Tutorial: Tearing Vellum Grain - Part 2
Переглядів 13 тис.2 роки тому
Following on from part 1 in this video we will be using VEX to build our own custom stitch constraints to glue the grains together. In the process I will setup another simulation using different setting to get a different look to the simulation than the first one. In part 3 I'll cover meshing the simulation. Part 4 will be for Patreon members only and I walk you through the Organic Rock setup t...

Tutorial: Vellum Grass (Basic Plasticity)
Переглядів 43 тис.3 роки тому
Hi Everyone! In this tutorial I create a grass patch in sops and simulate it with vellum as hair strands. I then go through using plasticity to make the grass stay in place when bent by collision objects. As a bonus I also turn the collision object into a dynamic vellum object at the end.

VFX Ocean Breakdown - Roots Night One
is there any way to increase the density of hair??
wow, tutorial?
Hi, wondering if any one know how to add uvs to the sim
So blast and resample both aren't working on my simulation. Blast doesn't have any groups come up in the dropdown and resample just isn't doing anything at all.
for some reason gravity isn't effecting the grains in my simulation, can someone explain to me as to why?
nice information ill try re making the whole solver in blender 😁😁
Thanks, great tutorial
polywire invalid attribute "pscale"
Hi, nice tuto, thank you for sharing, it seem not working for me, the density Fog VDB is X by the number of surface tension? for example 0.2 voxel size in VDB x 15 surface tension + 3?
Thank you,Sir.
Hello. Just subscribed to your patreon :) Some really nice stuff you have there. I'd be very interested to see a revisit to this concept of suction + surface tension.
great tutorial man! one question can you tell who you mentionne in patreon please in the first second ?
Thanks, I should have put his name on screen as well. His name is Jackton Okore, you have probably seen some of his work by now. Check out his Instagram :)
thank you so much and really great tutorial! @@zybrandcg
he have patreon ?@@zybrandcg
usefull stuff!just thinking how can u achieve more glueish fluidy surface rather just grain points?
Thanks, you can play with grains property setting and the stiffness and dampening of the constraints. But being grain you are always fighting that look if you want it more fluid
cool
This was exactly what I was looking for!
Thank you !
is there any way i can achieve same effect using only sops? cant figure out why you dive in dop and have no idea what i am missing here
honestly this tutorial is smth; if you are experiencing some issues recreating this effect: in vellum attach constraint settings, make sure you have Max Distance set to your grain point radius (check that in Geometry Spreadsheet (ex i ve 0.01721 radius so i set 0.02 as a max distance) upd actually thats your Particle Size in grain constraint sop divided by 2 lol impact of settings in ur glue constraint which is on a SOP level in this vid is HIGHLY dependent on Particle Size setting in Grain Constraint node, so i'd recommend to follow EACH step exactly as it shown in video, so u can figure out some relations between settings and how simulation works, then adjust everything to ur liking u gotta crank up substeps and constraint iterations to achieve nice-looking results if u ve lots of grain particles and the most important thing is that u can recreate same effect in SOPs, can't see any reason to split ur workspace using DOP network (im not a specialist tho, but i cant find any good reason to use DOP here)
renderer?
It was rendered with Redshift
@@zybrandcg Thanks, sir, what do think about karma render?
@@bbrother92 I haven't tried it yet. Might give it a go when my Redshift license runs out. Although I am waiting to see what the Redshift volume updates brings as well. At work I use Arnold and Redshift at home so not sure I have space for another render engine in my brain haha
@@zybrandcg One more think, does Redshift have easier to use materials than Arnold? Which one is easier to set up?
@@bbrother92 I wouldn't say one in easier than the other. Depends what you are used to. If anything maybe Redshift materials are more complicated because you have more controls on the shader. What I like about Redshift in Houdini is it feel better integrated with Houdini than Arnold
Hello, I don't understand why the "Attribute Adjust Vector" node uses Points, but the "Guide Process" node is using primitives. I thought we were controlling @benddir with a point attribute? So, when I change primitives to points, these lines don't bend..
Great series of tutorials, thanks a lot! I was wondering if you cover uv unwrapping in part 4 on your patreon?
17:58
really cool tutorial and easy to follow =) what if i want to unglue from the top box after x time? or break that constrain?
I am not sure why but after I after I merged them and try to see the frame , the sphere is deforming and goes in nuts, before merging it works fine, but I follow your tutorial step by step, does anyone know what went wrong????
I mean merging them into vellumsolver
How would you say use attribute paint or a point group that you want to control the surface tension on?
Hey this tutorial is amazing, just wondering how to create the mesh? Im just dive into houdini please help
For anyone stuck at 4:47 Here is the solution: in the "create_surface" node inside "sphere1" > change the attribute "voxel Size" to: ch("/obj/AutoDopNetwork/fliptank/particlesep") * ch("/obj/AutoDopNetwork/fliptank/gridscale") and down to "Particle Separation" change to: ch("../../AutoDopNetwork/fliptank/particlesep") What was happening is that it was linked to the previous deleted "flipfluidobject", so change that to our currently created fliptank named "fliptank". Hope this helps :D
Thank you very much guy
Thank you very much
Thank you so much
Thank you very much!
Awesome tutorial thank you so much! This really helped explain vellum grains and constraints so much for me. I discovered that if you put the glue constraint into the dop network, so you can allow it to calculate on every frame instead of only on the 1st frame, then you get much better results if you want to do multiple squishes. You are right that doing as much as possible in the dop network provides much better, more nuanced results.
Dude do you have a tutorial of this in your patreon? I became a memmber thinking you could have it and I can't find it.
No, I don’t have it yet.
Hey Carlos! Thanks for becoming a partron. I don't know a tutorial about that setup specifically. I made in years ago for the first post on my blog old blog. The closest thing I have to it is my suction force logo build tutorial.
Sensational !! ✔⬆💫
Thank You very muchI
This is sooooo cool hope you good buddy, been looking for something like this to brush up on my houidini
Amazing, thank you!
Sorry man, but you would have to show how you fixed the connections. As a tutorial at least redo the process for those who are not familiar with Houdini. I had to stop the tutorial because I couldn't go ahead. I got stuck there. Good intention perhaps next time you show the whole process. the troubleshoots are important as well.
Hi Eder, sorry about that. Your point is valid I wasn't thinking about all users when doing that and should have gone through the whole process. Will try and remember that next time.
@@zybrandcg Btw great stuff.
It appears that the ship and the water splash on the bow was created on set, so why would you have to make them again in 3d? I can understand creating a proxy model for collision reasons, but it looks like the model is as detailed as the real one and textured as well.
Hi Lukes, It's been a while but if I remember correctly there were more shots and angles of the ship in the show than what they had budget to shoot that is the reason for the detailed ship, I also think the on set ship was missing some piece which were replaced by the cg model. For the water they wanted more splashing and we needed interaction around the ship but the on set splashes helped a lot to sell the final shots. I was only responsible for the water fx.
from where will get the models
I got it from mixamo.com
Duuude!!! THANK YOU SO MUCH for this
if your grass goes completely nuts when you try to simulate it (did for me in h19), try putting the color nodes after the vellum solver.
Not sure what it would be, a lot of things can make vellum hair go nuts.
@@zybrandcg very true, I'm still figuring that out project by project. Vellum is an interesting one :D Nevertheless, amazing tutorial! Thanks for that
Is there a way to attach the vellum hair to an rbd sim that i had cache?
I haven't tried that yet but depending on what you are creating I would rather create the rigid bodies in vellum as well with the shape match constraint and attach the hair to that.
😍 thanks a lot
I learned a lot and by the way that render is just fabulous, looks photoreal!!
Thanks Anton, glad to hear that
What's common use of that thing? Hard to imagine what I can use that for
I don't think there is a common use case for this it's a bit niche. One of my patrons kept asking how to do that until I gave in and did it. :)
Why did you give up in SOP level and dived into the DOPS?
Just because some of the vellum grain settings are hidden at SOP level but it's personal preference really I am used to that workflow from using Houdini for a long time but I am slowly getting used to using the SOP level workflow more.
Epic, thanks for sharing!
anny way to not render as a tube but as geo ?
Milk material tutorial class plz
This was a great tutorial!! Thank you so much for making this!
Did they steal your work in Rings Of Power?
Maybe but I wasn't the first one to do something like this and I made my setup available as a tutorial. If they got it from there I should have changed more :)
@@zybrandcg It's Chladni plates, right?
@@Al1987ac Yes that's right, is a Chladni plate setup.
Excellent tutorial, thank you!
4:39 How did you solve this??
the same problem with me,... I can't follow tutorial
@@bennyiga70 Don't delete any of the nodes! Simply unplug them, it worked for me.
@@blenderdelusions3310 You are the real MVP here.
That was honestly the biggest bullshit I have ever witnessed in a tutorial. "Let me pause this video while I solve the problem"...
