AshMantle: The mesh is single surface (1 texture) and the tris share the same group.
Bob3D: Thanks for trying to explain things but I think my problem comes down to me not knowing exactly what welding UVs does and what it's used for. :P
I understand that the 3D welding of verts actually affects the geometry but UV welding has me a bit stumped. When you say:
I don't even think UV welding is related to my problem, TBH. Let me explain with a simple example:
(pic 1) Here are 2 strips that I want to use the same area of texture because they are the same size/shape. I do this by copying the UVs from one strip and pasting them onto the other.
(pic2) Here's the result which 'looks' exactly how I want but some of the tris have become unwelded...
(pic 3) I've packed the UVs here (using 'separate by connectivity') just to prove that some tris have become unwelded.
It seems the operation of copying and pasting the UVs from one strip to the other has broken up some tris. I don't understand why. I have also verified this in Blitz3D itself: I have a prog that lets me pull the verts of a mesh apart.
Can you - or anyone - shed any light? :)

The second type of weld, is for what u're aiming.
