mesh question

If I modify a mesh procedurally through a javascript and remove one or more vertex does unity automatically modify any triangle that used those vertices?

Does it just remove that triangle from the triangle array?

Also what happens in the reverse situation, if I remove a trangle, what happens the the vertices array?

I haven't tried this yet I was just wondering if anyone knew the answer already.

 

No, you get an error.

This is OK - it will just ignore the unused verts.

 

thanks
