Hey Chris,
I am tackling this very thing now. I know it has been a few months since we
talked, but I was wondering if you had any more info. I have been trying to
do the thing where you use the alpha channel from the diffuse map, and I
could not even get that working. Do you have any examples of that working?
Anyway, let me know if you have any new ideas. I will certainly let you
know when I crack this egg.

Rick, I use the LWO object loader, but not the LWS loader. We use LWO2
as the preferred
3D object transfer format between our VNS/SX authoring tool and our
OSG-based NatureView
realtime viewer. It's much less limited than 3DS, and more compact than
formats like OBJ.
One thing I've always had trouble with is that the LWO2 loader doesn't
support a
transparency texture image. You can put transparency into the alpha
channel of the diffuse
color texture image, but this is a non-standard way of doing things and my
LWO writer
doesn't support this quirk. Obviously OGL is more restrictive with
image-based
transparency than LW is, but I'd love to be able to make the LWO plugin
automatically copy
the transparency image over to the alpha channel of the diffuse color
texture if they are
the same size and mapping mode.
I'm not in a situation where my development tasking allows me to hack on
OSG right now,
but if you're taking requests for improvement to the LWO loader, I figured
I'd register my
request.
