I'm trying to fix:

bpy.context.scene.world.light_settings.use_environment_light = True
bpy.context.scene.world.light_settings.environment_energy = energy
bpy.context.scene.world.light_settings.environment_color = 'PLAIN'

to make them work in blender 2.8. I read Setting up a Sky: bpy.context.world = None, but my bpy.context.scene.world.node_tree is None. How would I set up a node tree and add the Background node?

It seems like the correct code should be something like bpy.context.scene.world.node_tree.nodes['Background'].inputs['Strength'].default_value = energy, but I can't figure out how to make the node_tree.

Any help would be greatly appreciated!

    $\begingroup$ Can you please explain what you actually want to do? Setting up a custom environment using a hdri or just a plain color and up the strength? $\endgroup$ – brockmann Feb 24 '20 at 9:15

    $\begingroup$ Once the world is created, just add something like: world.use_nodes = True This will create the node tree. $\endgroup$ – lemon Feb 24 '20 at 9:33
