OpenVDB not working with GTX Titan Black Tweet

[hdace]

Hi, I've been using my PC with a couple of RTX 3080s to render scenes using Octane OpenVDB and it's been going fine. LW Octane plugin version is 2020.2.5.1

I would now like to use my older Mac with two GTX Titan Blacks to render similar scenes with Octane OpenVDB but the volumes aren't rendering. MacOS is 10.13.6 and I'm using NVIDIA Web Driver (not native OS driver) 378.10.10.25.106.

Is my problem a hardware limitation or does one of the software elements need to be updated?

Thanks!

Forgot to mention the CUDA driver is 418.163. I'm assuming this is the culprit. Nvidia have not updated Mac CUDA for a long time so maybe this old machine just can't do Octane OpenVDB. I know it's not the hardware now because I tested an old PC with a Titan Black in there and it rendered the volumes fine.
