Area light baking broken, continuous baking slow

Unity Engine
1

I’m using Unity 5 B16.

I have an area light in the scene, and a bridge. The lightmapping will get stuck everytime when there’s an area light in the scene.

Also, continuous baking is very very laggy when using large terrains. I have a terrain that’s 3000x3000, 2048 resolution. Whenever I do a change that affects the terrain visually, like an emissive sphere above the terrain, it has to rebake the entire terrain (isn’t it supposed to be pieced into chunks?) and takes a couple minutes. During that time the editor is too slow to do anything with. I also have a very fast computer. Yes, I can turn continuous baking off… but the feature would be really excellent if I could use it with less issues.

Hi! Please file a bug report with the area light + bridge scene. Thanks!

Even when moving one object, we currently have to recalculate for the entire terrain. For 5.X we will experiment with a voxel based approach, which should make it possible for us only update the parts of the scene that actually changed.
