Silly Pillow Pt. 1: Setting Up Stitches In Vellum

Support us on Patreon: / entagma
Mo needed something relaxing after a longer stretch of math, algorithms and OpenCL. So we decided to build something quick, rewarding and fun: A weird inflatable structure in Vellum.

Insane as always the best Houdini tutorials out there. Thank you

[@user-hl5zx1qh7s]

ok i will be fan of Entagma from now on

[@adamglass2599]

I had some mixed results with my initial attempt doing this via fuse for the base pillow. I went back and reproed your results with your method, added a switch-if node and put my fuse construction as the other input. The results are similar though the geometry in the fused case is more tortured around the edges which might have implications for texturing/rendering without remediation.

Simple & Elegant

Really love your work. Thank you. Would it be possible to pull in curves from another software like illustrator? Say for nstance I wanted to make a specific piece of clothing with unique patterns?

[@filipvabrousek6900]

Amazing tutorial thanks!

[@NabilJabour]

Great tutorial :) thanks!

[@AdrianoZanetti]

Great stuff! Thank you. Quick question please, I'm using an animated noise for the welded points groups, how do i force the vellum solver to update those groups at each new iteration / frame please? I was hoping to find a "match animation" type of option in the Vellumweld node but there is none in there. Can this be achieved with a sop solver within the vellum solver node perhaps? If yes, how please? Cheers.

Hello! How would you go about getting ropes to physically tie up the shape, instead of setting up internal lines?

[@Misstigon]

Thanks for your tutorial. Please post Pt. 2

[@Entagma]

Thanks for reminding me. Almost forgot. It's gonna be released on Monday. Cheers, Mo

[@workflowinmind]

Very cool, I always wondered about scale best practices in Vellum & FLIP. Is there a reason your 10m sheet looks like a 10cm one on the simulation? Is there a 10x factor I did not know about? How do you go about scale yourself? Thanks

[@manuelst3004]

Hi Mo. Thanks for this tutorial. Great content as usual! One thing that I noticed is that, if I move my grid away from y=0 my sim behaves in a very weird manner. Do you have any insights on why this might be happening? Cheers!

[@check99999999999]

Thank You Mo, I'm wondering something : so here you are working on a pillow measuring 10 metres on 10 metres : That wouldn't be the logic size to working on for a real pillow ? (But it-s probably a stupid question as the simulation works fine in the end, and it's all we need.)

[@globglob3d]

Does someone know why if you translate the whole pillow on Z by a few cm before simulating it goes flying really high? It's messing up the sim badly for some reason. I tried to center the pivot with $CEX, $CEY, $CEZ, but it didn't work.

[@joe-rivera]

Exclamation point in group name: 🤯 Oh, the time I’ve wasted with the group combine node for this same effect!

[@tempermode]

For some reason I couldn't get the Vellum Weld to stitch the points together. However, I used a Fuse node after the merge and it worked fine from there. Just in case someone runs into the same problem.

[@workflowinmind]

The vellum weld does not fuse anything, the vellum post-process has the option to.

[@bhaskarvfx1602]

Thank you for the great tutorial, Entagma, please take topic of Bean Bag with stitching, tutorial ? thanks

[@Digital_Guerrero]

Great tutorial, thank you!. Can anyone point me in the right direction if I want to use a black and white image for point selection for the welding groups?

[@Entagma]

Hey Matt, use an attribute from map SOP to load your image onto the grid, then use a group expression node, set to point grouping with this in it's VEXpression-slot: avg(v@Cd) > 0.5 This selects points on which the image brightness is above 0.5. Cheers, Mo

[@Digital_Guerrero]

@@Entagma worked like a charm. Thank you!

[@JanTrybus]

why my pillow is flying away at the end of the simulation?

[@notimportantstudio]

Hey @entagma since I downloaded one of your files and opened it in Houdini mu UI is super small. When I try to reset it our change it in the settings of Houdini nothing changes., Restarting Houdini or the computer doesn't help. Its on my laptop and now its just not workable I need to press my face against the screen to read anything. Any tips?

[@Entagma]

Try deleting the respective Houdini folder in your documents, that should force it to recreate all settings from scratch, maybe this works. Cheers, Mo

[@notimportantstudio]

@@Entagma Hey Mo, thanks I figured it out in the end :)

[@smaugthewyrm]

possible to post the hip? i’d like to see the shader.

[@Entagma]

Heyhey, we're gonna publish a shaded .hip once we cover the shading of this. Which is gonna be in part four. Cheers, Mo

[@donaldjrtrumpy8511]

Mo will you ever post something like destruction or flames ? just for research purposes

[@Entagma]

Hm, I guess never say never - but those topics are definitely not my cup of tea. Cheers, Mo

[@ahmadq9195]

wow

[@rafayetnewaz]

Let me start by saying that i love you guys but what's up with the highly saturated voice? It's really annoying. Please don't continue with this voice chain if possible..❤️❤️

[@Entagma]

Hmmm. Listened to this setup on a range of headphones (crappy to studio monitors) and even a few cell phone speakers - this was the best compromise to our ears. What would you suggest doing differently instead? Cheers, Mo

[@rafayetnewaz]

@@Entagma The sound before the last 3/4 videos were absolutely fine. Not great may be but better than most. I would recommend a soft compressor first, something like teletronix 2a emulations. Then a High pass filter somewhere between 150-200hz(approx.) Then another hard compression. Then De-essing. Then some EQ to brighten it or to shape it. And a little saturation/distortion if you like(it will be better if you do the saturation parallelly). Right now, there is too much saturation in the sound. Too much sibilance, probably accentuated because of the saturation. Somehow, I feel like you EQ out the lower end of the voice and brought it back forcefully later with some other processor. Overall, the sound is very Mid heavy and has a lot of lower end artifacts. In my opinion older sounds only needed a bit of compression and brightening. That’s it. Thanks for the consideration though. Cheers... 😊

[@rafayetnewaz]

@@Entagma Oh forgot to mention, Great tutorial as always..👍

[@Entagma]

@@rafayetnewaz Nice, thanks so much! All I've got here is a dbx 286s channel strip, might dial back the compressor's ratio and the equalizer's low end, de-esser is already in there and of course a gate... Cheers, Mo
