"they are directly tweaked in C4D and exported via orbx command."
I think the "orbx" command is not in C4D demo plug, I guess it is a Stand alone feature.
"It's possible to export some scenes with full setup, but it's not appropriate for big scenes."
"..possible to export some scenes.." will try to look into limitations, without the "live Viewer' C4d "edit in Stand alone" feature, the learn curve tricky.
"Also AE plugin can be used on different layers with different objects/orbx scenes."
I guess I'll have to purchase when available.
"So it's possible to combine different objects with different kernels."
If the very useful lighting of Octane can be passed through, you will have a winner!
"But still have lacks and need more improvements."
The community that deals with "broadcast", I suspect, will be a good revenue generator for Otoy as After effects/Adobe has not improved much of late and Ae has a huge portion of Broadcast market-special effects.
Thanks for the replies, your hard work and best wishes for Octane to be the Go TO between Modeling UIs and Effects UIs.
