UVW Map problems?

So, you have your model with a UVW Map (pretty much) all done but notice a vertex or 2 which need moving. You move the vertex, and end up with:



And so you re-create your UVW Map only to notice something else is out of place. Rinse and repeat. To prevent this, before you move a vertex, you can save your UVW Map:



Now move your vertex and watch that horrible tiling reappear. No worries, though:



Simply load your UVW Map and your texture will be reapplied correctly! Good times.

(This worked for me but it doesn't work all the time, if you delete vertices etc the map still has to be re-done...)
