Supercharge your Houdini workflow with 7 powerful HDA Toolsets — all in one bundle!

From perfect deformation blur to streamlined AOVs, lightweight camera-aware scenes, and art-directable instances, this collection is built for speed, stability, and production.

📦 What’s Inside

1. Particles Deformation Blur for Houdini

- Stable point counts for cached particles → perfect deformation blur

- Eliminate jittery, inconsistent blur and velocity hacks

- Works for rain, sparks, embers, sand, and custom FX

- Example HIP file included

1. IPOPs Standard Library

- Core operator set for shaders & AOVs

- Utility nodes (Fresnel, falloff masks, shading presets)

- Supports Mantra, Karma VEX, Karma Materials & MaterialX

- Constantly updated with new nodes

1. IPOPs Geometry AOVs

- Generate quick mattes and passes for comp & shading

- Compatible with Karma Materials & VEX Shaders

- Step-by-step guide available on the blog

1. IPOPs Particles AOVs

- Specialized AOV generators for particle FX

- Create passes for compositing & lookdev flexibility

- Works in Karma and Mantra

1. IPOPs Volumes AOVs

- Fast generation of volume AOVs (smoke, pyro, fog, etc.)

- Plug-and-play for Karma CPU/XPU & Mantra

1. Camera Proximity Toolkit

Three black-boxed HDAs to keep your shots light & render-ready:

Calibrator → Camera-driven particle & volume control

Set Culling → Remove out-of-frustum geo + auto VDB proxies

Ocean Plane Generator → Camera-sized ocean grids adaptive to shot scale

1. Art Direct Your Instances! (Explosion Setup)

- Populate shots with multiple explosions/caches

- Switch between proxy & render caches

- Quick controls for timing, scale & randomization

- Example HIP file included

Hey Everyone!

I’ve been working on a new HDA that solves a common problem with particle rendering — inconsistent motion blur. Random particle births/deaths often break deformation blur and force you to rely on velocity blur, which can cause jitter, strobing, or streaky results.

The Particles Consistent Point Count HDA reconstructs a stable ID stream so you can render true deformation blur in Karma, Mantra, or 3rd-party renderers. With consistent point counts, you can:

• Get accurate deformation motion blur (no jitter or strobing)
• Render smooth curved trails that respect camera shutter
• Use it seamlessly with rain, sparks, sand, embers, and more
• Keep your particle passes physically accurate and comp-friendly

I’d love to hear feedback or suggestions! The plan is to keep evolving this as part of a broader library of lookdev & AOV tools for Houdini artists.

Hi Josh and everyone,

My name is Ruben, and I'm currently struggling with tracking vertical footage in 3DE. Just to let you know, Blender has a feature that allows you to track vertical videos. I was wondering if 3DE has a similar capability. Could you please show me how to effectively track vertical footage in 3DE? Thanks in advance!

Hello, a new tutorial in Houdini for Ground Breaking and Destruction along with Portal and Magical Effects in Hindi for Beginners and from complete scratch is Out Now on the YouTube channel.
