Tweak Software

Tweak Software originated as the Research and Development division of Tweak Films, an award-winning visual effects company with a tradition of advanced technology development. Tweak is located in San Francisco, California. (You can read about the history of Tweak Films here.)

Tweak's team has a long history of developing cutting edge VFX technology including: the first particle system (Dynamation) which led to breakthrough effects in films such as Twister; ILM's first generation rigid body dynamics, cloth systems and creature modeling tools which made Star Wars: Episode One possible; ILM's facial motion capture technology; and ILM's Zeno platform. Tweak has built on this experience to develop unique next-generation tools for water, dynamics, particles and procedural effects that have made possible projects such as the water in The Day After Tomorrow and the collapse of the Barad Dur Tower in the Lord of the Rings: the Return of the King.
