Bake Node

Bake node.

The Bake node allows saving and loading intermediate geometries. This node bakes parts of the node tree for better performance.

The data format used to store geometry data is not considered to be an import/export format. Volume objects, however, are saved using the OpenVDB file format which can be used interoperably.

Important

  • Blend-files must be saved to a disk before data can be baked.

  • It’s not guaranteed that data written with one Blender version can be read by another Blender version.

Inputs

Geometry

Standard geometry input, which is used as the default bake item. More bake items can be added by dragging sockets into the blank socket or in the Bake Items panel. Items can be renamed by Ctrl-LMB on the socket name or in the nodes Properties panel.

Bake Items

Reference

Editor:

Geometry Node Editor

Panel:

Sidebar ‣ Node ‣ Bake Items

The Bake Items panel is used to manage the input sockets of the node thus also managing what data is baked.

Bake Items List

Used to manage the inputs and outputs of the bake node. Items can be added, removed, renamed, and sorted.

Socket Type

The data (Sockets) of the input/output.

Attribute Domain

The attribute domain used to evaluate the input field on.

Is Attribute

Bake item is an attribute stored on a geometry.

Properties

Note

Some properties can only be edited in the Properties panel (Sidebar ‣ Node ‣ Properties).

Bake Mode

The Bake node can calculate the geometry of a single frame or an animation.

  • Animation:

    Bakes the geometry data for multiple frames. By default the scene frame range is used, however, a Custom Range can also be defined.

    Still:

    Bakes the geometry data of the current frame.

Bake

Preforms all necessary geometry calculations and saves the data to disk.

  • Delete (Trash Icon)

    Deletes the bake data.

Custom Path

Specify a path where the baked data should be stored manually.

  • Bake Path

    Location on disk where the baked data is stored. Note, this path is also used for simulation zones.

Custom Range Animation

Override the simulation frame range from the scene.

Start, End

The start and end frame numbers for the custom range.

Outputs

For each input, the same output is added to act as a pass through.

Geometry

Standard geometry output, which is used as the default bake item. More bake items can be added by dragging sockets into the blank socket or in the Bake Items panel. Items can be renamed by Ctrl-LMB on the socket name or in the nodes Properties panel.
