My understanding is that Dual Scattering gives you similar results to
Marschner with full path tracing, just that it's a faster
approximation? It's been a while since I read this paper though.
Anyway, the fact that it's an approximation is no problem, it's a very
good one and in used in production by e.g. Disney. So I'm confident
this would be a great feature to have.

Ah, if this is your research area then it's a great fit of course!
Definitely no need to pick another topic then.
Thanks,
Brecht.
