[away3d] 3D optimisations

[Ben Gannaway]

Hi all,
Are hierarchical models supported for any of the geometry importers in  
Away3D?  My (.obj) model is currently textured only on the top level  
of the hierarchy, and I'm not sure if it's because of the way I've  
exported or imported.

Also, Away demos such as Green Planet display an impressive number of  
polygons.  Aside from the fog filter, can anyone offer any  
optimisation tips for calculating larger numbers of triangles. Are  
some model formats faster than others? I seem to be working with far  
fewer triangles and already noticing a drop in frame-rate.

Thanks,

Ben
