Bioxel Nodes earns its place in the superhive library for bringing scientific volumetric data—DICOM, Nifti, Nrrd and more—into Blender through Geometry Nodes and Cycles, under an MIT license and across both Cycles and EEVEE.
Bioxel Nodes is a Blender addon from OmooLab for scientific volumetric data visualization. It uses Blender's Geometry Nodes and Cycles to process and render volumetric data, and it fully supports EEVEE NEXT.
The addon imports multiple formats, including DICOM, BMP, JPEG, PNG, TIFF, Nifti, Nrrd, and HDF5, and can bring 4D volumetric data into Blender. It offers a range of cutters along with simple and powerful nodes. Because the nodes are based on Blender natively, they can work without the addon.
Bioxel Nodes works with Cycles CPU, Cycles GPU (OptiX), and EEVEE. EEVEE NEXT support carries limitations: only one cutter is available, and the result is not as strong as Cycles. A section surface cannot yet be generated when converting to a mesh, and the roadmap lists a better multi-format import experience, one-click bake model with texture, and AI segmentation to generate labels. It is released under the MIT license.
Bioxel Nodes is best for scientific and medical volumetric data visualization in Blender.
Bioxel Nodes is completely free to download and use.
Bioxel Nodes lists support for Blender 4.2 and 4.1. It works with the Cycles render engine on CPU and GPU (OptiX), as well as EEVEE. When rendering with EEVEE NEXT, only one cutter is supported and the result is not as strong as Cycles. Note that the addon's older shaders are not based on OSL, so if volumes fail to render you may need to turn on Open Shading Language (OSL) in the Render Settings. Check the developer's page for the latest compatibility details.
Bioxel Nodes works with Cycles CPU, Cycles GPU (OptiX), and EEVEE. It fully supports EEVEE NEXT, though with limitations: only one cutter is supported, and the EEVEE result is not as strong as what Cycles produces. One current limitation is that a section surface cannot be generated when converting to a mesh, which the developer notes will be supported soon. See the developer's page for full details on render engine behaviour.
Bioxel Nodes supports importing several volumetric data formats, including DICOM, BMP, JPEG, PNG, TIFF, Nifti, Nrrd, and HDF5. It also supports importing 4D volumetric data into Blender. The developer's roadmap mentions a better multi-format import experience among the planned improvements. If you work with a format not listed above, check the developer's page to confirm current support before relying on it in a project.
Bioxel Nodes may break old files when the addon is updated, so a couple of steps help. Before updating, if a project is archived, running Bioxel Nodes > Save Staged Data makes the addon nodes permanent. After updating, old project files may not work if you had run Save Staged Data; in that case run Bioxel Nodes > Relink Nodes to Addon to resynchronise them with the addon's new functionality. Older shaders also predate OSL, so enable Open Shading Language in Render Settings if volumes will not render.
Bioxel Nodes is listed as free here and is released under the MIT license. Because pricing and licensing terms can change, check the developer's page for the current details before you rely on them. Worth knowing: the addon's nodes are based on Blender natively and can work without the addon, and if you are archiving a project you can run Save Staged Data to make the addon nodes permanent so they keep functioning independently of future addon updates.
