Blender Geometry Nodes Skill

Version: 2.0.1 Last Updated: 2026-10-10 Dependencies: Blender 5.1+

API Note (Blender 5.1+)

Use type='NODES' (not type='GEOMETRY_NODES', which was removed in 4.5):

import bpy
modifier = obj.modifiers.new("GeometryNodes", type='NODES')

bpy.ops works normally via the Blender MCP - use direct data API for explicit control, operators when convenient.
