Toon Boom has announced version 3.5 of its Toon Boom Studio cel animation software, which will ship in September.

The upgrade adds predefined animation 'elements', which allow objects and drawings to be quickly animated. The interface has been simplified, according to Toon Boom, to make animation work more efficient.

A real-time drop shadow effect has been added, and improvements have been made to tools such as the Scene Select Operator, Contour Editor, Color Transform, and Texture and Gradient Mapping. The software also gains a PDF export function.

Toon Boom Studio 3.5 will be available for Mac OS X and Windows, and can be pre-ordered for $299.99 (around £160), with upgrades from versions 2.5 and 3.0 costing $99.99 (around £52).
