How to Create a Cache with Blender Geometry Nodes’ Bake Node

What will you learn in this guide?

Geometry Nodes networks may need to generate calculated geometry repeatedly in the same scene. The Bake Node calculates and stores the output of a specific part of the node tree, allowing you to reuse that intermediate data later. This guide explains what the Bake Node does, how to manage bake items, how to store data for a single frame or an animation, and how to manage saved bakes.

Baking is not a general-purpose export method for transferring a model to another program. The Blender manual notes that the geometry data storage format is not designed as an import/export format. Volume objects, however, are stored in OpenVDB format, which can be used across different applications.

Requirements and preparation

The basic workflow requires a node tree that uses Geometry Nodes in Blender and a Bake Node. The sources do not specify a particular Blender version or system requirements for the Bake Node. It is therefore a good precaution to record the Blender version used for the project and use the same version across the team: according to the manual, there is no guarantee that bake data written in one Blender version can be read by another.

Before you begin, identify where in the node tree the data to be baked is generated. The standard Geometry input on the Bake Node is the default bake item. You can define additional input/output items to store other types of data. Manage these items in the Bake Items panel or by dragging a new socket onto an empty socket on the node. To rename an item, Ctrl-click its socket name.

Step by step: Configure the Bake Node

1. Add a Bake Node to the Geometry Nodes network where you want to store the calculated intermediate data, and continue the geometry flow through the node’s input. According to the manual, each bake item has a corresponding output, which lets the data continue through the network.

2. Review the Bake Items list. This section determines which input and output data the node will bake. Add the required items, remove those you do not need, and give them clear names. For an item with an attribute, the Attribute Domain setting also determines the domain on which the data is evaluated. The relevant setting controls whether the item is stored as an Attribute.

3. Open the Bake Node’s properties. Some options are configured in the Node > Properties section of the Sidebar in the Geometry Node Editor. The Bake Mode determines the scope of the operation: Still stores geometry for the current frame; Animation processes multiple frames.

4. When Animation is selected, the scene’s frame range is used by default. To use a different range, enable Custom Range and enter the start and end frames. This lets you define the bake range separately from the scene’s overall range.

5. Use Bake Target to choose where the data is stored. Inherit from Modifier takes the setting from the modifier that contains the Bake Node. Packed stores the data inside the .blend file. Disk stores it in a separate folder; Custom Path lets you specify the location manually. For disk-based storage, Bake Path shows where the data will be written. Simulation zones also use this path.

6. After checking the settings, run the Bake command. Blender performs the required geometry calculations and saves the data to the selected target. Use the Pack/Unpack options to pack an existing bake into the file or unpack it from the file. You can remove bake data you no longer need with the Delete Geometry Node Bake command.

Choosing a storage target and workflow

If sharing a scene as a single .blend file without carrying a separate data folder is a priority, Packed can be a practical choice. However, this may affect the file size. The Blender 4.3 release notes state that bakes are packed by default, that bake sizes can be viewed, and that very large bakes are recommended to be stored separately; separate files can be loaded when needed. The current manual, on the other hand, describes the default for Bake Target as inheriting from the modifier. So check the target setting in your project rather than assuming its default.

If you choose Disk or a custom path, you also need to move the relevant bake folder along with the .blend file. Keeping the folder structure consistent when sharing with a team helps reduce access issues when the file is opened on another computer. The lack of a guarantee for bake compatibility between Blender versions should also be considered in archiving and delivery plans.

Using Bake Nodes in architecture, interiors, and archviz workflows

In a scene with repeated geometry generation, storing an intermediate result can reduce the need to recalculate the same section every time the scene is evaluated. For example, when preparing repeated elements in an architectural model or procedural geometry tied to a scene, you could try baking stages that do not change. Any performance gain depends on the structure of the node tree and the scene; the sources do not promise a specific speed increase.

For an animated presentation, Animation mode is intended to store data across a frame range. Still mode may be sufficient for a single interior shot or a static model. When sharing files within an office, weigh Packed and Disk options against file size, folder management, and the Blender versions used by the team. This method does not provide any compatibility guarantees for render engines or hardware that are not stated in the sources.

The Geo Bake Batch add-on is also available for batch-managing bakes instead of handling each object individually. It offers options to bake missing caches on selected objects, rebake all of them, and clear caches. Blender 4.2+ is required; the relevant Geometry Nodes modifiers must also contain a connected and correctly configured Bake Node, and the .blend file must have been saved beforehand. Think of this add-on as an additional option for batch management, not a replacement for the basic Bake Node workflow.

Common mistakes and next steps

Adding a Bake Node is not enough on its own: make sure the geometry flow is correct and the items to be stored are defined. Overlooking the frame range for an Animation bake can lead to processing a wider range than necessary. When using a disk target, choose the storage path with the folder’s preservation in mind when moving the file. Do not assume that bake data will necessarily be readable when a project is opened in another Blender version.

If you use the batch add-on, check that you are not working with an unsaved file and that each target modifier contains a suitable Bake Node. As a next step, test Still mode or a short Custom Range on a small part of the scene. Once you have verified the target location and output, move on to a larger bake.

A September 2026 Geometry Nodes workshop post by Blender developers also discusses the idea of making bake buttons visible in the node group interface and on the modifier. This is presented as a development goal in the post; it should not be confused with the current basic Bake Node steps.
