Applying #LOD modifier to Lingo created meshes 2003-12-01 - By Mark Hill
Back
Hi,
I think Christophe means the SDS modifier... but as he points out
unfortunately this will only increase polygon density, not reduce it.
If you really want to use the built-in LOD, you'll probably have to
parse the models out to OBJ format ( or something similar... OBJ is the
most straightforward format IMO) import them into Plasma, Max, Maya,
LightWave, C4D or some other 3D app with a decent W3D exporter ( is
there such a thing ?) and re-export. Possibly the OBJ converter that
Macr makes available for Windows and MacOS9 might add the required data
also... not certain on that point.
Basically, not a really straightforward operation... :(
