The Render Preset Manager is a tool that allows users to save and load configuration states for Blender's render and output properties. Users can store settings such as the selected render engine, sample rates, resolution, ambient occlusion, and screen space reflections as distinct profiles. The addon saves these presets as JSON files in a user-defined directory, making it simple to switch quickly between different configurations like low-quality test renders or high-quality final production outputs.

When creating a new preset, users can specify exactly which properties from the render and output tabs should be saved. The addon fully supports both Cycles and EEVEE, with specific compatibility paths for EEVEE Next in modern Blender releases. Existing presets can be loaded, modified, or refreshed directly from the render tab.
