Hello! I've been using Houdini as a TD for about 2 years now and I just recently got my hands on a C4D and X-Particles license. Playing around with X-Particles it has become apparent that Houdini can make something fairly simple (like particle simulations with constraints) very difficult. For these past 2 years I've been trying to get, specifically, thick liquid like particle constraints (not just viscous but stringy) working in Houdini and I've never been able to get results I can be completely happy with. I've been able to achieve "sticky" effects using vellum grains and vdb meshing before as seen here, however, I was always after a different effect using a particle simulation that was NOT attached to a mesh but still behaved in a similar "sticky" fashion when coming in contact with colliders. After trying this over and over again in Houdini and having unsatisfactory results, I've now experimented with X-Particles and I was a slightly frustrated by all of the time I had spent in Houdini and how simple and quick it was to achieve exactly the effect I wanted in X-Particles. In the video below you can see what effect I was after in XP. I was curious if anyone at all has re-created this stringy liquid effect in Houdini with POPs? It seems clear to me that FLIP fluids are not really the answer for small scale simulations where you want a "stringy" surface tension look. I've gotten close with FLIP and vdb meshing in Houdini, but it never looks as natural and real as X-Particles. I've heard that maybe the POP Fluid node may be the answer (here), but I'm curious if anyone has attempted these stringy constraints in a Houdini project! Any Houdini workflow tips for such an effect would be appreciated because the cost of X-Particles and C4D is not something I plan on paying for the rest of my days!

Hello! I'm trying to make an effect where a logo emerges from a tank with a viscous fluid. I want to have the liquid quickly flow off the logo once it emerged. It has a round surface, similar to the torus I exchanged it for in the hip-file I attached. I'm aware of viscous fluid's stickiness and turned on "slip on collision" and also tried the "gas stick on collision" cheat I found in some older thread, as well as using normals to drive the velocity. however some particles always stay on top of the surface and won't flow off. What would be a smart way to cheat and clear the surface of the fluid? Thanks in advance! J. 190620_Instagram_FlipTankExample.hiplc

Hi guys, Just wondering if anyone out there could give me a hand or point me in the right direction for something I am trying to achieve with an RBD simulation. Basically I have created a fracture simulation which gets launched at a character and I'd like to be able to stick the pieces into/on the character. I have been trying to investigate dynamically creating glue constraints but have hit a bit of a wall. I have seen that I can record impact data but I am not too sure how to process this in a way that would then lock the RBD object to the collision object. Any help would be super appreciated.

Hi, please see the attached Cinema 4D video of what I am trying to replicate in Houdini. I want to interactively position an object on a surface using handles. I made some progress with the Creep SOP, but it has several limitations: it deforms the source object, which I don't want it doesn't have viewport handles, so I have to edit the node parameters, which is undesirable (I have a lot of objects to manually position, so I want to make it as easy as possible) it doesn't work with polygonal objects I don't mind using VEX or an Attribute VOP to achieve this. Thanks. Slide_on_Surface.mp4

Hello everybody! I'm trying to get this sticky glue effect like in the picture below. Does anybody know who to set this up in Houdini? I do have some experience with Houdini, but I simply can't figure out how to build this one up ;-) Any help is very much appreciated!

Hello guys. i was trying to make sticky glue, that 100% sticks to two objects (never peals of). I have two boards, each with piece of slime, as they touch, slime should join and as they move apart, the slime should stretch and break apart (but never peal off from board). I did spend some time, investigating, but im having hard time to force the slime to stick without pealing. anyone can point me in better direction?

Hello. After stepping on the gum, I want to make the effect that the gum breaks by lifting the leg. I added Viscosity with FLIP and tried it, but it does not work. How can I make something like this picture? please tell me. Finally. I am not good at English, this sentence used a translation site. I am sorry if I have the wrong word. sticky_test001.hip

Hey magicians, I'm trying to takle an effect wich a Splash sort of come out of a screen, Any suggestions on what would be the Best way to approach something like this? Flip fluids with density driving by color? Particles to vdb with vortex? Thanks in advance

Hi, I'm new to Houdini and I'm trying to create a dandelion blowing in the wind type of effect. So far I have the constrained the dandelion seed geometry on a sphere and have created a pop network so the dandelion seeds fly off. This is fine however I'm trying to find a way to make the particles stick to the surface and only fly off the surface when the seeds reach a certain angle ( say 20 degrees ) from the normal. I've been looking at this tutorial of how to create this effect in Maya but I'm finding it difficult to translate this into Houdini. I think you're supposed to use VOP's to create the same effect but I'm just a bit puzzled of how to do so cause I haven't used VOPs before :/. Maya Tutorial I've attached my file below. Thanks in advance! DandelionGeo.hipnc
