could somebody please explain falloff (in lights settings as well as in landscape editing) for me? i find it hard to predict with lights and can't see too much difference in landscaping, so what and how exactly does this do? (i guess this is pretty much a language problem i'm having here, so just an explanation of the term should do, i hope), thx

*bump*

falloff determines the softness of the edge of the light before it fades to no light.

for example imagine a hard spotlight on a stage, this would be an example of an extremely high falloff setting.

something like a really soft light bulb that you use in your house would be an example of a low falloff.

ah, thanks.
....
now just somebody please explain the "low"-part to the landscape editing tool as well, doesn't seem to have heard about that...

it's the same thing as with lighting, it controls the harshness of the edge.
