Cloud Build Lightmap Baking


  • My build in Cloud Build is much darker than a local build.
  • 3D assets are dark when using Cloud Build to build the game.


Unity Cloud Build does not currently support building light maps. There are a couple of possible causes which might explain what is going wrong:

  • You are using Precomputed Realtime GI for your scene and the Auto Build for lightmaps is enabled. 
  • Your build results are not checked into your repository. 


Make sure that you have turned off Auto Build in your scenes (it is a per-scene setting), and manually build (and commit) your light maps. Depending on what your scene includes, you will need to commit the following files:

  • LightingData.asset
  • LightmapSnapshot.asset
  • Lightmap-xxx.exr
  • Lightprobe-xxx.exr

The files are stored in a subfolder named after the scene in the same folder as your scene. For more information about lightmaps please read here
