Light falloff?

Unity Engine

Is there a way to control the falloff of a light?

I’d like to have a bright point light with a hard edge (e.g. up to “range” the light is full bright, after “range” the light is zero). The combo of range and intensity isn’t giving a hard edge.

Any ideas how to achieve this? I thought about trying to use geometry with additive blending, but I need the light to work and cast shadows correctly.

Thanks

What is the purpose of the light? Wouldn’t a spot work better for this?
