Working on big updates to Wicked Engine's voxel GI, now it supports anisotropic voxels and clipmaps.
Anisotropic voxels means each voxel has a directionality, so voxel resolution doubles 6 times, once for each face of a cube. Sampling the anisotropic structure requires 3 texture lookups instead of one.
The clipmap is a voxel cascade structure, each level covers a twice as big area compared to the previous level, while using the same resolution. Only one clipmap is updated per frame, so the result lags a bit.
The performance is currently very slow, this will need to be solved before competing the update.

I made a Tile Based Forward renderer for Wicked Engine. It can support hundreds of lights without a need for a G-Buffer. It supports the ligting of alpha blended/transparent geometries and particle systems trivially as opposed to deferred rendering.
I currently use a depth pre-pass to tightly cull the lights and eliminate overdraw.
This excellent blog helped me a lot in the implementation: http://www.3dgep.com/forward-plus/#Forward
