How to install Reaper VSTs into cubase

Hello friends.
How do I Install Reaper VSTs into Cubase?

I copied the dll file to the VST plugins folder. Now I am able to insert it, but the sliders are missing.

I can change the parameters via its number boxes, but to no effect. Sound doesnt change.

BTW, We´re talking about reagate here.

Any help is highly appreciated.
