Like the title says, we have to do a lot of renders of a lightweight scenes that are only a few seconds per frame. Having deadline start multiple V-Ray RTX sessions on the same machine speeds things up considerably and I just want to confirm this is actually a "supported feature" as long as the hardware can handle it oc.

Hello!
Starting multiple instances of Vray standalone for GPU rendering is totally fine, specially for animation rendering. In my case I have 4 GPUs in my machine, the workflow is to render one frame per GPU simultaneously so 4 frames on 4 GPUs
And using progressive mode with maximum of 1 minute per frame(if you have beafy GPUs), this is very efficient in case of multiple GPUs it will be faster than having all GPUs work on the same frame
Best,

Ok thanks for the insight! The thing is we only have a single 3090 in this machine on which multiple instances of V-Ray are running and sometimes an instance "forgets" all it's assets like a cache is flushed without it being aware of it and it just continues to render ut empty frames without any warning.. So my first thought was that the instances are getting in each others way somehow. This might be less likely if they all run on their own card like in your setup.Last edited by jonathandeblok; 14-07-2021, 02:53 AM.Comment

Did you monitor your VRAM on this? specially at the start, when it loads textures and geometry into VRAM. Does this happen in every scene?Originally posted by jonathandeblok View Post
Best is to have multiple cards with this setup, doesn't need to be 3090s.. 3060s are great value as well

Yeah ram usage etc is all fine. Last night we ran a batch with a single V-Ray instance and we still get white frames now and then. Wrote a small script that check frame filesizes and resubmits those that are under a certain limit to somewhat work around it but it's not pretty
