here is the simulation

https://www.youtube.com/watch?v=I1cNctgGmhE

Just like getting a real biscotti through a real dounut, friction is your enemy. Set it to 0. Animate that parameter if you need it in other parts of the simulation, but you probably wont.
Heres the real deal though. You will spend the rest of your life fine tuning the parameters of the dynamics and never get it right. You want save yourself work as opposed to animating the thing with bones and blendshapes.
I would strongly siggest a hybrib approach. Make a static doughnut you animaye by hand. Broad strokes animations. That mesh drives a dynamic mesh which is trying to copy the static mesh which is also sensitive to momentum and collisions.
Ive been researching biscotti doughnut rigs for awhile and what i keep coming back to is that the solution is blend shapes and bones.

Here's one i made to test. Also a cloth sim with vomume conservation.

tried adding bones actually helped alot thanks anon!ill keep posting as i go along currently trying to add shapekeys

This tutorial is of course a classic, referenced to do the thing on the left: https://www.youtube.com/watch?v=bLps8bgIeJ4

the general idea is the shrinkwrap on the eight guide bones will keep the donut hole wrapped around the biscotti, but only if the biscotti is between them and the hole is smaller, apart from that it just follows whatever motion you animate

this is incredibly usefull thank you!

adding bones helped a ton do any of you know how to get shapekeys to activate the closer bone the further away bone A pushes bone B?(limit distance bone constraint)

Thought of this thread after making this
>>>/h/8813050

>>1024439
One way is to make a bone stretching to bone B then use a driver based on (stretching bone's length -1)/expected max length, on the shape key's weight

>>1024471
whoops, meant scale factor -1

Updates?

>>1024982
my bad man i forgot
i set it up so that each bone streches the donut in a different direction when the biscotti gets to close and added a cloth modifier to give the donut "donut physics" its too jiggly and dosent maintain its shape as well as it should but i have a good feel on what to tweak to get where i want to


heres the progress and the modifiers and simply wrap pro settings i used to get the effect,still trying to figure out how to make "coffee" splash out of the hole or have bubbles come out of it thats where im at

didnt think the quality would be so bad here are the current settings

>>1025061
Needs more dampening. That'll settle it down quicker.

why are you making an animation of a dog vulva being penetrated

>>1026344
How do you know what a dog vulva looks like?

>>1024300
How would you do a hotdog sliding between two large buns roughly D size?

>>1026366
You say that like dogs normally wear pants.

>>1026477
Conserve volume cloth simulations

>>1026477
You can to that with a shrinkwrap constraint

Is there an indepth tutorial on this i need to do a door from halo 3 in blender

>>1030813
You gonna need to elaborate

>>1030834
Guys asking how to rig asshole asked what kind? Fuck me

>>1030834
It's pretty clear what he is asking

>>1030902
I couldn't hell, I haven't played Halo 3

>>1030902
>>1030903
Me looking at the thread topic wondering how you wouldn't know

It is a mysterious in way your ignorance

>>1030906
The topic is about baked goods, not videogames

>>1030908
So how do you do baked good Rigging my dude

>>1030919
The donut rigging tutorial was posted earlier in the thread, is as relevant as ever

trying to give my character harry "nottapussy" gashberg a hairstyle with greasepencil but it dosent look as realistic as id like it to,any advice on giving the GP a very small outline,changing the colors of each hair randomly just enough to make out the shape of the hairs or advice on making the hairstyle itself look more realistic?

also do any of you know if theres a way to make greasepencil react to a deformation cage?or make a hair sim in geo nodes and have each hair go from mesh to greasepencil+greasepencil modifiers?

any advice on armature-weightpainting setup for buns?how do i set them up for twerking and spreading(butter)?how do i make the raspberry reveal itself when the ripped loafs move back and foward without having it be out all the time?

>>1030997
>make greasepencil react to a deformation cage
Just look through the deform modifiers you have for grease pencil and choose one

Any idea how i would animate something like this cherry blossoms.

>>1031035
Just look up tutorials on mouth and lip rigging, exact same principles

So I have this female body model, and I want to tweak her donut to make a bit fatter but I can't seem be able to get the shape right.

>>1031057
If it's spmething you can't explain without picture just do it in the /aco/ thread. You know, the one that has links and tutorials for that kind of stuff.

>>1031069
I completely forgot that /aco/ existed, thanks you I'll go there.
