Motion Trails Pro
Editable trails, arc analysis and spacing diagnostics.
Motion Trails Pro — hero loop
Overview
Motion Trails Pro draws the path your animation is actually travelling and diagnoses what is wrong with it. Trails are editable, sub-frame-accurate, and can be coloured by velocity, so spacing problems become something you can see rather than something you infer from graph editor tangents.
What it solves
A straight line between frames hides the truth about an arc, and spacing issues are hard to read in the graph editor. Motion Trails Pro samples between frames and overlays the arc the motion is reaching for, so you fix the cause instead of hunting the symptom.
How it works
- Turn on a trail and read the arc the camera actually sees, sampled between frames.
- Colour by velocity to make spacing changes and hitches obvious at a glance.
- Compare against the ideal arc overlay to see how far off the motion is.
- Follow the in-viewport markers to the exact frames where the arc breaks.
Motion Trails Pro concepts
- Sub-frame sampling
- The trail is sampled between frames, so what you see is the real path, not a straight line drawn between keys.

FAQ
Questions, answered.
Which versions of Maya are supported?
Maya 2022 through 2026, on Windows and Linux. The Qt shim layer handles PySide2 and PySide6 automatically, so the same install works across versions.
Do I need to be online to use ROM AnimTools?
No. Pro licenses carry a 30-day offline grace period. Your tools keep working on set, on a plane, or behind a studio firewall.
What happens to my files if my subscription lapses?
Nothing. Paid features lock, but your pose libraries, brushes, and drawings are yours and stay on your disk. You fall back to the Starter bundle.
Can I use one license on more than one machine?
Yes — Pro includes seats you can activate and deactivate yourself from your account, so a desktop and a laptop are no problem.
