Hi, I'm a developer trying to publish a game. TRYING is the key word here. If I can't bake my lighting, my whole performance gets hammered. I really like Unity but if I can't bake lights into my environment I'll never buy a Pro license. Please fix this issue. Thanks.

Why I can't see this error fix on roadmap????
Lightmapping is the most important part of unity, They must fix anybugs in this part urgently

I hit this problem too. Disabled everything in my scene until it went away and narrowed it down to the trees. Any trees I use, whether I've created them or downloaded them from the asset store, cause some "Clustering" job to just sit there, never completing.

Hitting this as well on 5.3.5f1 :( I had to switch from a Unity Terrain because mobile perf was awful now my 16K mesh that I put in to the replace the Unity Terrain baking is failing at the 5/11 of step. I've let it run for a couple of hours to no avail. I know for certain it's the new terrain replacement mesh causing it. I might be able to get away with realtime lighting but this is a pretty bad bug.

My bakes still fail with one clustering job remaining no mater how often I clear or relocate the cache, open a new scene or even download a new version of Unity..
I hope this issue gets a bit more attention, I can't bake my lighting at the moment :/

Baking in Unity gets stuck on 5/11 when some static objects' scales are too large.

A common example is a default static plane scaled above a certain size. Either reduce its scale or un-check its static box in the inspector. Then it'll work.

Same problem. Baking keeps stuck in 5/11 Clustering 1 job forever... Baking with big meshes doesn't work in Unity 5.

Also having issues with GI

Hi !

I used UE4 for months, the worst public engine ever made with lot of bugs, crashes, and missing usable C++ interface for programmers.

Unity is better, and more stable, but don't fall into the trap UE4 does. At a certain engine code & feature complexity there should be less new features & refactor, than BUG FIX.

100 - 200 people voted to fix this bug, but 10000 - 20000 people want other bug fix?
So you guys fix the 10000 - 20000 voted bug?

What if 100 - 200 people are real developers with very big sale & money potential, bigger than 10000 - 20000 people?

If this isn't true, then I say nothing. But tell me which product's team want to tweak the lightmap and their settings?. A prototype project with some placeholders in the beginning stadium, or the other, think about it. Thanks.

The fact that lightmapping is basically broken in Unity is ridiculous. We have a pretty large arch previs scene that crashes every time we try to bake. We keep dropping the baked resolution to no avail. To describe this as a catastrophe would be an understatement.
