Way to do a quick and dirty bake?

I have a scene with about three dozen light, most of which are area lights. This causes my bake time to be in the hours. Is there an easy way to do super low quality bake without having to change all of my light settings just so I can see what I'm working on without doing a full bake?

 

Progressive or Enlighten?

 

Progressive.

 

Lower your bakeResolution (e.g. to 5 or 10), that will reduce the space each object occupies in the lightmap, so the scene will need fewer rays to be computed.
The downside is that lighting is going to look blurry, pixelated and you may lose small details. But for the general feel of the scene colors that works fine.

If you need more details in some objects, you can keep your bakeResolution low so that the bake gets faster, but for those meshes you need to see in full detail, make the ScaleInLightmap be 3 o 4.
