Join Aaron F. Ross for an in-depth discussion in this video Keyframing field magnitude, part of Maya Dynamics: Creating Simulations (2012).
One fun thing you can do with keyframing attributes for rigid bodies is keyframe…the Magnitude of a field.…That way we can cause the field to have effect only during certain times of the animation.…In this version of the bowling alley I've deleted the bowling ball and I've…deleted the field that we created in Chapter 2.…And I'm going to new field that only affects the pins and I can make those pins…fly through the room without having been struck by anything and I can have that…happen at a specific frame in my Timeline.…
I'll go head and select all the pins, making sure that I haven't…selected anything else.…And in my Dynamics menu set I'll choose Fields and we'll do a Radial field.…It's created at the Origin. I'll just move it up a little bit and then in my…top view I'll move it back and position it so that it's behind the pins;…that'll be more dramatic.…It calls the pins to fly outward.…Now I have disabled Solver Evaluation-- remember here Modify>Evaluate Nodes-- and…that's really the best thing to do when you're trying to set keyframes for field…
