We'vw been chatting about this program in the News Forum. I've been using Strata for quite a few years now and am more than willing to answer any questions that may come up. There are also tutorials and cool articles available at 3d.com. If you want to see what Strata can do then (here comes the plug) go to Hat Check Kelly at www.ultranet.com/~jje1/ And FYI the original Myst was done solely using Strata software. Such volumetrics! jje
