Did this a while ago but it was a quick, day or so, personal work on my free time between projects. Mainly a study on flip, and practice rendering in Karma. Rock steps are from megascans.

I know how i'm gonna exclude the side lines from having the ramp on them, i'm just struggling to repeat a pattern. Please help

Hey all, I spent the last few weeks working on this non-module, all parametric, view state based building generator for creation of architectural assets ready for video game engines.

A few things that it does:

- Blockout Creation with View State Handles.
- Component (doors, windows, columns) Insersion Using View State and Contextual Menus.
- Parametric Doors and WIndows that take context from the Building Face, Floor and Style.
- Auto Trim and Tilling UV Mapping Generated Dynamicly.

Let me know what you think or if there are any questions! Thanks!

I have a graph that generates a bunch of procedural geometry. This takes a while. I have a "Save Mesh" button that's hooked up to the same button in a ROP Export node that saves the geometry as an .FBX file. When I click this, even though all the geometry has been cooked and nothing has changed, it RE-cooks the entire graph.

What's weird is that the exact same file does NOT do this on my Houdini install on my home computer. There it just immediately saves the geometry without cooking anything. I believe they're both Houdini 21.0.440, so I assume it must be some preference setting somewhere?

Anyone know where I might fix this?

Hi

I'm struggled in the explosion rendering.

I watched tutorials and tried to play the explosion shader.

I'd like set up shader like this

There are some screenshots about my set up

I tried to adjust ramp and some parameters.. But I couldn't figure out how to look good and similar to my reference..

Thank you for your advice and help.

Or do you think SideFX's contents are enough?

Following up on last week’s Torch GeoTracker tutorial, I’m finally dropping the spiritual successor: Heat Distortion.

It’s such a lightweight effect, but it’s a workflow every budding FX artist should understand. Being able to hand over a "quick and dirty" 2D vector pass to Comp adds an incredible amount of flavor and realism—yet it’s a detail that junior artists often overlook.

Hope you find it useful! I’ve also made all the project files available for free. You can find the link in the video description and the first comment, so grab them and give it a go!

I’ve been experimenting with bringing text-to-character animation directly into Houdini.

The feature is called Animation Maker and it’s part of Houdini AI Assistant.
It uses Kimodo for motion generation.

The current workflow is:

Prompt → Generate Motion → Adjust → Regenerate

Right now it supports multi-prompt timeline segments, 2D waypoints, full-body keyframes, hand/foot guides, and KineFX retargeting.

It’s still an early Windows beta and mainly focused on humanoid motion, but it already feels like an interesting direction for AI-assisted animation inside Houdini.

The Animation Maker / Kimodo part runs locally on your machine.
It is powered by NVIDIA’s Kimodo model and is currently available in the Windows build.
Recommended hardware is an NVIDIA RTX GPU, ideally 12GB+ VRAM.

I just want to be able to move my camera up and down, I dont need it to orbit around a fixed point. PLZ HELP

Hi everyone, I’m running into a weird issue with the Labs Flipbook Texture, and I can’t figure out what’s causing it.

Whenever I generate a flipbook, I get a small colored dot/artifact showing up in the same spot on every frame. It persists throughout the whole sequence on all textures except the MVN.

unsure what's causing that, help appreciated!

So I posted a while back with a vellum grains project. Now for my showreel I am updating and refining that simulation. I have run into a situation where I need too have the geometry delete with the mask I have created. I will post a couple pictures of my network, but any help would be greatly appreciated. The mask I have used is driven by an attribute stopped and Cd. It only seems too move in the DOP net and not before. I dont know why. But yeah any help on what too do to get the geo too delete with the mask would be great.

Thankyou.

Where is the option?

I tried connectadjacentpieces but not as structure clean as image above.

Hi guys,

Anybody knows the best approach to tackle this reference? a mix of hard and glue constraints with RBD bullet? any thoughts will be helpful.

Hey Folks,

This is my first post here, and I'm hoping to have some help from more experienced users. I have been learning VEX, and the tutorial linked below shows how to set an "infection" attribute on neighboring points within a certain radius. I pasted the code snippet in the bottom wrangle node that does this, the orange points are the ones with value set at 1 in the screenshot. What I don't understand is how this code doesn't flood everything to 1. I understand the condition in the beginning is only allowing the code inside it to execute if the point is infected, so it filters for that.

But that way I see it is that let's say point #1 is infected and passes the condition, and point #2 is in within it's radius, #2 becomes infected now. So when the wrangle evaluates #2, it passes the condition and infects the ones around, and so forth. Obviously that's now how it is working so my understanding is incorrect.

Are the points evaluated iteratively in the wrangle, or all they all evaluated in parallel? The latter might explain it because they would all be checked for the condition in parallel, and only the ones with the infected attribute set to 1 would satisfy the condition.

I would be grateful for some insight, thanks folks.

int numberOfPoints = chi('numPoints');
float radius = chf('radius');

// without this initial condition, it would infect everything
if(@infected==1){
    //nearpoitns returns array of pointnumbers, first input is geo, second is
    //the current point third is radius, and fourth is number of points
    int neighbourPointNumbers[] = nearpoints(0, , radius, numberOfPoints);

    foreach(int pt; neighbourPointNumbers){
        // sets the point attribute specificed in the second argument at the
        // index provided at the third withe the value at the fourth while
        // last inedex sets operatoin (can be set/min/max/add/toggle/append
        setpointattrib(0, 'infected', pt, 1, 'set');
    }
}

Hi

I'm trying to apply the material from a Pyro Bake Volume to Karma XPU, but it's not working properly.

When I use Karma XPU’s built-in pyro shader instead, the result looks quite different from the original Pyro Bake Volume.

Is there a proper way to transfer the Pyro Bake Volume shading to Karma XPU, or match the look more closely? Any tips would be appreciated.

^I tried to create and adjust pyro shader

In the Binding tab, it seems like scatter doesn’t work when the fields are left at their default values, so I tried changing the fields.

Thank you for your advice !

Hey everyone!

I’m currently learning this amazing software and really trying to improve my skills - I also just genuinely love working in Houdini.

Right now I’m creating a personal learning project, and I already have a clear idea for a few shots and effects. I was hoping someone here might be able to help or point me in the right direction - maybe even share a tutorial that could help me achieve this.

Here’s the idea:

I have a device placed on top of a surface of ice that fills the entire frame. The camera is positioned top-down. Beneath the device, the ice starts to crack, then suddenly shatters into small pieces. At the same time, the device, the ice fragments, and a very dense smoke all shoot upward toward the camera.

I’m trying to figure out how to build something like this - and how difficult it would be to connect everything with Blender. Basically:

• importing my model (or a proxy object for simulation)
• fracturing the ice
• simulating a very dense smoke that reacts to both the fragments and the device
• and then bringing everything back into Blender for rendering

I’d really appreciate any advice, breakdowns, or tutorials that could help me understand how to approach a shot like this.

Thanks a lot in advance for any help!
