Deforming meshes at runtime

[Sackmore]

Hello:

Is it possible to deform a mesh at runtime?  For instance:  I have a hunk of steal (which is a boneless mesh) and i want to strike it with a hammer (which is another boneless mesh), can that strike produce an dent within that hunk of steal?  How do i go about doing this?  Also, if this is even possible with Meshes, is this possible on Actors?

thank you,

yes I have done so.

BUT
a)
you can't do it with meshes loaded from a 3DS (and possible others).  I was only able to get it working correctly for .x file meshes.


b)
You have to do the math/physics your self to determine what vertices need to be adjusted and apply those adjustments your self.
