Thank you, John

Hi guys, In H19.5 I tried to use the Vellum Grain, but it doesn't show the grains as a sand sprite (as usual). How can I fix it? Thanks, for helping. Vellum Sprite.hip

Hi guys, I would like to get rid of the mushroom effect and add more and more small details to my pyro sim, but I don't know what parameters or fields are responsible for this. I tried "Disturbance", "Turbulence", "Velocity", "Gas Disturb", and "Gas Project nondivergent", ... without success! How can I fix it? Thanks for helping. Pyro.hip

Hi guys, I have two RBD objects, floating on FLIP-fluid. I set the Density (mass) to 400 (lower than the fluid mass). When two objects are of the same amount of mass, they have to react in the same way, right? I mean in this case, they have to stay on the surface. The problem is the bigger object stays on the surface, but the smaller one sinks into the fluid: - How can I fix it? - How can I set the density(mass) in the SOP level (as an RBD source)? Thanks for helping. Floating RBDs.hip

Hi guys, In a 2D shape, I need to retrieve the distance of every point to its boundaries, so I tried to use (a 2D) SDF, but it doesn't works properly. How can I fix it? Thanks for helping. Distance To Boundries.hip

Hi Lawrence, I need to use more than 50 objects floating in the water, so I can't use an RBD per object.

Hi guys, I tried to use "RBD Packed Object" + "FLIP fluid" and as you can see in the image bellow, the boxes sink into the fluid after a while. How can I fix it? The DOP creates some volumes inside the boxes, and I guess they are somehow a collision volume representation, but I don't know how to increase their resolution. As soon as the volumes disappear, the boxes sink into the fluid. Thanks for helping. Floating RBD Packed object_01.hip

In a CHOP network, how can I fetch geometry attributes?
Masoud replied to Masoud's topic in General Houdini Questions
Hi Tesan, Thank you for the reply. Honestly, I'm new to CHOPs, so the scene you sent me seems somehow complicated. I tried to use the "Shift CHOPs" node, but the value of the all points attribute are the same: CHOPs_Random Attrib 03.hip -
In a CHOP network, how can I fetch geometry attributes?
Masoud replied to Masoud's topic in General Houdini Questions
I tried the "For-Each" node, but there are still some issues! CHOPs_Random Attrib 02.hip -
In a CHOP network, how can I fetch geometry attributes?
Masoud posted a topic in General Houdini Questions
Hi guys, I would like to fetch an attribute from geometry and use it to change some parameters in the CHOP network. The idea is to vary (offset) a CHOP "Wave" phase parameter for each point of the geometry. Thanks for helping. CHOPs_Random Attrib.hip -
Any idea?

Hi guys, In a Vellum grain sim, I would like several chunks (clusters) to interact, but not stick to each other. As you can see in the image below they stick after the collision. How can I fix it? According to the documentation, there is an option in the Vellum Solver node called "Ignore Neighbors in Same Piece": https://www.sidefx.com/docs/houdini/nodes/dop/vellumsolver.html I tried to use this option, but it doesn't work. Thanks for helping. Vellum Grain_02.hip

Is there any DOP node (workflow) for Dynamic fracturing?
Masoud replied to Masoud's topic in Effects
I found this tutorial but it's a very complicated workflow: And somehow it tells me there is not a DOP node for such tasks, right?! -
Hi guys, I know how to use pre-fractured objects in an RBD simulation, but is there any workflow for Dynamic Fracturing? Thanks for helping.
