I have two computers on my network: Main system is:

Windows 10 Pro workstation: CPU 3990x: GPU Titan RTX: This is the local computer

Windows 10 Pro: CPU Dual Xeon E5 2660v3: GPU Radeon Pro Duo Polaris: This is a render node

I have all the settings set up for the render node: CPU+GPU but the render node is only using the CPUs. GPUs are idle. The GPUs on the render node, render the scene fine when not using crowdrender. How can I get this working properly?
