All the meshes are always imported in obj mode.
Lighting is only daylight mode from Octane Render.
A little bit more complex in the Sequence 3 of Test Drive A.D.

@Refracty :
I have not yet started the calculation. Just at the end of the storyboard.
My new machine is expected to greatly accelerate the process.

For the great Aoktar plugin, unfortunately I can not use it on my movie.
The scenes have about 500 materials and as there is no export OCM, it would be a very long task to convert them.

As said Beppe, support live-db will likely be available in the final release.
Surely, the perfect solution !
