Hi All, Let me start by saying I am still learning, I am in a situation where I'm doing a large scale destruction with RBD Bulletsolver and 10 frames in Houdini crashed. Do i have to restart the sim from the beginning? or is there any way to setup some check points like Dopnetwork....

Hi guys! I have a super simple question (I hope at least). I am using two different geometries and merging them together as cloth to dopnet. Inside the dopnet, I want to define different behavior (sturuts stiffness) for each geometry. It, unfortunately, doesn't respond, though. I just cr...

Hi all I'm stuck with this. What is the best way to mix two fluids that have different parameters (i.e viscosity)? Both will have different shadings. Any ideas. Attached reference scene. Thank you very much to all Mix_flips_RnD.hipnc

Hi everyone. I have a newb kind of question. I have a file cache of a flip sim I have done. I want to set the color on the first frame have that color "stick" to the particles and let them mix. I am using an attribute adjust color node to assign a noise to the color of the particles however the colo...

I cant get the nearpoint function to work inside of a dop network. it works perfectly in sops.. If someone could take a look at the file I would really appreciate it. This is the effect I'm trying to achieve - selfsorting.hiplc

I'm working with RBDs and I want to apply a popdrag only to my fractures from the rbdmaterialfracture node that are in the concrete_chips group. These groups don't seem to come in by themselves, and after a bit of trying things, I found the POP group node... The way I'm doing it now is: I...

Hello, I'm new to Houdini and this is probably very simple. I have a simple scene file that was made with the Entagma vellum tutorial https://vimeo.com/294374382 How would I use point deform to apply the high-res pig head on to the low-res pig heads with the dopnet continuously emitting th...

hey all i'm sure this is a fairly simple one but i'm having a hard time with it :/ been at this for 6 hours today so i have a sim of a big wall exploding outward - it looks great but sadly i have a huge chunk of pieces that fly towards cam an i'll be damned if i can find a way around it -...

Hello, I have noob question. I'm animating the sphere collision by keyframe. But, I get some errors and the collision goes through the active object. Particularly, "Target geometry does not contain a name point attribute" error message is strange... Is there anything way for fix...

Hi all, new to the forums and new to Houdini although I have a long history in Maya, I have never really gotten much into simulation until now. I've been messing around with the shelf beach tank to make a simulation of waves for a project I'm working on, but I'm a bit stuck on the caching phase....

I want create the volume with the particle. BUT, I don't know how to control the volume in dop network. I would had search during a lot of time in , but i had been not solved... wall.hipnc

Hii. I Have made a Pyro smoke Simulation but my Pc is damm slow. So i decided to Cache out .sim file from dopnet. After 20hrs it cache only 67 frame and Houdini got crashed. so when i reopened the Houdini and loaded my .sim file it only read from 52 frame :-( but i have cache 67 frame. an...

Hello, I'm sure my title for this post could be clearer, so for visualization purposes, say I have a field of discs that are RBD Packed Objects on the XZ plane, and above them there's a sphere with gravity: Normally the sphere would fall onto the discs and the discs would act more or...

Hello, I'm trying to access a microsolver in the Dopnet. I would like to get e.g the disturbance parameter of the disturbance node, which has the parameter name: "dist_scale". With a Gasfieldwrangle node I can access e.g @vel, @density.. basically attributes.. which is working fine if I am...

Hi Guys I have a fairly high res flip sim (by student standards, about 3 gig per frame) and I needed to cache it out as a .sim to utilise checkpoints I need to read this simulation in using playback simulation on the dopnet and a dop IO node with the flip presets in order to pull in th... -
Hello! I have this vellum grain simulation that is pretty high res, so it takes a bit of time to calculate. What I did was simulate the first 50 frames to get a good rest position for the grains. I set that 50th frame as the initial state for the simulation. Here is where I am unsure. I made so...

Hello All, I'm looking to create a pile of RBD objects that are emitted and scale over time. I was able to get relatively close by watching a few tutorials and finding a thread on here where a similar question was asked. However I don't have a lot of experience with dynamics and I'm hav...

hey all! I have a rbd sim made of several rbd packed objects, and now I'd like to cache it out but export each rbd packed object as a single alembic file, ideally I'd like to cache the entire sim for review and secondary simulations (smoke and debris) and then separate the cached version by tho...

Hi, It seems that generally when animating objects in scene/object level, you are only able to animate variables globally. I have a scene with a spinning propeller, and this spinning propeller needs to rotate around its own axis, while being placed in a certain spot in the scene. How is th...

Hi, I am currently creating a simulation with flip fluids that are affected by a vortex force. I need the velocity/lift attributes to be animated independently throughout the simulation, though no matter how I set the settings for either the sop geometry, or vortex force operator, the valu...

Hi, I've some question about the dopNet, and the memory performance: I currently query the memory used in the simulation in this way def memConsumed(): try: sim = hou.node("../.").simulation() return "%s" %(str(hou.DopSimulation.memoryUsage(sim)*0.000001)) excep...

Hi, I have a simple particle setup here which has attribute wrangle providing velocity in the second input of my dopnet. How can I use that velocity in the second input to affect my particles or (RBD)? thanks in advance vel.hip

Hi, I have a very simple DOP network with 2 static object colliders. (Houdini 16.5) In my scene, I'm instancing sphere on the particles from the DOP simulation. The spheres are instanced perfectly to the particles of the dynamic sim, but they are also wrongly getting instanced on each...
