An experimental movie clip of cloth motion using Blender and Freestyle. The pleated skirt and simplified legs are made of ordinary meshes, while an invisible mesh is placed inside the skirt (as if it is a kind of backing fabric). The invisible mesh is deformed by a soft body modifier, and its motion is transferred to the skirt mesh through a combination of empty objects (parented to vertices of the invisible mesh) and an armature object with copy location constraints (having the empty objects as targets). This indirect motion transfer technique is employed in the rigging of Proog in the "Elephants Dream" open movie elephantsdream.org and briefly described in Tony Mullen's "Introducing Character Animation with Blender" (Chapter 14). The main advantage of the technique (over directly applying a soft body modifier to the skirt mesh) is high controllability of cloth motion: Keeping the shape of pleats while avoiding undesired self-collision among the pleats is a matter of usual mesh editing in the indirect technique, whereas achieving the same results using the direct soft body method is a nightmare.
