Thanks Guys
Wouldn't have figured that one out!
One other question - I added a ParticleToGeo node and after the scene added a
writeGeo.
With both obj and fbx and set on geo - I couldn't get anything written out from
the writeGeo that is the file seemed blank - any tricks here or a bug?
Thanks again
Howard
