OBJSequence

OBJSequence lists compatibility with Blender 4.2 LTS and newer, so it runs on the current long-term-support release and later versions. The extension is at version 1.0.5 and installs like other Blender extensions, either by dragging the downloaded file into Blender or through Install from Disk. If you run a build older than 4.2 LTS, check the developer's page on Blender Extensions for the supported version range before installing so the import options behave as described.

OBJSequence adds an import entry under File > Import > OBJ Sequence. Select any OBJ file inside the target folder and the extension builds a single playable mesh that updates as you scrub or play the timeline. From the import options you can filter files by filename prefix, set the animation start frame, control frame stepping, and stream frames from disk using a cache so larger sequences are easier to work with. After import, each sequence is managed from the Stop Motion tab in the 3D View sidebar.

OBJSequence includes a File > Import > OBJ Sequence Folder option for batch imports. Choose a root folder that contains subfolders of OBJ files and the extension creates one animated sequence object per subfolder, which makes it faster to bring in several scan takes, simulation caches, or stop-motion clips in one pass. Each imported sequence can then be adjusted live, refreshed to re-read files from disk, or removed from the object through the Stop Motion tab in the sidebar.

OBJSequence is listed as free here and is distributed under the GNU General Public License v3.0 or later, which covers how you can use, modify, and redistribute the extension. For current licensing terms and any updates, check the developer's page on Blender Extensions. The download is small, around ten kilobytes, and installs through Blender's standard extension workflow, either by drag and drop into Blender or by choosing Install from Disk.

OBJSequence requests one permission: read access to OBJ files from folders you choose. It reads the OBJ frames stored in the target folder or its subfolders and updates the mesh sequence from those files on disk. Because it streams frames using a cache, it re-reads files when you refresh a sequence from the Stop Motion tab in the 3D View sidebar. The permission is limited to reading OBJ files from the locations you point it at during import.
