Blender Compositing

Overview

Build node-based compositing pipelines in Blender using Python. Set up render passes, add post-processing effects (blur, glare, color correction), combine layers, key green screens, and output final composited images — all scriptable from the terminal.

Instructions

1. Enable compositing and set up the node tree

import bpy

scene = bpy.context.scene
scene.use_nodes = True
tree = scene.node_tree
nodes = tree.nodes
links = tree.links
nodes.clear()
