Hi guys, I'm trying to understand how the "Gas Field to Particle" DOP works. I've set up a test scene, but it isn't working as expected. Any ideas on how to troubleshoot the issue? Thanks for helping. gas field to particle 01.hip

Hello, I'm trying to do a particle morph effect and all I want to do is to have the animated data imported into the pop network. The effect is from a tutorial by Nicolas Donatelli (https://www.youtube.com/watch?v=B4Zz8Erc09E). Morphing works great but only works on a static geometry and I would...

Hi, I'd like to set up a simulation where there's a small container, and half of it will be filled with liquid. The initial state of the liquid should be static, like a cup of water left on the table for a long time. Then I'll introduce a rigid object to collide with the liquid. Sounds simple, right...

Hi, I was wondering how to approach this effect since I tried an approach using particles on a flip solver and on top of that adding a pyro simulation to recreate the mist. But I'm having trouble to achive the "cone" look (attached image) since it keeps spreading and losing power while the part...

Hello dear people of the force. In lops: I have been trying to set up a simulation that takes existing point instances and then modifies them with a dop inside a sopnetwork. I have been looking at the drop node to try and kitbash a solution. I keep on having the problem that it jus...

Hi Houdini friends, Does anyone know how to use mask field in DOP net? I'm doing a simulation of leaves on the ground reacting to a car passing by. I need to control the wind force to affect only where the car is passing, where other leaves remains more still. Is there any way to mask out the a...

I have an AutoDOP Network that I am trying to select for 'heat within object' feature. No matter how much I try to click and select, drag a window around it, it doesn't get selected. What should I do? Sharing a screenrecording of what I face. selection issue.hip

Hi, In Dop Network, my Hitters should HIT the ground, but I properly cannot solve this problem, How to fix this, Please ground.hipnc

Under dop network I want to implement many node functions with wrangle Can this bypass the learning of nodes? I know it will involve a lot of vex code and attributes but it makes me excited -
Hey guys ! I'm currently doing a RBD project and I was wondering if you guys had any tips on how I can make my sim more optimised so that it doesn't take 25 min for only 10 inactive frames. The fracture is pretty low res and all the substeps settings are low but the sim is still really slow and prac...

Hi everyone, I need to switch low res pieces for high res ones. Unfortunately, only for this one object, the transform matrix is empty when coming out of the dop network. The other object coming out has a perfectly working matrix What could be causing this?

I am doing a custom force (magnetic like force) in dopnet for a bunch of instanced rigid body objects. The code in my VOP force node loop through other instances and apply forces if any is nearby. I found out my simulation is really inefficient and only utilizes a single CPU core. Is there...

i am trying to use the volume gradient - volume sample method to keep moving particles inside a volume. The particles move freely with a noise but as soon as they reach the edge they should turn. Doesn't seem right so far sdf_bounds.hip

Is it possible to access primintrinsics in dops? I have Geometry wich is transformed by a sim. For the second rbd sim i want to make the geometry look at a particular direction. For example to its original direction. So I deleted all Attributes from the first sim to prevent side effects and connecte...

I am working on a pyro sim in which i have cached every frame as a .sim file. These are very large, so ive been researching ways to cache the frames more efficiently. This led me to using the Dop I/O to cache out much smaller .bgeo.sc files. I am aware that this enables me to select which field...

Can somebody please help me with this surface tension problem. I have a scene and i want a different surface tension to apply to different group as show above. I want the group 1 to have higher surface tension and group 3 to have a lower surface tension but my setup is not working . SurfaceTens...

Hey everyone, so after my very long thread (https://forums.odforce.net/topic/44053-implement-kernel-maths-in-vex/) I finally found a solution. The setup works great at 0.05 res, you might have to dive inside the solver and change some parameters to get it work at other resolutions (especially...

I'm working on a POP simulation for a rainy window and I've set up the simulation so that source particles (in yellow) fall with erratic motion due to a varying POP Wind force and Gravity force, emitting a stream of particles behind them (in green) as they fall using POP replicate. The emitted parti... -
Helllo, I am new to houdini and trying to experiment with rbd but I fail to use the dop import node properly. I am trying to fetch the geometry of the dopnet inside an sopsolver. What am I doing wrong ? Thanks in advance.

Hi all. This should be easy, but it's killing me... I have a control object living outside a DOP network, a simple particle system. I've plugged it into the second input. Inside the DOP I access this control position without issue, in a VOP. However I then want to follow up by...

OK I read the section , Thank you for informing us about broken group and sop solver DOP , but how can we do that? I need to know about workflow.

Hi there, I'm trying to understand Dopnet a bit more in depth and try to understand a bit better how you can transfer data from one object and use it in another. While playing a bit around I ran into a problem where I don't understand why this isn't working. I created a simple particle setup,...

Hi, I was wondering if there is a way to distributed sparse pyro simulation. You can easily distribute with legacy pyro by distributing the container by slicing. I mean yeah... there is a predefined container that gets sliced in legacy but sparse create bounds on demand that is why it can...
