NoTime is a script for 3ds Max that toggles the time slider and track bar on and off. It's meant for moments when you're working on a still or just modeling rather than animating. Turning the two controls off is a single action, and turning them back on works the same way.
You can run the toggle as a toolbar button or as a quad menu item, so you can trigger it from either place. The current version is 1.
NoTime comes from Jon Seagull, a consultant and technical director whose work covers the technical side of client 3D pipelines, from technical direction on large or unusual projects to custom tool creation, scripting and emergency troubleshooting. NoTime is listed here as free, and a demo video is available. For the latest release and licensing details, see the developer's page.
