Lightmap problem, how to solve hard shadow?

[Bin4ry]

Like image below, how do I solve the hard shadow? (Of course I'm looking for a natural one)

Is hard to try each setting and apply lightmap cause it took a lot of time.

Currently light setup:

Sunlight, at far top with 127 Intensity, 20000 Range, 127 Increment, 0.001 Falloff and cast shadows ON.

Ambient, as shown in the picture, has same setting as Sunlight.

You must never enable 'cast shadow' for both lights.

Try this:

Name: Sun
Position: -1000, 10000, -1000
color: 0, 0, 0
Intensity: 100
Range: 200000
Max. Light Inc: 256
Light Falloff: 0
Cast Shadows: Empty

Name: Ambiance
Position: Doesn't really matter. Just place it somewhere in the middle of the map, and pull the lightbulb up for a good bit.
Color: 0, 0, 0
Intensity: 156
Range: 200000
Max. Light Inc: 256
Light Falloff: 0
Cast Shadows: Checked

It's been awhile since I've done mapping, but if I remember correctly that should set a proper day light.

Good luck.
