I took a look at what you suggested, and that's about as far as I could get. Doesn't seem a way or place to Paste to the Base. Perhaps you could do some screen shots of the process.

I did get DSF tools to work and have nice looking morph objects, and the poly count matches, but transferring Morphs isn't working in Lightwave this time. So, somethings different from than when I did the Toon Goldfish last year.

Best I could get the tool to do was make the resulting output OBJ's at 100X scale using Custom and 1%; it's not liking a .01 in the scale option.

If you look at wires of the .lwo result from the FBX export, and the DSF conversion, you'd think you're in home stretch. And if you select geometry by surface name, both models select the same polys.

But, turns out they DON'T have the same point count; an extra 1,144 in the exported morph. So without the point count being the same, kind a dead-in-the-water situation with morphs

I'll see if an OBJ exported out of DS fares better. Perhaps internal math differences in the FBX export is enough to throw it.
