Not at the moment AFAIK - ORC is independent of the host app, just like standalone.
That being said, anything that correctly bakes to ORBX file right now and plays back in standalone should also render the same on ORC. In theory procedural volumes from the DCC app would bake to an animated VDB in the ORBX export process or the ORC snapshot upload.
We are looking into expanding ORBX nodes in upcoming releases with portable C modules that could be used to drive procedural volumes and geometry in the ORBX node graph without baking data to a file - some of this can already be done entirely in lua script nodes, but this would provide native performance and direct C API access to the renderer. In tandem to these modules, we are also introducing native bone/skin animation (eg. FBX/glTF) in ORBX w/ Octane 3.07 as well as OSL procedural textures/materials/shaders in 3.10.
You can see WIP of this in the GTC17 slides:
