What is the warp modifier for, and how is it used?
Even when I fill in the From and To fields, so that the modifier is not red, I still can not figure out what it is so post to do.

Warp modifier


When I set up the modifier just like is shown in the manual, it does nothing.

The warp modifier can also be used to wrap an object: the to object controlles the direction to where the from object is wrapping the object (holding the modifier).

The warp modifier produces results similar to user gestures of

proportional editing.

The blue cube has a high vertex density. The from and to are animated in rotation.

The warp modifier deforms a mesh as if some force acted on it. The force starts at the "start" object and ends in the "to" object. The "start" object center and the radius determine which vertices are affected. The texture option has an effect similar to the texture of the displace modifier.

You need to increase the radius in order to see something, because there is no effect if the radius is smaller than the distance from the source. The scale and rotation of all three involved objects does matter (even if the "from" and "to" objects are empties), so it is best to apply the scale and rotation before playing.

Also note that the manual uses a grid, not a plane without subdivisions.
