I've been playing around with Geometry Nodes and noticed that the "Instance Domain" attribute isn't directly accessible with Octane's shader nodes. Provided are two examples in the form of collections (Linear and Spherical) where they are used in the .blend file below.
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.
Thanks!
