If you create a Noise4D node in C4D Octane, attach it to a material, and put it in the LocalDB, you can load that material back into C4D Octane and it works. You can also load it into Standalone and it works (as a "Cinema 4D Noise" type node there).
If you download that material to Standalone, edit it, and post it back to the LocalDB (or LiveDB), when you open it again in C4D Octane, that node is missing.
If you create a new material in Standalone, add a Cinema 4D Noise to it, save it in the LocalDB/LiveDB, and open it in C4D Octane, the Cinema 4D Noise node is missing.
It doesn't appear that you can post materials from C4D Octane to the LiveDB, so this could be an issue if you have to go through Standalone to post it and want to use that material in C4D.
