Here are some simple examples showing the power of softbody physics.

A Bouncing Cube

The Process

First, change your start and end frames to 1 and 150.


The timeline.

Then, add a plane, and scale it five times. Next, go to the physics tab, and add a collision. The default settings are fine for this example.

Now add a cube, or use the default cube, then enter Edit Mode to subdivide it three times. Add a Bevel Modifier to it to smoothen the edges and then to add a little more, press R twice, and move your cursor a bit.

When finished, your scene should look like this:


The scene, ready for softbody physics.

Everything is ready to add the softbody physics. Go to Properties ‣ Physics and choose Softbody. Uncheck the soft body goal, and check softbody self collision. Also, under soft body edges, increase the bending to 10.

Playing the animation with Alt-A will now give a slow animation of a bouncing cube. To speed things up, we need to bake the softbody physics.

Under Soft Body Cache change the values of your start and end frames. In this case 1 and 150. Now, to test if everything is working, you can take a cache step of 5 or 10, but for the final animation it is better to reduce it to 1, to cache everything.

When finished, your physics panel should look like this:


The physics settings.

You can now bake the simulation, give the cube materials and textures and render the animation.

The Result

The rendered bouncing cube:
