I am using an Attribute noise to scatter some moving points (via pointVOP) and would like to have a gradient mask from left to right to blend the noise on the points, any idea how I can achieve this? I have tried this with no luck: Any help would be extremely grateful.

(VEX) Connecting disordered points with lines
RUXERMAGNO posted a topic in General Houdini Questions
Hello, I need help to connect points with a single line without crossing it, the points are out of order so it does not work to use the Add node. I am trying to use For Each and arrays in VEX but nothing works for me. I have a "start" and "end" group with the correct points, I need to iterate fr...

Hey there, What approach would I take if I wanted to generate points inside a heightfield mask, where the points spread across the center of the mask? Thanks!

I'm still newish to Houdini, so please bare with me. I'm trying to create walls between multiple watertight objects of uncertain shapes, which are guaranteed to have space in between them, but which are still close together. My first idea was a 3D Voronoi structure kind of solution, a bit lik...

I've been trying to engineer this effect that I found in this video, timestamp 19:01. I think I understand everything but I can't figure out how to set up the CHOPs network in order to create this randomised resizing animation. The closest I could get was by animating the internal edges to...

Hello there I have a bunch of points in space and my team needs them to be in format .ply : Here my viewport I never worked with this format, how would you approach to export it in .ply? I dont really know if this is working properly, Houdini reads it okay in a file node and also Blend...

Hey all, I'm trying to recreate this trail-motion form-like thing... I was trying to do it with a sweep and a path but I'm not getting the nice interesting shapes like in the image. Does anyone else have an idea on how to approach this? here is my failed attempt so far (in the hip):...

Hello! I'm kind of new to Houdini and especially to VEX. I was trying to animate scales appearing on a geometry using a ramp in an attribute wrangle, which controls pscale. This way, when changing ramp point position pscale changes along the x axis. However, the last points don't change, as yo...

Hi, I'm trying to solve an interesting task in Houdini while I learn more about VEX and just ran into a situation where I'm not finding an answer anywhere. So, I created a voronoi sphere and then added center points on each "piece" (face) of the voronoi cells. What i'm trying to do next is...

Draw lines from one object's points to another.
Smicksus posted a topic in General Houdini Questions
Hi peeps, Maybe someone can help me achieve this. I followed a tutorial by Antengma on how you can make lines between points with a specific searchradius. (That is the code I'm using in the wrangle) Now for this particular setup, I want only the red points to draw lines between the blue point...

Hi Guys, I'm stuck doing this stuff, I would like to make a DNA based on fiber/curves like in the picture The 2 branchs and every step in the middle are noisy fiber.. I getted the DNA but can't get the way for the middle steps.. Any help would be appreciate. Thank you...

while pointvop only run over points, is it possible for the point to find out what's the prim number belongs to, and then retrieve a attribute from the prim? i am currently making: 1) attributes in a curve 2) promoting the attributes to points 3) using those attributes,...

I’m looking for a way to go about connecting points based on a min/max distance. My goal is to skip connecting the points closest to the starting point, and only connect to points within the minimum distance threshold.

Hello guys, As you can see in the image below, in a bunch of points islands, I need these things, using VEX: 1) I want to apply random color to each point island (cluster). 2) I want to group each cluster’s (averaged) center points. I tried several ways without success . I would...

Hi, I'm trying to offset points along a curve with a specific p vector... I'm pretty close but it seems to be shifting the point count randomly when it animates? You can see where the problem is in the screengrab.... Here is a test scene any advice or help would be much appreciated. pointsT...

Hello, I'm trying to wrap my head around this... how could I have the orient of nearby points (possibly with a falloff) point avoid (point away from) a nearby object? My setup right now consists of copied points on a surface and would love them to directional rotate away from the sphere as it...

Does anyone know if it is possible in H to conform one humanoid mesh to another? I'm really looking for a procedural method for aligning dimensions and orientation of a destination mesh with a base reference source mesh. I don't think I need a morph SOP, because the destination needs to re...

Hello, I am trying to reduce the curves of a groom object using VEX code in a point wrangle. This is the code I am currently using which is run over 'roots' to locate the nearest other root points and then to reduce curves that those points are in. float searchRadius = ch('searchRadius'); i...

Hi there! I have this melting setup with a POP solver, basically scattering some points onto the original mesh and then melting then and meshing back everything again using "particlefluidsurface". So I have been trying to get rid of this flickering on the mesh, I have over 500k points and...

Hello, I have a sim set up using flip objects with geo copied to points. I want to be able to delete 5% of my points every frame after a specific frame, so there is a gradual deletion. I referenced this post which triggers from frame 1. https://forums.odforce.net/topic/29024-delete-5-of-points-...

How to move points only on Y axis using noise?
carl45456 posted a topic in General Houdini Questions
Hello, I am scattering points onto a grid and I am using a noise to displace it, but I only want to move the points vertically. How would I achieve that?

Hello, I have a sphere where I am scattering points in the middle of each primitive, but the final output has the made all the cubes face in one direction. this is the desired outcome I want, but all the points here are scattered on each point but not on each primitive. A...

Hey everyone, I have an animated object moving in a sin wave type motion. I am trying to emit smoke outwards from it. At the moment the smoke is just rising in Y which isn't what I want. Any suggestions? + i made an awful unnecessary diagram, it might help or i...
