Welcome to Toonit. The Toonit Matrix is where you can fully leverage your imagination by creating new assets and backgrounds that incorporate the various 3D assets and components from the marketplace. You can either set it to free or for a fee for other Toonit users to use.
Note that during the closed beta release, all matrixes will be set to free and monetization opportunities will not be available.
