blender image texture aspect ratio stretching

I was running into a problem with blender where I couldn’t preserve the aspect ratio of an image being used as a texture on a deforming surface. For rigid surfaces, the solution described here (basically, using an Empty) worked fine. But for a deforming surface, a better solution turned out to be to modify the “texture space” of the object. I didn’t even know that objects had a texture space, but they do (see bottom of this page, the “texture space transform” part), and you can change it. Just select your object, hit “T”, choose “Scale” and resize one of the dimensions (by hitting X, or Y, or Z) to get your aspect ratio back to what it should be. Yay! I wish I’d known about this earlier…
