I've found this ISF shader, an underWater volumetric lights, it works ok on ifs.video, but when I try to use it in Millumin nothing happens. And there's no error message. I don't understand.
Indeed, the variable "Caustic" is never initialized. So maybe it works with WebGL (in your browser I mean, because it is more permissive) but the behavior may be erratic in general, with OpenGL for example (in an application I mean).
In brief, rewrite the code as follow : float Caustic = 0.;

Hi, a second related question :

Hello @hyll,
This is normal : there is a mistake in the code.
Indeed, the variable "Caustic" is never initialized. So maybe it works with WebGL (in your browser I mean, because it is more permissive) but the behavior may be erratic in general, with OpenGL for example (in an application I mean).

Thanks a lot Philippe !
And by the way, I found out where was the caustics shader I was thinking about : in Madmapper ;)
