(Space Warps)Space warps are nonrenderable objects that affect the appearance of other objects. Space warps behave somewhat like modifiers, except that space warps influence world space rather than object space, as geometric modifiers do.
When you create a space warp object, viewports show a wireframe representation of it. You can transform the space warp as you do other 3ds Max objects. The position, rotation, and scale of the space warp affect its operation.
Surfaces deformed by space warps:
Left: Bomb
Right: Ripple
Rear: Wave
