Hi
I already talked about that here:
http://forum.jogamp.org/Official-Homepage-and-gitbub-for-Ardor3D-tp4032362p4032384.htmlJogAmp's Ardor3D Continuation is still maintained unlike the "official" Ardor3D. I have to update the binaries soon. Maven support will be harder to keep working but the rest is ok.
Renanse is a free citizen, he did its best, I don't blame him. Only a very few people contributed but tens of developers have used this engine.
Best regards and don't worry. I need to maintain it for my own project too :)
