here it is working code..so, all you need is to after your lightmaped level is loaded, call function >Lightmap_Array(lightmap)< before main loop, and in main loop do just this >ShadeEntity(entity,ambient=90)< and you are set..I hope this helps..
Dim LightmapArray(0,0)

Global LMArray_height#

If RD# > 255 Then RD = 255
