Works instantly, fits right in
Auto-connected constraints, purpose-built presets, and mirrored collision editing cut trial and error. Python / Blueprint APIs cover batch tuning and QA automation, so the time you save goes back into expression.

PRODUCTS
Velura System Products.
Each product is an independent Unreal Engine (UE) plugin. Start with just the one you need — combine them, and the range of expression grows even further.
BETA+ / AVAILABLE SOON
Velura Physics
A character-sway physics plugin for Unreal Engine that balances setup efficiency with expressive power. From hair to skirts and capes.

VELURA PHYSICS
Velura Physics
BETA+ / AVAILABLE SOON ON FAB
Natural motion, under your control.
An Unreal Engine plugin for the full range of swaying elements — hair, skirts, capes, tails, and accessories —
bringing them to life quickly and satisfyingly.
DEMO MOVIE YOUTUBE / COMING SOON
03
CORE VALUE
Three strengths behind natural motion.
Simple controls, rich expression
The focused, no-guesswork UI stays as it is, while an evolved constraint structure and versatile anti-penetration measures cover everything from fine strands of hair to large capes.
See it, verify it
Preview animations right inside the Animation Blueprint. The Quick Controls panel gives one-touch access to pose, frame stepping, debug wind, and penetration checks — with debug rendering that matches play-in-editor (PIE), tuning is finished without ever launching the game.
04
SETUP & WORKFLOW
Works instantly, fits right in.
ASSET SHARING — settings become team assets.
Key parameters and collisions are aggressively externalized as assets. Reuse settings across characters, share them within your team, and reference the same asset from multiple Animation Blueprints.
From applying purpose-built presets to asset Export / Reload and mirrored collision editing — setup lives in one Details panel.
05
FINE CONTROL
Simple controls, rich expression.
Design the sway freely with curves
Stiffness, damping, friction, gravity, and nearly every other parameter can be tuned individually along a root-to-tip curve.
ADJUSTABLE PARAMETERS — a representative selection
| Stiffness | How strongly bones return to their original pose (rigidity) |
|---|---|
| Damping | How quickly the sway settles |
| Velocity Attenuation | Restrains the return velocity (prevents spring-like bounce-back) |
| Gravity Scale | How strongly gravity applies |
| Global / Local Inertia | Inertia from character movement and rotation — hair and tails flow naturally on turns |
| Angle Limit / Max Distance / Backstop | Limits on angle, travel distance, and sink-in |
| Contact Friction | Friction on contact (how much things slide) |
| Surface / Bending Constraint | Constraints expressing the twist and bending stiffness of cloth surfaces |
| Per-chain Override | Start from shared settings, then override only what each chain needs |
| Anomaly detection | Automatically detects abnormal angles and stretch ratios (Experimental) |
There are many more parameters and constraints than fit here — and nearly all of them support curve control.
06
PREVIEW & DEBUG
See it, verify it.
Debug-view toggles, animation preview playback / frame stepping, debug wind, and penetration checks — all gathered in a single panel.
AND MORE
Built for production — and then some.
Setup
- Purpose-built presets included — hair / skirt / cape / tail / ribbon
- 7 material presets — from Rigid to Silk, set constraint stiffness in one touch
- One-click collision generation from PhysicsAsset
Collision
- Sphere / capsule / tapered capsule / box / plane + edge collision
- World collision — interact with stages and props
- External actor tracking — collisions from guitars, weapons, and other actors are pulled in automatically every frame
- Edit collisions by mouse drag
- Mirrored collision editing — build one side and the other is generated automatically (one-click duplication of RootBone and collisions, too)
Stability
- Fixed substepping on by default — physics runs on its own steady 60 Hz clock, independent of rendering, so behavior stays stable under frame-rate swings. Works out of the box
- During fast movement, simulation steps are subdivided further to suppress jitter automatically (Experimental)
- Warm-up plus caps on translation / rotation deltas keep teleports from exploding
- SupportBone — suppresses skirt-through-legs artifacts without complex rigging
Production pipeline
- SimulationBlendWeight — blend physics with the source animation per bone / chain
- Swap settings dynamically in Sequencer — even per cut
- Reinforce precision with dummy-bone insertion / bone splitting
- Quick Controls panel — rendering, pose, wind, and penetration checks in one tab

ADOPTION
Adoption.
VIRTUAL LIVE
Adopted in a virtual live concert
Velura System was adopted end to end — from hair and costume sway to material expression and synchronized stage lighting.
* Title and footage will be published once publication approval is granted.
