Thanks for sharing your findings, Jerome Olivier.
As I do excessive research before I do a tutorial, I have no answer to this right now. As I said it can (!) but it mustn’t :o). So, take it as a heads up, but I stick with it for now:
I can’t say anything at this moment, it takes some time to get this explored. In C4D we have way over 1,000 functions and options, combine three of them and you are (theoretical) in the billions of options. If somethings works or not is always dependent on the context, the release, but normally things work of course. I’m normally carefully with my advices. E.g., think about Net-Rendering, Team Rendering, different Versions, when was the change if there was one. Which platt-form (OS) etc.
If you find a reason why one would have the need to feed a cascading information into the scene, and not use the information directly on this node, I will check it out. So far I haven’t found one, only trouble in some cases at that time.
All the best
Sassi
