What is the best way to stretch an object so that the texture map stretches with it? I can see the idea of creating a morph of the beginning and end position, but what is the best way to achieve the end position of the object? I want the end position to to be in the shape of an hourglass. Thanks. -James Franssen

>>What is the best way to stretch an object so that the texture map stretches with it? When you move vertices the mapping coordnates move with them so it's kind of a no brainer. Now bear in mind that the orignal mapping coordinates are going to stretch on a vertex to vertex basis – unless all the vertices are being scaled/rotated uniformallly the mapping for the _entire_ mesh is not going to be uniform. – Phil

>> Well, actually, I was trying to get a suggestion on how to give the object a "stretched" look, like an hourglass shape. Gotcha ya. The best way to make an elegent hourglass is actually to loft it. If you have an exsiting mesh and want to"pinch" it in to an hour glass then you need to perform a series of 2D Scales to rows of its center vertices (select the whole middle vertex group and scale 90%, deselect the top and bottom rows and scale another 90%, deselect……and so on..) – Phil

> I was afraid of that 🙂 Don't be afraid, James. Unless you've got a very unusual object, this is a no brainer. Just use Select/Vertex/Quad, draw the "box" around the center of your object, press the "X" key (to have operations performed around the object center rather than world coordinates) and do a 3D scale from the top view. It will take all of about five seconds (you can even copy the object first and end up with a morph target).
