solutions?

[@AdirSousa-zr7lj]

@@cabbshills5732 yeah... that's kinda sad... I think that it just can't do that no matter what.

[@MrVitaDani]

How are you getting the bake to look so clean and fluid (no pun lol). Mine almost looks like a stutter compared to that

[@PixelPlanetStudios]

For the clean look it could be one or two factors. Resolution adds more detail but depending on the settings you have now, making it higher might just have diminishing returns. The other factor is your modifier stack, which I like to use after simulating. So here are things I like to do: 1) Remesh plus shade smooth. Use a low voxel unit until you reach the quality you need 2) Add smooth 3) Smooth again perhaps. I hope this helps and thanks for watching!

[@nosirve9458]

what pc do u have? XD it runs so smoothly

[@blenderbeachwavesblend]

From the looks of creating certain simulation of fluid effects, the addon isn't free to use, it has some restriction. I'm just looking for something for 2.92

[@akemi8335]

where can i find the BackLight texture that u used?

[@PixelPlanetStudios]

It’s from Video Copilot www.videocopilot.net/products/element2/#backlight

[@migloje]

I just keep watching all the fluid simulations but no one, literaly no one shows how to settle down fluids in the simulation, i did alot of simulations but fluid just keeps vobling to infinity, triead alot of setting flip value to 0, diferent viscosities, gravity, high resolution, smoothness etc. but it just don't work, inflow stops but water keeps moving for ages no matter what. Maby you have and idea or tips how to stop fluid to move in the end of simulation.

[@PixelPlanetStudios]

I’m working on a video that addresses this exact thing. Planning to post next week. Stay tuned!

How can I export foam to UE5? I've tried, but it's really difficult and I haven't succeeded.

[@pellebonink8116]

Hi, when I try baking the video instead of getting a fluid I get the flip fluid logo. is it because im using the demo?

[@PixelPlanetStudios]

I believe so

[@maksoz_mtb2924]

can we export foam alembic for other softwares ?

[@PixelPlanetStudios]

According to the Flip Fluids wiki this is a tricky option. They say, "A common problem with exporting FLIP Fluids whitewater meshes is that some third-party softwares cannot import this data properly. The Blender Alembic exporter does not support exporting particles or instances, so whitewater simulation meshes are structured as vertex-only meshes where each vertex represents the position of a whitewater particle. Some softwares do not recognize vertex-only meshes as valid geometry."

thanks dear

[@jasonrobinson834]

When I hit object volume the liquid mesh will not bake anymore is there a fix for this ? i am creating a glass bottle with fluid inside but cant seem to keep it contained inside no matter what i try.

[@PixelPlanetStudios]

I’m 90% positive that the object volume needs to be a closed shape. So a bottle with an opening won’t work but a closed sphere will. Depending on the action you are creating, you could close the top of the bottle in edit mode and re-sim. Let me know if this helps! 🚀

What processor are you using? Your fluid sim is impressive since this doesn't run on the GPU. I have 38cores, 76 threads, I thought my sims would be faster. :(

Great tutorial! A little piece of feedback on teaching - you moved a tad fast for a first year learner here and skipped thru vocal propts of what you were doing a lot of times. Other than that, great content, great creative and videos is flawlessly edited. Thank you so much for this video!

[@PixelPlanetStudios]

Thank you for the feedback. I will try to improve moving forward. As a new tutorial creator, I appreciate your notes. Cheers and thank you for watching!

[@cabbshills5732]

Is it a bug but this plugin works untill the point of it only colliding with the container and anything in it. The minute you for example have a bottle in the container and set it to inverse... theres no fluid sim. It sims nothing. Unchecking inverse it then sims liquid but colliding with the outside of the "bottle" so technically cant fill a glass or bottle. Is this a 4.1 issue? I have followed your tutorial exact at 7:56 and clicking inverse on the bottle I am trying to fill does nothing, no fluid sim at all. Unchecking inverse on the bottle I am trying to fill then shows a fluid sim which is just ignoring the bottle all together except for the exterior of it. The liquid falls out the bottom and swishes around the domain colliding with the exterior of the bottle. I have tried both making a bottle from scratch and using a model I wish to use in fbx format. The same issue with clicking inverse happens on both.

[@peterjoslyn1]

The issue I'm having is at a very low simulation setting of 30, it still takes hours to bake anything, and I have a pretty good CPU (AMD Ryzen 7 5800X 8 core with 32 GB of RAM) - is there anyway to speed the process up?

[@PixelPlanetStudios]

Hi! From my experience, the best way to speed things up are to lower the resolution, make sure your domain is as small as it can be, and reducing the geometry of any simulated meshes.

[@skib1digyat]

Out of curiosity, why does the sim rely on CPU's and not GPUs?

[@hoonlee2492]

hey bro particle is not shown in my octane render could help me? :) i can see particle in first frame but other frame is not shown,,,,,,,in render view X(

[@PixelPlanetStudios]

Hey, thanks for the question. I’m looking into this now.

[@PixelPlanetStudios]

I did some tests with particle rendering and octane for Blender. I had to use the 'render image' window to see the final result, and it wouldn't work for me in the live preview rendering inside the viewport. If that doesn't work for you here are some ideas: 1) Make sure the particles are simulated and are appearing in the viewport (non-render view) as points in space. 2) You mentioned they are disappearing after the first frame, so that might be a simulation error with the whitewater settings or fluid movement (hard to say). 3) Increase the particle size in the fluid settings of the bubble, dust, foam or spray items. Let me know if this helps.

[@hoonlee2492]

@@PixelPlanetStudios Thank you. But it didn't work out. Perhaps the render engine needs to use cycles to make accurate simulation possible. Particle simulation doesn't seem to be applied in Octane Render.

[@PixelPlanetStudios]

One idea: Under the inflow object, you may want you click “Force Re-Export On Next Bake” in the mesh data export section. Perhaps the data isn’t being updated. OR if you haven’t already, be sure to check “export animated data”. Does that help?

how can I delete de water that goes through the domain? I don't want the domain to act as an obstacle.

Is is possible to turn the simulation into an animated mesh with shapekeys or export it out as alembic?

Yes, you can export it out as an alembic mesh. Select the fluid surface > Export as Alembic and make sure to select 'Only Selected Objects'. Thanks for watching and I'm sorry for the slow response. Cheers!
