Since I'm not yet familiar with IM's modeling tools, I place
my markers and then export the Lightwave scene. I load
the scene into Layout with all the nulls in place, and then
run a free plug-in called "NullsToPoints."
What that does is it saves a lscript in the same directory
as the loaded scene file. You go into Modeler, and then
run the lscript that was just generated from Layout, and
it generates a bunch of points in Modeler. Then I start
connecting the dots and creating geometry there.
Or you can just use ImageModelers modeling commands
and IM will export the object with the scene that it goes in.
