Changes in the bpy Python API by the pynodes branch

  • Node identifiers have been changed. A node type now uses the same identifier string as the associated RNA type, instead of the upper-case enum identifiers. These strings are used when adding trees, nodes or sockets using bpy.data.node_groups.new, nodetree.nodes.new or node.inputs.new/node.outputs.new respectively.
Examples:
Node Trees:
bpy.data.node_groups.new('SHADER') -> bpy.data.node_groups.new('ShaderNodeTree')
Nodes:
nodetree.nodes.new(type='OUTPUT_MATERIAL') -> nodetree.nodes.new(type='ShaderNodeOutputMaterial')
nodetree.nodes.new(type='BSDF_GLASS') -> nodetree.nodes.new(type='ShaderNodeBsdfGlass')
nodetree.nodes.new(type='PIXELATE') -> nodetree.nodes.new(type='CompositorNodePixelate')
WARNING!
The node.type property still returns the old enum identifiers. This is necessary for compatibility scripts, but using the 'type' property is generally discouraged. To get the actual identifier of a node type use node.bl_idname
