Blender Add-ons
Professional molecular visualization addon for Blender. Import PDB, CIF, MOL files or fetch from online databases, visualize proteins and molecules in 7 styles, and export publication-ready renders for scientific journals.
Molecular Viz Pro brings professional molecular visualization directly
into Blender. Import molecular structures from files or online
databases, choose from multiple visualization styles and color
schemes, animate your molecules, and export publication-ready renders
for scientific journals.
File Format Support
Import molecular data from 5 standard formats:
- PDB — Protein Data Bank format with full metadata, secondary
structure, and multi-model support
- mmCIF — modern macromolecular CIF standard for complex protein
structures
- MOL/MOL2 — MDL Molfile with explicit bond connectivity (V2000 and
V3000)
- SDF — Structure Data Files with multi-molecule support and property
extraction
- XYZ — simple coordinate format for quick visualization
Online Database Access
Fetch structures directly from three major scientific databases
without leaving Blender:
- RCSB PDB — over 200,000 protein structures by PDB ID
- PubChem — millions of small molecules by name, CID, or SMILES
- ChEMBL — drug and bioactive compound database
Quick presets for common molecules — Aspirin, Caffeine, Ibuprofen,
Penicillin — let you start visualizing instantly.
7 Visualization Styles
- Ball-and-Stick — atoms as spheres connected by cylinder bonds, the
most versatile general-purpose style
- Space-Filling (CPK) — full Van der Waals radius spheres showing true
molecular volume
- Wireframe — thin bond lines only, fast rendering for large molecules
- Sticks — thick bonds without atom spheres, emphasizing connectivity
- Cartoon — protein secondary structure with helices as spirals,
sheets as arrows, and coils as tubes
- Ribbon — smooth backbone trace through alpha carbons for protein
overview
- Surface — molecular surface using metaballs for Van der Waals or
solvent-accessible representation
8 Color Schemes
- CPK — standard element coloring (carbon gray, oxygen red, nitrogen
blue)
- Chain — distinct colors per protein chain for multi-chain complexes
- Residue — amino acid type coloring (hydrophobic, polar, charged)
- Secondary Structure — helices red, sheets yellow, coils gray
- B-Factor — temperature factor gradient for flexibility visualization
- Hydrophobicity — residue hydrophobicity mapping for surface analysis
- Rainbow — gradient from N-terminus to C-terminus
- Custom — user-defined per-atom coloring
Secondary Structure Detection
Built-in DSSP-like algorithm automatically identifies alpha helices,
beta sheets, and coil regions from atomic coordinates — no external
software required. Used for Cartoon and Ribbon styles and secondary
structure coloring.
Animation
Bring molecules to life with built-in animation tools:
- Rotation — single-axis spin with configurable speed and easing
- Tumble — multi-axis simultaneous rotation for dynamic presentation
- Wiggle — atomic vibration effects simulating thermal motion
- Turntable — automatic orbiting camera around the molecule
Publication-Ready Export
Export high-quality renders optimized for scientific journals:
- Journal presets for Nature, Science, Cell with correct styling and
resolution
- Resolution presets from HD to 4K, square formats, and
journal-specific sizes at 300 DPI
- Poster sizes A0 and A1 at print resolution
- Output formats — PNG, JPEG, TIFF, EXR with 8 or 16-bit color depth
- Transparent background option
- Cycles and EEVEE render engine support
Material Presets
6 material styles for different presentation needs — glossy, matte,
metallic, glass, Nature journal style, and Science journal style. Each
controls roughness, metallic, specular, and transmission properties
for physically accurate rendering.
Performance
Automatic LOD system simplifies geometry for molecules with over
10,000 atoms. Material caching prevents duplicates. Configurable atom
and bond quality settings balance visual fidelity with viewport
performance.
Complete Periodic Table
97 elements from Hydrogen to Uranium with accurate atomic mass,
covalent radius, Van der Waals radius, and standard CPK colors. 20
standard amino acids with hydrophobicity values for residue-based
analysis.
Requirements
- Blender 4.0 or newer
- No external dependencies — uses only Blender built-in modules
- Internet connection required only for online database fetching
- Works on Windows, macOS, and Linux
