Area Lit with Volume Lighting My understanding is that if a light is brighter, it will light a larger area. (Like a point light.) If I try this with a volume light, it seems to only light an area proportional with its scale, not its brightness.

Here is an example:

Emission set to 10:



Emission set to 100:



Emission set to 1000:



The .blend I used to test this is here.

Is there a way to light a larger area without changing the scale of the volume?
The light does travel farther, its just that volume lights take longer to resolve. If you up your samples you should see the light extend further. You could also use a standard emission shader without volume which will render faster.
