Render Markers is an add-on that automates the process of rendering specific frames based on timeline markers. It allows users to render and instantly save only the frames that have markers assigned to them, bypassing the need to render entire sequences or sort through unnecessary images. The tool auto-saves each generated render directly to the designated Blender output directory. It is accessible from the Render menu and can be triggered using a customizable shortcut key. This workflow is particularly suited for storyboarding, comic creation, and Grease Pencil projects.
