Hey all, I'm attempting to find the number of unique values across the intrinsic:typename attribute for incoming geometry, but I'm having no luck in getting the uniquevals() function to detect any intrinsics. Originally I assumed that this was just a limitation of the function, but I then reali...

Hi everyone, I'm working with a point cloud and trying to select the boundary (or inverse boundary) points using VEX, similar to the image below. My code works well when the points are not too close to each other, but I encounter issues when the points are very close, like in the image sho...

My whole end goal is essentially just trying to take a Transform SOP's pivot rotation (visually shown in the viewport as the transform pivot handle) and extract it as a vector. This way I can then apply this rotation pivot vector to future transform SOPs to effectively copy the rotation pivot across... -
Hi everyone, Could you please take a look at the image below? I'm working on scaling a curve (which isn't at the origin) using VEX code. I need the scaling to be based on point number 0 (@ptnum = 0). Does anyone have any ideas or suggestions on how to approach this? Thanks in advance!...

Trying to reproduce this noise pattern from the MPM Advanced Avalanch example (left part of image circled in green) I think the issue might simple be one of scale. This is the vexpression @Cd = abs(float(snoise((@P*0.02+snoise(@P*0.02,5,0.5,1)),5,0.5,1)));...

Hi) Can I somehow get the maximum(and the minimum) value of an attribute in VEX? I want to use them in a FIT function.

Introducing the VEX Manager, a user-friendly tool which is an alternative from the existing Recipes, Gallery or Preset Dropdown Menu within Houdini. This tool is built solely for managing and editing VEX expressions while also storing notes within a light-weight python shelf tool. Simply...

Hi, I have a box with uv on it and bunch of points with different scale attribute on each point. Box size is (1,1,1). After copy to point operation, boxes resizing and uv stretching as expected. My question; is there any way to correct stretched uvs using present scale attribute without r...

Hi guys, Please take a look at the image (and the scene file) below. I need a vector attribute on the all points scattered inside the cylinder, which be pointed (toward) to the path. Any ideas to make this? Thanks for helping. Path.hip

Hi, I have recently created a set of 70+ HDAs called the IPOPs that aim at creating AOVs, Mattes & features for rendering. IPOPs are operator workflows designed to streamline shaders and AOV development in Houdini. With our toolset, artists can easily standardise their networks and access speci... -
Hi all. I made something a few weeks ago that I thought might be useful, so I somewhat tutorialised it here: http://www.pixelninja.design/manhattan-voronoi-approximation/ Basically it's a method of achieving something close to a Manhattan-distance voronoi diagram. I hope s...

A noob grains upres question here… I created a massive fracturing grains sim with Vellum at a low-ish resolution, and I'm using the grains' velocities to drive smaller dumber particles. When using the POP Advect by Volume, the particles are pushed around correctly as expected...

I'm trying to create a Vector parameter using VEX on an Attribute Wrangle. None of the channel functions, including chv() seem to work. Does anyone know why?

I'm leaving this file here in case you want to sort the point order of a triangle sphere. Its not particularly usefull but I was tasked with that challange and thats what I came up with... Hope it helps, and if any of you has a better method feel free to share! sorting_a_triangle_sphere....

These are some basic ideas that I used when creating the Saliva for movies like Hellboy (2019) and Manikarnika: Queen of Jhansi (2019). The main goal was to be able to Art Direct everything anytime as there were over 14 shots where the Supervisor and Director had very specific notes. Visit my blog f...

Getting closer to a new surreal idea I had in mind for a long time...Walls with Eyes! Here is my initial test for a small section of the wall. hoping to add in more detail and deformations to the rig the wall skin rig. I made the entire model and rig process combined into a single HDA. May need to o...

LookAt Setup in SOPs, VEX, VOPs. Having used the Houdini default tools several times, I wanted to achieve the same effect in SOPs. Here is a detailed post to understand better how the LookAt works and how it can be used in creative ways https://www.sharanvaswani.com/single-post/2020/09/27/Using-VEX-...

Hi everyone, after using rhino/grasshopper, and blender for a while, I just decided to getting into houdini, so that's my quest. I would need to measure the distance between a curve and an object( the object is a pipe/tube, and a curve is an helix that goes along the tube), then copytopoints a...

Hi guys, I'm looking to get the best way to realise this kind of pic in a realistic way.. My scene is not bad but begin to be heavy.. maybe an other way?. https://www.istockphoto.com/fr/photo/cheveux-sous-microscope-gm497686734-79258025 Thank you for help Cheveux.hip

Hi guys, I'm looking for the simplest way to scale a geometry, using VEX (by an attribute) and I would like to be able to define the pivot position, too. I tried these codes. It works but I don't need the other transform parts (like Position, Rotation, and ...): vector t=chv("Translate"...
