So, just wondering, and I don't know how all of this works, but, since motion and object blur are possible via the Octane render window with the animate button, what would it take from Rhino's end to make animating camera parameters work? I ask, because I can certainly create a post on the Bongo forum and make camera animation a wish for Bongo 3. So, if the camera parameters were able to be animated in Bongo/Rhino, would that mean that the Octane plugin could also animate them? I'm not sure how all of this works.
In (hopefully) the next release of the plugin, there will be an option to export the Bongo animation to OCS/ORBX format. This will allow you to render in Octane Standalone, and will have camera and vertex motion blur. This can be achieved WITHOUT the Rhino plugin needing to access the Bongo SDK (which is C++, and the Octane plugin is C#). If Bongo were to support animated camera parameters - these would not be accessible to Rhino, so the Octane plugin would need to use the C++ Bongo SDK, which is substantially more work that what is planned for the next release. Plus, I doubt the Bongo devs would add a parameter like Focus Distance to the camera, if Rhino were not able to use that parameter (although perhaps Rhino6 will have DOF?). So in summary....I think you are getting to the point where you are hitting the limits of Rhino/Bongo, but which are fully supported in a dedicated animation package (like Modo). For example, the OctaneRender for Modo plugin allows the animation of the Focus Distance.
Also, I'm asking this for a colleague, but also curious for myself. I've been training a group of my clients in Rhino and Octane. The use Blender and now Rhino and Blender. One of them asked me today if the purpose of the ORBX format was so that a model could be set up in one program with materials and lighting, and then "seamlessly" transferred over to another modeling platform supported by Octane, like Blender or Modo. Is that the purpose? If so, that really intrigues me, because I'm a big fan of both Modo and Blender. But I need Rhino to create most of the model because a lot of what I do is manufactured. But . . . if I could create a model in Rhino, create lights and materials, do the still shots and hi res stills with Rhino and Octane, and then bring the model with all of it's materials and lighting into another package when an animation is needed that requires something more complex than Bongo can handle . . . well, that would be pretty awesome.
No, an ORBX package exported from Rhino cannot be opened in OctaneRender for Modo/3ds/Blender/etc. That is not the intent of the ORBX format. However, an ORBX file CAN be opened for the Nuke (and perhaps AE) plugin. However, if you export an animation from Rhino as OCS, there will be an ABC file, which CAN be loaded into Modo/3ds/Blender, and you could then bring across the materials from Rhino (via the LocalDb). Its a bit of work, and the cameras would not come across, but you get the idea.....
I think I would be tempted to modify the Octane Standalone camera animation script to do what you want - since that solution allows you to bring across the entire Rhino scene with Octane materials.
