Im not finding a solution for my quest,
Did every thing like welding the nearest vertices, even though i'm getting an error it says
" <car> has these verts too close to each other: #(20340, 1603). please move them further appart."
what is this kind of representation of #( 20340, 1603), if v can figure out the culprit vertex so that v can do some tweaks to that particular vertex.
i have waited long enough but no solution .
