How to make realistic foam in Blender?

Here's how you can make realistic soap foam in Blender, in Patreon you can also see how to make coffee foam, but don't worry, there is no rocket science and once you know how to make soap foam, you'll also be able to figure out the coffee one.

I’ve been looking for a foam tutorial for a really long time, and literally today I realized a project I’ve been working on requires a lot of bubbles, PERFECT TIMING! Thanks!!

[@BadNormals]

I'm happy I helped!

[@JaredOwen]

This was like a suspenseful movie - I'm on the edge of my seat to the very last minute of the video. ...and then finally bam - there it is! I really enjoyed this, thanks for taking the time to make this video.

On the last step, to make it lok really iridescent, i would recommend default cube's approach, which is using a Fresnel connected to a color remp which has rainbow colors, so t he colors change as you look at it from different angles, looks really good

[@rysea9855]

If the main focus of your render is the foam, I'd recommend doing this. Otherwise it'd probably take more render time than the result is worth

[@reverb07]

Damnn this is really good!! I was searching the perfect foam tutorial and here it is!!

[@BlenderMadeEasy]

Wow great work! The foam looks very realistic and it's pretty simple to set up! Thanks!

[@renderize69]

Hey! I know you!

[@purooshresth7809]

Hey whatsup man i made the planet last year because of u i am a subscriber

[@DisAbel]

Honestly, I would have just Ian Huberted it and got an image texture of foam and used a displacement map to get the bubbles then do sum fancy node work to get it too look good

[@billyboy_45]

Yeah just use a sprite + normal map + reflection map and you're done haha

[@Patatifique]

literally did this for a recent project's coffee foam lmao. If it's in the background, no one will notice

[@samkangoo]

Yeah but that's the whole point of this tutorial, make a realistic and procedural foam for xtrm close up shots...

[@_p4n0ptic0n_]

Eyy say hi to Jack Bright for me when you see him next

[@gytiskau1865]

8:04 I would add an xyz separate node between the Voronoi (vec3) and ColorRamp (float) nodes to get actual random values from the Voronoi output, because they are currently averaged into one single float

[@BadNormals]

Thanks for the tip!

[@0dWHOHWb0]

This is a really cool method and very neat result

This is absolutely mind blowing.

[@malik12tree29]

At 10:43 , u can use the smooth minimum, it will make a meta ball effect which makes it as real life bubbles!

[@kingjulian5227]

Respect for doing all of this just to make foam

[@fabiobiffcg4980]

A really good tutorial! One thing maybe could be added is the Fresnel for reflections (Fresnel node multiplied by the bubble mask to the factor on the mix shader)

[@sergeyandreev2599]

Two values gonna fight :D 10:45. Great video bro

[@sansidentifiant]

This tutorial is just a gold mine !

[@LivingParadox87]

I only half understand what is going on here, but after a couple of tries, I was able to replicate this. As a newbie with Blender, I was struggling with the scale factor at first since I didn't realize how I would need to start working at the same default scale of these objects as you to get the same effect. I kept trying to add more math nodes in there to correct the scaling issues but decided that for now, I was just going to make these large-scale objects and transform them down without applying the scale. This is absolutely brilliant though and I will certainly be linking to this channel when I post renders that use this technique. Thank you so much!

[@xDaShaanx]

Finally someone made a tutorial about foam. Thanks a lot. :)

[@michaelcorleone8699]

Thanks man, this is genius! You got a subscriber!

[@abdelhaksidialimebarek8615]

The best foam tutorial so far ! I needed this so badly a few months ago and ended up doing it 2D. It looks like Particles ain't the way to go.

[@tobiasreckinger2212]

It might benefit from using a smooth maximum to bevel the intersection edges between bubbles a tiny bit. I think it might be a little bit more computational intensive than with simple maximum but with such a computational intensive project it shouldn't matter to much

[@W42ny]

This is on my front page almost every time.

[@BadNormals]

And now you clicked.

[@4.0.4]

Holy crap, this is amazing! I wonder if you have any ideas for bread/sponges/etc because those are also extremely hard to get right without Ian Hubert-ing or Photogrammetry.

[@BadNormals]

Bread, what a nice idea actually...

[@mrofnoctonod]

This is a great setup and technique for looking straight down at the foam from an overhead view, but the illusion completely falls apart when I try create a closeup view from the side.

[@anxhelo7383]

this vagon is awesome , sad its so under rated, more people should know about it!

[@thevfxwizard7758]

Great tutorial! I love procedural materials like this. There is something so satisfying about breaking down an object and figuring out how to make it with nodes.

[@BadNormals]

True, they are satisfying indeed

[@ver204]

I don't normally give a thumb up but man! you are a genius! thanks for this amazing tutorial. I gotta understand how nodes are working each other!

[@BadNormals]

Good to hear that!

[@CG_CAKE]

Great Job very talented thanks !

[@Notyourbusinesschap]

Thank you, this is a glorious tutorial!

[@zainmushtaq4347]

as someone who doesn't do 3D, it's crazy how you need soo many nodes and thinking skills to accomplish different real-life textures. This is both encouraging _and_ discouraging for me to learn 3D programs, but i'll get there one day :D

[@BadNormals]

What kind of art do you do?

[@shivendrasinghpawar6282]

This is exactly what i was looking for, Thanks, keep creating more!!

[@royalblues5485]

Wow i was actually really close in the making of this for a project, didn't finish it though, happy to see you've done it

[@JrgenFrderbergTvedt]

Youre such a brilliant guy ! Thank you

[@maglerdon]

What is the unit scale for this scene? I'm trying to follow along in Blender 3.6 with a scene unit scale of 1.0 but none of the values in your video are working. The bubbles are displaced way too far and the adaptive subdivision doesn't work, it creates weird square tiles.

[@Zuneku13]

You could use the math node and use power by the factor of 2 to smooth the 'cone' shape of the voronoi texture and to make it look more spherical.

[@BadNormals]

Forgot the power, although I'm not sure if it should be 0.5 instead of 2? Somebody can find out and tell me

[@Zuneku13]

@@BadNormals It's to the power of 2 :) You're basically squaring the value or multiplying the value with itself.

can you make a tutorial for this in blender 4.0+? the method doesnt seem to work with 4.0

[@psychonauts0]

I've copied this node for node 3 times now thinking that I'm an idiot, but I just feel like something has changed in blender since this came out, or somehow my settings are messed up. Everything looks great up until adding volume, at which point nothing looks correct. It doesn't end up looking milky when I use your values, only if I bump them up to like 5000, and then when I try use the inverted mask and multiply, nothing ends up looking correct. I'm starting to feel like an insane person redoing this over and over. If anyone has any idea what I'm doing wrong, I'd love some advice. Edit: Still looking for how to fix the issue, but if anyone wants a quick botch fix, you can go into your settings for the material and under volume check the "homogeneous" box, then after that multiply your inverted texture by a massive amount... it still doesn't look nearly as good as the video, but it's better than the broken mess I end up with otherwise. Edi 2: The plot thickens... I went out of my way to get the blend file from Bad Normals original project to see if using the current version of blender the file would look correct. It does. However if I import his materials into my blend file they end up looking just as messed up as the ones I created. I'm now convinced there's something wrong with how my project is set up, but I'm not sure what. I wish I could figure that out, because this isn't the first blender tutorial I've followed to the T where stuff ended up looking wrong after the fact.
