If you are looking for a place to start with dynamics in Cinema 4D, then look no further. Sean Frangella shares a whole slew of tips and tricks for setting up custom cinema 4D simulations. This includes both rigid body and soft body simulations, using gravity and forces, along with Cinema 4D native elements like the MoGraph cloner, and more.
Soft and rigid body physics can be a great way to add realistic motion and secondary action to your motion graphics scenes, but some people find it intimidating to incorporate dynamic elements beyond playing around with things. This is a great starting point for simulated physics.
