One node, built properly

Every tool here started as a setup I'd rebuilt one too many times — a pile of wrangles and attribute adjusts that got copied from shot to shot until it was worth doing once, properly, with real controls and viewport feedback. They are deep rather than broad: fewer nodes, each of which does an entire job.

RPLidar In in Houdini

Free tool

RPLidar In

Bring live Slamtec RPLIDAR point-cloud data into Houdini as SOP geometry — stream, record, visualize, and drive live simulations.

  • Live sensor to SOP geometry, or replay it with the hardware unplugged.
  • Blob tracking with stable ids, so a solver reacts to the hand.
  • One button builds a POP network wired to the live points.
  • Cull everything outside a ground rectangle you drag like a Grid SOP.
See RPLidar InDocumentation
Neonyte in Houdini

Houdini HDA

Neonyte

Procedural neon signs for Houdini. Click a wall, press one button, and every placeholder becomes a different lit sign, with the metal rig behind it and a Karma material.

  • Every placeholder becomes a different finished sign.
  • Names from 34,217 real establishments, in five scripts.
  • Click a wall to place a sign; edit or erase any sign the same way.
  • Type a note, press the button; runs offline and deterministic.
See NeonyteDocumentation
Advanced Velocity in Houdini

Houdini HDA

Advanced Velocity

Author @v for simulations on one node — basic, directional, exploding, motion, curl noise and angular velocity, each with the same Adjust and Mask controls.

  • Six velocity types on one node, blended by a real mixer.
  • A whole timeline of velocity events, played back as one.
  • Drag on the mesh to place the blast source; the pieces tint live.
  • Ballistic Motion, plus Return to Home on a single slider.

Questions

Before you buy

Will these load in my Houdini?
They ship as .hdalc, the asset format of Houdini Indie and Apprentice. Commercial Houdini FX or Core can load them too, but doing so switches that session to limited-commercial (Indie) mode. That's SideFX's licensing rule, not a choice. Check how that fits your licence before buying; it's the one thing that catches people out.
What Houdini version do I need?
It varies by tool and each product page states it. Broadly: anything new is built against Houdini 22, and a couple of the older tools also run on 21. Windows is the tested platform.
What if I need a studio licence?
Currently only Houdini Indie HDAs (.hdalc) are available on Gumroad, but contact me for a custom solution at [email protected].
How do I install one?
Drop the .hdalc file into your otls folder and restart Houdini. The node then appears under Tab ▸ JV. When you update, delete the old file first — two versions of the same asset in one folder will collide.
Do I get updates?
Yes, free, for the life of the tool. Each node checks quietly on its own and tells you when there's a new version waiting on Gumroad — no mailing list, no phoning home for anything else. Grab the new file and replace the old one.
Can I look inside?
Mostly yes. Most of these ship unlocked, so you can dive in, read the network and learn from it — that's deliberate. Reallusion Importer is the exception and ships black-boxed.
Where do I get help?
Every tool has full documentation here on the site, and there's a Discord for questions and support — the invite link is in the Utilities folder on any JVtools node, so it always travels with the asset you own.
