Lightmap Baking taking too long around 4-5 hours.

Hey, Whenever I am trying to bake my lightmap, it is taking at least 4-5 hours. I am attaching my Lighting Inspector, I have around 10-15 point lights. Any help or suggestions?? Is this normal? Even when I have baked the lightmap and I make some minor changes to the scene. It's still taking 4-5 hours to bake the lights again.
Thanks

 

4-5 hours is not that bad. Reduce resolution from 40 to something like 10.

 

4-5 hours sounds like a very long time.

I can bake 10-15 scenes in that time.

A few things that will speed up you bake times significantly.

1. Get your lightmaps as small as possible while still maintaining the look you are going for. This will get them to fit on less textures, and speed it up.

2. Eliminate meshes from your bake that no one will every see.

2. if a mesh is in either all light or all shadow, reduce the lightmap scale for that mesh.

Doing those things will help speed things up and you can have better quality light maps since you put the texels to work where they have the greatest impact.
