10 TIPS to improve your FLIP FLUIDS workflow in BLENDER

[@DerekElliott]

Great tips -- smooth modifier is a lifesaver for sure!

[@faradaysinfinity]

incredibly relevant still!!!! great tips!

[@jeffg4686]

Love the tip on ocean modifier used in combination with FF. Good Stuff. Can't wait for your 'flip ocean' tutorial.

[@nunolopes8263]

Much appreciated guys!! Keep up the awesome work.

[@uncle_hog]

Awesome, never think about ocean+simulation! Great idea! What about quick tips for fracture modifier?

[@Chicle777]

Great tutorial! I little tip back is to use lower screen resolution when demoing so we can see what you are pointing at in the menu and values.

[@Blenderphysics-Videos]

Yes thats true! New videos are recorded at FULL HD 16:9! Thank you!

[@maschlarea5172]

@@Blenderphysics-Videos since I'm running into this problem more frequently and my Eizo Screens are about 15 years old - was that a dual screen setup, ultra wide or what else? 4/8k? I'll have to update soon, so I'd like to make it count. Edit: "just look, dummy!" :-D P.S.: geiles Addon, super präsentiert - habe es seit 2 Std und mir platzt gerade die Birne, naja, manchmal gefällt mir das!

new to blender 2.80, so thanks for the info! +1 ocean+flipfluid tutorial

[@MADAMOTION]

You're made an awesome Job with FF💚

[@thevfxwizard7758]

Is surface tension and sheeting a part of the free version? What all is not included in the Github version?

[@bysantin]

Yes! You guys are awesome! Great work! Was actually working on a text project, now it will go alot quicker.

[@maxwellabudu988]

thanks for this video, but due to how difficult it is to render fluids, is there a way to replace the water flow with objects, let's say flowing cubes?

[@Blenderphysics-Videos]

You can add any modifier on top of the simulated fluid-surface. Try a remesh-modifier as example ;)

[@drinnerd8532]

I don't know if I like the solution to the first problem of just adding a solidify modifier and increasing the thickness just for the very obvious reason that it can ruin the look of your mesh! Plus, I have tried this several times and it did nothing to solve the problem of fluids passing through obstacles on multiple occasions. The only solution that has sort of worked for me was one that one of your representatives suggested to me, which was to fix Non-Manifold meshes by reducing the number of duplicated vertices by selecting the obstacle's vertices, going to "mesh" settings in Edit mode, then "cleanup-merge by distance." This only worked for me about twice, but it's the only thing that's worked, so far. Now I can't get ANY obstacles to work. I love Flip Fluids, but it's starting to be a very frustrating experience.

[@Blenderphysics-Videos]

Hi Drinner, whenever you are in trouble with obstacles - please check the debugtools we are talking about in the video. You could also send your blendfile to us- so we can check it and learn from your scene.

[@j.galvez5594]

Hiperhyped! Really helpful. Waiting for the ocean+flipfluid tutorial

[@morin6661]

Hi, I have fnished a fluid simulation and trying to render it in cycles. I have assigned an ocean material preset. But on rendering, I don't see the foams, bubble etc. Can you please suggest why this might be happening?

[@Blenderphysics-Videos]

Hard to say without taking a look into your file. Would it be possible for you to send your blend to the FLIP Fluids team?

[@morin6661]

@@Blenderphysics-Videos yes, i can share it as soon as possible.

[@WriteFilmEdit]

Thank you so much, this add on has vexed me for so long! It's great if you know how to use it - if not (like me) you're just lost in render times.

[@CodyVibbart]

How would I animate the fluid pouring out of a bottle or jug? The fluid keeps stopping at the opening as if there is a face there blocking it, but there is not. There's not a single tutorial online for this. Every tutorial only shows how to pour water into a container or bowl.

[@Blenderphysics-Videos]

You can send me your file and I check some setting for you :). Please use the flip fluids support email .

[@nathanp.3909]

With the surface tension and sheeting enabled, there are a lot of different values. What are your values set at for tension and sheeting in this video? also does the Scale matter with how the liquid will look?

[@Blenderphysics-Videos]

There is no answer for all scenes. It depends on you scene scaling , animation speed, world scaling . It is often a try and error game. However , customers can download example files from their accounts to learn from :).

[@HyperActive94]

Hi Denis, Why my water is always black/white in the render and not blue like yours? TIA

[@Blenderphysics-Videos]

Hey Ziko Isaac - that sound like you have not attached any material to your fluid surface. Can you check this, please?

[@massivetree7937]

How is 2.8 flip fluids coming along? I've tried using FF in 2.8 but it usually crashes Blender after rendering a few frames.

[@Blenderphysics-Videos]

This is because 2.8 is not avaible in a stable release (its in development). Many crashs has been reported and we have to wait till 2.8 is stable. Than our addon will work with 2.8 ;)

[@massivetree7937]

@@Blenderphysics-Videos That's fine no worries. Just wondered if there was any news on that front. I love the add-on! By the way, can you tell me why even though I enable white water/foam/bubbles that they don't render? I've assigned the preset materials to the appropriate slots in the FF properties?

[@federicagallo3231]

Really useful :) Great add- on! I was just wondering whether in flip fluid there might also be something like the "control" object of the internal fluid engine ... something to attract the fluid towards the mesh ...

[@Blenderphysics-Videos]

Thank you! This is a highly requested feature and on our todo-list. Together with forcefields this will be in development soon!

[@hubiguschti5867]

yess! very valuable, thanks a lot!

[@simonsaysgray]

I wonder what's better: Changing the Simulation-Framerate to get some slow-mo or change the simulation speed. I get "stuttering" particles when I reduce the sim-speed to 0.1 when I follow the tutorials with the water-bubble (shot by projectiles) and the "fluid along path".

[@Blenderphysics-Videos]

Good question. We always recommend to use higher framesrates as this will give you the best quality and maximum flexibility in postproduction. But keep in your mind this will take longer to simulate, render and needs more discspace

[@simonsaysgray]

@@Blenderphysics-Videos In addition I realized that increasing the framerate does change the simulation drastically. I'm not sure how big production do this but for me it's not even worth trying with low-res-sims as the final result will be TOTALLY different when I turn up the voxel density. So even if I like the low-res-motion, nothing guarantees me that my high-res-sim will look at least a little bit similar. This is something I noticed in general when it comes to fluid sims and I wonder if this is just normal and everyone is just iterating until - with a lot of luck - everything looks good. Another thing which really confuses me (and maybe it would be worth to talk about this in a 2nd 10-Tips-Video) why fluids sometimes get created out of nowhere. Here I have a sim with some breaker-obstacles (friction 1.0, sheeting strength scale 1.0) and fluid with some sheeting (surface tension 1.0 / 90%; sheeting strength 0.5, thickness 0.05) and when the majority of the fluid passed my breakers, suddenly some drips get alive and create fluid out of nothing. imgur.com/DfM7sv1 I saw similar behavior several times now and I have no idea where it comes from. It seems lowering the sheeting multiplier on the breakers to e.g. 0.01 seems to help.

[@Blenderphysics-Videos]

@@simonsaysgray That is a "normal" effect and has been explained in the documentation: Sheeting works with adding additional fluids to the simulation to fill-in holes. To avoid this effect deactivate sheeting or animate the strength value. Higher framerates will increase simulation time. Make sure, that all other simulations (rigid bodies iE) used the same frame rate, and also your general blender configurations has the same FPS. If there is any difference you will have different velocities what is natural and logical. Preview´s are made to have a faster playback. If the simulation result is very different to your final simulation you maybe are using a very low preview resolution. You can increase the preview resolution. That should help you. But it will never look the same like the final surface, as it is calculated differently.

[@ashtonfreeman9267]

Hi, I dont have the option for Surface tension and sheeting - is there an update for FLIP Fluids?

[@Blenderphysics-Videos]

You need to download the latest experimental build as this features are at this moment not in the stable release ;)

[@federicagallo3231]

Hi Thanks for this awesome add-on. Currently I'm trying to render a FLIP-Fluid animation with Blendergrid. Is there a way of getting the FLIP Fluid cache to work on a render farm ? Do you know a render farm which supports FLIP fluid add-on? Many thanks in advance :)

[@Blenderphysics-Videos]

Is it possible to make the fluid transform into an object?

[@Blenderphysics-Videos]

Not yet! But it will come with the support for force fields. This is on our todo-list and will take a while to code.

[@cihankenar1]

Does Flip Fluids work with Blender 2.8 and Eevee?

[@Blenderphysics-Videos]

In general yes - but as 2.8 is in development (the code is changing every day) it might crash often.

[@mad7nstinct494]

When will you release the ocean modifier + flip fluid tutorial? I am waiting for so long :/

[@Blenderphysics-Videos]

Oh yes you are right. Im sorry for that delay. Im working on some other videos, too (development/fracture modifier/promotion video) and we are in communication with a RenderFarm that is going to support the FM and FLIP fluids where we investigate a lot of time for. This means it will take some more time to finish other tutorials. Please be patient - it will definitly come!

[@pedroguanches4530]

If surface tension and sheeting are that good why are they not on by default?

[@Blenderphysics-Videos]

Because it will increase simulation times. And it is not recommend for every kind of simulation.
