Instead of scripting it using seteffect, you can change the colors of the tilelayer itself to have the same effect... but I don't like the look of just the tiles being colored, but all sprites/NPCs not. This includes doors and such as well. If we had more image layers we could use a polygon with mode 0 to have a much better looking effects, but ya...

The lighting themselves could be very smooth if done right. All it needs is a buffer calculation between the hours that will smooth for each minute/second or so. It's not that hard and I've done it plenty of times before.
