Every time I "open viewport" using the octane render tab in Rhino, the window opens but only shows a portion of the screen area, the rest is black. Under "film settings", I select "rhino window" for resolution, but this doesnt seem to do anything to fix the problem. Black are persists. There is the "region size" option, but then I have to manually slide the slider and guess the size of my rhino window. Is there some way to tell Octane to automatically show me the full RHino window in the render viewport? Thanks. see attached screenshot.
