CINEMA 4D R11 Quickstart – Dynamics
Zoom out so you can see the entire scene. Tilt the plane object in the “B“ angle by 15 degrees and place the
other objects in the approximate position they are in, in the following image.
The cube and the sphere should be placed quite a bit above the plane, each over one half of the plane as seen
from the top so they don’t cross paths. Drag the sphere, the cube and the plane into the solver object and
convert them to polygons (Main Menu / Functions / Make Editable) or click on
The next step is the assigning of Dynamics properties using the Dynamics tags. For soft surface properties we
would need to use Soft Body Spring Tags. Since we want to let the sphere and the cube fall onto a surface
without them bouncing off, we need the Rigid Body Dynamic Tag. Apply to each object a Rigid Body Tag (right
mouse button / Dynamics Tags / Rigid Body Dynamic). If you play the animation now, you will notice that all
objects fall out of the picture. Of course this is not exactly what we want to achieve for this scene. This happens
because all objects possess a mass. We need at least one object that does not leave its position so the other
objects can collide with it. This is a job for the plane. In the dialog field, give the plane a “Total Mass“ of “0“.
When the scene is played now the plane object doesn’t move but we’re still not happy with the total result.
The objects fall through the plane! The reason is that no object has a collision property. Give each of the three
objects a “Collision“ value of “Full“. To speed up your workflow you can select all tags at once and make the
change to all objects. (You could also use the settings “Box“ and “Ellipsoid“ – these are significantly faster than
“Full” and are often sufficient for simple objects).
