Micromesh export extra Vertcies

[mash]

Hi,I exported a terrain using the Micromesh exporter.
The file size is 386,407 KB.

I load that Obj into Modo and it has 3310899 vertices, 3310899 edges and 1103633 polygons.
If I select any single vertex I'm told that there are any where from 4 to 9 extra vertices in the same location.
If I select any edge there are 2 to 4 extra edges in the same location.

If I run a merge vertices in Modo with a fixed distance of 1mm it gets rid of all the extra vertices and edges.
2846436 vertices are merged
The new stats are 464463 vertices, 1389545 edges and 1103633 polygons.
the new File size is 108,249 KB

So I'm wonder if the micromesh exporter is writing in the extra vertices and edges for a reason ?
Thanks,

Hi,

It's not actually exporting a mesh, it's exporting all the triangles generated during rendering. That's why you have full geometry for every triangle. I think if you want a more compact representation then at this time it's best to do what you did and use another 3D app to merge the geometry.
