Scene Lightmap Checker for Unity
- Digital500 JPY
Make your lighting workflow easier, faster, and more reliable!
What it does
This Unity Editor tool scans all FBX meshes in your scene that contribute to Global Illumination and categorizes them based on their UV setup: Automatically Lightmapped Models set to generate secondary UVs for lightmapping. Manually Lightmapped (UV0 + UV1) Models with both primary and secondary UVs properly configured. Not Lightmapped (UV0 only) Models missing secondary UVs, which can cause lighting issues.
Key Features
Quickly locate problematic models in your project and jump straight to their assets. Toggle automatic lightmap UV generation on/off with confirmation dialogs. Auto-generate missing secondary UVs for meshes that need them, saving time and avoiding lighting artifacts. Clean, organized UI designed for a smooth workflow.
Who is this for?
Artists, level designers, and developers who want to keep their lighting clean and optimized by ensuring all FBX models have proper lightmap UVs — without wasting time hunting down issues manually.
Changelog
### v1.1.0 ## Added * Implemented user preferences for display type. select to highlight them by GameObject or by mesh! * Sticky action buttons (Disable Auto Lightmap UVs and Auto Generate UV1s for Missing) relocated above the footer bar with a sticky bottom layout for better accessibility and consistent UI experience. * Resizable scroll area for expanded model lists to handle long content without being cut off. * Scroll view height is now calculated dynamically based on window height minus the footer area, preventing content from overlapping with sticky UI elements. ## Changed * Footer and sticky button zones visually separated and fixed in place to maintain usability regardless of scroll position. * Buttons and controls receive consistent spacing and alignment to avoid pixel offset issues. ## Fixed * Scroll content no longer renders behind footer or action button bar. * Corrected vertical alignment offset for rescan button and settings icon for cleaner interface. ## Improvements * Refined DrawSection foldouts with scroll support to allow navigation of large datasets in the lightmap checker. * Better window size handling, making the tool more resilient to resizing and longer lists. ### v1.0.0 ## Initial release
