Is there a way to control the fall off of an emission shader? Maybe by using the flightpath, ray length?
I’ve tried but what I actually need is a way to stop the lighting after a specific distance. I tried with path length but I can’t make it work.
Maybe i’m totally wrong but isn’t the ray length made for this ??
Playing with a simple spot light (very sharp of course… float curve was an other idea but less than is better for presentational purposes)
and as well with an emmisssion shader on a simple plane…
Playing with the threshold (or any better fitted float curve ) may be enough?

Yep! That works! Tried it with the plane and it’s all good! Thanks!
