Nudge, Nudge...
-----------------------------------
Hmm... That's odd, my post from an hour or so ago didn't register. Never mind, it was probably incoherent. What did I say ??

Okay, between the worst of my 'flu-like symptoms, I've investigated why I could not tweak an OBJ with eg Wings3D then plug it back into CR2 or PP2 and have a model appear...

First thing, the original OBJ was last seen by UVUnWrapper, which arranges things in a different order to Wings. Easily fixed: I'd never used UVUnWrap (Classic), but it was among my many downloads. Unzipped, installed, it put original OBJ back in the same format, as good as new.

Bad news, nudging even one vertex changed everything. The OBJ file grew in size, the v/vt/vn etc counts changed, the model vanished.

Did I miss something about quads vs triangles ?? Could I have left an option somewhere along the way that converted the mesh ??

I really, really hoped that I could tweak OBJ files, rather than learn to build and re-build each conforming model's JPs and Hierarchy after every little vertex nudge...

D'uh, my head hurts...
