CINEMA 4D R11 Quickstart – Dynamics
Before we play the animation again we will change its length. To do this click on edit / project settings and
change the “Maximum“ parameter to 300 frames. So that our solver object doesn’t stop the animation at frame
75 we will also change its “Stop“ parameter to 300 in the dialog field “Main“ to the right.
The animation is still pretty boring but we can at least demonstrate what is expected of Dynamics: Two bodies
fall and collide! Two further settings are still necessary to make the objects behave the way we want them to.
Click on the solver object and set the value “Energy Loss“ from 5% to 2%. This keeps the objects from being
slowed too drastically. Now set the “Strength“ value in the Gravitation objects’s “Field“ dialog box to 3.
OK, here we go. Click on the play button and we’ll be finished with this chapter. If the objects are not behaving
the way they should it could be due to the method of integration of the solver object and its oversampling
setting. The higher the oversampling value the more exact the simulation of the solver object. Of course the
time needed to calculate the simulation will increase as well.
Important Tip: If one of the objects is not positioned properly you can only change its position once the solver
object has been deactivated. After repositioning the object you must select “Dynamics / Initialize Object“ or
“Initialize All Objects” in the main menu! Then the solver object can be reactivated.
Try different property settings and see what changes to the Dynamic tags, gravity object and solver object to.
Changes and variations are endless and need to be fine-tuned a lot until the result you want is achieved. Now
let’s move to the second part of this Quickstart Tutorial: The soft bodies!
