BLACK FRIDAY SALE! FIRST 25 CUSTOMERS GET 25% OFF - USE CODE * PRO10 * AT CHECKOUT

TrembleFX is a pair of OBJ and SOP HDAs that generate CHOP-based motion noise with one click. Add natural sway, vibration, drifting movement, or full chaotic shake to any object, camera, or piece of geometry without touching a keyframe or a CHOP network.

Fast + Artist Friendly

Pick a preset, toggle which axis you want to move, and tune sliders like Amplitude, Speed, Harmonics, Smooth, Multiply, Noise Type, and Random Seed. Everything updates instantly in the viewport.

Preset Library

Includes a wide range of motion styles:
Sway, Vibrate, Pulse, Drift, Run, Twitchy Rotation, Chaotic, Security Cam, Steady Walk, Steady Crane, Ease & Hold, Gallop, Jackhammer, and Custom for full control.

OBJ + SOP Workflows

• OBJ (driving node): Perfect for cameras, props, characters, environment assets, or handycam-style movement, simply apply it before your object.
• SOP (driven node): Offset animations on individual pieces inside For-Each loops using random seed, speed or whichever value you like, use it manually or apply to scattered objects, debris, or mograph-style setups by applying it after your objects.

Looping + Stylised Motion

Use clean noise or sine modes for:

• Loopable animations
• Idle cycles
• mograph motion
• Subtle realism or stylised jitter

Fully Editable

TrembleFX is a HDA with a simple to follow chop network inside. If you want to go deeper, open it up and customise the CHOP networks, build new presets, or expand the logic.

TrembleFX has been tested in Houdini Indie 20-21+
