Join Aaron F. Ross for an in-depth discussion in this video Creating dynamic objects, part of Maya Dynamics: Creating Simulations (2012).
Heading out of those Aim Constraints now I am ready to create Dynamics.…I'll go to the Dynamic menu set and I want to make all of these spheres…active rigid bodies.…So I'll just select all those spheres, go up to Soft/Rigid Bodies, and Create Active.…We also need to have gravity applied. With those spheres still selected,…I'll go up to the Fields menu and choose Gravity.…And there's my Gravity node and move that out of the way a little bit, rewind…and play my simulation, you'll see that the spheres are falling and they're…falling very, very slowly.…
And the reason for that is that I've built my scene at 1:1 scale and the…gravity is expecting this scene at 1:100th scale.…To correct for that now, I'll select that Gravity field and in the Channel box…I'll set that Magnitude to 980.…Now I've got physically accurate behavior.…Those spheres are real-world size and they're only an inch or two above the ground.…So it wouldn't take them very long to fall to the grid plane.…
