Sorry my English.
If i use vraydirt whitout GI - vray ignore antialiasing samples.
Example - add chanel vraydiffusefilter and see it. I use adaptive QMC +1+4. vraydiffusefilter chanel - very draft and noise. If i use GI and adaptive QMC 1+4 render pure.
If i not use GI render - pure only if AA +4+4…its a very big bag 
ya budu pisat po russki.
Delo v tom shto vray shtobi pravelno zdelat antialiasing nado iznachalno proshitat te mesta gde illumination est i gde net, shtobi provesti adaptation samplov. Esli u tebya vikluchen gi, to scena ne osveshaetsa i v teh mestah gde chernoe budet malo samplov. Stavya sampling na 4/4 ti prosto povishaesh minimum samples per pixel. Tozhe samoe mozhno dobitsa esli postavit ochen malenkiy theshold.
Mozhesh poprobivat otrenderit bez gi, no postav antialiasing adaptive qmc 1/64 i postav threshold na 0.005
Ditto, Morbid 
Raise max, not min, and lower nose threshold.
Lele
Privet Morbid Angel 
Kak eto priyatno pisat na russkom
spasibo chto prinal uchastie v obsuzhdenii problemi.
mne kazhetsya tii ne ulovil sut ocherrednogo baga vray
1. dobav kanal vraydiffusefilter
2. otrenderi bez GI i s adaptive QMC +1+4 treshhold 0.002
3. teper vkluchi GI i otrenderi s temi ge nastroikami
vidish raznicu? vray prosto krivo rabotaet s antialiasingom i delo ne v treshholdach u menya oni silno kachestvennee chem 0,005
pri tech ge usloviyach ambient ocluzion v mental ray rabotaet korrektno
sorry i can’t resist :
haaa… ca fait du bien de pouvoir parler de Vray dans sa langue maternelle…
effectivement, je pense qu il y en a marre de tous ses forums en anglais… je n’en peux plus…
mais bon si tout le monde commence à faire ca… ca riSque d etre un gros bordel. Et on ne pourra plus se partager nos informations.
alors bon, le réponses en goulatch , c’est pas génial…
moi je vous laisse entre vous…
salut les filles… a+
sorry… :lol: :lol: :lol:
sorry i can’t resist PART2 /
Very funny …
sorry…
A ti mozhesh zdelat sample scene?
he started the thread in engrish, why can’t it continue in engrish?
Suis bien daccord, la misère si on se met à parler dans notre belle languasse.
AU fait j’en profite: je ne savais pas que tu étais français man(au zut de l’anglais, faut dire qu’avec ces forum c’est dur de parler autrement eheheh)!
enfin bref, moi aussi je vous laisse entre vous.
D’ailleur, je connais quelques russes qui gardent pas mal de trucs pour eux notamment un certain script très convoité :roll: :roll: :roll: :roll:
Bon allez, j’en profite aussi pour dire que ce forum est le meilleur que j’ai pu voir, trop bon esprit/ambiance etc…
allez ciao banbino!!!
yes…now that we all layed out our thoughts…I will finish this by saying that the issue has been resolved
thanks for participating :)))
how was it resolved?
Just incase anyone with a similar problem or mistake can find this thread usefull 
well, his understanding of sampling was not quite what vray was doing. If you have a well lit scene, eather with gi, or with lights, you will get proper antialiasing. If you have everything turned off, then resulting RGB buffer will be black, vray will determine that the color value of each pixel is 0.0 and apply minimum specified samples to it, hance producing badly antialiased buffers.
The best way to understand this, is to take a sphere and shine a directional light onto it from a side, and output something like a normal pass, you will see that where the sphere is black, there is much worse anatialising, then where there is illumination.
