I resurrect this old thread because I recently did try LightRave with the Open VideoToaster CD image downloadable from DiscreetFX website. 
I made a little video. Lightwave 3D 3.2 works perfectly without Toaster with Lightrave. Here's the video (sorry for the typo on the floppy label 

 and for my bad English) 
https://youtu.be/SenNfDjEJjQ@jandreas I understand that you were the Lightrave coder. Can you give permission to put Lightrave adf on the Open VideoToaster website? It'll be a great gift to Amiga community and a great piece of historical software preservation.
If anyone is in contact with jandreas can point him to this thread, please. Thanks
