Thank you so much Rohan, im totally new on Houdini, but im getting it pretty well.. maybe also because i've done it maybe 30 times or so.. Greetings from France
hi man thanks for the tut its really helped me. the for each prim worked great when my geo was not deforming. But then for deforming alembic animated characters I had issues using this method for isolating my roots. I ended up using a group range and swithcing my range filter to 1 of 9 and worked great.
The new vellum weld node will hold together the edge fracture and simulate as one piece of cloth without gaps until it hits the breaking threshold. (via Entagma’s tutorial on Vimeo)
If you drop down a vellumconstraintproperty node in the dop network, it has a break threshold parameter. You can use this parameter to enable or disable any constraints. It is also key-able if you want to animate it.
Hi there Rohan, I love your tutorials, they really help me out. I'm currently generating hair on a character for a short film, and the method you show in this video is much more streamlined than the previous one from 16.5, however I am not sure how to connect the guide groom into this network. Would you know how to do this? Either to initialize the guides or to custom groom them in this vellum workflow? Thanks a lot for the info so far, hope to see more of your tutorials going forward.
Thank you Rohan, your turorials are very helpfull for people taking first steps in Houdini. I have one question: Is it possible to make animation on attribiute breakscale to start tearing from up to down? I mean did so using attribiute transfer but Vellum seems to not updating atrribiutes for every frame. Thanks in advance
Your video's are so helpful, I even went to your website and bought the videos on Hair. I do wish that I could figure out some of the problems easier though, like twitchy hair on playback in animation.
@@rohandalvi I actually figured it out- to create constrints dynamically you need to use the Vellum Contraints DOP. It allows you to specify a creation frame and it also allows you to calculate constraints on each frame
@@QuantumNegative www.dropbox.com/s/crffidmfsu9llc4/Sticky%20Cubes.hiplc?dl=0 the dynamics go a little crazy at a certain point, if you can figure out why let me know. Maybe it needs a Pop Drag or something idk
quick question, when you update to 17 do you uninstall 16.5 or can you run both or does it auto update? I've never updated Houdini before. Did a quick search but can't find anything about actually updating the program from one version to the next.
Houdini 17 installed. Now I can add that testpigshead or whatever it is with TAB in Network Editor. I couldn't work out how you were doing that then realized it was Houdini 17. Can't access those objects at that level in 16.5. Thanks mate.
I could get it but I noticed you can't do it at top level in 16.5. You have to add geo1 object first then you can TAB > testgeometry > testpighead. That's when I realized that 17 is slightly different to 16.5. I would have to check again but pretty sure that was case which is when I checked for updated version & downloaded 17 & now I can add testgeometry straight away (at first level of Network Editor if that makes sense).
It’s now called attribute paint. Just type in the attribute name in the paint node and then you can paint into that attribute. For example, if you want to paint color, type Cd.
imgur.com/5Ww06Dt this is what i have. i tried using all 4 alembic to export it with still only give me fabric an not the grain. i assume i am doing something wrong. An thanks for taking the time to reply :)
@@tomjerry84 it's not meant for fluids. It's primarily for cloth, hair and soft bodies. I'm sure there must be a way for fluids to interact with it but it didn't seem to be anything straightforward. Wait for some of the VFX masters to figure things out. :)
my friend you have beautiful lessons but bad english accent please work hard on fixing it and thank you so much for your lessons ı am following you here and in Vemio best regards
Hi Rohan, you can get a smoother looking hair result if you keep cranking up the influence radius past the point where you get 100% coverage, instead you want 2x or 3x as much so the influences blend together!
Dalvi: Anyway, that's basically it.
Me: *Mind blown*
I'm so glad I found your channel. It's been a huge help! thank you
Muchas gracias , Rohan! Great start video.
Thank you so much Rohan, im totally new on Houdini, but im getting it pretty well.. maybe also because i've done it maybe 30 times or so.. Greetings from France
Great stuff man, thanks for the detailed walkthrough!
Thanks Rohan! Very helpful as always
Wow very quick, thank you as always!
Nice. Thanks Rohan. You don't have to shift drag over a key in the timeline anymore. Just middle click drag on the key works fine.

Great intro thanks!
like your learning videos . keep it up
super handy this Rohan - thankyou :)

could you do something about plasticity in vellum?? as the example in the launch presentation in minute 18:00 exactly?? thanks in advanced

Thanks
thank u :)
what do you recommend for a total beginner? thanks
Hello Rohan! Cloud you answer my question: where can I find spring sop in houdini 17? Thank you in advance!
I think they removed the spring SOP. There is a spring node in CHOPS, I think. You could try using that.
@@rohandalvi thank you very much
Thanks a lot. It's time to drop Yeti and Maya I guess now.
I am learning Rohan's "intro to Houdini" as we speak. I won't drop Maya.
I will not drop Maya neither. I meant Yeti/Maya for fur .
This seems very easy to learn and use and it should be a lot better.
so dynamics is crap DDDD
the other quick way to group the root points is using wrangle with : setpointgroup(0, "roots", @ptnum, vertexprimindex(0, @vtxnum) == 0);
There's a preset in the group expression node that selects the first vertex. I found that later.
@@rohandalvi nice, I didn't konow, haven't been using group expression node often :)
@@3donwong I use all the group nodes. I don't think I've ever created a group using the wrangle node. :)
How can I stick one object to another? In the SideFX example reel they stuck the rubber toy to a spider web, how do you make that work?
I'm not sure. I haven't tried all the various constraints as yet. I'm also not aware how to activate constraints dynamically or over time.

You can keep both versions. You can keep as many versions or build of Houdini on your machine as you want.
Houdini 17 installed. Now I can add that testpigshead or whatever it is with TAB in Network Editor. I couldn't work out how you were doing that then realized it was Houdini 17. Can't access those objects at that level in 16.5. Thanks mate.
Steven Silcock the test geometry has been available since Houdini 15. You should have been able to access it in Houdini 16.5
I could get it but I noticed you can't do it at top level in 16.5. You have to add geo1 object first then you can TAB > testgeometry > testpighead. That's when I realized that 17 is slightly different to 16.5. I would have to check again but pretty sure that was case which is when I checked for updated version & downloaded 17 & now I can add testgeometry straight away (at first level of Network Editor if that makes sense).
I've done the pigs head, worked great. Just about to start the next one thanks to such clear & easy to understand lessons. Great stuff.
你特效软件实属强无敌软件
Is this still valid in 18.5 version or is there any different way to make this?
hi, do you know how to replace the paint node you use in 19:32? because houdini 18 deprecated it ... thanks
It’s now called attribute paint. Just type in the attribute name in the paint node and then you can paint into that attribute. For example, if you want to paint color, type Cd.
@@rohandalvi thank you!!
is it possible to export it o.o? i tried but it will only export the fabric an not the salt ? o.o?
You can export both those things using alembic. Alembic supports particles.
imgur.com/5Ww06Dt this is what i have. i tried using all 4 alembic to export it with still only give me fabric an not the grain. i assume i am doing something wrong. An thanks for taking the time to reply :)
@@dragerx001 I'll try to record a video for it.
Oh thanks that would be great :D.
What about animated objects? How to simulate hair on an animated character?
I'll look into it and let you know
@@rohandalvi Thank you! I'm really looking forward )
Can it interact with fluid?
No, they don't interact directly. I did a basic setup and the fluid went through the vellum cloth.
Rohan Dalvi Wow, then this means it's just a half-completed engine?
@@tomjerry84 it's not meant for fluids. It's primarily for cloth, hair and soft bodies. I'm sure there must be a way for fluids to interact with it but it didn't seem to be anything straightforward. Wait for some of the VFX masters to figure things out. :)
Sir can you teach us nuclear explosion in pyro houdini please sir make some tutorial please sir please
I'm not very good with pyro fx. I'll see if I can find a tutorial for it and send you a link
@@rohandalvi Thank you sir

who is smarter than you?
Lots of people. David kahl, entagma, Jonny farmfield :)
and when those guys say something it goes from the top of my head
You are an amazing instructor rohan.2 yrs into houdini and I thank you for helping in the journey.
