Hey Dr. Sassi,
Thank you very much for your time and workaround! This is definitely way far than I even could though inside C4D, and I see your solution working, yes!
The good news is that a Maya team was able to troubleshoot and find a solution on this morning. They used a plane behind the text object and animated the plane mimicking the movement of the text. Then they transferred the UV from the plane to the text, I guess in a frontal projection or something like this. It was a fake UV but it kinda works for the purpose.
Also, I was thinking to use the Mesh deformer in C4D applied to a text object (identical as the original animation) and try to deform it using the animation as a cage, but I had not luck on this side - possibly with your knowledge that may be a workaround?
Well, nothing to worry about now! Thanks again for all the time invested on this and for the knowledge! Really appreciate it.
Many thanks,
Thiago
