weird streak when rendering with rtx but not with cuda or cpu with vray 6

[nicolas_ierino]

for some reason when I render using rtx at certain angles I get a very strange streaking effect only with vray 6 and it only seems to happen with geometry that used to be in vray 5, I tried copying and pasting the objects into new files and isolating the problem objects using maritiral override but I still get the strange render, however when I tried rendering with cuda and cpu and with rtx interactive render this doesn't happen and when I redaw the objects it it seems to be fixed which is ok for simple geometry, im just worried I wont be able to render any of my previous files

Dear nicolas_ierino, hello.

Excuse us for the delayed response!
You have limited the behavior to Production rendering on RTX, which is a good report.
But to check all possibilities why this is appearing, could you please share one of this sample scenes (where the geometry is pasted) via our contact form by using V-Ray > Pack Project?
Are the units of the old and the new blank scenes the same

Please share also the exact type of your Graphics card and the current driver version.

Thanks in advance.
