NodeTree(ID)
Poll Function
The NodeTree.poll
function determines if a node tree is visible
in the given context (similar to how Panel.poll
and Menu.poll
define visibility). If it returns False,
the node tree type will not be selectable in the node editor.
A typical condition for shader nodes would be to check the active render engine of the scene and only show nodes of the renderer they are designed for.
import bpy
class CyclesNodeTree(bpy.types.NodeTree):
""" This operator is only visible when Cycles is the selected render engine"""
bl_label = "Cycles Node Tree"
