Redshift volume shader greyed out


I am interested in TFD and trying the demo. But In the redshift volume shader all TFD options are greyed out. What is the problem?

Unfortunately, the Learning Edition does not support 3rd party renderers at all. I hope this restriction can be removed in the future, but for now there is no way to test the Learning Edition with 3rd party renderers.
The licensed version is supported by Octane, Arnold, Redshift and Cycles.

Hi Jascha,
i moved from the LE to full version () today. i use c4d and redshift (2.6.54 and 3.0.20 full version on R21 and R22. Tried to reinstall all parts and versions. Removed the tfd LE, added the full version again and again but the TFD in the Volume Material still greyed out.

Hope you have a idea!? Best regards.

Apologies for the delay.
There is a know issue in RS that requires TFD to be installed in the C4D plugins folder.
Please make sure TFD is extracted without any nested folders, such that the following path exists.
C:\Program Files\Maxon Cinema 4D R21\plugins\TurbulenceFD_C4D_v1-0_...\TurbulenceFD_R21_...xdl64

I did what I told you, but nothing has changed.

My version
Cinema 4dr23 (latest version) (genuine)
Redshift (latest version) (genuine)

Are you using the full version of TFD or the learning edition ?
