Microscopy Nodes earns its place in the Blender extensions library for bringing microscopy data import and visualization directly into Blender, from .tif and OME-Zarr files up to 5D. It has recorded over 14,000 downloads and updates through version 3.0.1.
Microscopy Nodes is a Blender add-on for visualizing high-dimensional microscopy data, handling datasets up to 5D — XYZ plus time and channels. It imports .tif and OME-Zarr files with any axis order, whether 'tzcyx' or a subset, and works with fluorescence, electron microscopy, and other imaging types.
The add-on lives in a panel under Scene Properties, where loading a file by local path or URL auto-reads its metadata and prompts you to define how each channel is visualized. Per-channel options include volume or isosurface rendering, label masks, emission, resolution, and colors. Colors can be picked per channel or set through non-linear LUT selection from many colormaps, and any object can be sliced by moving the Slicing Cube like any other Blender object.
A 3D scale grid and physical Blender scales support accurate representation and registration. For heavy data, you can build your animation on a downscaled version and render with the full dataset. Released under the GNU GPL v3.0 or later, it runs on macOS Apple Silicon, Windows, and Linux, and a YouTube tutorial playlist covers installation and common workflows.
Microscopy Nodes is best for scientists and anyone working with biological or microscopy images who want to visualize fluorescence, electron microscopy, or other high-dimensional datasets inside Blender.
Microscopy Nodes is completely free to download and use.
Microscopy Nodes is compatible with Blender 5.1 and newer, so it targets recent Blender releases rather than older versions. It runs on macOS Apple Silicon, Windows, and Linux. The panel is found in Scene Properties, where you load .tif or OME-Zarr files by path or URL. If you're on an earlier Blender build, check the developer's page before installing, since compatibility here is listed from Blender 5.1 upward.
Microscopy Nodes imports .tif and OME-Zarr (.zarr) files, and it reads any axis order, whether 'tzcyx' or a subset of those axes. It supports datasets up to 5D, covering XYZ plus time and channels. Once a file is loaded, its metadata auto-loads and you define how each channel is visualized — as a volume, surface, or label mask. It works across microscopy types, including fluorescence and electron microscopy.
Microscopy Nodes requests network permission to load OME-Zarr files from the internet using a given URL, so an internet connection is needed only when pulling data from a remote source. It also requests file permissions for importing data from disk and writing to a cache folder. Local .tif and .zarr files can be loaded by path without a network. Both permissions are declared for the extension on its listing.
Microscopy Nodes can be added by dragging and dropping the extension into Blender, or by downloading it and using Install from Disk. Separate downloads are provided for Windows, macOS Apple Silicon, and Linux. After installing, open the Microscopy Nodes panel in Scene Properties and load a .tif or OME-Zarr file by path or URL. A YouTube tutorial playlist covers installation along with loading data and creating renders.
Microscopy Nodes is listed as free here and released under the GNU General Public License v3.0 or later. For current licensing details and terms, check the developer's page. The add-on is available in Windows, macOS Apple Silicon, and Linux builds and has recorded over 14,000 downloads. If you publish work made with it, the developer asks that you cite the associated preprint referenced in the project's documentation.
