This real universe may be somewhere between expansion and contraction, depending upon which cosmologist you follow, but our virtual world may also have a limit before everything crashes back in on itself. Normally if we want a background, we use props such as the infinity cove or cyclorama or square with a backdrop to give a sense of spatiousness, but that world is still only a few poser units deep. With the microcosm or a town set or props such as Serena's Island or various terrains, one can have a bit more room to work with, and a real irregular surface to collect shadows, but usually need to add some sky or distant landscape. I prefer working with terrains because they don't look as fake as a flat background. Has anybody determined what the absolute maximum size of the Poser universe is in PNUs? (or any other measurement?) Height as well as depth? Patricia is having crashes (I'm pulling this out into its own thread for more help): "Yes, I used a tiling prop, but I've forgotten whose it was and, way back then, you hadn't yet initiated me into the proper Poser canon wherein all DLed freebie props are carefully attributed to their creators. I found a black and white checkered floortile pattern, too, with lots of repeats, but it still required 20 of the props to give me enough distance." What I wonder is if she has gone beyond the edge of the universe that Poser can calculate... and it is dividing by an irrational number or or eating its tail or making tea instead of adding vast expanses of floor tile. So, how big is our world? Is it different with the different versions of Poser? Thanks! Carolly the Curious
