Beast Help

Hello,

When i bake a light map on my terrain, it just doesnt look exactly same as realtime shadows. Can anyone help me setup beast to be same as realtime shadows please.

One more question, when i use lightmaps, trees on terrain get dark and not get affected by ambient occlusion or any other thing, but on the other hand when they are bilboarded, they look very light and it looks terrible this way.

Can anyone atleast tell how lightmap size and resolution look like if i have a terrain with 500 units width/height and 512px heightmap?

I did lightmap with 2048px with 100 resolution and still looking terrible!!
