Guest Tutorial: Meshing Small Scale Flip Sims

Our friend Alvaro Moreira / alvaro.vfx.skull put quite a lot of work in optimizing small scale fluid meshes over the last couple of months. Today he wants to share his findings with the Entagma community. Watch him smooth a fluid's surface while maintaining sharp creases between the parts of this viscous fluid.

I deeply appreciate all the work you guys put into these tutorials in these troubling times.

[@cihankenar1]

Yes the dark ages were quite tough.

[@GreasyBirb]

Great tutorial. Honestly the thing that blew my mind the most was that you can select two nodes and use ALT to auto-merge them together. You've probably shaved off literally minutes of my day putting down merge nodes.

[@mjparent222]

Well Thank you so much. You go through the steps in a very understandable way ! Really good tutorial. Continue for more interesting and creative stuff.

[@krip.gadgets1481]

this pearl poo just convinced me to install Houdini at last. You guys are amazing.

[@aboldmule]

Exactly what I was looking for to do a syrup sim. Thank you!

[@oleit3]

Alvaro representando! Aí simmm :D Thanks for bringing us this amazing content, Entagma!

[@ParticleSkull]

Thx Gabriel!!

[@lveronese]

particleskull + entagma = very big smile

[@workflowinmind]

Same here

[@ParticleSkull]

Thx Luca, my smile is even bigger ;)

@@ParticleSkull Yaman! now tell us how to throw the eyeballs on it! ;P

[@ParticleSkull]

@@AC-bc9kn Hey AC, its actually not that complex. I basically scatter the eyes on the fluid's mesh, frozen on this last frame. Then I use a point deform connected to the simulated particles to make it move

[@neptun3189]

this was fantastic, cant believe how much i got from just 25minutes

[@Djoshua1000]

Thank you for the lesson. one question - how to write the last stage of smoothing (using the blur attribute) in alembic? because the alembic itself is preserved without smoothing

[@jippiiiiiiii]

Hi! Very good tutorial. I'm trying to export alembic but the attribblur is not working on that and it makes the mesh look really bad. In houdini it looks really good though.

[@pavelkhorenyan7117]

Good one! I did similar sim (toothpaste simulation, it's in my videos) but couldn't get it to work through flip solver. So I had to figure out a workaround.

[@yamoogeada]

Thank you for the great tutorial. ^^

[@evmlionel]

thanks Alvaro! can't wait for more (:

[@ParticleSkull]

glad you like it, Rynorigami ;)

[@pdjinne65]

Super useful tutorial, you're a pro! Thank you.

[@Yakoza09]

Man i do really like what you do and thx that you are trying to help us to improve in Houdini!!! BTW it doesn't look like chocolate :D

[@STROBdotNET]

Hi particle skull!! Thank you for those amazing tips! Q: why don't choose "vdb from particle fluid" instead of "vdb from particle", what the difference?

[@francescomatera2904]

Thanks so much for the tutorial! I'm a newbie with houdini and I don't understand why you prefer to build the whole structure of nodes instead of using the Particle Fluids shelf tab. Is there any reason for this?

[@kimnaye473]

Thank you for the great tutorial. How can I resize the parameters panel like in your interface ?

[@kimnaye473]

Never mind. Found it :)

[@paulvansommeren]

I wish all tutorial (in general) had those first 2 minutes of a walk-through...

[@Ep19MA]

Very good tutorial, looking forward to beer simulation tutorial

[@massimobaita7178]

Thank You very much!

[@PostolPost]

sorry, what do you press at 16:50 to see the particles instead of the form? Cant hear, "Press Tab" ,"Press double"? Don't works for me..

[@ParticleSkull]

hey Postol, the shortcut for the front view is 3 (while the cursor is on the viewport). Not sure what I said, it looks like I said tab for no reason

[@PostolPost]

@@ParticleSkull thank you,

[@sams_3d_stuff]

Thank you so much!!

[@jordanstark2996]

Hey, I got a question. How do I render this out with a simple shader using mantra?

[@HobbitVFX]

is it possible that I can export this to blender using the apprentice version? Thanks for the tutorial

[@izvarzone]

only in obj format, no animation

[@juancarlosgzrz]

How can I do to make flip stop emitting fluid?

[@k1qu344]

Anyone knows why whenever i go under .01 on particle separation my sim stops being viscous? any value under .01 breaks the sim

[@roberthintz4017]

Can you do requests?

[@Entagma]

Open for suggestions, but no guarantees on requests :) Cheers, Mo

[@roberthintz4017]

@@Entagma How about scales for a suggestion?

[@Entagma]

Scales like in fish scales?

[@roberthintz4017]

@@Entagma Scales like in lizard scales.

[@grebenshyo]

@@roberthintz4017 do a 'points from volume' set to tetrahedral to your surface and copy your scale onto those. this here is a neat collection of tips for copying geo to points: kzbin.info/www/bejne/jX7JeZiFg5yUsNk (a bit oldish workflow, actually, but it's fine for understanding the concepts. after that you might wanna check out the 'copy to points' node instead of 'copy stamp')

[@giovannicaianiello7669]

beautiful your very professional tutorials, could you do a tutorial where you create a dense fluid choccolate on a small bar? it would be fantastic thank you very much for your videos always 10000K like :-D

[@WhimsiLooml1118]

nice video could you make a tuto about toothpaste

[@STROBdotNET]

There is naother tutorial with the same kind of technique and some more: vimeo.com/409698465

[@TroubleShotVFX]

You are copying an pasting code into things before I can even process what you did.

[@Entagma]

Hey Dan, thanks so much for your feedback - it helps us to constantly improve our channel. Cheers, Mo

[@AerysBat]

Great FLIP tutorial, these are hard to come by!
