P.S. It is easier than it sounds - you don't have to parent EVERYTHING - just the few things that are parented to the UNIVERSE. All the things that are conformed to or parented to one of those objects will follow their parent, so they do not need to be re-parented to the box. It would be great if a script could be written that would do that for us. Especially if it allowed us to choose the scale factor. Many scenes do well at 500% but I've found that some require scaling as high as 1000% (10x) to be effective. The only things that do NOT scale with this technique are P5 procedural textures (fBm, brick, cloud, weave, tile etc.) - they will have to be scaled manually, but even without re-scaling sometimes you get decent results, so its best to do a trial render before taking the time to adjust them. As for render times, there WILL be differences. Some things will render faster, and some things will render slower - averaging out to be about the same as the unscaled scene. One thing that will really slow things down is close-ups of high resolution textures.
