Hi Bart,
Fur, as far as I'm aware, isn't in the data Cinema 4D provides to Redshift. Here, the Hair option needs to be used instead.
I would suggest limiting the Segments of the "Guides" and "Hair", and setting Hair> Dynamics > Rigid after the Initial state is "recorded".
Since Hair works, it should be possible to get Fur working, but it needs more input. Please use the "Share Your Ideas" so that the need for that is more clearly seen. Thank you very much.

I used Noise here to keep the file small.
