Sequence Loader earns its place in the Blender extensions library by bundling meshio, so mesh sequences in many formats load through a single add-on, while its just-in-time loading is designed to keep memory use down on longer sequences.
Sequence Loader is a Blender add-on from Stefan-Jeske that loads meshio-supported mesh file sequences. Built for Blender 4.2 LTS and newer, it loads all data just-in-time when the Blender frame changes, an approach meant to avoid excessive memory consumption across a sequence.
By default the add-on loads vertices, lines, triangles and quads. It can automatically extract triangle and quad surface meshes from tetrahedral and hexahedral volume meshes, and it imports scalar and vector attributes on vertices for visualization purposes. Any additional supported data is loaded as geometry node attributes that can be used for shading.
The add-on comes bundled with meshio, which handles geometric data from a wide range of mesh file formats. Confirmed support covers .obj, .ply and .vtk, though not every meshio format has been tested and some issues may still occur. It is published under the GNU General Public License v3.0 or later.
Sequence Loader is best for blender users loading meshio-supported mesh file sequences, including rendering simulation results, across formats such as .obj, .ply and .vtk.
Sequence Loader is completely free to download and use.
Sequence Loader is built for Blender 4.2 LTS and newer, which is the compatibility the developer confirms. It might also work with Blender 2.8 and later, though those less recent versions have not been extensively tested, so behaviour there is not guaranteed. The add-on can be added by dragging and dropping the downloaded file into Blender, or by downloading and installing it from disk. It requests file permission for its core job of loading files from disk. For current compatibility details, check the developer's page.
Sequence Loader confirms support for .obj, .ply and .vtk files, covering points, triangles and quads, plus automatic surface extraction from tetrahedral and hexahedral meshes. Because it comes bundled with meshio, it can load geometric data from many additional mesh formats that meshio handles. Not all of those formats have been tested, however, and some issues may still occur with untested ones. It also imports scalar and vector vertex attributes and loads other supported data as geometry node attributes for shading.
Sequence Loader loads all data just-in-time as the Blender frame changes, rather than holding an entire sequence in memory at once. This approach is designed to avoid excessive memory consumption while working through file sequences. By default it handles vertices, lines, triangles and quads, and it can automatically extract triangle and quad surface meshes from tetrahedral and hexahedral volume meshes. Scalar and vector attributes on vertices are imported as well, for visualization purposes.
Sequence Loader is listed as free in this catalog and is published under the GNU General Public License v3.0 or later. That license governs how you can use, modify and redistribute the add-on, so it is worth reviewing if you plan to build on it. The add-on itself is compact in size and available to download and install directly into Blender. For the current licensing terms and any updates, check the developer's page.
