Why we like it

Randomize Noise Offset fills a specific gap: Blender ships no operator for batch-randomizing the Offset of Noise F-Curve modifiers, and this add-on adds exactly that. At 2.4 KB, it is a focused, single-purpose utility rather than a broad toolkit.

What is Randomize Noise Offset?

Randomize Noise Offset is a compact Blender add-on from a.a.andrusenko that randomizes the Offset parameter of all Noise F-Curve modifiers on the active Actions of selected objects. If no object is selected, it works on the active one instead. The offset is defined in seconds and automatically converted to frames using FPS, and a Seed field keeps results reproducible across runs.

Blender has no built-in operator for batch-randomizing the Offset of Noise modifiers, so the change otherwise has to be made manually for each curve. This add-on applies the randomization across many curves at once, which can help de-sync repeated Noise patterns across objects for more natural motion. You set a Seed and an Offset Min/Max range in seconds, then run it from the Graph Editor.

The tool lives under Graph Editor → N → Modifiers → Randomize Noise Offset. It is self-contained, requires no special permissions, and calls no external services or scripts. Version 1.0.3 is compatible with Blender 4.2 LTS and newer, and is distributed under the GNU General Public License v3.0 or later.

Who is Randomize Noise Offset best for?

Randomize Noise Offset is best for blender animators who use Noise F-Curve modifiers and want to randomize the Offset across many objects at once instead of editing each curve by hand.

How much does Randomize Noise Offset cost?

Randomize Noise Offset is completely free to download and use.

Frequently asked questions

Does Randomize Noise Offset work with Blender 4.2 LTS?

Randomize Noise Offset lists compatibility with Blender 4.2 LTS and newer, and the developer notes the add-on requires Blender 4.0+ with testing done on 4.5. Version 1.0.3 is the current release. If you run one of these supported versions, the add-on installs through Blender's add-on preferences and its panel appears in the Graph Editor. For the exact version you are on, check the developer's GitHub page, since compatibility details can change between releases.

How do I install Randomize Noise Offset?

Randomize Noise Offset installs from a ZIP file. Download the release ZIP, or create one from the addon/randomize_noise_offset folder, then open Blender and go to Edit → Preferences → Add-ons → Install, select the ZIP, and install it. Enable the add-on by checking its box. Once enabled, open the Graph Editor, press N, and go to the Modifiers tab to find the Randomize Noise Offset section. From there you set the Seed and Offset Min/Max values and run it.

What license is Randomize Noise Offset released under?

Randomize Noise Offset is distributed under the GNU General Public License v3.0 or later, which the developer set as the primary license for Blender Extensions. An MIT license is also included in the repository, noted in the LICENSE file. It is listed as free here in the catalog. For current licensing terms and any changes, refer to the developer's GitHub page, where the source code and license files are published.

Does Randomize Noise Offset need any special permissions or external services?

Randomize Noise Offset requires no special permissions. It is self-contained and calls no external services or scripts, so it runs entirely within Blender. The add-on is small, at 2.4 KB, and focuses on a single task: randomizing the Offset of Noise F-Curve modifiers. Because it needs no outside dependencies, installation is limited to loading the ZIP through Blender's add-on preferences and enabling it.
