Any ideas to achieve this style?

[life-board]

Hi! Anyone to help me reproduce this next reference in either C4D/AFX or combination of both?

[Dr. Sassi]

Hi life-board,

Thanks for the question, which made me invest the time I would love to have for a while, for myself, there was obviously no time to explore it. But when I saw it for the first time, I was intrigued. So thanks for the push

It looks to me like a reflection of a hidden object.

Not that I had that answer in a library, but getting it very simplified took me a while. If I had to do it for a project, my setup would be more separated in AOVs and compositing. Here, my intention was to get it "in camera."
One significant influence is the roughness of the floor.

Please have a look here:
CV4_2024_drs_24_RSal_41.c4d
CV4_2024_drs_24_RSal_42.c4d

The version "42" might come close.

My best wishes

[Dr. Sassi]

P.S.: Here is a 60-second run-through of a quick setup. Please note that the Initial spline can be adjusted at any time.
The main animation is in the MoSpline Object tab.

Amazing, v42 is a very good setup and v51 nicer approach. I will build from there my setup.

As always, many thanks for your help.

You're very welcome, life-board,

Enjoy your project!
