Yes, it will support them. Hulls don’t work in the current beta but will in release version. (In terms of misaligned hulls in SMDs, this isn’t something I’ve had issues with when using the QC importer in WW. But I don’t do much importing and only use the QC importer when I do… so never import SMDs one at a time, etc.)
At this time, there is a drop-down to change which bodygroup and another menu for selecting submodels (as in HLMV). I have planned a little manager to display all bodygroups at once and the current selection so you can pick and choose from a larger list. That function will probably not be in the initial release.
At the moment, the normals are set with Mesh.setNormal() but this has problems when collapsing to ediable poly. We are looking into fixing this to be compatible with explicit normals that can collapse to epoly.
