I have made a simple emitter of vellum cloth spheres. I now want to randomize the pscale of each sphere. I thought the best method would be to actually just randomize the pressure/ rest length of each sphere but im having no luck 2025-04-25 22-14-38.mp4 It looks like its workin... -
So here's my geometry : And then after appending the convert line SOP : Now i want to basically "undo" this and go back to having faces (for context i'm feeding these primitives into a grain simulation to tear it). So i tried with the Polyfill set to triangles but it outp...

flip Need help with improving this flip simulation.
1Necro1 posted a topic in General Houdini Questions
This is the simulation I'm currently working on, where the character interacts with a flip object as if entering it. The larger middle section represents the character's head, and the other two sections are the hands. Unfortunately, due to an NDA, I can't provide the flipbook with the character....thumb.png.4b89f96d71fcad477968d81350bb23b9.png)

Hey guys. Ive an hair guides on a sphere, It has a curl noise offset on X on the guides. In order to stick the root of the hair on the primitive I used curveu to mix the amount of noise, but the tip goes inside the geometry naturally. I not using dop, is there a way "collide"/offset t...

Hi everyone! Houdini noob here. Hopefully i can get some help hehe i know this is the forum of Houdini pros. Thank you so much in advance for any help/guidance you can give. I'm trying to make some vellum cloth floating, but i want to do an animation where it just loops floating. This is wh...

Hello all, I've been working on this setup for camera-space object silhouettes that will be used to conform/cull objects outside of them. While my setup is functional, it is sluggish...despite me trying to be quite performance conscious. I've prepared a simple example scene for you...

Hello guys. As title says, I'm created an grayscale procedural texture in Cops network. I'm made it work as displace map, however it comes as huge cost, needing an ultra high detailed grid. I'm would like to use it as bump, since the ideia it's to use that as fine details. I'm couldnt...

I have attached my Houdini file, containing my simulation for a paint along my logo. I am using FLIP Fluids and multiple collision objects. I don't think this is the best way, manually key-framing multiple objects against a flow object, and I don't know how to achieve a constant flow. Please give su...

Hello guys I'm building an lazy mood river I saw an reference that would fit exactly what that i need, it is something like those diffefent water flows. I'm wondering how to achieve this Pyro smoke 2d custom flow??

Not sure if there’s something I’m missing, but with each new version I find myself having to configure my settings all over again. Is there an easy way to transfer all settings to the new version like in Blender? I’m talking global settings, node presets, etc. Thanks!

Hi! This is my first post to this wonderful forum, my teacher recommended it to me since I'm the only one in my CG-course to want to work with Houdini and the autodidactic approach can be harsh sometimes I was following the classic "vex isn't scary"-tutorial on for loops and decided I wanted t...

Hey guys i tought that the pop collision detect sop would work in both pop solder and rigid bodies solver. i want that the rbd pieces sticky/stop when collide in a geomtry. however i have no ideia how to build that in rigid bodies. please help me stop_at_collision.hip

Hey guys, i messing a few days to achieve an fire spreading through a ceilling. like this reference: https://www.actionvfx.com/collections/ceiling-fire-stock-footage At first i thought that it would be easy, after a few days trying to reach the look, all my attemps were dull. i have no clue ho...

Hi all, so I am kind of new to rendering with karma and have come across an issue where the light interaction with the geo is looking weird. Have tried retopo of the geo which hasn't worked. Any help would be amazing

Hello guys. i creating an group to activate the pieces to start to fly. im using an sop solver in the pre-solve input to create those pieces active=1 However while move outside the region bound. it loss this attribute and simple stop. i tried to "hold" the attribute 1 using an m...

Hello, My aim is to be able to recreate an explosion made of objects (in this case pills), which collide with each other and move away and float without gravity in the opposite direction from the central point of origin "of the explosion. Does anyone have any idea how to recreate this... -
Hi! First, I would like to say that I have a very basic knowledge of the program's tools, I have a very superficial knowledge of the whole. Maybe I don't really have the ability to do what I want yet but I decided to ask for help here! My intention is to make a tree simulation using Lsystem and...

Hi everyone! I recently started working with the HDK and have been trying to set my project up to use an external library, but I don't have a lot of experience with dependency management in C++. It seemed to me like setting something up with a cmake file was the way to go, but I'm having a hard... -
I had this problem with my own project and decided to try a simple tutorial if the same problem would occur. It is a simple fracture animation exported as fbx to unreal. This is the tutorial https://www.youtube.com/watch?v=dVgKpOYo-4Q&t=5s and the problem is in the picture. The sphere is smooth in H...

Hi guys/ladies, how can I compute a proper vector field that's tangent to any arbitrary mesh in VEX? I used the polyframe SOP but there are some inconsistencies with the vector directions and plus I'd love to know a VEX approach for creating a proper tangent field on arbitrary mesh. Thanks in advanc...

Hey there, So I have been looking around on various posts to try and find out how I take my template scene file and make so whenever I open a version of Houdini that template file is the one that opens. I know very little about scripting and I am not sure what I am meant to change...

I am a person who uses Houdini 18.0.499 version. As far as I know, if you press the question mark while wearing a hoodie, a help window will appear in html format. However, if you click the question mark on my computer, you can't find the page as shown below. The results came out, but I can't fi...

Hi All, for my uni project created this satellite destruction. I have attached the billowy smoke pre-set to the Debris source and it does not show in viewport or render view? But as I don't have any error messages I can't figure out why it won't show... All and any help in the right direction would...

Hello, I'm brand new to Houdini and have been working on a "shockwave" effect and I have just looked in the Render View and there was only black screen. Then I tried to actually render it but it would still only show a black screen. I've attached some images below to show the issues that I...
