Redshift for C4D R21

[hang-single]

hi,
Is there a working paid version of Redshift for Cinema 4D R21 somewhere?

Hi hang-single,

To my knowledge, the options are R25 and up.

There was a version for R21, but since that was around 6 years ago, I'm not aware if that is available as a new license or if support is given for the current OS.
If it is available, make sure to know what version of Redshift 3D it is.
