【Blender×Python】ワールドデータを名称で取得する方法について徹底解説

# worldsプロパティによる名称を用いたワールドデータの取得
bpy.data.worlds[WORLD_NAME]

bpy.data.worlds[WORLD_NAME: str]
→ World: bpy.types.World

import bpy

SampleWorld = bpy.data.worlds["World"]
print(f"World:\n{SampleWorld} {type(SampleWorld)}")

print(SampleWorld.name)
print(SampleWorld.name_full)
print(SampleWorld.node_tree)
print(SampleWorld.node_tree.nodes)
print(SampleWorld.node_tree.links)

for key, value in SampleWorld.node_tree.nodes.items():
    print(f"[{key}] {value}, {value.type}, {[value_input.name for value_input in value.inputs]}, {[value_output.name for value_output in value.outputs]}")

for key, value in SampleWorld.node_tree.links.items():
    print(f"[{key}] {value} {value.from_node.name} ({value.from_socket.name}) -> {value.to_node.name} ({value.to_socket.name})")
