My longest render for an image was about 3 minutes.The rendertime depends on the imageresolution,and how complex the whole scene is.Transparencies slow the renderengine down. So if you make a animation with about 180 frames you can calculate yourself, how long render will last. But normally the rendering of an image is about 1 minute. And thats fast , take Bryce and rendering will last 10 times longer( Poser is not a real render)
