Make movement feel intentional — not robotic
Most planners can find a route.
But that does not mean the motion feels good.
In XR, simulation, and real-time interactive environments, raw path output often creates movement that is:
- sharp
- jittery
- reactive
- visually robotic
- uncomfortable for camera-attached or player-observed motion
EchoPath Smooth is designed to solve that problem.
It upgrades raw path output into smoother, more stable motion while preserving the value of your current stack.
You keep your planner.
EchoPath Smooth upgrades the motion quality.
What EchoPath Smooth does
EchoPath Smooth is a motion-quality layer that sits on top of planner-generated waypoint paths and improves how movement is expressed in real time.
It helps:
- smooth NavMesh paths
- refine A* waypoint output
- stabilize custom planner motion
- reduce visible curvature spikes
- reduce abrupt motion changes
- generate cleaner movement rails
- improve comfort in XR and camera-followed systems
- preserve more stable path behavior during updates
This is not a planner replacement.
It is a motion upgrade layer.
Why this matters
Most navigation systems optimize for:
- shortest distance
- valid route finding
- fast solve time
They are not built to optimize for:
- motion comfort
- continuity
- stable curvature
- low-jerk updates
- believable movement quality
That is why so many agents move correctly but still feel wrong.
EchoPath Smooth exists to close that gap.
It converts route output into motion that feels more deliberate, more stable, and more natural — especially in environments where comfort and visual polish matter.
Best use cases
EchoPath Smooth is especially useful for:
- XR locomotion systems
- AR creatures and guided agents
- VR NPC motion
- third-person camera-follow experiences
- simulation and training environments
- robotics prototyping in Unity
- polished gameplay movement
- reactive or obstacle-rich scenes
If motion quality affects immersion, EchoPath Smooth is relevant.
How it fits into your workflow
Typical workflow:
- Generate a path using NavMesh, A*, or your own planner
- Pass the waypoint output into EchoPath Smooth
- Execute a cleaner, more stable motion path
No engine rewrite.
No planner replacement.
No lock-in.
EchoPath Smooth is built to slot into your existing Unity workflow as a practical motion layer.

Recommended first test
Before using EchoPath Smooth in production:
- Open the included demo scene
- Compare the raw path against the smoothed result
- Adjust smoothing parameters
- Confirm expected motion behavior in your target setup
This is the fastest way to verify installation and understand how the system behaves in practice.

What’s next
EchoPath Smooth is the first release in the EchoPath XR product stack.
Planned expansion includes:
- additional smoothing controls
- performance optimization updates
- Pro and Studio tiers
- future integration with broader EchoPath pathing and spatial systems
EchoPath Smooth is where the stack begins: motion first, pathing second, smarter spatial behavior next.
Is EchoPath Smooth a planner replacement?
No. EchoPath Smooth is a motion layer that improves the quality of planner-generated movement. It works on top of NavMesh, A*, and custom waypoint systems.
Does it work with Unity NavMesh?
Yes. EchoPath Smooth is Unity-first and works with NavMesh-based workflows as well as custom waypoint planners.
Is this useful outside XR?
Yes. While it is especially valuable for XR and camera-followed motion, it also helps in simulation, robotics prototyping, AI agents, and any scene where movement quality matters.
Do I need internet access?
Only for first-time license activation.
What comes with the product?
The package includes the Unity package, documentation, Quick Start PDF, example files, and the Indie tier license activation system.
Is commercial use allowed?
Yes. The Indie tier includes commercial use rights for the licensed developer.
