Hi guys, I hope you can help me with setting up this vellum inflation scene... Basically, I have animated a sphere expanding and used the rest blend node inside the vellum solver to inflate the sphere. What I would like to achieve is an interaction where the vellum inflation sim interacts...

Donuts & Cupcakes! What? This is the theme of my new 3D animation [V2] of dominoes falling down! The goal? Have fun and training my skills in 3D simulations under Houdini v18! Technical details : - Houdini 18 -> Modeling, textures of Cupcakes and Donuts, rigid body dynamics simulations, p...

As you can see in the image below. If the rigid body is on the left side of the merge node the rigid object doesn't obey the force of the flipfluid and if the rigid body is on the right side the behavior is odd. what's the correct workflow?

Hi guys In a simple rigid-body simulation, I set the "Active" attribute of my animated object from 0 to 1. How can I limit the inherited velocity (v@w, torque) of rigid body objects? I mean I don't want them to spin and rotate after becoming rigid body! Thanks for helping....

I'm trying to get these two objects to move towards each other after they hit the ground. Blend solvers are being used to allow the objects to transition between their keyframed positions and dynamic states and I need to add an attractive force which is what the spring constraint is supposed to be f...

Hello I would like to create a Fluid-RBD interaction. But as you can see in the image below, the fluid pushes the rigid body so strongly. I need the rigid body to be a little bit heavy and to float on the fluid, based on its mass attribute. (Decreasing the "Feedback Scale", didn't hel...

I`m currently testing with vertex animation texture and i want to walk around on fractured pieces using my character but it seems not working. is there any way to make this possible? Vat seems like moving meshes but seems like collision position is not applied.

Hi everyone ! I'm having issues with the voronoi fracture on concave geometry. I'm trying to fracture a pillar which was created in C4D. To do so, I create a VDB and scatter points in it, then I use the Voronoi Fracture SOP on the base geometry. It works quite well overall, however on some...

Hey guys. am recently decide to use houdini as a 3D package and i have an issue in a rigid body simulation. The problem is: i have a chain ring that should drop on the floor and after dropping all ring chains should interact with each other. at this moment when i drop chain ring, all cha...

Hello, I have been making several attempts to accomplish something like Matt Taylor's Seeds concept https://youtu.be/vUvEy37LhqE I have tried a couple of approaches including using a multi-solver but no luck. would really appreciate any input that helps!...

Hello, Houdini folks! I have a question about very essential thing durring the rbd simulation. (Im attaching the file here). What I have, I want to change the scale of the pighead, durring the simulation, but without this "strange jumping" behaviour. Any suggestions, how to solve? Thank yo...

hey guys i am having a little bit of an issue with this test. i picked up this setup from another thread on this forum however in this particular scenario it doesn't seem to work as i am probably missing something. basically the pieces getting activated and falling, do not collide wit...

Hello everyone! This is the first demo of a new tool I've been working on in Houdini. The idea is to simplify the process of adding steel reinforcement in concrete fractures, specifically FRC (fiber reinforced concrete) My aim is to produce a single node that takes your simmed geometry and...

Hi, I was just trying to replace my pieces with hi quality instancing but it gives different geometry in Rigid body Simulation? Could you please guide me where did I miss MANY THANKS PREM wall rbd sim v7.hipnc

Can anybody help me with a method of using the rbd material fracture node and run it through the destruction cleanup tool in Houdini 17? I just need to understand how to provide the correct data to the cleanup tool to get it to work properly. I am just looking for the most basic setup because I c...

Hey! I have a bunch of pieces from a fractured geo, and I plug them into a rbd bullet sim. I have very big and very small pieces, which is fine, but the problem is that if I let the rbd packed object to calculate the mass obviously I get very different mass result (and that is absolutely correc...

As I'm just starting to understand quaternions and orientation in Houdini, I'm not sure how complicated this is to achieve. I could be completely over thinking it. Ultimately I would like to create a force in dops to rotate the packed object to its current direction of motion, or it's velocity....

two way collision between grains and rigid body
bobbybob posted a topic in General Houdini Questions
Is it possible to create two way collision between rigid body and grains? I am trying to make a simple example where a sphere is dropped down in a container of grains. -
Hello, could someone explain to me what this parameter does exactly? What is being sampled for tolerance?

Hi, I'm trying to get a rigid body destruction simulation working in Unreal 4 as a vertex animation using the Game Development Tools. I've got it looking pretty good in game now, except some of the pieces tend to randomly flip briefly as they rotate. It usually looks wrong for about a sing... -

This roadblock stemmed from this thread that was started here. I thought, wow, this is awesome, you can do so much - such as fracturing. However, when I tried to just do a very quick "let's see if this works" setup in my DOP network by adding a Voronoi Fracture node; it ignored it. <~This was using...

Hi everyone! I'm relatively new to Houdini, and I came across a tutorial which explained the bullet solver for H13. I am trying to recreate the effect that he got at 53:15, where primitives were deleted from the constraint network when a force over a certain threshold was applied. tutorial...

Hey everyone,My overall goal is to simulate liquid poured into a glass with ice cubes inside, with the ice cubes floating.Everything works normally until I enable feedback forces: Normal: https://gfycat.com/LameCarelessIzuthrush With feedback: https://gfycat.com/FlashySolidFreshwatereel...
