GN Rolling Shutter fills a narrow gap the developer hit firsthand: an architectural render that called for metal curtains with no procedural option available. Keeping the setup parametric, it turns a selected mesh into a shutter you tune through width, height, slats and color settings.
GN Rolling Shutter is a parametric add-on for Blender that generates procedural metal curtains, also called roller shutters, inside a scene. The developer built it while working on an architectural render that needed metal curtains, having found no procedural option for the job.
To use it, install the add-on through Edit > Preferences > Install from disk and enable its checkbox. The tool then appears in the N panel of the 3D viewport. Select a mesh object, click the GN Rolling Shutter button, and adjust the parameters. It works only with mesh type objects. Available settings include width, height, door opening, padlocks, slat type and colors.
Results are set up to render in both Eevee and Cycles. This is version 1.1, released under the GPL license and marked as Blender extension compatible for versions 4.3 through 5.0. A demo video is available.
Gn Rolling Shutter is best for blender users who need procedural metal curtains or roller shutters in a scene, such as the architectural renders it was built for.
Gn Rolling Shutter is completely free to download and use.
GN Rolling Shutter lists compatibility with Blender versions 4.3 through 5.0 and is marked as Blender extension compatible. It's distributed as an add-on, and its render output is set up for both Eevee and Cycles. If you're running a version inside that range, the add-on should install and appear as described. For anything outside 4.3 to 5.0, check the developer's page before installing, since support there isn't stated in the listing.
GN Rolling Shutter installs like a standard Blender add-on. Open Edit > Preferences, choose Install from disk, and point it at the downloaded file. Once installed, make sure the add-on's checkbox is enabled so it activates. You'll then find it in the N panel of the 3D viewport. Select a mesh object, click the GN Rolling Shutter button, and the parameters become available for adjustment. The developer's page includes documentation if you need the full walkthrough.
GN Rolling Shutter works only with mesh type objects. To use it, select a mesh in the 3D viewport, open the N panel, and click the GN Rolling Shutter button. From there you can adjust parameters such as width, height, door opening, padlocks, slat type and colors. Because it's tied to mesh objects, other object types won't trigger the add-on. Start from a mesh and the parametric setup takes over from there.
GN Rolling Shutter produces results ready to render in both Eevee and Cycles, so either engine works for the shutter. The setup is parametric, meaning the roller shutter adapts as you change its parameters, and colors are among the adjustable options alongside width, height, door opening and slat type. This suits scenes like architectural renders, the context the developer built it for. A demo video is available on the developer's page.
GN Rolling Shutter is listed as free in this catalog. Licensing details can change, so check the developer's page for the current terms before you download. The add-on is released under the GPL license and is marked as Blender extension compatible. If you have questions about usage rights or redistribution, the developer's page is the best place to confirm, since GPL terms and any listing specifics take priority over a catalog summary.
