I did a lot of experimenting with the alpha and to be quite honest, I reckon it's unrealistic to expect to import poser lights and have them work exactly the way they do in poser. With the alpha, I ended up doing all the lighting inside DS. It's a 'diiferent' lighting system to poser's. In some ways, far better, in other, not so easy (at least, not so easy to get used to, anyway). The point lights in DS are terrific. Finally, we can make a light bulb actually work by just clicking on a point light and positioning it inside the bulb. Re the content thing - There seems to have been some problem with the installer adding an extra content directory. You just need to empty the content sub-folder into the content folder itself and it works. I didn't download any content, so I didn't have this problem. Another oddity I've found is that when I apply a MAT file, nothing changes.... until I move a camera or something in the doc window, then the change appears. Small bug, I guess. mac
