We upgraded to 5.2.0f1 to try some of the new VR optimizations, but we've been unable to bake lightmaps without our dev machines running out of memory. Unity goes from about 4 GB of memory used to 14 GB over the span of a few seconds when it begins the "atlasing" stage of baking. The project we're trying this with bakes in 4.6.7 without any trouble, and takes a long time in 5.1f3 with the same settings we're using in 5.2 but finishes OK. Scene is about 100M wide and 500M long, but it runs at framerate on Gear VR and shouldn't be very complex from a rendering standpoint. It's the first time we've ever had memory issues with the editor. Uninstalling all Unity versions / reinstalling did not seem to help. I can't attach a sample project easily to submit a bug, so I'm wondering if anyone else has encountered this issue or if there are steps I can take to clear caches or other bad data that may be causing it?
