## What it is
Molecular Nodes is a Blender add-on that imports and visualizes structural biology data such as PDB, mmCIF, molecular dynamics trajectories, and EM density maps. It leverages Blender's Geometry Nodes system to enable procedural styling and animation of molecules for scientific graphics.

## Use cases
- animate protein structures in Blender
- visualize PDB and mmCIF files in 3D
- play back molecular dynamics trajectories as animations
- render EM density maps in Blender
- create scientific illustrations of molecules
- style proteins with customizable molecular representations

## When to choose
- you need publication- or presentation-quality molecular animations
- you want to combine structural biology data with Blender's rendering and animation tools
- you work with MD trajectories, EM maps, or cryo-EM data and need 3D visualization
- you want procedural, node-based styling of molecular structures

## When to avoid
- you need a standalone molecular viewer without Blender
- you only need quick interactive inspection of structures (use PyMOL, ChimeraX, or Mol*)
- you don't use Blender and can't install add-ons
- you need quantitative analysis of structures rather than visualization

## Facets
- artifact type: plugin
