You're right there war2. Being able to animate a landscape enviroment in Vue5 & zoom down for a macro shot in C4 because they will both utilize the same HDR maps is gonna be something magical. With the physics engine in C4 for that special touch. I was speculating as to whether the crossover via Lightwave format may even allow Vue5 files to take on the physics behaviours in C4. Both apps will now support import/export of lightwave files, could take the whole Vue5 scene over to C4 & really go to town! Rokol.
