Man I used to hate math in school (like most people) but since I started learning Houdini and being able to see what beautiful motion is generated by such a simple calculation it is truly mind blowing and I love every aspect of it now
OMG, I needed this last week haha! I was like, I need stuff to swirl around points, but math math math and work work work, and I was down to like 15 brain cells... I had the cross product part in my head, but the implementation, not so much. This is awesome, thanks!!!
Quick tip for anyone who wants the particles to move with that velocity field on the sphere. Use a SOP Solver in the popnet under Advect by volumes, go inside. Use Ray node attach first input to DOP Geo and second input to an Object Merge to which is locating the sphere and select Minimum Distance, gives sweet results as well!
For anyone not being able to see the fog volume but just the bounding box: You can visualize the "vel" volume once it has been created by middle mousing on the node info and left clicking on "vel" - just like visualizing attributes. Hope this helps.
you explained how cross product works better than all the math theory videos I watched on it before this. It finally became intuitive for me, thank you!
Beautiful. As always, I am perpetually thankful for all the work this youtube channel does. It's given me so much confidence within Houdini.. and even more importantly.. has given me a passion for life again. Thank you.
Thanks for the refresher on creating velocity fields for particle advection! I seem to forget parts of houdini as focus different parts for extended periods!
This tutorial was awesome! For me, this bridged what I had learned in Steven Knipping's lesson on swirling particles and Peter Claes' lesson on dot product. I've been wondering what is the best method for advecting particles, but still maintain a certain level of control and detail. Looking forward to trying this out. Thank you.
Thanks for explaining the dot product again. I had my brain working on this several times but somehow had trouble applying this towards Houdini. You're tutorials are really helping me probably others too. Thanks again!
More of this please. Once again, Entagma, I'm wholly indebted to you guys for my Houdini learning journey. Wonderful, wonderful, wonderful tutorials. Once things pick up again after Covid I'll definitely become a Patreon, no question. Greetz aus Mainz :)
love this tutorial. what oftentimes falls a little short imo is how to render all that stuff properly, in this case the particles and splines, because in the viewport it looks great but when it comes to rendering, things can fall apart really quick.
You can visualize the "vel" volume once it has been created by middle mousing on the node info and left clicking on "vel" - just like visualizing attributes. Hope this helps!
Hopefully not dumb question(!): at 4:45 in the vid ... why is the purple arrow (you say the normal of the purple face) defined as being in it's direction, rather than exactly opposite????
Anyone having trouble with an empty bounding box after setting up the VOP correctly should double check if you changed your normals from vertices to points!

Thanks for this is a really cool tutorial. How would one go about exporting the result we have into Maya to be able to render? possibly with the color information we have setup
Only real question I have is how do I get the render to look like smoke because mine looks like a slime ball which is cool but I do not know if I missed something or messed something up :(
Hi! Great Tutorial, i hve a stupid question tho, how to change the particles size? i can't find the pop up window anywhere, neither i can't fsolutions online, can you please tell the shortcut u used? thx again for the tutorial!
How do I color the particles using the v attribute? I can create a ramp from attribute with the color node and it works fine in the viewport, but when I try to import the v attrib. to octane render it doesn't work properly.
I rendered it out, but it doesn't look like what you rendered, its realy dry and missing those smooth foggy look, how did you do that? from comp? thanks!
I am getting this error in the Volume VOP and I am not getting any results from the VOP... ..... Warning Cannot find primitive attribute 'name', binding volume as 'density'.
Hi there, and one more dope Tut featuring dope fx here ! im following the steps, I just got a viewport volume vop display problem, it seems i cant get the voxels shape displaying at all, just got the bbox, ive tried out everything possible in my settings but nothing helps, except the volume slice node technique which is not a proper solution, and as i can see on Simon's work, he gets the volume perfectly displaid, as it s necessary to preview tweakings the right way... any help ? thx a lot by advance, best, L.

so what's the vex equivalent of that VolumeVOP node? I find VEX debugging to be like taking a trip 20 years back in time. In a VolumeWrangle at the same place as the VolumeVOP // declare bindings vector @P; vector @vel; vector cloudP; vector cloudN; int handle; handle = pcopen(1, "P", @P, 1.0, 1); while (pcunshaded(handle, "P")) { pcimport(handle, "P", cloudP); pcimport(handle, "N", cloudN); vector voxel_to_geo = normalize(cloudN - @P); vector newv = cross(voxel_to_geo, cloudN); @vel = newv; } pcclose(handle); I think this is close-ish....
Can you make a tutorial for vops 1-10 by making a perfect effect like the explosion of fire, water, waves collapse without vex, I see that there are many who need that teaching, especially for those who are new to Houdini
Can anyone help me out with the render settings or how to render this? Mine looks like a corona virus thing :(. I?d love to render out a beautiful swirly particle instead of a virus ;)
Houdini is so.. strange. Like I understand every single thing and why are you doing it, but to do it myself, from the beginning? Remembering all those names, vops, sops, use of floats, vectors etc, the specific options that if you not chose all of it won't work.. I fail to see the logic behind some of the concepts and even if I did some thing, I am unable to do it again after a month..

Hey, if I am not mistaken you were one of headliners on Mouvo Festival in Prague several years ago! Thanks a lot for great tutorial :-]
thanks simon! love the guest tutorials
Thanx Entagma and SSimon for this. Really clear and logic to understand
Thank You very much, Simon! Thank You very much, Entagma!
Great tutorial , I am amazed how simple he has made it look.
SAVE BEFORE 19:30 if your computer is not very stable going from the random colors to the popnet crashed my houdini lol!
star guest simon!!!!!
Such a beautiful result, and what a clever flexible setup! Thank's so much for the idea!
This setup is very clever. Fantastic video!
Seems to be breaking in the Houdini 19.0 at 3:25 onwards ; If anyone figure out a way, please help! Thankss
Amazing! Thanks a lot. The things you can do with this in depth control. Its crazy!
This is so helpful! I love these tutorials. Whoever downvoted this, I hope both sides of you pillow are warm at night
if anyone’s rendering in mantra if the points appear large just do an attribute wrangle on the pop net and set to @pscale = 0.002
This is brilliant ! Thank you for this tutorial ! I love it !
I love this kind of tutorials!, that teach how to make a full project
could you please make more tutorials like that?
Amazing. Thank you
seems to break in H 19 as I am getting an empty bounding box when selecting vector float in VOP. Any guidance? Others below are asking too.

Hey do u know why the particle in the render View and in the scene View looks different?
Anyone having trouble with an empty bounding box after setting up the VOP correctly should double check if you changed your normals from vertices to points!
Thanks sir
@@gouthamvanga5129 Yes thanks a million, been trying to figure that out for a while this morning
Came down here looking for this, tyty. I was using custom geometry, so my brain said "it already has normals! dont need that node"
Ends up I do.

Out of curiosity, what is the particle count and particle separation in the title animation for this tutorial?
If I remember correctly it was something around 5-10 Million Particles. Redshift can render those pretty fast, so it wasn't that heavy.
Awesome. Wonder if that was rendered with Krakao?
It wasn't :)

THIS IS AWESOME but the theory section went way over my head..... also RIP my CPU
This is broken in H19 unfortunately. I think the new mountain node is causing it. Tried many things to fix it with no luck.
raise Search radius of pcopen node in Volumevop, it should work.
Now I need to do this but on Blender...!
Good luck with that...
wwwow
First!
Good,
if only showed how rendered, would be better. Sorry for my english ))
