Question by ScienceGuy · Aug 29, 2014 at 01:56 AM · shaderlightingrangecgpoint light

Accessing light's range value within a fragment shader?

In order to compute the proper attenuation of point lights, I need to access the light's range value that is set in the UI. However, I have not been able to find any built-in macro or function that let me do so.

How can I retrieve the range of a point light within my vertex/fragment shader?
