There is a workaround to help RS 3.0.50 and older find the TFD plugin:
- Install TFD for both C4D R24 and R21. If you don’t have C4D R21 installed, just specify any folder to the TFD installer in the R21 row.
- Copy the file TurbulenceFD_R21_1476.xdl64 from the C4D R21/plugins/TurbulenceFD folder to the C4D R24/plugins/TurbulenceFD folder
- Rename the C4D R24/plugins/TurbulenceFD folder to TurbulenceFD_C4D_v1-0_1476
- Restart C4D
This process also works for R23.
