Node Overview¶

Scene Assembler nodes are organized into four groups.

Collection nodes¶

These nodes bring objects into the assembly pipeline and let you filter or combine them.

Node	Purpose
Collection Source	Load one or more collections from the current file
External Collection	Load collections from an external .blend file
Extract Collection	Apply overrides to all objects in one or more collections
Extract Object	Pick a single object from a collection to start an override chain
View Layer (Merge Collections)	Define one view layer — combine collections, set per-layer overrides and Collection Flags

These nodes define what gets rendered and where the output goes.

Node	Purpose
Output Defaults	Set base output path, format, and filename tokens for all Scene nodes
Scene Node	Define a render job — collections, camera, render settings, overrides
Playblast	Quick viewport preview render (image sequence or video) — local only, not queued

These nodes configure how a scene is rendered. Connect them to the Scene node's input sockets.

Node	Purpose
Render Settings	Engine, samples, motion blur, and other render parameters
Render Passes	Enable render passes, AOVs, Cryptomatte, and light groups
World	Override the world (HDRI, background) for a render layer
Camera	Override the camera for a render layer
Camera Sequence	Switch between multiple cameras over an animation, driven from the node graph
Compositor	Attach a compositor node tree to the assembled scene
Freestyle	Configure Freestyle line rendering per layer

Override nodes modify objects in an assembled scene without touching the source data. Chain them between a collection/object node and the Scene node.

Node	Purpose
Shader Override	Replace a material slot on an object
Visibility Override	Show or hide objects in a specific render layer
Light Override	Change light energy, color, or other properties
Transform Override	Add a delta offset to an object's position, rotation, or scale
Animation Override	Replace an object's animation action
RNA Override	Set any Blender property via its RNA data path
Render Pass Format Override	Change the file format for a specific render pass

Node	Purpose
Set / Get	Store and retrieve values across node graphs
Timeline	Sequence multiple Scene nodes on a strip-based timeline
Scheduler	Send all connected Scene nodes to the queue in one click
