Thanks for the tip! That does indeed seem to be *exactly *what I am looking for. However, I cannot quite seem to figure out how to actually generate the map on my existing map. I managed to get something going on a new map, but it’s quite inaccurate and blurry, but I suppose I can adjust the settings.
My world uses dynamic lighting only, but I tried to temporarily bring in a static light so that I could build lighting and hopefully generate AO maps. But I appear to be stuck with the temporary “preview” lighting only and it will not build anything even if I build lighting.
