<div class="moz-cite-prefix">Okay, are you trying to tell me how to
implement it in blender's code or something? Because I was just
asking if it was possible. I won't be able to implement it
myself, as my current knowledge of C++ is only sufficient to make
minor tweaks.<br>

<div dir="ltr">I know what do you mean, you want a sampling for
caustics only, let's see how caustics are created:<br>
ray emit from the camera, hit a diffuse surface, bounce to a
glossy/refraction surface (with low roughness), hit the light.<br>
so to get a better caustics you will need to increase diffuse
samples.<br>
<br>
but on the material side, you can catch indirect caustics, but
using is singular ray and is glossy/refraction rays for low
roughness shaders.<br>
<br>
to catch direct caustics, you will need first bounce to be "is
diffuse ray?" when your actual shader is a glossy/refraction
material.<br>
to reduce caustic noise you will need to increase roughness of
your glossy/refraction shader after the diffuse ray. (this will
allow to catch more light paths).<br>
hope I didn't mess anything, if I mentioned anything wrong
others may correct, thanks.</div>
