Papervision3D is an open source 3D rendering engine for Adobe Flash, which means that Electric Rain has little or no influence over where it goes in the future. It also means that there will be things that don't always work exactly as we would like. Having said that, we will be in regular contact with the guys developing Papervision3D and it is our goal to make Swift 3D the premier tool for creating Papervision3D projects. They are already giving us great feedback on where we need to take Swift 3D in the near future.
