Michael Hetrick (https://www.unfilteredaudio.com/) has released it first block of modules to the public. These are ported from Euro Reakt for Reaktor 6, he won’t port all the enitre collection (gosh! it’s just 140+ Blocks!) but only a part, and they will be free.
At the moment you can only find them on gitHub as Source Code, not as compiled versions.
