PRO PACK -- KEY FEATURES Using new plug-ins included in the Poser Pro Pack, Poser 4 will be able to share character animation, figure bending, scene and key frame data for integration within LightWave 6 and 3D Studio Max R3 -- two of the most widely recognized professional 3D applications. Web developers looking to include photo realistic 3D object and 3D character content will be able to export Metastream 3 files. For web-deployable 2D content, the Poser Pro Pack will export vector converted Flash animations from any Poser scene. The Poser Pro Pack also includes Poser 4 updates, interface improvements and features such as: multiple view ports of a scene, motion blur for final rendered animations and Python scripting environment controls.
