In the screenshots, my intent is to have the instances turn white when they are to one side of the Empty, and the rest to be black. Notice how Octane doesn't produce the same output as in EEVEE.
I found adding a "Realize Instances" node to the end of the chain will produce a similar output when using Octane but that would not be feasible when working with a large number of (and more complex) instances.
