Thank you for project files and tutorial!

[@markcharles7467]

The author's explanation is very simple and easy to understand. I think that to understand curl noise, we must first understand what the curl function is, so that we know why we use vdb nodes. I am a novice, this is my personal opinion

[@Rombododecaedron]

Thanks a lot!

[@eloylopez6986]

woow!! gracias! :)

[@autentikum]

Thanks!

[@kemalardaalkin1068]

What is the secret ingredient for the form in the intro picture, I tried mixing another type of noise together to achieve something like that but it didn`t do as I expected and then tried to increase the particle amount, again didn't work, could you help? :)

[@gianlucamatteo208]

Mega cool, could be used to create really nice spaghetti

[@Entagma]

Sounds delicious

[@rob6758]

How do we delay the start time of the simulation?

[@tom.konxompax]

Is it possible to emit particles from a selected group of points from the scatter node? (using groupbylasso) But still follow the shape of the geometry after the initual birth. thanks!

[@Entagma]

Hi Tom, yes it is - just select only the point group you'd like to advect in your VDB Advect Points node. Cheers, Mo

@@Entagma wicked! danke

[@thechromitect9703]

what's the benefit of doing this vdb method, versus just doing a geo then a popnet then a trail? Is it just smoother?

[@Tyler-zb6ec]

Some of my trails are shooting out of frame away from my geometry, any idea on how to fix this? I adjusted the amplitude and surface affect radius

[@stephenhalker2266]

I think it you mess with the curl noise settings it might help fix that. I found that when I cranked up the Surface Effect Radius to 2 or 4 or even 10-20 it had a huge effect on the "stickiness" of the points to the geometry.

[@JZ5U]

Go into your solver node. On the vdbadvectpoints that you copied in, enter without the brackets this --> (@name="vel"), into the Velocity VDB text field.

[@angelinemeitzler3702]

how do you export this?

[@zhungbob9906]

coooooooooooooooool

[@srdjankovic]

Hey guys, does anyone know the process of exporting the trail in alembic to 3dsmax so that I can get splines?

[@shaykh6405]

Can we animate this? like create an animation of the whole process or the noise getting stickier to the original mesh or vice versa?

[@Entagma]

Yes, that's defnitely possible. Cheers, Mo

[@shaykh6405]

@@Entagma how can we do so? i haven't started Houdini yet, have downloaded and opened one time and went through the UI for once. Ur tutorials would be helpful. Can u recommend somewhere where I can get to the fundamentals of why things are done and how they process

[@axe_fx]

I am impressed by your choice of software, the tutorial was uploaded almost in Jan 2020 and yet you use a decade old version. I dont even know if the same method still works or if there is a more efficient way for it.

[@Entagma]

I am impressed by your conclusion. :) This tut's been on Vimeo for quite a while. Just reupped to KZbin. Cheers, Mo

[@axe_fx]

@@Entagma haha wow didnt know you guys had a Vimeo, cheers for the good material you put here

[@Entagma]

Yeah, been doing this some time now :)

[@darshanbhatt9648]

resample node not working kindly help

[@stewmadeit]

Mine isn't animating at all
