What is it?

Molecular Nodes (MN) is an addon for the 3D modelling & animation program Blender that enables easy import of molecular data such as .pdb & .mmCIF. MN also provides a number of pre-built Geometry Nodes for manipulating and creating animations from the underlying molecular data.


  • Download structures directly from the PDB using the 4-letter codes

  • Open local .pdb & .mmcif files

  • Open multi-state .pdb files and animate them as trajectories

  • Open molecular dynamics trajectory files such as .xtc & .dcd

  • Provides a suite of nodes for artistic manipulation of molecular data inside of Geometry Nodes
