My team and I have been working on some tour visuals for the past month with some pretty crazy Houdini sims and now we're trying to render out the 7,000 frame sequence and in order to do so we're using Vray + Houdini on AWS using Deadline's AWS Portal system.
It took us about a week to get to where we are now but our render times on a g3.8xlarge are still over an hour and a half, with 75%+ of that time spent with nothing happening. In the Vray logs, I can see that while rendering this frame it spent 40 minutes doing nothing:
2019-10-10 04:55:02: 0: STDOUT: VFH [Progress] V-Ray: Prefiltering light cache... 100%
2019-10-10 05:37:09: 0: STDOUT: VFH [Info] V-Ray: Average rays per light cache sample: 7.51 (min 1, max 398 )
On top of that, I'd love to be able to take advantage of hybrid rendering since we have 32 cores sitting there (and billing us per core hour), but the issue is that Vray says C++ CUDA implementation needs to be "set explicitly" to use the processor but we don't have matching machines in our office that we can submit with in order to have that checkbox checked off.
I'm under a lot of pressure to get this done (we're already a week late due to rendering issues), and would appreciate any help I can get!
Attached is a full render log for one frame where you can see the big slowdown.
Thanks in advance.
