Any chance to see Bi-directional path-tracing in mr?

[Carno]

I would like to ask if there is any chance mr implements bi-directional path tracing, or progressive path_tracing ?

(I am not sure if this could be done with shaders like with the path mat , or if it would require to have the core code of mr rewritten)

I think it would be really useful if it can be implemented. :)

Cheers

Because mental ray is a framework, most rendering techniques can be implemented with the right shaders. Think of shaders as plugins.

That said, I don't know specifically of a bidirectional, or progressive, path tracing set of shaders available currently. There is a regular path material in the physics shader lib, with the source freely available to look at. And I may very easily be missing one available out there that I don't know about yet.

What is your goal? And what is your timeframe?
