Quote - Noel, why wouldn't an animated collada file work? I've been able to use animated collada files in V7, whithout the need of a script...

Each frame of the fluid is a different mesh (with a different no. of vertices and faces) and I wasn't aware that COLLADA supported that kind of animation, but if it does and both RealFlow/Blender and Vue support that mode, then that would be good (but I suspect memory usage would still be a concern).
