I export as obj to Vue esprit. Never had any problems with it.

My settings are:

scale: 1000%

Ignore invisible nodes: checked

Use bonewelds: unchecked

Remove unused vertices: unchecked

Write UV coordinates: checked

Write normals: checked

Write object statements: checked

Write groups: checked -> use existing groups: checked

Write surfaces: checked -> write material library: checked -> collect maps: checked

 

I hope that helps. :)
