I shared it and the code is still there. I published it so other developers could pick up the ball, but nobody did. I even made it so that nobody had to do programming to build the GUI - just fill in the properties to define what is needed to edit the configurations. I made the converters so simple that they fit on half a page. And yet ... ignored.

I wish I had time to work on this but I don't. One thing I know is that if you want to build a framework that can be used for multiple target renderers, you have to actually do it with multiple target renderers as early as possible. Otherwise you only theorize about the commonalities and differences and get them wrong.

Also I think that it would be really cool to modify the target renderers so that they are procedurally compatible with Poser shaders for pattern generation. To that end, people should be working on porting Poser's nodes to Yafaray, Luxrender, etc. If I end up doing that all by myself, then I'll charge for those changes.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
