It is in the DE-Raytracer (which is the default raytracer for most exemples).
It is not (yet?) in the Soft-Raytracer (not included in the release, you have to compile the git version for that)

The last blueish pic here, with DOF effect, use the Soft-Raytracer. The others use DE-Raytracer.

This one of the nice thing of fragmentarium, the raytracers (raymarcher :embarrass: ) are in glsl too so you can modify them on the fly to fit your purpose :)

Code:

			if (Reflection>0.0 && (hit != vec3(.0))) {
				vec3 d; vec3 d2 = vec3(0.0);
				// todo: minDist = modifiedEps?
				vec3 r = normalize(nDir - 2.0 * dot(hitNormal, nDir) * hitNormal);
	
				vec3 c2 = trace(hit+4.0*r*minDist,r,d,d2);
				color += c+c2*Reflection;
			} else {
				color += c;
			}
