Is it possible to enable pathtraced (brute force) caustics in Karma? Ala the old Mantra “All paths” ray filter? I don't see a value on the geometry or render settings prims for enabling all paths.

If not net implemented, will it be so? Seems worth it to add even if the results are not usually able to converge in a reasonable amount of time.

It would actually be really nice if a VCM-style integrator to sample Specular->Diffuse->Specular paths (like Renderman currently does) was on the horizon for Karma, since it handles these types of scenarios very efficiently.
