Explore 10 different Vellum nodes that can be used to set up cloth, hair, grains and soft body simulations in Houdini. Learn about the different types of simulation you can achieve then explore constraints and parameters that give you control over the results. Vellum can be a lot of fun and understanding these nodes will open up new and dynamic possibilities.

    Amazing Tutorial Series Paul, thank you!

  • FridayMarch27th 3 years, 5 months ago  | 

    Bravo! Compact accessible fun. It's Houdini time! It totally is.

    Sweet! Thank you.

  • nikkes 3 years, 5 months ago  | 

    absolute legend! Really nice format!!!

  • theodoredaley 3 years, 5 months ago  | 

    Simply wow, the first time I have seen a tutorial that makes Houdini "feel" easy to interact with! Thank you for also explaining to add 4 substeps and various use case scenarios. Also seeing the same set up with various stiffness, bend, and constraint parameters really hammers home what we need to focus on to get differing results.

    I'm sure these must take quite a long time to create and edit but truly hope to see more and more and even more series created by you (Advection / RBD / Pyro vs Smoke)!

  • zasid 3 years, 5 months ago  | 

    Very nice to see thing coming from you. I really like your shot tutorials on Linkedin a big fan!

  • JorgeReynoso 3 years, 5 months ago  | 

    This is fantastic! I've learned so much from Paul on his instagram so I know it's going to be great.

  • Loudsubs 3 years, 5 months ago  | 

    Thank you for sharing so much great Houdini knowledge across the web Paul!

  • lightfarm 3 years, 5 months ago  | 

    Amazing !!! I've watched them all.

  • Md Aamir 3 years, 5 months ago  | 

    Amazing! Just wanted know. how did that time offset things with vellum balloons ?

  • PaulEsteves 3 years, 5 months ago  | 

    I'm just offsetting the keyframes of the restlength, so the balloons have time to fall and settle before I blow them up again.

  • emouillet 3 years, 5 months ago  | 

    Brillant Paul, thank you for sharing your knowledge . ( i am already a big fan of your 30 secs series ).
    Cheers

  • blackurco 3 years, 5 months ago  | 

    Clear, compact and fun to watch! Brilliant work Paul

  • AhmedHindy 3 years, 5 months ago  | 

    for anyone having Houdini crashing on the balloon tutorial because of a strange openCl error, download the most recent version since it has a bug fix.
    The reason for the error is Nvidia implemented openCl 3.0 in its drivers and Houdini needed an update.

    • josekrlos 3 years, 5 months ago  | 

      Thank you for the information! I had this problem several weeks ago but the latest driver didn't work for me, today I try to re-install it again and I found another option called NVIDIA Studio Driver, and the problem was finally solved.

  • HazeBjornstugan 3 years, 5 months ago  | 

    Easily the greatest tutorial series for Houdini I have ever seen during all my years of working with Houdini. Short, concise and well explained. I also love the fact that you showed different examples with different parameter settings, that really helps explain what each different parameter does.

    Again, amazing stuff, thanks!

  • Moeen 3 years, 5 months ago  | 

    Incredible work Paul, awesome to see some tutorials from someone as talented as yourself! Love it :)

  • tsiwt 3 years, 5 months ago  | 

    can't get past second 32 when I press play I get - OpenCL Exception: clEnqueueNDRangeKernel (-52)
    error wtf

    • josekrlos 3 years, 5 months ago  | 

      I have the same problem but is because of some Nvidia drivers issues, I'm using the 451.48 old version to make balloon simulations, but if you need to make renders with redshift or octane, you have to update the drivers again.

      • tsiwt 3 years, 5 months ago  | 

        Thank you! I just skipped the second one don't want to downgrade my driver for balloons lol. kinda sucks thou, hope sidefx fixes that.


        Oh and PAUL
        thanks for such amazing videos! you got a good teaching style!

        • josekrlos 3 years, 5 months ago  | 

          hahaha!! that´s a good point! no problem! and you are right!
          Paul is a Houdini Magician this is an amazing series, thank you Master!

    • josekrlos 3 years, 5 months ago  | 

      I found the final solution, you have to install the NVIDIA Studio Driver and the problem is solved.

  • PaulEsteves 3 years, 5 months ago  | 

    Thank you everyone for such positive comments! I truly appreciate all the comments!

  • GiantSpaceTurtle 3 years, 5 months ago  | 

    This is one of the best houdini tutorial series I've ever seen... great job

  • motionpunk 3 years, 5 months ago  | 

    Excellent!!!

  • jim707jim707jim 3 years, 5 months ago  | 

    short and helpful

  • sdugaro 3 years, 5 months ago  | 

    Fantastic series. Love the personality and pace!

  • vaughn813 3 years, 5 months ago  | 

    Thank You, really Great insight

  • geodhk 3 years, 5 months ago  | 

    Thank You, Great Tutorial, In the sixth episode, why can't I find the mops_shape_falloff node, isn't this the node that comes with Houdini?

  • PaulEsteves 3 years, 5 months ago  | 

    No, MOPs is an independent toolkit. Mops shape falloff is a part of the free mops toolkit, you can find more information here: https://www.motionoperators.com/

  • coafablab 3 years, 5 months ago  | 

    Please keep making more videos! I have been aching for something like this on the subject of vellum. Really really good, Paul!

  • richnosworthy 3 years, 4 months ago  | 

    Nice one dude, this is so good to have as a quick reference for vellum

  • jprooney 3 years, 4 months ago  | 

    Wow, what a great series of lessons. Paul's clarity and the included reference files are incredible. SideFX, please do more of these with this guy [and others like him]!

  • seanhedman 3 years, 3 months ago  | 

    Hey Paul,

    Really great and to the point training! I remember you from Matt Estella's Patreon discord. Some really cool stuff here. I just wanted to point out the in your training vid 5, pin to target and release pins by a release attribute doesnt work unless you convert the attribute to integer, as you're saying, i@stopped = release. Below I have posted the link to the file in google drive.

    I dont have MOPs, but made the release attribute by ramping the bbox.y height to Cd and then attribnoise on that Cd and then in vopnet, convert to integer and complement the attribute.

    Cheers,

    Sean

    Pin to target release attrib fix:

  • seanhedman 3 years, 3 months ago  | 

    Edit: as you're calling a float "mops" attrib, im surprised this worked for you....

  • PaulEsteves 3 years, 3 months ago  | 

    Hey Sean,

    Good to hear from you again! Thanks for the file. You are correct, it would be best to stipulate and convert float values into integers. However, even in your setup, if you keep the Cd value as a float, the stopped release still works. This may not be the cleanest way, however, I think as values are still going from 0.0 to 1.0 vellum is able to figure out what is happening. There is obviously no need for a falloff/float value, but, it does work as expected.

  • quadpolar 3 years, 3 months ago  | 

    Hey Paul this is a great set of tutorials. I'm wondering, how did you achieve the multi colored sphere look in an image from the balloon tutorial? I've seen the look before but not sure how you colorized each of those pieces of cloth separately. I'm using cinema 4d and redshift to render. Thanks for anything information!

    • PaulEsteves 3 years, 3 months ago  | 

      What I like to do (both in Houdini and if i'm sending to a cinema4d artist to render) is add a "connectivity" sop at the end. Then a color sop set to "random by attribute" and set the attribute to "class" (created by the connectivity sop). Now each object will have a random color. You can use this color inside redshift via a point attribute into a material blender or color layer to split materials.

  • StephaneS 3 years, 2 months ago  | 

    Thank you, very interesting !

  • vstevenson 3 years, 2 months ago  | 

    When can we expect to see more tutorials?!

    Frankly, your videos are a real pleasure and leave no bitter tutorial aftertaste, if that makes sense. I appreciate everyone that spends the time to share their knowledge, but some are better at it than others, lets be honest. Please make more videos in this vein; everyone will be better for it.

    Thanks again, and best wishes.

  • PaulEsteves 3 years, 2 months ago  | 

    I really appreciate the positive feedback! Hopefully there will be more videos soon!

    • sda502 2 years, 6 months ago  | 

      Record the video and audio in sync (do not record audio and video separately and then put them together), set the video speed to normal.
      No gifs, that's silly!

  • marijamasa 2 years, 6 months ago  | 

    im really new and i tried following the first tutorial but the mesh slided to the right and like a shadow or something fell down - ignoring the sphere

  • sda502 2 years, 6 months ago  | 

    Talking to yourself, aren't you?

  • sda502 2 years, 6 months ago  | 

    Reedit it to 10X normal speed next time. What a showoff with the idiotic gif!

  • Arrrrjun 2 years, 5 months ago  | 

    how do pull of that basket ball going in the hoop
    please help, I really want to make that

  • SerQ 2 years, 5 months ago  | 

    You are the best teacher ;3
    Thakn you so much

  • schnori 2 years, 4 months ago  | 

    Thank you Paul!
    How did you assign the painted mask to the rest length though? I painted a mask with the attribute restlength and then typed @restlength in the "Rest Length Scale" parameter. But that does not work.
    Cheers

  • schnori 2 years, 4 months ago  | 

    never mind. i found the project files :)

  • Huzaifa Hassanzai 2 years, 3 months ago  | 

    Thank you so much

  • tmtcardoso 1 year, 3 months ago  | 

    wow this is great info..short and to the point!! love this tuts ;)

  • walkinginspace 12 months ago  | 

    Love the info. Does anyone know where to figure out/find out how to animate the pressure constraint with a falloff/MOPS? I have yet to find a tutorial and all my attempts have failed. I've seen the effect used by Paul a bunch, but have yet to see how to apply it.

  • Peter T 7 months, 2 weeks ago  | 

    Super Cool! How can you make the Rest Blend work with sand grains?
