hmm... figured out the lack of cooperation... tried to import far too large meshes... worked better when going for a smaller mesh.

poly cruncher is a bit useless since the goal is to have a complex 3D terrain mesh, and deep exploration would not work... (wrong processor)

any way to chop up a 3D mesh into smaller segments?

hmm... We're having a tab bit of trouble importing a terrain mesh we've made... We keep running out of memory...

The file size on the obj file is 374mb.
Any solutions?

If importer cant be solved for it... any other way to get it into sketchup (perhaps in pieces?)

Not sure about the polygon count, but its a large number. Probably somewhere around 2m.
