Render Manager is an addon for Blender built around batch rendering across multiple cameras. Rather than starting each render manually and waiting for one to finish before the next, you select any number of cameras and let the addon render images or animations from each of them automatically in series.
The addon also lets you save all your render settings to a file and load them whenever you want. This makes it possible to build your own library of render presets to reuse across future projects. It works with both Eevee and Cycles settings, so presets can be saved and applied for either engine.
JSoftWorks positions the tool for situations that call for multiple cameras, such as ArchViz and product presentations, where rendering from each camera in turn is necessary. The addon ships with documentation, and a short video tutorial is available for reference.
