Lightmap equal to the the realtime shadow

Hi guys, i’m relatively new at unity, and i ran into a problem with shadows. My problem is that i have 8 lights that have to cast shadows, but that obviously takes a lot of processing power. All the objects on the scene are static. My thought is, unity have to reprocess all the real-time shadows because the objects can move, but at my scene they don’t, why can’t i make the unity process the shadows once. I saw that there is the lightmap option, but the lightmap never looks like the realtime shadows. If someone understood my problem, please help.

Ps:Sorry about my English.

the lightmap is usualy darker. the shadows never look the same, sometimes they are pixelized, sometimes they don’t exist. i read about lightmapping, saw some tutorials, and all i saw was people trying to make scene look more beautiful, with global illumination and … but thats not what i want, i just want to change the real-time shadows for baked shadows without changing the scene.

Try playing with the settings. And please, don’t post comments as answers.
