Inca

Inca is a free and open-source 3D modeling, animation, rigging, shading, and rendering application for Windows, Mac, and Linux. It mimics the Maya 2020 workflow, supporting polygon and NURBS modeling, animation with skeletons and constraints, material creation in a hypershade, and physically based rendering. Inca is scriptable via MEL or JavaScript and aims to provide a complete 3D production pipeline in one desktop app.
