OpenScatter is a free and open-source Blender add-on designed for non-destructive, artist-friendly scattering of objects (e.g., vegetation, rocks) with advanced controls, optimization features, and dynamic animation tools.

Yes! OpenScatter is licensed under the GNU GPLv3, meaning it’s free to use, modify, and distribute. You can download it for free on GitHub. Purchasing on BlenderMarket is optional but supports the project and the Blender Development Fund.

The supported Blender versions are 4.2 LTS and above. I plan on providing support for all future Blender versions.

Scatter systems are the core of OpenScatter. You can think of each scatter system as its own layer. For example, you can have one layer (scatter system) for grass, one for rocks, and one for clover. This allows you to keep everything organized and non-destructive.

An emitter object stores all the info and settings for your scatter systems. When you use the addon, you pick an emitter object, then you add and adjust scatter systems for that emitter object. To add scatter systems to another emitter, just use the object picker at the top of the panel to select a new emitter object. All scatter systems will be stored and linked to the appropriate emitter objects.

Yes! You can use OpenScatter for just about anything you want. However, if you work on a team and/or on larger commercial projects, donating would be super appreciated <3

Yes. The GNU General Public License v3.0 allows you to redistribute/share and modify the addon—provided derivatives remain GPLv3.

Yes. As long as you follow these key rules (and follow the official license):

1. You Must Give Recipients the Same Rights: When selling, you must provide the full source code of the GPLv3 software to buyers. Buyers must also have the freedom to share, modify, or resell the software themselves. You can’t stop them.

2. No Extra Restrictions: You can’t add terms like “You can’t redistribute this for free.” The buyer’s rights under GPLv3 stay intact.

You can report any issues you're having with OpenScatter on the issues page of the GitHub repository.

The best way you support the development of OpenScatter is to purchase the $10 version of the addon on BlenderMarket. You can also support via Kofi or Liberapay.
