I've put Unity up for my Procedural Voxel projects and I've integrated PolyVox into my C++ Game Engine which uses Ogre3D and a bunch of other Libraries for different things. I started playing around with Generating Procedural Trees using the Space Colonization Algorithm - http://algorithmicbotany.org/papers/col ... .large.pdf

They still need some work but I think once I get them finished they will look pretty cool.

Here are some screenshots so far:

Looks good - you might also find that running the LowPassFilter class over your tree helps it looks more natural?

Well I got the Low Pass Filter setup and working. It makes the terrain look good but it destroys the trees. The Tree branches are only a single voxel so I'm guessing the Low Pass Filter removes them. Just gives me a reason for adding width to the Branches.
