If you use the vmanip mapgen object in an on_generated function, you can run set_lighting and calc_lighting functions to e.g. add shadows to floating islands in singlenode mapgen.
l think instead of making calc_lighting directly calculate the light it could remember that the mapchunk needs light calculation and then the light becomes calculated only one time after the on_generateds are executed.

Re: calculate lighting only one time
This can already be done with 'mg_flags = nolight', then lighting is not calculated after core mapgen but is done only once after 'on generated' by a mod's LVM 'calc_lighting' call.

What would happen if two mods register 'on generated' and both do a 'calc_lighting' call?
