bucket mode unhandled exception.

[super gnu]

im test driving next GPU, and so far i generally like it, although ive not had much success on my current scene with bucket mode. unhandled exception in vray when i tried to render with bucket mode. progressive works fine.

i was reminded (doh) about having decent drivers (i was still on 380)

so i downloaded the recommended 417 driver (417.71 specifically)

now i get an unhandled exception PLUS max crash to desktop..

seems to be related to displacement, as with the displacement modifier disabled, it renders ok.

im not sure if its a memory issue? ive got the displacement turned up as high as it will go before refusing to render in progressive mode.

i was interested to see if bucket mode used less gpu ram than progressive, rather like it does in vray ADV.

im on windows 7, using a pair of maxwell titan X cards, and max 2016

i cant upload a scene here as its a live job and features loads of high res textures.

if somebody at chaos wants it , send me the right email address.

ha. actually since "upgrading" my driver i get an unhandled exception in progressive mode too. great.

same result with 417.35.. for now im going to go back to 380. at least it worked in progressive mode.

not sure why, it seems that with the newer driver maybe i have less gpu ram available? that would explain my maxed out scene not rendering with the newer drivers.. and maybe, contrary to my expectation, maybe bucket mode uses more gpu ram too?

if that is the issue, it would be nice if using too much gpu ram failed more gracefully.. with bucket mode i get a crash to desktop, and in progressive it locks up max and i have to crash it manually.
