Here comes version 0.05. The main new feature is the automatic conversion of texture mappings like spherical, cylindrical, flat, shrink, ... to UVW coordinates. Keep in mind though, that you usually can't completely reproduce those projections using UVWs. There will be issues if the geometry is too sparse or at UV boundaries. I started doing that conversion by myself, but this morning I found a function in C4D that does the work for me, so I didn't have to implement it myself. And most of the times it's doing a pretty decent job. Try it out

I hope the bug of the error dialog after launching Octane on Mac OS is now fixed and the texture of the specular colour channel gets exported, if it's specified and no reflection channel is used.
And last but not least I have added a little test: If you open the CINEMA 4D console window and the exporter dialog and launch Octane via the "Render" button, You should see in 1 second intervals the line "Octane is running" as long as Octane is running. If you close Octane, the text output in the console should switch to "Octane has stopped". When you close the exporter dialog, the messages in the console window will stop. It would be nice if a few Mac and PC users could verify if this actually works. I will need it for the animation export. Thanks.
These are the PC builds of the plugin:
CINEMA 4D R9.6 (32/64bit): CINEMA 4D R10.1 - 11.0 (32/64bit): CINEMA 4D R11.5 (32/64bit): These are the Mac builds of the plugin:
CINEMA 4D R9.6 (32bit): CINEMA 4D R10.1 - 10.5 (32bit): CINEMA 4D R11.0 (32/64bit): CINEMA 4D R11.5 (32/64bit): Now I will start working on the animation export

Cheers and happy rendering,
Marcus
