The Space Warp behavior lets space warps, such as wind or gravity, influence a crowd simulation. You can use it to apply space warps in the Forces and Particles & Dynamics categories to crowd members.
In particular, use the Space Warp behavior to tie delegates to a Vector Field space warp, so that they avoid penetrating an irregularly shaped object while following its contours.
None (label)—Click this button, then select a space warp object.
Color Swatch—shows the color used to draw the Space Warp force vector during the solution. Click the box to choose a different color.
Display Force—When on, force exerted on the delegate(s) by the Space Warp behavior is drawn in the viewports as a vector during the simulation solution.
