Hi PaQ, unfortunately it is somewhat more complicated to do the same thing for LWO files.
The way that OBJ files are structured, all that tool actually has to do is strip out a bit of labeling information and just pass through all the rest of the OBJ file and that merges it into one logical piece.
LWO files are not structured like that, they don't have just one ongoing list of all vertices like an OBJ file, each different layer/object in the file has its own individual chunk of points and polygon information instead of the points being counted more globally through the whole file like OBJ.
So to do the same thing in LWO would have to do more work than the OBJ one, it would have to combine sections and remap polygons. Not fundamentally difficult stuff, but enough time consuming that I don't think that I can cook that up for you right this moment...
It sounds like you are running into some bugs with Modo - I mean the big question is why can't you do a combine operation in Modo and keep the vertex map alive? That would seem to be a pretty nice basic operation to have available there.
And also the OBJ file has the same basic polygon data in it as the LWO, so there isn't really a good reason why the OBJ should not work as well as the LWO... Modo is sensitive to which point is defined as the first point in a polygon, and it seems like their OBJ reader does not do a good job of rotating the polygon so that there is a convex vertex as the first point. Of course it would be even better if Modo was not so sensitive to only look at the first points of a polygon to determine its direction and instead look through all the points...
I'm not really sure what I can do to help you just right at this moment... Isn't there any way to use scripting in Modo to automate some of the things that you want to apply to the 82 objects, is it that you want to apply the same materials to all of them or something like that?
