Compositor Nodes in Python

Trigger

Use this skill when the user:

• Builds, edits or inspects compositor nodes from a script
• Mentions scene.node_tree, scene.use_nodes, compositing_node_group, CompositorNodeTree, CompositorNodeGlare, CompositorNodeRLayers, or CompositorNodeComposite
• Hits AttributeError on scene.node_tree after moving to 5.x
• Sets glare.glare_type / glare.quality / glare.size on 5.x and gets AttributeError
• Wants bloom and reaches for scene.eevee.use_bloom (removed in 4.2, absent on 4.5 and 5.x)
