Horde3D

Hi everyone,
previously I have worked on my own small render engine and used some others but I wanted to skip all the setup work, etc....and so I switched to Horde3D
I am fairly new to Horde3D but I am really loving the engine. Thanks for putting it out there.
So far, I have brought my own content to the engine and gotten familiar with the general structure of Horde3D.
Now, I am at a point where I would like to voxelize the whole scene and implement voxel cone tracing for soft shadows.
With some of you knowing the engine inside out, I was wondering whether anyone has every done something similar and/or if you could give me advice where to best put the code.

Thanks a lot

Sorry I'm not familiar enough with this technique to give any advices
