Hey, thanks for the headsup, can you hit us with a link?
 never mind, found it. http://www.werkkzeug.com/
It says it's free to limited extent
Yes. Instead of keeping you and the number of artist working in your toolchain limited, we are offering .werkkzeug3 TE for free. Just register, download and use it. You can even save the textures as BMP and use those images in your projects for free.
A bit off-topic. I've followed the links on the aformentioned website and found this: http://www.theprodukkt.com/debris
Jawdropping stuff. Really recommend you to watch this.
