Surface Operators, also known as SOPs, are operators that can generate, import, modify and combine 3D surfaces (also called geometry). The surface types are polygons, curves, NURBS surfaces, metaballs and particles.


Sweet 16 SOPs

The following 16 SOPs are commonly used, we recommend familiarizing yourself with them.

Using SOPs

  • 3D geometry data, processed on CPU
  • Import: .fbx importer, File In SOP - recommend importing geometry from more mature modelers

All SOPs are documented in the Category:SOPs.
