On what version of Cycles is Bricklink Stud.io's Eyesight renderer based?

they built using some of our our svn libraries

Doesn’t that mean we can force them to open-source it?

There’s nothing wrong with using our SVN libraries, many libraries in there have a more permissive license than blender has.

I think that sounds like a good idea.

I certainly won’t stop you from executing what you deem a good idea.

I will stop you from necromancing a 2 year old thread though
