Thank you very much Dave!
The thing is: We’re talking an only 10 seconds long spot. I don’t know if it’s worth it to learn a new software, I think I could handle the render time.
On the other hand, I’ve been doing some basic usage of C4D before (well, ten years ago) and I remember it to be pretty straightforward and quite easy to learn.
But since I don’t even have a solution for my lighing problem, I think the best thing to do is refreshing my C4D skills and do the lighting there…
