AutoLightmapUEr v1.3 +)

 AutoLightmapUEr v1.3 is an Unreal Engine editor plugin that automatically assigns lightmap sizes to all static mesh actors (or actors with static mesh components) based on a selected preset defining the desired sizes and resolutions. It ensures consistent lightmap density across the level, reducing lighting build times and saving memory. The tool analyzes each mesh's world size and adjusts its lightmap resolution according to the preset values you define. Users can create custom presets tailored to specific projects, enabling precise control over lightmap settings. Benefits include reduced lighting build times with minimal visual impact, consistent static shadow sharpness across all props, and significant memory and file size savings—especially beneficial for mobile game development.
