Qol Tools: Ringarray creates circular arrays from any source object, light or camera in Blender. Rather than manually copying objects, setting the pivot and working out the angle math, or stacking a linear array modifier with a curve modifier, the add-on builds an array with a single click. The result is linked duplicates rather than bent objects. It's available in the Blender 4.2 Extension format.
The interface is divided into three sections. The main section is where you enter values, and it remembers those settings for future arrays in the current Blender session. The tweak section covers the translational adjustments available to the current options. The options section lets you set arrays up in your preferred workflow, whether that's linked object arrays or single mesh output.
Those options can also be set in the add-on preferences so they carry over between sessions. Ringarray is released under the GPL license and supports Blender versions from 3.0 through 4.2. A demo video is available on the developer's page.
