Hi

Med's Mesh Tester keeps saying that there is a hole (open) mesh but I can't see any hole.

you cannot see everything that a program can see.lol

if you have 3dSmax try opening the model.
and goto Modify->Mesh Editing-> Cap Holes.

thank you.

I know this thread is a little old, 007, but do you know of a similar 'fix'
for open meshes in lightwave 9?
(non-version specific answer will still be appreciated)

Thanks
