How to Convert any Molecule to PDB Format to use with ePMV in Cinema 4D

I’m writing this as a note to myself, so I’m only including just enough detail to figure this out again.

  1. Find the molecule on PubChem. For this tutorial, I’ll be using Sodium Alginate.
  2. Download the “3D Conformer” as an SDF file.

  3. Use OpenBabel to convert the SDF to a PDB file.

  4. Use ePMV in Cinema 4D to load in the molecule.
    1. Note: be sure to follow the installation instructions to the letter. You’ll encounter the error “no module named upy” if the ePMV folder is in a sub-folder in your plugins folder.

Free 3D Scan Models for Projects

One of the more common issues that I run into as a tutorial author is finding assets (models, textures, reference images, etc) that I can use and redistribute. Three D Scans (a project by Oliver Laric) is a wonderful resource for free Royalty Free high-quality models for render tests.
