Maybe, that this could be done easy with the Game machine plugin - you don´t render all the scene, but it is done by a pc (in real time) where you perform that 3D scene. I´m not found in that, but maybe somebody who works with Blender could help... Than is only neccessairy to convert it to a 3D belb format and add the 3D sound. But there is a question, if this is still about TG :@)
