Unable to get VRAY RT to work via DR

[alester]

I am trying to use VRAY RT distributed rendering, but on the second machine keep getting "error: Cannot initialize CUDA! No CUDA devices are available!"

The machine in question has two graphics cards a Intel HD Graphics 400 & a NVIDIA GeForce GTX TITAN.

I am using VRAY 3.4 on both machines as well as Max 2017.

Does anyone have any advice on how I might be able to either fix this problem or at least determin which graphics card the RT server is trying to use.

Any help would be appreciated.

Have you tried updating the drivers on the second machine?

Great thanks, that worked. Being an older machine the drivers have clearly not been kept up to date!!

Ok then, glad that it's sorted out
