We recently upgraded our project to Unity 5.5.0b5 for the iOS web request POST fix. However we later discovered that all our lightmaps now render with this harsh color banding. Attached are images showing how it looks in 5.4.0f3 (our project's previous version) and then in 5.5.0b5. We've tried clearing the GI cache, updating to newer beta versions up through 5.5.0b7. The lightmaps aren't being compressed, so that's not it either. Has anyone else had any issues with lightmaps in the 5.5.0 beta releases? At this point we may need to attempt a conversion to 5.4.2 when it's put back up in order to address the POST fix and the lighting issue.
