V-Ray 2.0: VRayBPTracer

[anchovy]

Impressive. How many hours took to render this?

I cant give you an exact figure but ive been letting most of the images run the full 65k samples to just see where they can get to so my guess with this one was it was at least 24 hours.

BDPathTracing continued

Here are a few more...


No complaints here.


I let it run till all the sample were used. Reflections of the caustics are the hard part to capture as Vlado has pointed out. I gather another mechanism will need to be used to capture this effect in an un-biased fashion. Perhaps the MTL method from this years Siggraph...


Just not enough samples out there...

thanks for the answer, Michael.
Your 1st image of last post is very nice! (even though it takes 66hr :-O)

Hehe, yeah I just let it run, but im sure I could have killed it sooner. It was looking fine other than a bit of noise in the floor hours before i stopped it.

I love the way the caustics resolve so much faster with the BDPathTracer but as Vlado has pointed out they really don't like to be seen in reflective surfaces or refracted. This one went for quite awhile and I can tell that like the Buddha above the artifacts just aren't going to resolve anytime soon.

Yet a few more...

This is the DBPathtracing version of the scene. Almost enough samples to fully capture the caustic reflections and those seen refracted. No Dispersion here yet like on the PathTracing version.


Heres the pathtracing version with a non vis to cam front wall


Heres the BDPathtracing version that cant have the non vis to cam wall

Another small test, didnt need to run more than an hour or so but I let it run overnight.

I like how the BDPathTracer resolved the caustics on this one.

A quick optical experiment.

11h yup...thats really quick

Ok, poor word choice on my part.

More fun.

Does it works with embree?

[vlado]

Yes, it works fine in my tests.

Best regards,

Aww thats great then the 11h can be down to 7.5 =D
