nruddock: I'm very impressed to see what you have done in such a short amount of time. I assume from what you wrote, the first .obj of the sequence is imported and scaled/positioned, with the remaining automatically frames aligning to this? It is possible to place the sequence anywhere in the scene as long as the first frame is set? The scaling shouldn't be much of a problem to sort out in RealFlow3 - in there the scale value can be adjusted. Very well done - for a long time, some said it couldn't be done!
