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.
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
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)
Very nice tutorial so far, but I'm hitting a block. Currently trying to get the collision to activate in the Vellum setup, I've done everything as you have and it still keeps going through the grains
Hi DParagon! Glad you like the tutorial so far... the collision problem sounds frustrating though. It should work as I did it in the tutorial but if that isn't working for you for what ever reason you can try and create a collision object from the vellum shelf instead. It works best with the collision geometry in a separate object.
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.

This was exactly what I was looking for!
great tut. The breaking threshhold scale and long vertical noise is exactly what i needed!

Thank you for the tutorial, very well explained and very useful, more tutorials please
nice information ill try re making the whole solver in blender 😁😁
really cool tutorial and easy to follow =) what if i want to unglue from the top box after x time? or break that constrain?
Duuude!!! THANK YOU SO MUCH for this
Excellent tutorial, thank you!
usefull stuff!just thinking how can u achieve more glueish fluidy surface rather just grain points?

Hi, wondering if any one know how to add uvs to the sim
Lekker to see other south africans working in the vfx space!
Dankie MP :)
for some reason gravity isn't effecting the grains in my simulation, can someone explain to me as to why?
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)
@@rennightmare Did you listen to a word the author said?
@@khomatech0 sure
you?

@@zybrandcg Ok, thank you! I'll give that a try.
@@youngdevil131 same here !
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.
where is the organic rock setup :(
That one is for patrons only but all the simulation components you need in covered in the free tutorials.
Why tf are your grains going up and not down (anyway nice tut mate)

I mean if I set the gravity to 9.80665 instead of -9.80665 evrything will be okay but that's not what you did
I'm also confused by this rn. Did you find it out eventually?
@@plsreply Mine is literally defying gravity and I have no idea why!
