> Hey I'm just wondering if the VXL/HVA docs are gonna be updated, specifically in regard to the 'unknown' variables. I'm making an RA2 editor right now and I'm also integrating a nice VXL editor in with it that I'm making and it'd be nice to know what those unknowns are if anyone does know.

The 'unknown', which is usually '2', is now understood to indicate the normals scheme. This value is '2' for models that use Tiberian-Sun normals format, and '4' for those that use Red-Alert-2 format. You can safely use Tiberian-Sun format in the RA2 game too, though.

If it is helpful, look over the code to the Voxel Section Editor II - The sourcecode is in every download.
