I say that mainly because I have yet to get V4 looking good.  Objects look fine, but V4...not so much.  I'd love to see a, "load V4, this texture, export to obj, import into Octane, then do this, this and this to the materials and render, and it should come out looking like this"  type of thing.  I've been piecing together Paul's tips here, but my results are less than stellar....

Start will no SSS, so just use a glossy material with very very small specular.  That should get you 90% there!  Make sure kernel is set to pathtracing (direct light is preview mode).

I would love to participate in the beta for the exporter.

There is a link on www.refractivesoftware.com calling for beta testers.
