Ok, this algorithm is probably the best thing you can get to render reflections/refractions of caustics (objects enclosed in glass, water caustics, …) in an unbiased way
excuse me while I do my victory dance
Great! Thank you!
Oppa OH YEAH STYLE ! 
waited for it !
Sweet !!! Just brilliant
That’s just Amazing!
wow!! really its going to help alot with scenes that require light plus glass and reflections on metals, i´ve never heard of vcm but it is more accurate than metropolis i see it on the link posted. this will come with the new alpha corona version? this release will come in christmas or before christmas? thanks for the hard work to make this posible in cg.
Well done. Can’t wait to try the new alpha/beta.
Thank you!
it look very helpfull, i have often problem with noise in reflections like this in vray.
Faster for caustics only means it can replace PT in term of speed right ?
Perhaps an option to turn off caustics with PT and render caustics only on a different pass with VCM ?
This fix will be released in the next alpha or it is available in dropbox ?
because i did test the latest legacy ( 27 nov ) and i did test VCM mode but it gives me weird result.
some basic version will be available hopefully soon
Thank you for being awesome!
I tried reproduce scene and render it in maxwell, here is result, rendertime 50s :
In summary is noise litle bit more reduce in maxwell but in reflections (most critical areas) is very similar. if you use unbiase setup of course.
Good job
I would like to try more complex scene
Edit: now i notice that in maxwell version is coplete missing some reflection …weird
Yes, it is missing exactly the problematic part 
i think since version 2 there are some optimalisation, user can change shading quality on each object, default is low. i guess it is therefore.
This whole technique stuff is pretty amazing, I didn’t understand what bidir really does and why it isn’t as fast as pt but solves some problems - (excluding this one here). But I found a page for everyone who’s interested to learn the principles:
http://youtu.be/QhJhVkbCgVU hundreds of videos explaining render stuff
Now I got it
Will Bdir and VCM ever be able to work with HDcache to speed up things ?
no, there is no framework yet to use caching for bidirectional methods
Great find, I will be watching them.
