NodeIO, previously MaterialIO, is an import/export add-on for node trees. NodeIO allows things such as materials and other node setups to be saved to a file so they can be used later or distributed without having to share the whole .blend file. Currently, four different node systems are supported:
- Cycles nodes
- Blender Render nodes
- Mitsuba nodes
- Animation nodes (from the Animation Nodes add-on)
- Sverchok (Group Support Added)
This add-on is still in the early stage, especially when it comes to Animation nodes and Sverchok, so if anyone finds data that isn’t being exported and re-imported, or comes across any errors, then please report them at the link above.
