Installation

  1. User Preferences → Addons → Install Addon... ("Install From File" in 2.71...)
  2. Use the File Browser to find materials_cycles_converter.py on your hard drive
  3. Select the file and click "Install Addon..."
  4. Use the Addon browser to find and enable Materials Converter (it's in the Material category)

Purpose

Convert all non-nodes materials in the Blender Internal scene to Cycles materials at once.

Features:

  • Node combinations for diffuse, transparency, translucency, glossy, reflection, emit
  • Image texture support

Usage:

  • The UI consists of three buttons:
    • Convert All To Cycles: Convert all materials in the scene from non-nodes to Cycles
    • Convert Active to Cycles: Convert the active objects material to Cycles
    • Back to Blender: Switch Back to non nodes & Blender Internal

Tricks:

  • Some handy things noticed whilst testing.
    • Uv Unwrap in BI & set texture mapping to uv before Converting to Cycles. The UV mapping looks like it's respected even thought he Addon does not add Texture Coordinate or Vector Mapping
    • Switch back to Blender non node materials then make changes to materials in bi & convert again, updates the material rather than creating a new slot. This works one way only from Blender back to Cycles.

Known limitations:

  • No support for subsurface scattering
  • No Support For Blender Internal Nodes
  • No Support For Blender Internal Textures.
Additional information

For new materials making them directly in Cycles gives the best results. This script is meant for converting old scenes automatically to Cycles or can be used well importing uv mapped models into Blender Internal & converting them to cycles immediately
