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

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

Muchas gracias , Rohan! Great start video.

Wow very quick, thank you as always!

Thanks Rohan! Very helpful as always

Great stuff man, thanks for the detailed walkthrough!

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.

thx! these are so good for starter like me~~~

Thank you so much man! Keep it up :)

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

like your learning videos . keep it up

super handy this Rohan - thankyou :)

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)

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!

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.

Thanks man.... You're a life saver....

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

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.

Manny Wiebe thanks. I covered it in my second vellum video. :)

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.

Brilliant!

Is this still valid in 18.5 version or is there any different way to make this?

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 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

hi, do you know how to replace the paint node you use in 19:32? because houdini 18 deprecated it ... thanks

@rohandalvi

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.

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.

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.

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).

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!
