Texture Lock <Shift+L>
This option toggles Texture lock mode on and off. Texture lock allows you to move a brush without disturbing the alignment of the texture on the object. With Texture lock disabled, if you move an object, the texture stays aligned with the original position of the object.
Tip: There are times when it is easier to resize or move an object to fit the current texture alignment instead of the other way around. In this case, disable Texture lock, move the object to fit the texture, then enable Texture lock to move the object with the texture aligned.
