I am modelling two milk cartons, they are exactly the same shape, one is just twice as tall as the other. I have a perfect model and uv map for the shorter version, but I now want to create the taller version. I have duplicated the smaller model, then spilt it in the middle, moved the two halves apart, and then stitched and sewed the edges together to make the taller model.
I am struggling with editing the UVs to match the new model so my taller artwork fits the model perfectly.
Can anyone think of the best way to do this?
