Lighting Bugs

OK, lighting is borked for creating new levels. Lets get some conversation going that doesn't get buried under endless posts about making characters bi and taking their clothes off :p I'll start by listing the bugs we have found so far.

1. The lightmap 'cracks' along chunk boundaries in terrain levels, producing unexplained shadows.
2. Sunlight doesn't work in terrain levels. An ambient light must be added
3. Water is broken in game. Looks fine in editor, but non-existent in game.

Reproduction Steps: All steps assume starting with a clean terrain level built with these options:

And all have the following basic steps:

1. Save the level
2. Add export area
3. Define area - set the green square to cover the entire mesh
4. Add a start point roughly in the center - Possible bug? If I add the start point before the area, path finding will not recognize it.
5. Set start point in export area
6. Click Render Lightmaps
7. Toggle Lightmap on and Fully Lit off to verify there is no light. This confirms bug 2, no sunlight. Unless I've missed where it says sunlight doesn't act like, well, sunlight.
8. Add a light roughly in center. Change type to Ambient, Postion.Z to 25
9. Toggle Lightmap off
10. Hit the Render Lightmap button
11. Toggle Lightmap back on to verify ambient is working. I have never seen lightmap cracking at this point.

Phew. And I don't really want to admit how many times I've gone through this.

OK, working on getting the reproduction steps down exactly. Will continue editing in 20-30 minutes.
