Visual light area


Recommended Posts

I would like to have the below effect



The problem I'm having is that the spotlight doesn't provide me with the total length of the light, so there's no way for me to calculate the measurements for the cone. Can someone please lead me in the right direction on how to get the desired effect?

Thanks in advance.

Thanks for the reply :). I have used light.range but I'm not getting the expected behaviour. Maybe I'm misunderstanding how it's to be used. 

When I set light.range to a certain value, I expect that the light will only travel up to that distance in world coordinates. However, when trying to visualize the cone, the light seems to traverse farther than expected. Here's a sample of what I'm talking about: http://www.babylonjs-playground.com/#VHFLM#4

Note that my math may be a little off, but I would expect the height of the cone to at least reach the sphere which it's not.
